the means whereby an undesirable impulse or emotion can be avoided or controlled. Defence mechanisms are regarded as normal forms of self-protection; however, used excessively, they can become pathological. Many defence mechanisms have been described, including *repression, *projection, *reaction formation, *sublimation, and *splitting.
Many glands which produce HORMONES are in?uenced by other hormones, particularly those secreted by the HYPOTHALAMUS (a controlling centre in the brain) and the PITUITARY GLAND. If the amount of hormone produced by a gland rises, negative feedback mechanisms operate by instructing the pituitary gland, via the hypothalamus, to produce less of the stimulating hormones. This cuts activity in the target gland. Should the amount of hormone produced fall, the feedback mechanism weakens with the result that the output of stimulating hormones increases.... feedback mechanism
These are UK bodies that provide doctors with advice and, where appropriate, ?nancial support in defending claims for medical negligence in their clinical practice. They also advise doctors on all legal aspects of their work, including patients’ complaints, and provide representation for members called to account by the GENERAL MEDICAL COUNCIL (GMC) or other regulatory body. The sharp rise in claims for medical negligence in the NHS in the 1980s persuaded the UK Health Departments to introduce a risk-pooling system called the Clinical Negligence Scheme for Trusts, and the defence societies liaise with this scheme when advising their doctor members on responding to claims of negligence (see MEDICAL LITIGATION; MEDICAL NEGLIGENCE).... medical defence organisations
