Question

Match the items given in column A with the most appropriate ones in column B and rewrite the correct matching pairs.

Column 1	Column 2
Sacculus	Pituitary Gland
Hypothalamus	Dynamic Equilibrium
Afferent nerve	Static body balance
Utricle	Transmits impulses from receptor organs to the spinal cord.

Answer 1

(A)

Sacculus - II. Dynamic Equilibrium

1. Saculus is a part of the inner ear that, along with the utricle, is responsible for maintaining body balance.
2. Dynamic equilibrium means the equilibrium of the body while in motion. If the body is not balanced, you may fall.
3. The function of the saccule is to orient the body in space while in movement (like walking) or dynamic equilibrium.

(B) Hypothalamus - I. pituitary gland

1. Hypothalamus is one of the major glands in your brain that controls your hormones.
2. The pituitary gland is a tiny bean pea-like gland situated below the hypothalamus.
3. The hypothalamus plays a very important role in the secretion of hormones.
4. The hypothalamus secretes releasing hormones and inhibiting hormones which will either stimulate or inhibit the production of hormones in the pituitary gland.

(C) Afferent nerve - II. Transmits impulses from the receptor organ to the spinal cord

1. Afferent nerves are the sensory nerves that provide a link to the brain or spinal cord and the sensory organ or muscle etc.
2. The function of the afferent nerve is to collect the information or stimulus from the surroundings and send it to the spinal cord or the brain.
3. It transmits the electrical stimulus or impulses from the receptor organ to the spinal cord.

(D) Utricle - III. Static body balance

1. The utricle, along with the saccule, is responsible for the balance of the body.
2. The utricle provides stability to the body when it's still or, in other words, when you are holding a position, it provides the control to hold that position.
3. The utricle provides postural stability, which means static balance.
4. Hence the utricle is responsible for static body balance.

Final answer:

Column A	Column B
Sacculus	II. Dynamic Equilibrium
Hypothalamus	I. Pituitary Gland
Afferent nerve	IV. Transmits impulses from receptor organs to the spinal cord.
Utricle	III. Static body balance
