Endocrine and Exocrine Glands

The secretion of this gland is more serous in dogs and more mucous in bulls. It serves to promote the movement of spermatozoa in all the mammals and to form a vaginal plug.

Von Ebner glands are glands found in a trough circling the circumvallate papillae on the dorsal surface of the tongue near the sulcus terminalis. They secrete a purely serous fluid that begins lipid hydrolysis.

This is the correct option. Endocrine glands are glands of the endocrine system that secrete their products, hormones directly into the blood rather than through a duct.

Yes, it is the correct answer. A mammary gland is an organ in female mammals that produces milk to feed young offspring. Mammals get their name from the word mammary. In humans, the mammary glands are situated in the breasts. In ruminants such as cows, goats, and deer, the mammary glands are contained in the udders. These are exocrine glands.

This is the correct option as all the above statements are correct

The adrenal gland controls the stress hormones cortisol and epinephrine. The stress hormones act by mobilizing energy from storage to muscles, increasing heart rate, blood pressure and breathing rate and shutting down metabolic processes such as digestion, reproduction, growth and immunity.

The thyroid and parathyroid glands originate from the pharyngeal pouches during embryonic development. Specifically, the thyroid develops from the floor of the pharynx (foramen cecum), while the parathyroid glands develop from the third and fourth pharyngeal pouches. 'Gills' are respiratory structures in aquatic organisms, and 'oesophageal pouch' is not the correct embryological origin.

Goiter is the abnormal enlargement of the thyroid gland caused by iodine deficiency, which leads to insufficient thyroid hormone production. The thyroid gland attempts to compensate by growing larger. The adrenal cortex, adrenal medulla, and pituitary gland are not affected by goiter.

The liver is the largest internal organ and largest gland in the human body, weighing approximately 1.5 kg. The thyroid is much smaller, while the pancreas and spleen are also considerably smaller than the liver.

A condition in which enlarged mammary glands are present in the male is called Gynaecomastia.

Endocrine glands lack ducts and release hormones directly into capillaries - which are venous microvessels. From there, hormones enter general circulation via veins. Arterial blood carries hormones away from heart to tissues, but glands don't secrete into arteries directly.

Mikulicz disease is characterised by the abnormal enlargement of the salivary and lacrimal glands.

Rabbits possess four types of salivary glands: parotid, submandibular, sublingual, and buccal (or zygomatic) glands. These glands produce saliva containing enzymes like amylase that begin the digestive process. The number four is the correct anatomical count.
