Difference between Cerebellum and Upper motor neuron

Cerebellum vs. Upper motor neuron

The cerebellum (Latin for "little brain") is a major feature of the hindbrain of all vertebrates. Upper motor neurons (UMNs) are the main source of voluntary movement.

Action potential

In physiology, an action potential occurs when the membrane potential of a specific axon location rapidly rises and falls: this depolarisation then causes adjacent locations to similarly depolarise.

Cerebral cortex

The cerebral cortex is the largest region of the cerebrum in the mammalian brain and plays a key role in memory, attention, perception, cognition, awareness, thought, language, and consciousness.

Fine motor skill

Fine motor skill (or dexterity) is the coordination of small muscles, in movements—usually involving the synchronization of hands and fingers—with the eyes.

Medulla oblongata

The medulla oblongata (or medulla) is located in the brainstem, anterior and partially inferior to the cerebellum.

Multiple sclerosis

Multiple sclerosis (MS) is a demyelinating disease in which the insulating covers of nerve cells in the brain and spinal cord are damaged.

Neuron

A neuron, also known as a neurone (British spelling) and nerve cell, is an electrically excitable cell that receives, processes, and transmits information through electrical and chemical signals.

Pons

The pons (Latin for "bridge") is part of the brainstem, and in humans and other bipeds lies inferior to the midbrain, superior to the medulla oblongata and anterior to the cerebellum.

Primary motor cortex

The primary motor cortex (Brodmann area 4) is a brain region that in humans is located in the dorsal portion of the frontal lobe.

Pyramidal cell

Pyramidal cells, or (pyramidal neurons), are a type of multipolar neuron found in areas of the brain including the cerebral cortex, the hippocampus, and the amygdala.

Spinal cord

The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column.
