| cranial index | The ratio of the maximal breadth to the maximal length of the skull, obtained by the formula: (breadth × 100)/length. (05 Mar 2000) |
|---|---|
| cranial irradiation | The exposure of the head to roentgen rays or other forms of radioactivity for therapeutic or preventive purposes. (12 Dec 1998) |
| cranial mononeuropathy III | (compression type) A disorder involving vision changes and eyelid drooping associated with a decreased functioning of cranial nerve III. Damage is usually caused by compression of the nerves from localised lesions or a swelling in the area of the nerve. Examples include cerebral aneurysms and tumours Symptoms include a drooping eyelid and double vision. (diabetic type) A disorder involving vision changes and eyelid drooping associated with a decreased functioning of cranial nerve III as a complication of diabetes. Symptoms include a drooping eyelid and double vision. Good control of blood sugars can reduce the incidence of this complication. (27 Sep 1997) |
| cranial mononeuropathy vi | A disorder involving vision changes that are associated with the decreased function of cranial nerve VI. Often this form of nerve damage is associated with diabetes, tumours of the VI nerve or increased intracranial pressure. Trauma and stroke may also damage the VI cranial nerve. Symptoms include double vision when looking to one side. (27 Sep 1997) |
| cranial mononeuropathy vii | A disorder which involves drooping of the face and the decreased ability to move one side of the face. Causes include isolated damage to the facial nerve, HIV infection, sarcoidosis and Lyme disease. Bell's palsy is a dysfunction of the facial nerve for reason unknown. (27 Sep 1997) |
| cranial nerve I | <anatomy, nerve> The olfactory nerve carries impulses for the sense of smell. Synonym: cranial nerve I. (27 Sep 1997) |
| cranial nerve II | <anatomy, nerve> The optic nerve. The nerve carrying impulses for the sense of sight. Projection from the vertebrate retina to the midbrain. Embryologically, a CNS tract rather than a peripheral nerve. Popular experimental preparation for studies of regeneration of retino tectal projections in lower vertebrates and also for studies of glial cell lineage in CNS. Synonym: cranial nerve II. (18 Nov 1997) |
| cranial nerve III | <anatomy, nerve> The occulomotor nerve is responsible for motor enervation of upper eyelid muscle, extraocular muscle and pupillary muscle. Lesions of the oculomotor nerve results in ptosis (dropping eyelid), deviation of the eyeball outward, double vision and a dilated pupil. Synonym: cranial nerve III. (27 Sep 1997) |
| cranial nerve IV | <anatomy, nerve> The trochlear nerve controls an extraocular muscle. Lesions of this nerve will result in rotation of the eyeball upward and outward (and double vision). Synonym: cranial nerve IV. (27 Sep 1997) |
| cranial nerve IX | <anatomy, nerve> The glossopharyngeal nerve enervates muscles involved in swallowing and taste. Lesions of the ninth nerve result in difficulty swallowing and disturbance of taste. Synonym: cranial nerve IX. (27 Sep 1997) |
| cranial nerve neoplasms | Neoplasms of any of the cranial nerves. (12 Dec 1998) |
| 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 nerve V | <anatomy, nerve> The trigeminal nerve is responsible for sensory enervation of the face and motor enervation to muscles of mastication (chewing). There are three divisions of the fifth cranial nerve, ophthalmic, maxillary and mandibular. Lesions of the sensory root to the trigeminal nerve can result in pain or loss of sensation in the face. Lesion of the motor root result in deviation of the jaw toward the paralysed side and difficulty chewing. Synonym: cranial nerve V. (27 Sep 1997) |
| cranial nerve VI | <anatomy> The abducent nerve enervates a muscle which moves the eyeball. Lesions of the sixth cranial nerve result in deviation of the eyeball outward and double vision. Synonym: cranial nerve VI. (27 Sep 1997) |
| cranial nerve VII | <anatomy, nerve> The facial nerve enervates the muscles of the face (facial expression). Lesion of the facial nerve cause a drooping to one side of the face, inability to wrinkle the forehead, inability to whistle, inability to close the eye and deviation of the mouth to the unaffected side. Synonym: cranial nerve VII. (27 Sep 1997) |
