| compartment | <biology> In the insect wing, for example: there are two compartments, anterior and posterior, each containing several clones, but clones do not cross the boundary. It seems from studies with homoeotic mutants that cells in different compartments are expressing different sets of genes. The evidence for such developmental compartments in vertebrates is sparse at present. (18 Nov 1997) |

| compartment syndrome | <syndrome> A group of symptoms which indicate a nerve, blood vessel or tendon is being constricted due to swelling within a closed anatomic space. A compartment syndrome may occur in an extremity after trauma (fracture) or inflammation (carpal tunnel syndrome). Some medications can also precipitate this condition. Symptoms include numbness, tingling, pain or loss of movement in an extremity. Surgery may be indicated if symptoms are severe or prolonged. (05 Jan 1998) |
| compartment syndromes | Conditions in which increased pressure within a limited space compromises the circulation and function of tissue within that space. Compartmentation involves mainly the leg but also involved are the forearm, arm, thigh, shoulder, and buttock. Some of the causes of increased pressure are trauma, tight dressings, haemorrhage, and exercise. Sequelae include nerve compression, paralysis, and contracture. (12 Dec 1998) |
| compartmental model | <epidemiology> A mathematical model which divides hosts into different compartments according to their infectious state. A typical model for microparasites might be an SEIR model. Sometimes referred to as a prevalence model. (05 Dec 1998) |
| compartmental syndrome | <syndrome> A condition in which increased pressure in a confined anatomical space adversely affects the circulation and threatens the function and viability of the tissues therein. (05 Mar 2000) |
| compartmentation | The division of a cell into different regions, either structurally or biochemically. (05 Mar 2000) |
| anterior compartment syndrome | <syndrome> Rapid swelling, increased tension, pain, and ischemic necrosis of the muscles of the anterior tibial compartment of the leg, often following excessive exertion. (12 Dec 1998) |
|---|---|
| anterior tibial compartment syndrome | <syndrome> Ischemic necrosis of the muscles of the anterior tibial compartment of the leg, presumed due to compression of arteries by swollen muscles following unaccustomed exertion. (05 Mar 2000) |
| plasmatic compartment | Compartment surrounded by a double biomembrane and containing polynucleotides (e.g., mitochondria). (05 Mar 2000) |
| polyclonal compartment | When the progeny of several cells occupy an area or volume with a defined boundary, it is referred to as a polyclonal compartment, for example clones lying close to the mid line of the wing of Drosophila. (18 Nov 1997) |
| nonplasmatic compartment | Compartment surrounded by a single biomembrane (e.g., vacuoles, lysosomes). (05 Mar 2000) |
| double compartment hydrocephalus | Independent supra-and infra-tentorial hydrocephalus usually due to a veil occlusion of the aqueduct of Sylvius. (05 Mar 2000) |
