| sensory nerve | <anatomy, nerve> An afferent nerve conveying impulses that are processed by the central nervous system so as to become part of the organism's perception of self and its environment. (05 Mar 2000) |
|---|---|
| sensory neuron | 1. <anatomy> A neuron that receives input from sensory cells. 2. <physiology> Sensory cells such as cutaneous mechanoreceptors and muscle receptors. (18 Nov 1997) |
| sensory neuronopathy | Neuronopathy confined to dorsal root and gasserian ganglia. (05 Mar 2000) |
| sensory nuclei | A group of cell bodies that receive afferent (sensory) input from the periphery. (05 Mar 2000) |
| sensory paralysis | Loss of sensation; anaesthesia. (05 Mar 2000) |
| sensory precipitated epilepsy | Seizures which are induced by peripheral stimulation; e.g., audiogenic, laryngeal, photogenic, or other stimulation. Synonym: sensory precipitated epilepsy. (05 Mar 2000) |
| sensory receptors | Peripheral endings of afferent neurons. (05 Mar 2000) |
| sensory 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. (05 Mar 2000) |
| sensory root of pterygopalatine ganglion | <anatomy, nerve> The ganglionic branches, two short sensory branches of the maxillary nerve in the pterygopalatine fossa, the fibres of which pass through the pterygopalatine ganglion without synapse. Synonym: radix sensoria ganglii pterygopalatini, rami ganglionici nervi maxillaris, rami ganglionares, nervi pterygopalatini, nervi sphenopalatini, pterygopalatine nerves, sensory root of pterygopalatine ganglion. (05 Mar 2000) |
| sensory root of trigeminal nerve | <anatomy, nerve> The large sensory root of the trigeminal (or fifth cranial) nerve, extending from the semilunar ganglion into the pons through the middle cerebellar peduncle or brachium pontis, immediately lateral to the small motor root. Synonym: radix sensoria nervi trigemini, portio major nervi trigemini. (05 Mar 2000) |
| sensory speech centre | The region of the cerebral cortex thought to be essential for understanding and formulating coherent, propositional speech; it encompasses a large region of the parietal and temporal lobes near the lateral sulcus of the left cerebral hemisphere; corresponding approximately to Brodmann's areas 40, 39, and 22. Synonym: sensory speech centre, Wernicke's area, Wernicke's field, Wernicke's region, Wernicke's zone. (05 Mar 2000) |
| sensory system agents | Drugs that act on neuronal sensory receptors resulting in an increase, decrease, or modification of afferent nerve activity. (12 Dec 1998) |
| sensory thresholds | The minimum amount of stimulus energy necessary to elicit a sensory response. (12 Dec 1998) |
| sensory tract | See: lemniscus. (05 Mar 2000) |
| somatic sensory cortex | Somatosensory cortex, the region of the cerebral cortex receiving the somatic sensory radiation from the ventrobasal nucleus of the thalamus; it represents the primary cortical processing mechanism for sensory information originating at the body surfaces (touch) and in deeper tissues such as muscle, tendons, and joint capsules (position sense); it corresponds approximately to Brodmann's areas 1, 2, 3 on the postcentral gyrus. Synonym: somesthetic area. (05 Mar 2000) |
