Chapter 1 An Introduction to Anatomy and Physiology Review Questions Questions
Question 1 of 5
The ability of a muscle to shorten forcibly and generate a pulling force is known as:
Correct Answer: A
Rationale: Contraction enables muscles to shorten and pull, driving movement. Unlike stretching or bending, it's force generation. Nurses assess it like in cramps ensuring muscle action supports mobility and function.
Question 2 of 5
The nose is ___ to the chin.
Correct Answer: D
Rationale: The nose is superior (above) the chin in anatomical position, not anterior (A, front, though true in profile), lateral (B, side), or posterior (C, back). Superiority reflects vertical hierarchy on the face, a key anatomical distinction for precise location descriptions.
Question 3 of 5
The directional term lateral describes a structure that is:
Correct Answer: D
Rationale: Lateral means further from the midline (e.g., ears lateral to nose), not closer to attachment, farther from it, or midline. This term orients anatomy sideways, distinguishing side structures from central ones, making D correct.
Question 4 of 5
What is the scientific term for the forearm?
Correct Answer: D
Rationale: Antebrachial refers to the forearm (elbow to wrist), not brachial (A, upper arm), antecubital (B, elbow front), or acromial (C, shoulder). Anatomical terminology precisely names regions, aiding in clinical accuracy like fracture descriptions.
Question 5 of 5
The term antebrachial refers to the:
Correct Answer: C
Rationale: Antebrachial denotes the forearm, not arm (A, brachial), chest, or leg. Repeated from QBA, it reinforces anatomical precision for the elbow-to-wrist region, confirming C.
