| inferior thalamic peduncle | A large fibre bundle emerging from the anterior part of the thalamus in the ventral direction, in part joining the medial fibres of the internal capsule, in other part curving laterally around the medial margin of the capsule into the innominate substance. Many of its fibres establish a reciprocal connection of the mediodorsal nucleus of the thalamus with the orbital gyri of the frontal lobe, but numerous other fibres constitute a conduction system from the amygdala and olfactory cortex to the mediodorsal nucleus. See: ansa peduncularis. Synonym: pedunculus thalami inferior. (05 Mar 2000) |

| thalamic | <anatomy> Of or pertaining to a thalamus or to thalami. Source: Websters Dictionary (01 Mar 1998) |
| thalamic fasciculus | Nerve fibres forming a composite bundle containing cerebellothalamic (crossed) and pallidothalamic (uncrossed) fibres that is insinuated between the thalamus and zona incerta. See: fields of Forel. Synonym: fasciculus thalamicus. (05 Mar 2000) |
| thalamic gustatory nucleus | The small ventral region of the ventral posteromedial nucleus of thalamus in which the fibres of the gustatory lemniscus and secondary trigeminal tracts terminate; it projects to the lower part of the postcentral gyrus of the cerebral cortex. Synonym: arcuate nucleus, nucleus arcuatus thalami, nucleus arcuatus, semilunar nucleus of Flechsig, thalamic gustatory nucleus. (05 Mar 2000) |
| thalamic nuclei | Several groups of nuclei in the thalamus that serve as the major relay centres for sensory impulses in the brain. (12 Dec 1998) |
| thalamic syndrome | <syndrome> A syndrome produced by infarction of the postero-inferior thalamus causing transient hemiparesis, severe loss of superficial and deep sensation with preservation of crude pain in the hypalgic limbs which frequently have vasomotor or trophic disturbances. Synonym: Dejerine-Roussy syndrome. (05 Mar 2000) |
| thalamic tenia | The sharp edge or angle between the superior and medial surface of the thalamus on either side; to it is attached the epithelial lamina forming the roof of the third ventricle. Synonym: tenia ventriculi tertii, thalamic tenia. (05 Mar 2000) |
| lateral thalamic peduncle | The massive group of fibres that emerges from the laterodorsal side of the thalamus to join the corona radiata; it reciprocally connects the lateral nucleus and the geniculate bodies of the thalamus with the corresponding regions of the cerebral cortex. Synonym: pedunculus thalami lateralis. (05 Mar 2000) |
| accessory meningeal branch of middle meningeal artery | <anatomy, artery> A branch of either the middle meningeal or maxillary artery in the infratemporal fossa and passing superiorly through the foramen ovale to supply the trigeminal ganglion, dura mater and inner table of bone. Synonym: ramus meningeus accessorius arteriae meningeae mediae. (05 Mar 2000) |
| acetabular branch | An arterial branch that supplies the acetabulum; two arteries, the obturator and the medial femoral circumflex, have such branches. Synonym: ramus acetabularis, acetabular artery, arteria acetabuli. (05 Mar 2000) |
| acromial branch of suprascapular artery | <anatomy, artery> Branch of suprascapular artery which pierces the origin of the trapezius muscle to run to the acromion; anastomoses, acromial branch of thoracoacromial artery. Synonym: ramus acromialis arteriae suprascapularis. (05 Mar 2000) |
| acromial branch of thoracoacromial artery | <anatomy, artery> A branch of the thoracoacromial artery that runs over the coracoid process and under the deltoid muscle. Synonym: ramus acromialis arteriae thoracoacromialis, acromial artery. (05 Mar 2000) |
| anastomotic branch | The anastomotic branch, a blood vessel that interconnects two neighboring vessels. It should not be used for the nervous system, because there is no analogy between a vascular anastomosing branch and a connection between nerves or their subdivisions. Synonym: ramus anastomoticus. (05 Mar 2000) |
| anastomotic branch of middle meningeal artery to lacrimal artery | <anatomy, artery> A branch of the middle meningeal artery arising in the cranial cavity which runs anteriorly through the superior orbital fissure to anastomose with the lacrimal artery. See: orbital branch of middle meningeal artery. Synonym: ramus anastomoticus arteriae meningeae mediae cum lacrimali. (05 Mar 2000) |
| anterior basal branch | Anterior basal branch of basal parts of the inferior lobar branches of the right and left pulmonary arteries, and superior basal branches of the right and left inferior pulmonary veins. Synonym: ramus basalis anterior. (05 Mar 2000) |
