| long root of ciliary ganglion | Sensory fibres passing from the eyeball through the ciliary ganglion to their cell bodies in the trigeminal ganglion via the nasociliary nerve. Synonym: radix sensoria ganglii ciliaris, ramus communicans nervi nasociliaris cum ganglio ciliari, radix nasociliaris, long root of ciliary ganglion, nasociliary root, radix longa ganglii ciliaris.

| barotrauma, otic | See: Barotitis. (12 Dec 1998) |
| otic | Relating to the ear. Origin: G. Otikos, fr. Ous, ear (05 Mar 2000) |
| otic abscess | A cerebral abscess usually involving the temporal lobe or cerebellar hemisphere, due to extension of suppuration of the middle ear. Synonym: otogenous abscess. (05 Mar 2000) |
| otic barotrauma | Middle ear problems due to changing atmospheric pressures, as when a plane descends to land. The problems include ear pain, ringing, diminished hearing and, sometimes, dizziness. Alternate terms include aerotitis: aerotitis media, barotitis, barotitis media. (12 Dec 1998) |
| otic capsule | The cartilage capsule surrounding the inner ear mechanism; in elasmobranchs, it remains cartilaginous in the adult; in the embryos of higher vertebrates, it is cartilaginous at first but later becomes bony (at approximately 23 weeks in humans). (05 Mar 2000) |
| otic pits | Paired depressions, one on either side of the head of the embryo, marking the location of the future auditory vesicles. Synonym: otic pits. (05 Mar 2000) |
| otic placodes | Paired ectodermal placode's that sink below the general level of the superficial ectoderm to form the auditory vesicles. Synonym: otic placodes. (05 Mar 2000) |
| otic vesicle | One of the paired sacs of invaginated ectoderm that develop into the membranous labyrinth of the internal ear. Synonym: acoustic vesicle, otic vesicle. (05 Mar 2000) |
| ganglia of sympathetic trunk | The clusters of postganglionic neurons located at intervals along the sympathetic trunks, including the superior cervical, middle cervical, and cervicothoracic (stellate) ganglion, the thoracic, lumbar, and sacral ganglia, and the ganglion impar. Synonym: ganglia trunci sympathici, paravertebral ganglia. (05 Mar 2000) |
| ganglia, sympathetic | Ganglia of the sympathetic nervous system including the paravertebral and the prevertebral ganglia. Among these are the sympathetic chain ganglia, the superior, middle, and inferior cervical ganglia, and the aorticorenal, coeliac, and stellate ganglia. (12 Dec 1998) |
| reflex sympathetic dystrophy | A syndrome of pain and tenderness, usually to a hand or foot, associated with vasomotor instability, skin changes and rapid development of bony demineralisation (osteoporosis). Frequently will follow a localised trauma, stroke or peripheral nerve injury. (27 Sep 1997) |
| reflex sympathetic dystrophy syndrome | <syndrome> A condition that features a group of typical symptoms, including pain (often burning type), tenderness, and swelling of an extremity associated with varying degrees of sweating, warmth and/or coolness, flushing, discoloration, and shiny skin. (12 Dec 1998) |
| communicating branches of sympathetic trunk | Short nerves arising from the lateral aspect of the sympathetic trunk conducting nonmyelinated postsynaptic sympathetic nerve fibres from the sympathetic trunk to the initial portions of all 31 pairs of ventral primary rami of spinal nerves for distribution by all parts (including the dorsal primary ramus) of the spinal nerve. The gray rami are the parietal branches of the sympathetic trunks since all postsynaptic fibres to be distributed to the body wall (including limbs) must pass through them. Synonym: communicating branches of sympathetic trunk, communicating rami of sympathetic trunk. (05 Mar 2000) |
