The brainstem (or brain stem) is the posterior stalk-like part of the brain that connects the cerebrum with the spinal cord. [1] In the human brain the brainstem is composed of the midbrain, the pons, and the medulla oblongata. [1] The midbrain is continuous with the thalamus of the diencephalon through the tentorial notch, and sometimes the ...
54376. Anatomical terms of bone. [edit on Wikidata] The clivus (/ ˈklaɪvəs /, [1] Latin for "slope") or Blumenbach clivus is a part of the occipital bone at the base of the skull. [2] It is a shallow depression behind the dorsum sellae of the sphenoid bone. It slopes gradually to the anterior part of the basilar occipital bone at its ...
77719. Anatomical terms of neuroanatomy. [edit on Wikidata] The reticular formation is a set of interconnected nuclei in the brainstem that spans from the lower end of the medulla oblongata to the upper end of the midbrain. [2] The neurons of the reticular formation make up a complex set of neural networks in the core of the brainstem. [3]
The middle cerebellar peduncle is the largest of the three cerebellar peduncles. It connects the pons and cerebellum.It consists almost entirely of fibers passing from the pons to the cerebellum (fibrocerebellar fibers); the fibers arise from the pontine nuclei and decussate within the pons before entering the peduncle [1] to end in the contralateral cerebellar hemisphere.
62394. Anatomical terms of neuroanatomy. [edit on Wikidata] The cerebral peduncles (In Latin, ped- means 'foot'.) are the two stalks that attach the cerebrum to the brainstem. [1] They are structures at the front of the midbrain which arise from the ventral pons and contain the large ascending (sensory) and descending (motor) tracts that run to ...
The pedunculopontine nucleus (PPN) or pedunculopontine tegmental nucleus (PPT or PPTg) is a collection of neurons located in the upper pons in the brainstem. [1][2] It is involved in voluntary movements, [3] arousal, and provides sensory feedback to the cerebral cortex and one of the main components of the reticular activating system. [4][5] It ...
Cerebellar peduncles. The cerebellar peduncles are three paired bundles of fibres that connect the cerebellum to the brain stem. [1] Superior cerebellar peduncle is a paired structure of white matter that connects the cerebellum to the mid-brain. Middle cerebellar peduncles connect the cerebellum to the pons and are composed entirely of ...
The parabrachial nuclei, also known as the parabrachial complex, are a group of nuclei in the dorsolateral pons that surrounds the superior cerebellar peduncle as it enters the brainstem from the cerebellum. They are named from the Latin term for the superior cerebellar peduncle, the brachium conjunctivum. In the human brain, the expansion of ...
