Mammalian Biology and Anatomy

The burrow of rabbit is called as warren.

Mucin is a mixture of proteins.

Large intestine is divided into rectum and colon which are long, hollow tubes that run from the stomach to the anal opening.

It is the roof of the mouth in humans and other mammals. It separates the oral cavity from the nasal cavity.

A diastema is a space or gap between two teeth. It appears most often between the two upper front teeth.

Mammary glands are modified sebaceous glands which secrete milk and are found only in mammals.

Sweat glands are absent in the rat.

True vocal cords are the lower pair of vocal cords, the edges of which can be made to tense and relax by the passage of air from the lungs, thus producing vocal sound. These are absent in hippopotamus.

They make up to 20% of the human islet cells synthesising and secreting the peptide hormone glucagon, which elevates the glucose levels in the blood.

The contraction of melanophores is regulated by melatonin.

It is the sustained muscular contraction resulting from the lesser concentration of calcium due to the removal of parathyroid gland.

The mitral valve (also called the bicuspid valve) separates the upper left heart chamber from the lower left heart chamber, i.e left auricle from left ventricle.

It is a feature of the human neck. It is the lump or protrusion that is formed by the angle of the thyroid cartilage surrounding the larynx.

The renal pelvis or pyelum is the funnel-like dilated proximal part of the ureter in the kidney.

Anti diuretic hormone is secreted by posterior pituitary. It controls the volume of water or urine in the body.
