Endocrine and Exocrine Glands

Thymus gland is located behind the sternum and between the lungs.

Hypothalamus secretes PRH.

Thymus is said to be responsible for myasthenia gravis. It is believed that the thymus gland may give incorrect instructions to developing immune cells, ultimately resulting in autoimmunity and the production of the acetylcholine receptor antibodies, thereby setting the stage for the attack on neuromuscular transmission.

Parotid gland is the largest of the salivary glands.

Pancreas is an endocrine gland. Islets of Langerhans in the pancreas are endocrine in nature and secrete the hormones insulin and glucagon. The exocrine part secretes digestive enzymes. 

Pineal gland disappears at the age of 7 and in adults it is largely a fibrous tissue, so pineal gland is not present in adults.

Isthmus joins the two lobes of the thyroid gland.

Thyroid gland is the largest purely  endocrine gland in the body. Pancreas is the largest heterocrine gland.

Yes, it is correct. The secretion of this gland lubricates the urethra before ejaculation and neutralizes the acidic traces of urine in the urethra by Cowper's in males and Bartholin's in females.

This is the correct answer.

Intermediate lobe of pituitary secretes melanocyte stimulating hormone.

This is the correct answer.

The mucus has a protective effect and helps filter inspired particles. Mucus production can be greatly increased in rhinitis.

Thyroid is a butterfly-shaped gland in the lower front part of the neck. It controls metabolism and keeps the functioning of whole body properly. The thyroid gland controls how quickly the body uses energy, makes proteins, and controls how sensitive the body is to other hormones. Adrenal glands, also known as suprarenal glands, are triangular-shaped glands located on top of each kidney. They are chiefly responsible for releasing hormones in response to stress through the synthesis of corticosteroids such as cortisol and catecholamines such as epinephrine. The adrenal glands affect the functioning of kidney through the secretion of aldosterone, a hormone involved in regulating the osmolarity of blood plasma. Pituitary gland is master endocrine gland in vertebrate animals. The hormones secreted by the pituitary stimulate and control the functioning of almost all the other endocrine glands in the body. Pituitary hormones also promote growth and control the water balance of the body. The pineal gland is a small endocrine gland in the vertebrate brain. It produces the serotonin derivative melatonin, a hormone that affects the modulation of wake/sleep patterns and seasonal functions.

Parathyroid glands are four small glands, which regulate the calcium and phosphate levels in blood. The parathyroid glands are four tiny glands, located in the neck, which control the body's calcium levels. Each gland is about the size of a grain of rice (weighs approximately 30 milligrams and is 3-4 millimetres in diameter).
