  • The fiber from lateral part of lateral geniculate nucleus is carried through the retrolenticular portion. (wikipedia.org)
  • acoustic fibers, from the lateral lemniscus to the temporal lobe fibers that pass from the occipital and temporal lobes to the pontine nuclei The superior parts of both the anterior and posterior limbs and the genu of the internal capsule are supplied by the lenticulostriate arteries, which are branches of the M1 segment of the middle cerebral artery. (wikipedia.org)
  • The caudate nucleus narrows rapidly as it proceeds backwards on the lateral part of the floor of the lateral ventricle. (co.ma)
  • The roof and lateral wall of this portion of the ventricular cavity are formed by the tapetum of the corpus callosum. (co.ma)
  • In frontal sections through the occipital lobe this is seen as a thin but distinct layer of white fibres, which lies immediately lateral to the ependyma and to the medial side of a much larger strand of fibres in the medullary substance of the occipital lobe, viz. (co.ma)
  • It runs parallel and lateral to the collateral sulcus (which is also known as the medial occipitotemporal sulcus). (radiopaedia.org)
  • ACA and MCA → medial + lateral lenticulostriate aa. (radiologykey.com)
  • the body of the corpus callosum has been turned over to the left. (co.ma)
  • corpus callosum. (co.ma)
  • The central part or body of the cavity is likewise roofed by the corpus callosum. (co.ma)
  • On the medial side it is bounded by the posterior part of the septum pellucidum which attaches the fornix to the inferior surface of the corpus callosum. (co.ma)
  • The uppermost of these is termed the bulb of the cornu (bulbus cornu posterioris), and is produced by the fibres of the radiation of the corpus callosum as they curve abruptly backwards from the lower part of the splenium of the corpus callosum into the occipital lobe. (co.ma)
  • The black substance in the ventral midbrain or the nucleus of cells containing the black substance. (lookformedical.com)
  • the sublenticular portion is beneath the lenticular nucleus and are tracts involved in the auditory pathway from the medial geniculate nucleus to the primary auditory cortex (Brodmann areas 41 and 42) The genu is the flexure of the internal capsule. (wikipedia.org)
  • The anterior half of the posterior limb contains fibers of the corticospinal tract and corticobulbar tract (in an anteroposterior somatotropic arrangement), as well as corticorubral fibres (passing from the frontal lobe to the red nucleus) that accompany the corticospinal tract. (wikipedia.org)
  • The medial posterior choroidal artery is a small branch (often multiple - 40% of hemispheres) usually arising from the P2 segment of the PCA . (radiopaedia.org)
  • they originate in the motor part of the cerebral cortex and after passing downward through the base of the cerebral peduncle with the cerebrospinal fibers, undergo decussation and end in the motor nuclei of the cranial nerves of the opposite side. (wikipedia.org)
  • From here, the meningeal layer passes downwards to surround the pituitary gland, thus forming the medial wall of the cavernous sinus. (radiopaedia.org)
  • they originate in the motor part of the cerebral cortex and after passing downward through the base of the cerebral peduncle with the cerebrospinal fibers, undergo decussation and end in the motor nuclei of the cranial nerves of the opposite side. (wikipedia.org)
  • The basal nuclei (or ganglia) are situated inside the white matter in the basal part of the cerebral hemisphere and large subcortical masses of grey matter. (earthslab.com)
  • The striatum gets fibres primarily from the cerebral cortex, thalamus and substantia nigra. (earthslab.com)
  • The fibres, which follow the inner curve of the caudate nucleus and terminate into septal area, anterior perforated substance and anterior hypothalamic nuclei, originate from amygdaloid body form stria terminalis. (earthslab.com)
  • The anterior half of the posterior limb contains fibers of the corticospinal tract and corticobulbar tract (in an anteroposterior somatotropic arrangement), as well as corticorubral fibres (passing from the frontal lobe to the red nucleus) that accompany the corticospinal tract. (wikipedia.org)
  • Developmentally it is related to the basal nuclei but functionally it's included in the limbic system and therefore, shares its functions. (earthslab.com)
  • Reddish nucleus is a cigar shaped mass of grey matter which appears ovoid in cross section. (earthslab.com)
  • It contains the corticobulbar tract, which carries upper motor neurons from the motor cortex to cranial nerve nuclei that mainly govern motion of striated muscle in the head and face. (wikipedia.org)
