Question

Arbor vitae is mainly composed of
A. Grey matter
B. Neuroglial cells
C. White cells
D. None of the above.

Answer 1

Hint:Arbor vitae is a Latin word that stands for “tree of life”. It is the cerebral white matter that appears like a branch of a tree. In structure, it resembles a fern. It is present in the cerebellar hemispheres.

Complete answer:
The central nervous system utilizes two main types of matter for the transmission of nerve impulses. They are grey matter and white matter. White matter works with the central nervous system that sends a signal between different parts of the body. Whereas the Gray matter will process the information from the central nervous system.
The Arbor vitae is present in the centre of the cerebellum that provides sensory information to the brain. The cerebellum along with the Arbor vitae is involved in the coordination of actions between arms and legs and also the actions that require eye and hand coordination. The cerebellum function is to connect with the other organs of the body and the work of Arbor vitae is to provide necessary sensory and motor inputs to act.
The structure of Arbor vitae consists of myelinated axons that help in the transmission of the nerve impulses throughout the body. Myelinated axons are made up of fatty acids and proteins that help in the transmission of signals along the branches of the Arbor vitae at a faster rate.
Grey matter- It is the major component of the central nervous system. It is mainly composed of neuronal cells, neuropil, glial cells, synapsis, capillaries. They are called so because they are not surrounded by white myelin that gives a natural grey colour because of the presence of neurons and glial cells.
neuroglial cells- They are the non- neuronal cells in the central nervous system and peripheral nervous system. They maintain homeostasis and protect the neurons.
White matter- It is the tissue through which the message is passed between the different areas of the grey matter. The white matter is white because of the presence of fatty substances that are surrounding the axons.
Arbor vitae is mainly composed of white cells.
Thus the correct answer is option C.

Note:
Arborvitae can be damaged by pathogens that can affect the overall functions of the brain. If it gets damaged then it will affect the coordination in the body.
