Brodmann area 33, also known as pregenual area 33, is a subdivision of the cytoarchitecturally defined cingulate region of cerebral cortex.It is a narrow band located in the anterior cingulate gyrus adjacent to the supracallosal gyrus in the depth of the callosal sulcus, near the genu of the corpus callosum. [1]
Lesions of the genu of the internal capsule affect fibers of the corticobulbar tract. [citation needed] The primary motor cortex sends its axons through the posterior limb of the internal capsule. Lesions, therefore, result in a contralateral hemiparesis or hemiplegia. While symptoms of weakness due to an isolated lesion of the posterior limb ...
These are the rostrum, the genu, the trunk or body, and the splenium. [4] Fibres from the trunk and the splenium, known together as the tapetum ("carpet"), form the roof of each lateral ventricle. [6] The front part of the corpus callosum, towards the frontal lobes, is called the genu ("knee").
The cingulate cortex is a part of the brain situated in the medial aspect of the cerebral cortex. The cingulate cortex includes the entire cingulate gyrus, which lies immediately above the corpus callosum, and the continuation of this in the cingulate sulcus. The cingulate cortex is usually considered part of the limbic lobe.
The first-order neurons from the trigeminal ganglion enter the pons and synapse in the principal (chief sensory) nucleus or spinal trigeminal nucleus.Axons of the second-order neurons cross the midline and terminate in the ventral posteromedial nucleus of the contralateral thalamus (as opposed to the ventral posterolateral nucleus, as in the dorsal column medial lemniscus (DCML) system).
The function and role of quiescent hepatic stellate cells is unclear. Recent evidence suggests a role as a liver-resident antigen-presenting cell, presenting lipid antigens to and stimulating proliferation of NKT cells. [7] When the liver is damaged, stellate cells can change into an activated state.
The term limbic system was introduced in 1952 by Paul MacLean to describe the set of structures that line the deep edge of the cortex (Latin limbus meaning border): [18] These include the hippocampus, cingulate cortex, olfactory cortex, and amygdala. Paul MacLean later suggested that the limbic structures comprise the neural basis of emotion.
The Codex Sinaiticus (Shelfmark: London, British Library, Add MS 43725), designated by siglum א [Aleph] or 01 (in the Gregory-Aland numbering of New Testament manuscripts), δ 2 (in the von Soden numbering of New Testament manuscripts), also called Sinai Bible, is a fourth-century Christian manuscript of a Greek Bible, containing the majority of the Greek Old Testament, including the ...
