| piriform cortex | The olfactory cortex, corresponding to the rostral half of the uncus; receiving its major afferents from the olfactory bulb, it is classified as allocortex. See: cerebral cortex. Synonym: olfactory cortex, piriform area. (05 Mar 2000) |
| motor cortex | Area of the frontal lobe concerned with primary motor control. It lies anterior to the central sulcus. (12 Dec 1998) |
| plexiform layer of cerebral cortex | Layer 1 of the cortex cerebri. Synonym: plexiform layer of cerebral cortex. (05 Mar 2000) |
| cortex | <anatomy> The outer layer of an organ or other body structure, as distinguished from the internal substance. Origin: L. Corticalis = bark, rind, shell (18 Nov 1997) |
| cortex cerebelli | The thin gray surface layer of the cerebellum, consisting of an outer molecular layer or stratum moleculare, a single layer of Purkinje cells (the ganglionic layer), and an inner granular layer or stratum granulosum. Synonym: cortex cerebelli. (05 Mar 2000) |
| cortex cerebri | The outer portion of the brain, consisting of layersof nerve cells and the pathways that connect them. The cerebralcortex is the part of the brain in which thought processes take place.In Alzheimer's disease, nerve cells in the cerebral cortex die. (22 May 1997) |
| cortex lentis | The softer, more superficial part of the lens of the eye that encloses the central part or nucleus; its refractive power is less than that of the nucleus. Synonym: cortex lentis. (05 Mar 2000) |
| cortex nodi lymphatici | The outer portion of the lymph node underneath its capsule, consisting of fibrous trabeculae separating densely packed masses of lymphocytes arranged in nodules and separated from the trabeculae and capsule by lymph sinuses. Synonym: cortex nodi lymphatici. (05 Mar 2000) |
| cortex of hair shaft | The principal structural component of the hair shaft, composed of closely packed fusiform keratinised cells and invested by the cuticula pili. (05 Mar 2000) |
| cortex of lens | The softer, more superficial part of the lens of the eye that encloses the central part or nucleus; its refractive power is less than that of the nucleus. Synonym: cortex lentis. (05 Mar 2000) |
| cortex of lymph node | The outer portion of the lymph node underneath its capsule, consisting of fibrous trabeculae separating densely packed masses of lymphocytes arranged in nodules and separated from the trabeculae and capsule by lymph sinuses. Synonym: cortex nodi lymphatici. (05 Mar 2000) |
| cortex of ovary | The layer of the ovarian stroma lying immediately beneath the tunica albuginea, composed of connective tissue cells and fibres, among which are scattered primary and secondary (antral) follicles in various stages of development; the cortex varies in thickness according to the age of the individual, becoming thinner with advancing years. Synonym: cortex ovarii. (05 Mar 2000) |
| cortex of thymus | The outer part of a lobule of the thymus; it surrounds the medulla and is composed of masses of closely packed lymphocytes. (05 Mar 2000) |
| cortex ovarii | The layer of the ovarian stroma lying immediately beneath the tunica albuginea, composed of connective tissue cells and fibres, among which are scattered primary and secondary (antral) follicles in various stages of development; the cortex varies in thickness according to the age of the individual, becoming thinner with advancing years.
