What grey matter is composed of?

Gray matter consists primarily of neuronal cell bodies, or soma. This a spherical structure that houses the neuron’s nucleus.

What is gray matter composed of quizlet?

Gray matter is neural tissue composed primarily of nerve cell bodies and unmyelinated fibers.

What is the grey matter in the brain called?

The tissue called “gray matter” in the brain and spinal cord is also known as substantia grisea, and is made up of cell bodies.

What is an example of gray matter?

Grey Matter in the Brain and Spinal Cord Gray matter, named for its pinkish-gray color, is home to neural cell bodies, axon terminals, and dendrites, as well as all nerve synapses. This brain tissue is abundant in the cerebellum, cerebrum, and brain stem.

What is white matter composed of?

White matter is found in the deeper tissues of the brain (subcortical). It contains nerve fibers (axons), which are extensions of nerve cells (neurons). Many of these nerve fibers are surrounded by a type of sheath or covering called myelin. Myelin gives the white matter its color.

Where is gray matter found?

[1] Grey matter makes up the outer most layer of the brain. The white matter and grey matter are similar as they are both essential sections of both the brain as well as the spinal cord. [2] The grey matter gets its grey tone from a high concentration of neuronal cell bodies.

What is gray matter and white matter quizlet?

The Gray Matter is a gray-colored zone that surrounds the hollow central cavity of the CNS. A mixture of neuron cell bodies of interneurons and motor neurons and neuroglia. Synapses occurs in gray matter. The White Matter contains no neuron cell bodies but millions of axons and neuroglia.

What is the composition of the gray and white matter?

Content of gray and white matter Namely, the gray matter contains glial cells, axon tracts, neuropil (glia, dendrites, and unmyelinated axons), as well as capillary blood vessels (1). The white matter contains the glial cells responsible for the production of myelin (the oligodendrocytes) and the astrocytes (1).

What composes white matter?

What makes grey matter grey?

Grey matter (or gray matter) makes up the outermost layer of the brain and is pinkish grey in tone, hence the name grey matter. It gets its grey tone from the high concentration of neuronal cell bodies in contains. Grey matter also contains unmyelinated axons.

What is gray matter in the brain quizlet?

Gray matter is on the outer-most part of the brain and it contains cell bodies, dendrites, and unmyelinated axons. White matter is in the inner-most part of the brain, consists of myelinated axons. The spinal cord had the gray matter in the middle and the white matter on the outside, the opposite from the brain.
