| internuncial neuron | A neuron interposed between and connecting two other neuron's. Synonym: intercalary neuron. (05 Mar 2000) |
|---|---|
| facilitator neuron | <physiology> A neuron whose firing enhances the effect of a second neuron on a third. This allows the effects of neuronal activity to be modulated. (18 Nov 1997) |
| unipolar neuron | A neuron whose cell body emits a single axonal process resulting from the fusion of two polar processes during development; at a variable distance from the cell body, the process divides into a peripheral axon branch extending outward as a peripheral afferent (sensory) nerve fibre, and a central axon branch that enters into synaptic contact with neuron's in the spinal cord or brainstem. With the single known exception of the neuron's composing the mesencephalic nucleus of the trigeminus, unipolar neuron's are the exclusive neural elements of the sensory ganglia. The lack of dendritic processes of these primary sensory neuron's is only apparent: the dendritic pole of the unipolar neuron is represented by the unmyelinated terminal ramifications of the peripheral axon branch. Synonym: pseudounipolar cell, pseudounipolar neuron, unipolar cell. (05 Mar 2000) |
| arterial arch of upper eyelid | Formed by communicating branches of the medial and lateral palpebral arteries. Often two arches are present, one located near the free border of the tarsal plate, the other along the upper border of the tarsus. Synonym: arcus palpebralis superior. (05 Mar 2000) |
| bones of upper extremity | The bones of the upper and lower arm. They include the clavicle and scapula. (12 Dec 1998) |
| bones of upper limb | These include the superior limb girdle (scapula and clavicle) and the skeleton of the free superior limb (humerus, radius, ulna, wrist bones, metacarpus, and bones of the fingers). Synonym: ossa membri superioris, bones of superior limb. (05 Mar 2000) |
| regions of upper limb | The topographic divisions of the upper limb: deltoid, arm, elbow, forearm, carpal region, and hand. Synonym: regiones membri superioris, regions of superior limb. (05 Mar 2000) |
| denture, complete, upper | A complete denture replacing all the natural maxillary teeth and associated maxillary structures. It is completely supported by the oral tissue and underlying maxillary bone. (12 Dec 1998) |
| quadrate muscle of upper lip | Composed of three heads usually described as three separate muscles; they are the caput angulare or levator labii superioris alaeque nasi muscle; caput infraorbitale or levator labii superioris muscle; caput zygomaticum or zygomaticus minor muscle. Synonym: quadrate muscle of upper lip. (05 Mar 2000) |
| elevator muscle of upper eyelid | <anatomy, muscle> Origin, orbital surface of the lesser wing of the sphenoid, above and anterior to the optic canal; insertion, skin of eyelid, tarsal plate, and orbital walls, by medial and lateral expansions of the aponeurosis of insertion; action, raises the upper eyelid; nerve supply, oculomotor. Synonym: musculus levator palpebrae superioris, elevator muscle of upper eyelid, musculus orbitopalpebralis, palpebralis. (05 Mar 2000) |
| elevator muscle of upper lip | <anatomy, muscle> Origin, maxilla below infraorbital foramen; insertion, orbicularis oris of upper lip; action, elevates upper lip; nerve supply, facial. Synonym: musculus levator labii superioris, caput infraorbitale quadrati labii superioris, elevator muscle of upper lip. (05 Mar 2000) |
| elevator muscle of upper lip and wing of nose | <anatomy, muscle> Origin, root of nasal process of maxilla; insertion, wing of nose and orbicularis oris muscle of upper lip; action, elevates upper lip and wing of nose; nerve supply, facial. Synonym: musculus levator labii superioris alaeque nasi, caput angulare quadrati labii superioris, elevator muscle of upper lip and wing of nose. (05 Mar 2000) |
| endoscopy, upper | A procedure that enables the examiner (usually a gastroenterologist ) to examine the oesophagus (swallowing tube ), stomach, and duodenum ( first portion of small bowel ) using a thin flexible tube (a scope ) that can be looked through or seen on a TV monitor. Also known as oesophagogastroduodenoscopy or EGD. (12 Dec 1998) |
| tubercle of upper lip | The slight projection on the free edge of the centre of the upper lip at the lower extent of the philtrum. Synonym: tuberculum labii superioris, procheilon, prochilon, tubercle of upper lip. (05 Mar 2000) |
| joints of free upper limb | The joints uniting the bones of the free superior limb girdle; they are the shoulder joint, elbow joint, radioulnar joints, and joints of the wrist and hand. Synonym: articulationes membri superioris liberi, joints of free superior limb, juncturae membri superioris liberi. (05 Mar 2000) |
