Answer:
The correct answer is "grey; central canal".
Explanation:
Grey matter refers to an area of the brain, brainstem and cerebellum comprised of unmyelinated neurons and other cells that has given its name for having a pinkish-grey color in the living brain. Grey matter is also present in the spinal cord in an are of three grey columns that are H-shaped and it is located around the central canal filled with cerebrospinal fluid
The nervous and the endocrine system are tightly linked together.
The main reason for this linkage is due to the connection of the hypothalamus (nervous system) and the hypophysis (a gland in the endocrine system)
The hypophysis is the ''controller'' of all of the other endocrine glands.
The connection between the hypothalamus and the hypophysis enables the nervous system to control the hormone levels of all of the major endocrine glands in the body.
The hypothalamus releases hormones into the bloodstream that leads to the hypophysis. These hormones induce a release of hypophysis hormones that enter the bloodstream and when they reach the target gland (for example pancreas) these hormones induce the release of the hormones of that gland (in the case of the pancreas, insulin).
The hypothalamus monitors the concentration of hormones in the blood, and a high level of a certain hormone blocks the release of the hypothalamus' hormones. Therefore, a high level of insulin blocks a cascade of hormone release that starts in the hypothalamus that leads to its release in the pancreas.
Six distinct antibody subtypes can be produced in response to the antigen.
It is assumed that a certain antigen has six distinct antigenic determination sites.
To find out how many various types of antibodies this antigen can trigger production of, read on.
A molecule, chemical structure, foreign particle, pollen grain, or any other substance that can attach to a particular antibody or T-cell receptor is referred to as an antigen.
An epitope is an antigenic determinant, which is the component of an antigen that the immune system recognizes.
An antibody is a large, Y-shaped protein that the immune system employs to recognize and destroy foreign substances like dangerous germs and viruses.
