| temporal sensing | <technique> Mechanism of gradient sensing in which the value of some environmental property is compared with the value at some previous time, the cell having moved position between the two samplings. Initial movement is random, until the second observation is made the gradient cannot be detected. See spatial and pseudospatial sensing mechanisms. Bacterial chemotaxis (so called) is based on this mechanism. (18 Nov 1997) |
|---|---|
| temporal squama | The broad, flat, thin (scale-like) anterior and superior portion of the temporal bone forming part of the lateral wall of the cranial vault. Synonym: pars squamosa ossis temporalis, squama temporalis, temporal squama. (05 Mar 2000) |
| temporal surface | The surface of a bone which contributes to the temporal fossa, namely, the greater wing of the sphenoid, the squamous part of the temporal, frontal and zygomatic bones. Synonym: facies temporalis. (05 Mar 2000) |
| temporal veins | See: middle temporal vein, deep temporal veins, superficial temporal veins. (05 Mar 2000) |
| temporal venules of retina | See: inferior temporal venule of retina, superior temporal venule of retina. (05 Mar 2000) |
| third temporal convolution | A sagittal convolution on the inferolateral border of the temporal lobe of the cerebrum, separated from the middle temporal gyrus by the inferior temporal sulcus. On the inferior surface of the temporal lobe it is separated from the medial occipitotemporal gyrus by the occipitotemporal sulcus. It includes the lateral occipitotemporal gyrus. Synonym: gyrus temporalis inferior, inferior temporal convolution, third temporal convolution. (05 Mar 2000) |
| transverse temporal convolutions | Two or three convolutions running transversely on the upper surface of the temporal lobe bordering on the lateral (sylvian) fissure, separated from each other by the transverse temporal sulci. Synonym: gyri temporales transversi, Heschl's gyri, transverse temporal convolutions. (05 Mar 2000) |
| transverse temporal gyri | Two or three convolutions running transversely on the upper surface of the temporal lobe bordering on the lateral (sylvian) fissure, separated from each other by the transverse temporal sulci. Synonym: gyri temporales transversi, Heschl's gyri, transverse temporal convolutions. (05 Mar 2000) |
| transverse temporal sulci | The shallow sulci that demarcate the transverse temporal gyri on the opercular surface of the superior temporal gyrus. Synonym: sulci temporales transversi. (05 Mar 2000) |
| epilepsy, temporal lobe | Epileptic seizures characterised by simple partial seizures, complex partial seizures, and secondary generalised seizures, or combinations of these. Seizures may present with autonomic and/or psychic symptoms and certain sensory phenomena such as olfactory and auditory. most common is an epigastric rising sensation. Some seizures may begin with motor arrest and continue with oro-alimentary automatisms (with other automatisms following). Attacks are followed by amnesia and recovery is gradual. Usually, there is a history of febrile seizures in the individual or a history of seizures in the family. Seizures occur in clusters, randomly, or at intervals. (12 Dec 1998) |
| tympanic part of temporal bone | The bony plate forming the greater part of the anterior wall of the bony part of the external acoustic meatus and the tympanic cavity and the posterior wall of the mandibular fossa. Synonym: pars tympanica ossis temporalis, tympanic part of temporal bone. (05 Mar 2000) |
| tympanic plate of temporal bone | The bony plate forming the greater part of the anterior wall of the bony part of the external acoustic meatus and the tympanic cavity and the posterior wall of the mandibular fossa. Synonym: pars tympanica ossis temporalis, tympanic part of temporal bone. (05 Mar 2000) |
| jugular notch of temporal bone | The notch in the temporal bone which forms one boundary of the jugular foramen. Synonym: incisura jugularis ossis temporalis. (05 Mar 2000) |
| first temporal convolution | A longitudinal gyrus on the lateral surface of the temporal lobe between the lateral (sylvian) fissure and the superior temporal sulcus. Synonym: gyrus temporalis superior, first temporal convolution, superior temporal convolution. (05 Mar 2000) |
| frontal branch of superficial temporal artery | <anatomy, artery> Terminal branch of superficial temporal artery (with parietal branch) supplying anterolateral scalp and underlying musculature, periosteum, and outer table of cranium; anastomosis: across midline with contralateral partner; supratrochlear and supraorbital arteries. Synonym: ramus frontalis arteriae temporalis superficialis. (05 Mar 2000) |
