Asymmetric Tonic Neck Reflex: From 1 Different Sources
a primitive reflex that is present from birth but should disappear by six months of age. If the infant is lying on its back and the head is turned to one side, the arm and leg on the side to which the head is turned should straighten, and the arm and leg on the opposite side should bend (the ‘fencer’ position). Persistence of the reflex beyond six months is suggestive of *cerebral palsy.

A condition in which the head is twisted to one side. It may be caused by the contraction of a scar, such as that resulting from a burn or by paralysis of some of the muscles; as a result of injury at birth; or trauma to the area later in life. Treatment is by an orthopaedic collar, heat or ULTRASOUND, or PHYSIOTHERAPY. Sometimes a local injection of BOTULISM toxin will produce temporary relief. Rarely, surgery is necessary.

When a sharp body is drawn along the sole of the foot, instead of the toes bending down towards the sole as usual, the great toe is turned upwards and the other toes tend to spread apart. After the age of about two years, the presence of this re?ex indicates some severe disturbance in the upper part of the central nervous system. The Babinski re?ex may occur transiently during COMA or after an epileptic ?t and need not indicate permanent damage.... babinski reflex
A bitter-tasting substance or formula used to increase a deficient appetite, improve the acidity of stomach secretions and protein digestion, and slightly speed up the orderly emptying of the stomach. A good bitter tonic should possess little, if any, drug effect, only acting on oral and stomach functions and secretions. Dry mouth, bad gums, teeth problems with bad breath in the morning, and weak digestion, often with constipation, are the main deficiency symptoms. A bitter tonic has little effect in normal digestion. Example: Gentiana... bitter tonic
Cleavers tea has been used for centuries, even in ancient Greece. It is considered probably the best tonic for the lymphatic system available. Discover all of its benefits and learn how to make the most of this type of tea.
Description of Cleavers tea
Cleavers is an annual green plant that grows mostly in Britain, North America and Eurasia regions. The green to white flowers look like small balls and they are very sticky, similar to the leaves.
Scientifically named gallium aparine, cleavers is also called bedstraw, barweed, catchweed, grip grass. The entire cleavers plant is used in herbal medicine and is harvested just before it blooms in early summer.
The active constituents of cleavers tea are chlorophyll, citric acide, rubichloric acid, galiosin and tannins. To benefit the most from these constituents, you can consume cleavers, usually found in the form of tea, extracts, capsule, or fresh for many cooking recipes. The roasted seeds are used as a coffee substitute and the young leaves can be eaten like spinach.
Cleavers tea has a slightly bitter taste and no odor.
Cleavers tea brew
For a tasty Cleavers tea, take 2 to 3 teaspoons of the dried above-ground parts of the plant and infuse them in a 250 mg cup of hot water for 10 or 15 minutes. You may add sugar or honey to improve its taste and drink up to three times per day.
Cleavers tea Benefits
Cleavers tea is a strong detoxifying for the lymphatic system. It is diuretic, thus treating most of urinary tract infections.
It cleans the blood, the liver and kidneys. The tea can be used together with Uva Ursi or Echinacea for best results.
Applied topically, Cleavers tea helps in the treatment of many skin conditions like acne, eczema, psoriasis, dandruff, itchy scalp, sunburns or even wounds.
Cleavers tea can be used as a facial tonner because it helps clear the complexion.
Cleavers tea Side effects
Cleavers tea has no known side effects. Though it is widely safe, children, pregnant or nursing women should drink it with precaution.
Cleavers tea can surely be included in a healthy lifestyle. As long as you don’t exaggerate with it, you can enjoy the benefits of this tea and even use the plant to prepare many tasty recipes and salads.... cleavers tea - best tonic for the lymphatic system available in nature
The development of a speci?c response by an individual to a speci?c stimulus. The best-known conditioned re?ex is the one described by Ivan Pavlov, in which dogs that became accustomed to being fed when a bell was sounded salivated on hearing the bell, even if no food was given. The conditioned re?ex is an important part of behavioural theory.... conditioned reflex

Assessment of victims of major trauma must include maintenance of their airways and breathing. Any false teeth, vomitus and foreign bodies should be removed, and the response to digital stimulation of the posterior pharyngeal wall – the ‘gag re?ex’ – assessed. Even with a normal gag re?ex, the airway may be seriously threatened if vomiting occurs. During the initial stages of resuscitation, careful and constant supervision of the airway is essential, with a high-volume sucker immediately available. If the gag re?ex is absent or impaired, an endotracheal tube should be inserted (see ENDOTRACHEAL INTUBATION).... gag reflex

Pupillary constriction in the EYE in response to light. The direct light re?ex involves pupillary constriction in the eye into which a light is shone; the consensual light re?ex is the pupillary constriction that occurs in the other eye. The a?erent or inward pathway of the re?ex is via the optic nerve, and the e?erent or outward pathway is via the occulomotor nerve.... light reflex
A primitive REFLEX ACTION occurring in newly born infants in response to a sudden movement or noise. Also known as the startle re?ex, the baby will throw its arms and legs wide and sti?en its body. This is followed by ?exion of the arms and legs. The re?ex disappears by four months; its persistence suggests a possible neurological condition such as CEREBRAL PALSY.... moro reflex

An automatic movement in response to a stimulus that is present in newborn infants but disappears during the first few months after birth. Primitive reflexes are believed to represent actions that were important in earlier stages of human evolution. They include the grasp reflex when something is placed in the hand and the rooting reflex, which enables a baby to find the nipple. The rooting reflex can be evoked by touching the baby’s cheek with the fingertip. These reflexes are tested after birth to give an indication of the condition of the nervous system.... reflex, primitive

an operation that involves an incision through the bladder neck that is extended into the prostate to relieve *lower urinary tract symptoms. This procedure is usually performed under a general or spinal anaesthetic through a cystoscope. It is not as extensive as a transurethral resection of the prostate and is therefore associated with a comparatively lower incidence of side-effects.... bladder neck incision
reflex control of the heart rate. Sensory fibres in the walls of the heart are stimulated when the heart rate increases above normal. Impulses are sent to the cardiac centre in the brain, stimulating the vagus nerve and leading to slowing of the heart rate.... cardiac reflex
a reflex in which the response occurs not to the sensory stimulus that normally causes it but to a separate stimulus, which has been learnt to be associated with it. In Pavlov’s classic experiments, dogs learned to associate the sound of a bell with feeding time and would salivate at the bell’s sound whether food was then presented to them or not.... conditioned reflex
reflex blinking of both eyes normally elicited by lightly touching the cornea of one eye. This reflex is lost in deep coma, during general anaesthesia, and in death; it is therefore one of the tests used to confirm brainstem death.... corneal reflex
a superficial reflex in males elicited by stroking the inner side of the upper thigh with a sharp object. If the reflex is intact the scrotum on that side is pulled upwards as the cremaster muscle contracts. Absence or reduction of both cremasteric reflexes indicates an upper *motor neuron lesion; absence of the reflex on one side suggests a lower motor neuron lesion at the level of the first lumbar spinal nerve.... cremasteric reflex

involuntary grasping in response to anything that touches the palm of the hand. This is a normal reflex in babies that is lost in early childhood. In adults it is a sign of damage to the *prefrontal lobes of the brain.... grasp reflex
the normal physiological reflex to breathe out when the breath is held in inspiration and to breathe in when it is held in exhalation. [H. E. Hering (1866–1948), German physiologist; J. Breuer (1842–1925), German physician]... hering–breuer reflex
an abnormal reflex elicited by lightly placing the index finger across the chin of the patient and tapping it with a tendon hammer while the jaw hangs loosely open. A brisk upward movement of the jaw indicates an upper *motor neuron disorder above the brainstem.... jaw-jerk reflex
a reflex seen in normal babies from three months until one year, when it disappears. If the baby is held horizontally, face down, it will straighten its legs and back and try to lift up its head. The presence of this reflex beyond one year may be suggestive of a developmental disorder.... landau reflex

involuntary contraction of the stapedius and/or tensor tympani muscles in the middle ear in response to various stimuli. The stapedius contracts in response to sound (see stapedial reflex). The tensor tympani is thought to contract during chewing. The sound-evoked middle ear reflex can be detected using a *tympanometer.... middle ear reflex
(startle reflex) a primitive reflex seen in newborn babies in response to the stimulus of a sudden noise or movement: the baby will fling its arms and legs wide and will appear to stiffen; the arms and legs are then drawn back into flexion. The Moro reflex should disappear spontaneously by four months. Its presence beyond this age is suggestive of an underlying neurological disorder, such as cerebral palsy. [E. Moro (1874–1951), German paediatrician]... moro reflex
a reflex action of the intestine in which a physical stimulus causes the intestine to contract above and relax below the point of stimulation.... myenteric reflex
see stretch reflex.... myotatic reflex
(knee jerk) reflex contraction of the quadriceps (thigh) muscle so that the leg kicks, elicited in a patient sitting with one knee crossed over the other by sharply tapping the tendon of the muscle below the kneecap. The reflex is mediated through nerves emanating from the third and fourth lumbar spinal levels (see spinal nerves). This is a test of the connection between the sensory nerves attached to stretch receptors in the muscle, the spinal cord, and the motor neurons running from the cord to the thigh muscle, all of which are involved in the reflex. The patellar reflex is reduced or absent when there is disease or damage of the spinal cord at or below the level of the reflex and exaggerated in disorders above the level of the reflex.... patellar reflex
see gag reflex.... pharyngeal reflex
a reflex obtained by drawing a bluntly pointed object (such as a key) along the outer border of the sole of the foot from the heel to the little toe. The normal flexor response is a bunching and downward movement of the toes. An upward movement of the big toe is called an extensor response (or Babinski reflex or response). In all persons over the age of 18 months this is a sensitive indication of damage to the *pyramidal system in either the brain or spinal cord.... plantar reflex
(light reflex) the reflex change in the size of the pupil according to the amount of light entering the eye. Bright light reaching the retina stimulates nerves of the *parasympathetic nervous system, which cause the pupil to contract. In dim light the pupil opens, due to stimulation of the *sympathetic nervous system. See also iris.... pupillary reflex
flexion of the forearm (and sometimes also of the fingers) that occurs when the lower end of the radius is tapped. It is due to contraction of the brachioradialis muscle, which is stimulated by tapping its point of insertion in the radius.... radial reflex

the nervous circuit involved in a *reflex, being at its simplest a sensory nerve with a receptor, linked at a synapse in the brain or spinal cord with a motor nerve, which supplies a muscle or gland (see illustration). In a simple reflex (such as the *patellar reflex) only two neurons may be involved, but in other reflexes there may be several *interneurons in the arc.... reflex arc

a primitive reflex present in newborn babies: if the cheek is stroked near the mouth, the infant will turn its head to the same side to suckle.... rooting reflex
reflex contraction of the stapedius muscle in the middle ear, attached to the *stapes bone, in response to loud sounds. This protects the cochlea from noise damage by limiting the amount of sound that is transmitted via the stapes. The reflex can be measured using a *tympanometer.... stapedial reflex

the constriction of the shaft of the *humerus, below the head. It is frequently the point at which fracture of the humerus occurs.... surgical neck
(Adie’s pupil) a pupil that is dilated as a result of damage to the nerves supplying the ciliary muscle and iris. It reacts poorly to light but may constrict better for near vision, with slow redilation on refixation at a distance. The tonic pupil is sensitive to dilute 0.1% pilocarpine drops, which cause marked constriction but have little effect on a normal pupil. The tonic pupil may become miotic (see miosis) over time.... tonic pupil
