| 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) |
| septal defect, atrial | A hole in the septum, the wall, between the atria, the upper chambers of the heart. Commonly called an asd. Asds are a major class of heart deformity that is present at birth (congenital cardiac malformation). (12 Dec 1998) |
| septal defect, ventricular | A hole in the interventricular septum, the wall between the ventricles, the lower chambers of the heart. Commonly called a vsd. Vsds are a common class of heart deformity that is present at birth (congenital cardiac malformation). (12 Dec 1998) |
| 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) |
| neural tube defect | <neurology, paediatrics> Abnormal development during embryonic life of the neural tube producing congenital malformations of the nervous system due to closure failure of the neural tube. The structure gives rise to the central nervous system (the brain and spinal cord), and failure to close results in anencephaly (absence of the cranial vault and absence of most or all of the cerebral hemispheres of the brain) and spina bifida or meningomyelocele (open spina with exposure and protusion of the spinal cord). The risk of neuroal tube defects can be decreased by the mother taking folic acid during pregnancy. (04 Jul 1999) |
| neuropathies, hereditary motor and sensory | A group of slowly progressive inherited disorders in which the predominant involvement is the peripheral motor neurons with lesser involvement of the peripheral sensory neurons. Neuronal degeneration and atrophy are characteristic of these disorders. Some of the associated characteristics are phytanic acid excess, optic atrophy, and retinitis pigmentosa. (12 Dec 1998) |
| neuropathies, hereditary sensory and autonomic | A group of inherited disorders in which there is selective involvement of the peripheral sensory and autonomic neurons and degeneration of fibres by axonal atrophy and degeneration. Five types of disorders have been described and classified type I through type v. (12 Dec 1998) |
