| cranial nerve XI | <anatomy, nerve> The accessory nerve enervates the sternocleidomastoid muscles and the trapezius muscles. Lesions of the eleventh result in drooping of the shoulder and inability to rotate the head away from the affected side. Synonym: cranial nerve XI. (27 Sep 1997) |
|---|---|
| cranial nerve XII | <anatomy, nerve> The hypoglossal nerve enervates the muscles of the tongue. Lesions of the twelfth cranial nerve result in deviation of the tongue toward the paralysed side and thick speech. Synonym: cranial nerve XII. (27 Sep 1997) |
| cranial nerves | <anatomy> There are 12 cranial nerves. The olfactory nerve, optic nerve, occulomotor nerve, trochlear nerve, trigeminal nerve, abducent nerve, facial nerve, vestibulocochlear nerve, glossopharyngeal nerve, vagus nerve, accessory nerve and the hypoglossal nerve. (18 Nov 1997) |
| cranial neuropore | The temporary opening at the extreme rostral (cephalic) end of the early embryonic forebrain; closes at the 20th somite stage. Synonym: anterior neuropore, cranial neuropore. (05 Mar 2000) |
| cranial root of accessory nerve | <anatomy, nerve> The roots of the accessory nerve which arise from the medulla; the nerve fibres of the cranial root join the intracranial portion of the vagus nerve and are distributed to the pharyngeal plexus, providing the motor innervation of the soft palate (except the tensor veli palati) and the pharynx. Synonym: pars vagalis nervi accessorii, radices craniales, accessory portion of spinal accessory nerve, cranial roots, vagal part of accessory nerve, vagal part. (05 Mar 2000) |

| cranial sinuses | Large endothelium-lined venous channels situated between the two layers of the dura mater; they are devoid of valves. (12 Dec 1998) |
| cranial sutures | A type of fibrous joint between bones of the head. (12 Dec 1998) |
| cranial synchondroses | The cartilaginous joints of the skull; these include sphenoethmoidal synchondrosis, spheno-occipital synchondrosis, sphenopetrosa synchondrosis, petro-occipital synchondrosis, anterior intraoccipital and posterior intraoccipital synchondrosis. Synonym: synchondroses cranii. (05 Mar 2000) |
| cranial vault | Those bones of the skull enclosing the brain, as distinguished from the bones of the face. Synonym: braincase, cranial vault, cranium cerebrale, cerebral cranium. Origin: neuro-+ G. Kranion, skull (05 Mar 2000) |
| cranial vertebra | A segment of the skull regarded as homologous with a segment of the vertebral column. (05 Mar 2000) |
| cranialis | <anatomy> Pertaining to the cranium or to the anterior (in animals) or superior (in humans) end of the body. Origin: L. Cranialis (18 Nov 1997) |
| craniamphitomy | A decompression operation in which the entire circumference of the calvarium is divided. Origin: G. Kranion, skull, + amphi, around, + tome, cutting (05 Mar 2000) |
| Craniata | Synonym: Vertebrata. Origin: Mediev. L. Cranium, fr. G. Kranion, skull (05 Mar 2000) |
| craniectomy | <procedure, surgery> Surgery performed on the skull where pieces of bone are removed to gain access to the brain and the bone pieces are not replaced. (16 Dec 1997) |
