Question 3 of 5
Which gland is often abnormal in patients with myasthenia gravis?
Correct Answer: A

Question 4 of 5
In which structure do sperm mature after they are produced?
Correct Answer: B
Rationale: The epididymis is the correct answer because it is the coiled tube where sperm mature and gain motility after being produced in the testes. This maturation process is essential for sperm to become capable of fertilizing an egg. The epididymis also stores sperm until they are ejaculated during sexual activity.
Question 5 of 5
A microscopic gap between a pair of adjacent neurons over which nerve impulses pass when going from one neuron to the next is called:
Correct Answer: B
Rationale: Synapse is the correct answer because it is the junction between two neurons where electrical or chemical signals are transmitted. Neurotransmitters are the chemicals that facilitate this transmission, but the gap itself is called the synapse.
