Answers (1)

The central canal of the spinal cord and the ventricles of the brain are lined with ependymal cells, a kind of glial cell. Their apical surface is covered in a great deal of microvilli. Contrarily, the hypothalamus is a part of the brain that regulates a number of homeostatic processes, including body temperature, thirst, and hunger. As a result, the mismatched pair is an option (3). Hence, option 3 is the correct answer.

Explanation for the incorrect options :

Since ependymal cells, a type of glial cell that lines the ventricles of the brain and spinal cord, have numerous microvilli on their surface, option (1) is a matched pair. The surface area available for secretion and absorption is increased by these microvilli.

Because neurosecretory cells are specialized neurons that discharge hormones into the bloodstream, option (2) is a matched pair. As a result of their endocrine capabilities, they emit hormones that operate on target cells far from the place of release.

Option (4) is a matched pair because the hypothalamus, which is situated above and in front of the pituitary gland, contains neurosecretory cells. These cells emit hormones that control the anterior pituitary gland's activity, which in turn controls the activity of the body's other endocrine glands.
