The ability of an individual or a defined population to obtain or receive appropriate health care. This involves the availability of programmes, services, facilities and records. Access can be influenced by such factors as finances (insufficient monetary resources); geography (distance to providers); education (lack of knowledge of services available); appropriateness and acceptability of service to individuals and the population; and sociological factors (discrimination, language or cultural barriers).
The 11th cranial nerve. Unlike the other cranial nerves, most of the accessory nerve originates from the spinal cord. The small part of the nerve that originates from the brain supplies many muscles of the palate, pharynx (throat), and larynx (voice box). Damage to this part of the nerve may cause difficulty in speaking and swallowing. The spinal part of the nerve supplies large muscles of the neck and back, notably the sternomastoid and trapezius. Damage to the spinal fibres of the nerve paralyses these muscles.... accessory nerve
muscles of the shoulder girdle and chest wall that (in addition to the intercostal muscles and the diaphragm) are utilized during *respiratory distress to help the flow of air in and out of the lungs. Use of these muscles can be a sign of the degree of difficulty that the patient is in, for example in cases of asthma or *airway obstruction.... accessory muscles
an extra electrical conduction pathway between the atria and ventricles, anatomically separate from the *atrioventricular node, that predisposes to *re-entry tachycardia. The pathway conducts faster than the atrioventricular node, giving rise to pre-excitation recognized by a characteristic delta wave at the beginning of the QRS complex on the electrocardiogram in normal rhythm. The presence of this pathway, with the occurrence of intermittent tachycardias, is known as the *Wolff-Parkinson-White syndrome.... accessory pathway
