Difference between Cerebellum and Medulla oblongata

Cerebellum vs. Medulla oblongata

The cerebellum (cerebella or cerebellums; Latin for "little brain") is a major feature of the hindbrain of all vertebrates. The medulla oblongata or simply medulla is a long stem-like structure which makes up the lower part of the brainstem.

Brain

The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals.

Grey matter

Grey matter, or brain matter in American English, is a major component of the central nervous system, consisting of neuronal cell bodies, neuropil (dendrites and unmyelinated axons), glial cells (astrocytes and oligodendrocytes), synapses, and capillaries.

Hindbrain

The hindbrain, rhombencephalon (shaped like a rhombus) or lower brain is a developmental categorization of portions of the central nervous system in vertebrates.

Inferior cerebellar peduncle

The upper part of the posterior district of the medulla oblongata is occupied by the inferior cerebellar peduncle, a thick rope-like strand situated between the lower part of the fourth ventricle and the roots of the glossopharyngeal and vagus nerves. Each cerebellar inferior peduncle connects the spinal cord and medulla oblongata with the cerebellum, and comprises the juxtarestiform body and restiform body. Important fibers running through the inferior cerebellar peduncle include the dorsal spinocerebellar tract and axons from the inferior olivary nucleus, among others.

Inferior olivary nucleus

The inferior olivary nucleus (ION) is a structure found in the medulla oblongata underneath the superior olivary nucleus.

Neuron

A neuron, neurone, or nerve cell is an excitable cell that fires electric signals called action potentials across a neural network in the nervous system.

Nucleus (neuroanatomy)

In neuroanatomy, a nucleus (nuclei) is a cluster of neurons in the central nervous system, located deep within the cerebral hemispheres and brainstem.

Pons

The pons (pontes; from Latin pons, "bridge", from Proto-Indo-European *pónteh₁s, “path, road”, from *pent-, “path”. Cognate with Sanskrit पन्था, pánthā-) is part of the brainstem that in humans and other mammals, lies inferior to the midbrain, superior to the medulla oblongata and anterior to the cerebellum.

Posterior inferior cerebellar artery

The posterior inferior cerebellar artery (PICA) is the largest branch of the vertebral artery.

Spinal cord

The spinal cord is a long, thin, tubular structure made up of nervous tissue that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column (backbone) of vertebrate animals.

Stroke

Stroke (also known as a cerebrovascular accident (CVA) or brain attack) is a medical condition in which poor blood flow to the brain causes cell death.

Trigeminal nerve

In neuroanatomy, the trigeminal nerve (lit. triplet nerve), also known as the fifth cranial nerve, cranial nerve V, or simply CN V, is a cranial nerve responsible for sensation in the face and motor functions such as biting and chewing; it is the most complex of the cranial nerves.

The vestibular nuclei (VN) are the cranial nuclei for the vestibular nerve located in the brainstem.
