| proto-oncogene proteins c-kit | Tyrosine kinase membrane receptors which are the natural ligands for mast cell growth factor (steel factor). This interaction is crucial for the development of haematopoietic, gonadal, and pigment stem cells. (12 Dec 1998) |
| disaster supplies kit | You and your family can cope best by preparing for disaster before it strikes. One way to prepare is by assembling a Disaster Supplies Kit. Once disaster hits, you won't have time to shop or search for supplies. But if you've gathered supplies in advance, your family can endure an evacuation or home confinement. For useful information, see the MedicineNet site on YOUR FAMILY DISASTER SUPPLIES KIT. (12 Dec 1998) |

| kit | <oncogene> An oncogene, identified in feline sarcoma, encoding a tyrosine protein kinase that acts on stem cell factor. (18 Nov 1997) |
| kit fox | <zoology> Kit fox, a small burrowing fox (Vulpes velox), inhabiting the region of the Rocky Mountains. It is brownish gray, reddish on the breast and flanks, and white below. Called also swift fox. (11 Mar 1998) |
| absolute system of units | A system based on absolute units accepted as being fundamental (length, mass, time) and from which other units (force, energy or work, power) are derived; such system's in common use are the foot-pound-second, centimeter-gram-second, and meter-kilogram-second system's. (05 Mar 2000) |
| absorbent system | <anatomy> The tissues and organs (including the bone marrow, spleen, thymus and lymph nodes) that produce and store cells that fight infection and the network of vessels that carry lymph. (12 May 1997) |
| alimentary system | The organs that are responsible for getting food into and out of the body and for making use of food to keep the body healthy. These include the mouth, oesophagus, stomach, liver, gallbladder, pancreas, small intestine, colon, and rectum. (12 Dec 1998) |
| anterolateral system | A composite bundle of fibres, located in the ventrolateral part of the lateral funiculus, containing spinothalamic, spinohypothalamic, spinoreticular, and spinomesencephalic (spinotectal, spinal to periaqueductal grey, etc.) fibres; occupies the combined areas of the spinal white matter historically divided into anterior and lateral spinothalamic tracts; located in white matter ventral to the denticulate ligament, hence the anatomical basis for the anterolateral cordotomy; concerned with the transmission of nociceptive and thermal information and with crude (nondiscriminative) touch. (05 Mar 2000) |
| anti-allergic and respiratory system agents | A collective term for drugs used to treat allergic reactions as well as those drugs that produce an effect on the respiratory system. (12 Dec 1998) |

| association system | Groups or tracts of nerve fibres interconnecting different regions of one and the same major subdivision of the central nervous system, such as the various areas of the cerebral cortex or the various segments of the spinal cord. (05 Mar 2000) |
| autonomic nervous system | <anatomy> Neurons that are not under conscious control, comprising two antagonistic components, the sympathetic and parasympathetic nervous systems. The autonomic nervous system regulates key functions including the activity of the cardiac (heart) muscle, smooth muscles (e.g., of the gut), and glands. The autonomic nervous system has two divisions: 1. The sympathetic nervous system that accelerates the heart rate, constricts blood vessels, and raises blood pressure. 2. The parasympathetic nervous system slows the heart rate, increases intestinal and gland activity, and relaxes sphincter muscles. (03 Jul 1999) |
| autonomic nervous system diseases | Diseases that have their major effects on the autonomic nervous system. The autonomic nervous system may be seriously affected in many other disorders including other peripheral nervous system diseases, infectious diseases (e.g., tetanus, diphtheria), immunologic diseases (e.g., acquired immunodeficiency syndrome), and systemic disorders (e.g., diabetic neuropathy, amyloid neuropathy, thyroid diseases). Disorders of central autonomic control also contribute substantially to a wide variety of problems (e.g., eating disorders, panic disorder, water-electrolyte imbalance, cardiovascular diseases).
