Second Largest Portion of the Brain "Cerebellum"

Three myelinated bundles of meat fibers called cerebellar peduncles form communication pathways between the cerebellum and early(a) part of the CNS. The superior cerebellar peduncles connect the cerebellum to the midbrain; the middle cerebellar peduncles connect the cerebellum to the pons; and the inferior cerebellar peduncles connect the cerebellum with the bulb oblongata and spinal cord.

The function of the cerebellum is push back coordination, and it coordinates the subconscious contractions of skeletal brawn necessary for coordination, balance, and posture (Applegate, 2000, 169). The cerebellum is responsible for the coordination of skeletal muscle to invoke smooth muscle movements, and maintaining the muscle tone necessary for posture. The cerebellum re

The cerebellum is immature at birth, but develops by childhood and adolescence, and reaches its full structural growth between the fifteenth and the 20th years (Leiner and Leiner, 2002).

It contains more cells than the rest of the brain combined, and is a more rapidly acting mechanism than any other part of the brain. It receives approximately 40 million nerve fibers from the rational cortex. All information reaching the cerebellum seems to do so in the same way, regardless of the source of the information (sensory, motor, mental). Experimental indicate shows that the cerebellum is involved in the process by which novel motor tasks can be performed automatically after some practice. It is as well as involved in the mental rehearsal of motor tasks.
