In the male reproductive system, the spermatozoa are stored and mature in the: MCQ with Answer and Explanation

In the male reproductive system, the spermatozoa are stored and mature in the:
A. Prostate gland
B. Epididymis
C. Vas deferens
D. Seminal vesicles
Answer: Option B
Solution (By JKSSB Mock Tests)
The epididymis is a coiled tube on the posterior surface of the testis where spermatozoa undergo maturation and are stored until ejaculation. Sperm acquire motility here. Seminal vesicles and prostate gland secrete seminal fluid. Vas deferens transports sperm from epididymis to ejaculatory duct. Testes produce sperm and testosterone. Sperm maturation includes gaining ability to fertilize.

Question #2
The basic structural and functional unit of the nervous system is:
A. Nephron
B. Axon
C. Neuron
D. Dendrite

Correct Answer: Option C


Explanation:
The neuron is the nerve cell, the fundamental unit of the nervous system, responsible for receiving, processing, and transmitting electrochemical signals. It consists of a cell body (soma), dendrites, and axon. Axon and dendrite are parts of a neuron. Nephron is the unit of kidney. Neurons communicate via synapses using neurotransmitters.

Question #3
Consider the following statements about the heart:
1. The SA node is the natural pacemaker.
2. The AV node delays the impulse before it passes to ventricles.
3. The Purkinje fibers conduct impulses through the ventricular walls.
Which of the above is/are correct?
A. 2 and 3 only
B. 1, 2, and 3
C. 1 and 2 only
D. 1 and 3 only

Correct Answer: Option B


Explanation:
All three are correct: SA node initiates impulse, AV node delays it to allow atrial emptying, Purkinje fibers spread impulse through ventricles.
