cerebellum Flashcards
The ___ is located in the posterior cranial fossa below the tentorium cerebelli.
cerebellum
The cerebellum has a cortex of ___ matter surface with ___ matter on the inside.
- gray matter
- white matter
The cerebellum functions include ___.
- regulating equilibrium
- controls muscle tone and posture
- provides motor coordination for voluntary movements
The posterolateral fissure separates the ___ from the body of the cerebellum.
flocculonodular lobe
The ___ peduncle has inputs from the spinal cord and brainstem
inferior cerebellar (restiform body)
What is the job of the inferior cerebellar peduncle.
- monitors muscle and limb movement
The ___ body interconnects the vestibular nuclei and the cerebellum.
juxtarestiform
The ___ is the largest peduncle which is located lateral to the pons.
Middle cerebellar peduncle (brachium pontis)
The middle cerebellar peduncle receives afferents from ___, and relays ___ signals from the cortex.
- contralateral basis pontis
- motor
The superior cerebellar peduncle (brachium conjunctivum) sends efferents to the ___ and ___.
- red nucleus
- thalamus
Cerebellar circuitry overview
- inputs arrive from spinal cord and brainstem via the ICP and MCP (mostly) and project to the cortex
- cortex interprets data and sends info to deep nuclei
- deep nuclei send projections (mostly SCP) to other parts of the brain
What are the layers of the cerebellar cortex?
- top: molecular layer
- Purkinje cell layer
- granule layer
The ___ layer contains Purkinje cell dendrites granule neuron axons
molecular layer
The ___ are the only axons to leave cerebellar cortex.
purkinje
Which cerebellar nuclei contributes most of the fibers of the SCP
Dendate
