| cortical part of middle cerebral artery | <anatomy, artery> See: middle cerebral artery. Synonym: pars corticalis arteriae cerebralis mediae. (05 Mar 2000) |
|---|---|
| cortical reaction | The reaction of an egg cell to fertilization which changes its surface cell membrane and prevents additional sperm cells from entering (among other things). (09 Oct 1997) |
| cortical sensibility | The integration of sensory stimuli by the cerebral cortex. (05 Mar 2000) |
| cortical substance | The superficial thin layer of compact bone. Synonym: substantia corticalis, cortical substance. (05 Mar 2000) |
| cortical vesicle | A vesicle, or membrane-bound bubble, in an animal egg cell that releases proteases and other enzymes immediately after fertilization, chiefly to change the egg's surface cell membrane so that no more sperm cells can enter. (09 Oct 1997) |
| hyperostosis, cortical, congenital | A disease of young infants characterised by soft tissue swellings over the affected bones, fever, and irritability, and marked by periods of remission and exacerbation. (12 Dec 1998) |
| infantile cortical hyperostosis | Neonatal subperiosteal bone formation over many bones, especially the mandible and clavicles and the shafts of long bones; it follows fever, usually appearing before 6 months of age and disappearing during childhood. Synonym: Caffey's disease, Caffey's syndrome, Caffey-Silverman syndrome. (05 Mar 2000) |
| fibrous cortical defect | A common 1 to 3 cm defect in the cortex of a bone, most commonly the lower femoral shaft of a child, filled with fibrous tissue. Nonosteogenic or nonossifying fibroma by convention refers to lesions greater than 3 cm in diameter. See: nonossifying fibroma. Synonym: nonosteogenic fibroma. (05 Mar 2000) |
| laminar cortical necrosis | The breaking down of a definite cell layer in the cerebral cortex, encountered typically after temporary cardiac arrest or perinatal hypoxia. (05 Mar 2000) |
| laminar cortical sclerosis | A degeneration of nerve fibres in the corona radiata in a laminar pattern. (05 Mar 2000) |
| absent nasal septum | <radiology> Cocaine, Wegener's (midline lethal granuloma), surgery, trauma, syphilis, sarcoid (12 Dec 1998) |
| alveolar septum | The tissue intervening between two adjacent pulmonary alveoli; it consists of a close-meshed capillary network covered on both surfaces by very thin alveolar epithelial cells, one of the bony partitions between the tooth sockets. Synonym: septum interalveolare, alveolar septum, septal bone. (05 Mar 2000) |
| anterior vein of septum pellucidum | Vein draining the anterior part of the transparent septum; it empties into the superior thalamostriate vein. Synonym: vena septi pellucidi anterior. (05 Mar 2000) |
| aortopulmonary septum | The spiral septum which, during development, separates the truncus arteriosus into a ventral pulmonary trunk and dorsal aorta. See: bulbar ridge. (05 Mar 2000) |
| atrial septum | The wall between the two upper chambers (the right and left atrium) of the heart. (12 Dec 1998) |
