| Wernicke's region | The region of the cerebral cortex thought to be essential for understanding and formulating coherent, propositional speech; it encompasses a large region of the parietal and temporal lobes near the lateral sulcus of the left cerebral hemisphere; corresponding approximately to Brodmann's areas 40, 39, and 22. Synonym: sensory speech centre, Wernicke's area, Wernicke's field, Wernicke's region, Wernicke's zone. (05 Mar 2000) |
| constant region | The stem and forking part of the Y-shaped antibody protein, consisting of amino acid chains, that is exactly the same in all antibody molecules within the same individual. (The ends of the Y-shaped molecule will vary widely between different antibodies). (09 Oct 1997) |
| popliteal region | The diamond-shaped space posterior to the knee joint bounded superficially by the diverging biceps femoris and semimembranosus muscles above and inferiorly by the two heads of the gastrocnemius muscle; deeply, the fossa is bound superiorly by the diverging supracondylar lines of the femur and the soleal line of the tibia inferiorly. Contents: tibial nerve, popliteal artery, vein, fat. Synonym: fossa poplitea, poples, ham, popliteal region, popliteal space, popliteus. (05 Mar 2000) |
| C region | <immunology> The parts of the heavy or light chains of immunoglobulin molecules that are of constant sequence, in contrast to variable or V regions. The constancy of sequence is relative because there are several constant region genes and alleles thereof (see allotypes), but within one animal homozygous at the light and heavy chain constant region genes all immunoglobulin molecules of any one class have constant sequences in their C regions. The constant region sequences for the various different types of immunoglobulin for example IgG, IgA, etc. Will vary. (18 Nov 1997) |
| posterior antebrachial region | The area between the radial and ulnar borders of the forearm posteriorly. Synonym: regio antebrachialis posterior, facies antebrachialis posterior, posterior antebrachial region, posterior surface of forearm. (05 Mar 2000) |
| posterior brachial region | The back of arm. Synonym: facies brachialis posterior, regio brachialis posterior, posterior brachial region, posterior surface of arm. (05 Mar 2000) |
| posterior carpal region | The posterior part of the wrist. Synonym: regio carpalis posterior. (05 Mar 2000) |
| posterior cubital region | The back of the elbow. Synonym: facies cubitalis posterior, regio cubitalis posterior, posterior cubital region, posterior surface of elbow. (05 Mar 2000) |
| posterior hypothalamic region | Caudal portions of the hypothalamus located internally in the area of the mamillary body, includes medial, intermediate, and lateral mamillary nuclei and the posterior hypothalamic nuclei. Synonym: posterior hypothalamic area. (05 Mar 2000) |
| posterior knee region | The posterior region of the knee, including the popliteal fossa. Synonym: regio genus posterior. (05 Mar 2000) |
| posterior neck region | The back of neck, including the suboccipital region. Synonym: regio nuchalis, nuchal region, posterior neck region, regio cervicalis posterior. (05 Mar 2000) |
| posterior region of arm | The back of arm. Synonym: facies brachialis posterior, regio brachialis posterior, posterior brachial region, posterior surface of arm. (05 Mar 2000) |
