Question

Pituicytes are under the control of
A. Adenohypophysis
B. Hypothalamus
C. Neurohypophysis
D. Both (a) and (c)

Answer 1

Hint:-The pituitary gland is pea – size gland it is situated at the base of the brain just below the hypothalamus. Pituitary gland plays an important role to regulate the vital function of the body, this gland also referred as the master gland of the body because this gland operates other glands and their functions.

 Complete step-by-step solution:-
Pituicytes are special type of glial cells that found in the posterior lobe (Neurohypophysis)of pituitary gland or master gland, these cells release neurohypophysial hormones and the secretion of hormones controls by the hypothalamus. Hypothalamus is a part of the forebrain, many hormones of the pituitary gland are synthesized by hypothalamus and it regulates the secretion of these hormones. Posterior lobe of the pituitary gland is Neurohypophysis. Neurohypophysis produces substances called arginine vasopressin with antidiuretic and oxytocin which stimulate smoothness in the muscle of the mammary gland and also smooth the muscle of the uterus during birth.
Anterior pituitary also referred to as adenohypophysis or pars anterior, is a vital organ of the endocrine system. Adenohypophysis is further divided into the anterior lobe and intermediate lobe
Answer- As per the above discussion the correct answer of this question is option C, Hypothalamus, I hope you guys will make sure why the rest of options are incorrect.

Additional Information: Endocrine system controls and co – ordinate the whole body systems by secreting hormones, these hormones are secreted by special organs called endocrine gland. Glands of the endocrine system are pineal gland, pituitary gland, thyroid gland, parathyroid gland, adrenal gland, pancreas, ovaries and testes.

Note:- Hypothalamus is located at the base of diencephalon and considered as a neuroendocrine structure rather than a true endocrine gland. Its secretion is called neurohormone. The neurohormones are thyrotropin – releasing hormone, gonadotropin – releasing hormone, corticotropin, Dopamine, etc.
