| cortical osteitis | Periostitis with involvement of the superficial layer of bone. (05 Mar 2000) |
|---|---|
| cortical part | cortical part |
| 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) |
| corticalization | In phylogenesis, the migration of function from subcortical centres to the cortex. Synonym: encephalization, telencephalization. (05 Mar 2000) |
| corticalosteotomy | An osteotomy through the cortex at the base of the dentoalveolar segment, which serves to weaken the resistance of the bone to the application of orthodontic forces. (05 Mar 2000) |
| corticectomy | Removal of a specific portion of the cerebral cortex. Origin: cortic-+ G. Ektome, excision (05 Mar 2000) |
| cortices | Plural of cortex. (05 Mar 2000) |
| corticifugal | Passing in a direction away from the outer surface; denoting especially nerve fibres conveying impulses away from the cerebral cortex. Synonym: corticoefferent, corticofugal. Origin: L. Cortex, rind, bark, + fugio, to flee (05 Mar 2000) |
| corticipetal | <physiology> Passing in a direction toward the outer surface; denoting nerve fibres conveying impulses toward the cerebral cortex. Synonym: corticoafferent. Origin: L. Cortex, rind, bark, + peto, to seek (05 Mar 2000) |
| corticoafferent | <physiology> Passing in a direction toward the outer surface; denoting nerve fibres conveying impulses toward the cerebral cortex. Synonym: corticoafferent. Origin: L. Cortex, rind, bark, + peto, to seek (05 Mar 2000) |
| corticobulbar fibre | <physiology> Nerve fibre's projecting from the motor and somatic sensory cortex to the rhombencephalon. Included in this corticofugal fibre system are corticoreticular fibre's terminating in the reticular formation of the rhombencephalon, and corticonuclear fibre's to the motor nuclei innervating the musculature of the face, tongue, and jaws, and to some fibre's of the rhombencephalic sensory relay nuclei. They terminate directly on some motor cranial nerve nuclei, in the reticular formation, and on sensory relay nuclei, such as the cuneate nucleus and gracile nucleus and the spinal trigeminal nucleus. See: corticobulbar tract. (05 Mar 2000) |
