Question #2
Consider statements about human anatomy: 1. The femur is the longest bone in the body. 2. The stapes is the smallest bone in the body. 3. The hyoid bone is attached to another bone by a joint. Which are correct?
A. 1 and 2 only
B. 2 and 3 only
C. 1 and 3 only
D. 1, 2 and 3

Correct Answer: Option A


Explanation:
The femur (thigh bone) is the longest, heaviest, and strongest bone in the human skeleton. The stapes (stirrup) is a small bone in the middle ear and is the smallest bone in the human body. The hyoid bone is a U-shaped bone in the neck that supports the tongue; it is unique because it is not articulated (jointed) with any other bone, but is suspended by muscles and ligaments. Thus, statements 1 and 2 are correct.

Question #3
The gap between two neurons across which nerve impulses pass is called:
A. Soma
B. Synapse
C. Axon
D. Dendrite

Correct Answer: Option B


Explanation:
A synapse is the junction between two neurons (or neuron and effector) where the nerve impulse is transmitted from the presynaptic neuron to the postsynaptic neuron, usually via neurotransmitters. Axon carries impulses away from the cell body, dendrites receive signals, soma is the cell body. Synaptic transmission can be chemical or electrical.
