What is the Brachium pontis?

What is the Brachium pontis?

The middle cerebellar peduncles, also known as the brachium pontis, are paired structures connecting the cerebellum to the pons.

Where is the Brachium pontis located?

Cerebellum and Precerebellar Nuclei The middle cerebellar peduncle, or the brachium pontis, is located laterally. The middle peduncle is purely afferent. Its origin from the contralateral pontine nuclei was first demonstrated by Vejas (1885) in chronic experiments in the rabbit.

What does the superior cerebellar peduncle do?

The superior cerebellar peduncles, also known as the brachium conjunctivum, are paired white matter fiber tracts that connect the cerebellum with the midbrain. The superior cerebellar peduncle contains vital afferent and efferent fibers including cerebellothalamic, cerebellorubral and ventrospinocerebellar tracts.

What is cerebellar peduncle?

: any of three large bands of nerve fibers that join each hemisphere of the cerebellum with the parts of the brain below and in front: a : one connecting the cerebellum with the midbrain.

What is left Brachium pontis?

Anatomical terms of neuroanatomy The middle cerebellar peduncles (brachium pontis) are paired structures (left and right) that connect the cerebellum to the pons and are composed entirely of centripetal fibers, i.e. incoming fibers.

What is the structure that fills the space between the superior cerebellar peduncles?

The space between the superior cerebellar peduncle and the inferior medullary velum is called the superolateral recess.

What does the middle cerebellar peduncle control?

Clinical neuroanatomy The middle cerebellar peduncle is the largest and contains only afferent fibres from the pontine nucleus. This pontocerebellar tract provides an important connection between the cerebral cortex and cerebellum and modulates skilled activities of hands and fingers.

Which tract passes through the middle cerebellar peduncle?

corticopontocerebellar pathway
The middle cerebellar peduncles contain afferent white matter projection fibers which originate in contralateral pontine nuclei. The corticopontocerebellar pathway is the predominant afferent fiber pathway that passes through the MCP.

What does the middle cerebellar peduncle connect?

The middle cerebellar peduncle connects the transverse fibers of the pons with the cerebellum, which is entirely afferent to the cerebellum.

What are the causes of basal ganglia T2 hyperintensity?

The causes of basal ganglia T2 hyperintensity can be remembered using the mnemonic LINT: lymphoma; ischemia. hypoxia; venous infarction (internal cerebral vein thrombosis) neurodegenerative / metabolic. autoimmune encephalitis (e.g. anti-D2 dopamine antibody encephalitis) Creutzfeldt-Jakob disease; extrapontine myelinolysis

How are the basal ganglia and thalamus affected?

Both the basal ganglia and thalamus may be affected by other systemic or metabolic disease, degenerative disease, and vascular conditions. Focal flavivirus infections, toxoplasmosis, and primary central nervous system lymphoma may also involve both deep gray matter structures.

What causes bilaterally symmetric diffuse abnormalities of the basal ganglia?

Bilaterally symmetric diffuse abnormalities involving the lentiform and caudate nuclei in their entirety typically suggest systemic or metabolic causes, whereas asymmetric, focal, or discrete lesions affecting only part of the basal ganglia tend to indicate involvement by infections or neoplasms.

How is computed tomography used to diagnose basal ganglia?

Although magnetic resonance (MR) imaging is the modality of choice for evaluating the basal ganglia, computed tomography (CT) may be the first line of investigation, particularly in emergency situations in which patients present with altered sensorium or acute-onset seizures.
