Question

Herring bodies are found in
A. Adenohypophysis
B. Neurohypophysis
C. Thyroid
D. Adrenal medulla

Answer 1

Hint: Herring bodies are the part of neurons .These are mainly present at the terminal portion of axons pituitary is divided mainly into two parts that are Adenohypophysis and neurohypophysis. Neurohypophysis stores hormones of hypothalamus gland.

Complete step by step answer: Herring bodies also known as neurosecretory bodies are the structure found in the posterior pituitary. Structure of herring bodies was first described by Percy Theodore in 1908. Hormones are temporarily stored in these locations. They also represent the terminal end of axons from the hypothalamus.
Hormones like ADH that are Antidiuretic hormone and oxytocin both are stored in herring bodies but not simultaneously. Only one type of hormone is stored in one herring body.
Herring body also contains a type of neurophysin and ATP. Neurophysin are of two types: Neurophysin I and Neurophysin II which bind to oxytocin and ADH. They form single complex proteins and are stored in neurophysin.
Thyroid gland secretes thyroxine hormone and regulates the intake of iodine. Deficiency of thyroxine may cause goiter disease.
Adrenal gland present above the kidney is known as an emergency gland. Adrenaline hormone is secreted by adrenal gland which regulates the processes of the body during stressful conditions.
From the above discussion, we have concluded that herring bodies are found in neurohypophysis.
So, the correct answer is option B that is neurohypophysis.

Note: Approximately 1, 00,000 axons participate in the process of secretion of oxytocin ADH from neurons to form posterior pituitary or neurohypophysis. Neurohypophysis also contains glial cells and other pituicytes (poorly defined cells). Antidiuretic hormone acts on the kidney while oxytocin acts on the uterus.
