Cerebellar Anatomy

The folded outer layer of the cerebellum cerebellar cortex has smaller and more compact folds than those of the cerebral cortex. The cerebellum has special sensors that detect shifts in balance and movement.

The cerebellum integrates nerve impulses from the labyrinths of the ear and from positional sensors in the muscles.

Cerebellar anatomy. The cerebellum receives its blood supply from three paired arteries. Posterior inferior cerebellar artery pica. Four deep cerebellar nuclei are embedded in the white matter.

Like the cerebral cortex the cerebellum is comprised of white matter and a thin outer layer of densely folded gray matter. Anatomists classify the cerebellum as part of the metencephalon which also includes the pons and all its connections with other parts of the brain travel through the pons. The cerebellum coordinates voluntary movements such as posture balance coordination and speech resulting in smooth and balanced muscular activity.

It is also important for learning motor behaviors. The cerebellum is separated from the overlying cerebrum by a layer of leathery dura mater. The cerebellum receives information from the sensory systems the spinal cord and other parts of the brain and then regulates motor movements.

Each part of the cortex consists of the same small set of neuronal elements laid out in a highly stereotyped geometry. The subdivisions of the cerebellar vermis can be remembered by this mnemonic. The cerebellum has several functions relating to movement and coordination including.

Gross anatomy of cerebellumbr locationbr ullithe term cerebellum is from latin meaning the little brainit is a part of the hindbrain situated in the posterior cranial fossa. Cerebellumbr bybr dr manah chandra changmaibr 2. Anatomy of the brain.

Most body movements require the coordination of multiple muscle groups. Superior cerebellar artery sca. The metencephalon is the upper part of the rhombencephalon or hindbrain.

It divides into lateral and medial branches that supply the inferior portion of the. The cerebellar folia run parallel to the calvaria in an onion like configuration. The anatomy of the cerebellum can be viewed at three levels.

At the level of gross anatomy the cerebellum consists of a tightly folded layer of cortex with white matter underneath and a fluid filled ventricle at the base. Cerebellum section of the brain that coordinates sensory input with muscular responses located just below and behind the cerebral hemispheres and above the medulla oblongata. Anterior inferior cerebellar artery aica.

At the level of gross anatomy the cerebellum consists of a tightly folded and crumpled layer of cortex with white matter underneath several deep nuclei embedded in the white matter and a fluid filled ventricle in the middle. Anatomy of cerebellum 1.
