Introduction to Anatomy and Physiology Lesson 1.1 Study Questions Questions
Question 1 of 5
Which one of the following statements is correct?
Correct Answer: D
Rationale: The dorsal cavity houses the brain and spinal cord, a correct anatomical fact reflecting its back-side role. Nurses target this for neurological care like spinal taps unlike ventral or diaphragmatic separations. Other statements err: the diaphragm divides chest from abdomen, reproductive organs sit partly outside ventral bounds, and the spinal cord isn't abdomino-pelvic. This clarity guides precise health focus.
Question 2 of 5
A function of the endocrine system is to produce
Correct Answer: C
Rationale: The endocrine system's primary role is secreting chemical messengers that regulate bodily functions like growth and metabolism. These substances travel through the bloodstream, influencing distant tissues to maintain balance. Nurses monitor this system for disorders like thyroid imbalances where production falters, affecting overall health. Unlike immune defenses, digestive catalysts, or nerve signals, this system's output is uniquely suited to long-range coordination, distinguishing it in physiological harmony and making it a cornerstone of systemic regulation.
Question 3 of 5
The region of the body between the head and thorax is most appropriately referred to as the:
Correct Answer: D
Rationale: The cervical region is the neck, anatomically between the head and thorax (chest). The lumbar region is the lower back, throat is vague, and torso spans chest to pelvis none fit precisely. In anatomical terms, cervical vertebrae (CA-C7) define this transition, critical for nerve and vessel passage (e.g., carotid artery), making D the most appropriate term.
Question 4 of 5
The relationship between structure and function is best described as:
Correct Answer: B
Rationale: Structure determines function e.g., the heart's muscular walls (structure) enable pumping (function). Negative feedback regulates, not defines, this link. It's always relevant (C, D false). Anatomically, this principle is foundational: lung alveoli's thinness aids gas exchange, kidney tubules filter blood B captures this universal relationship.
Question 5 of 5
The foot is to the thigh as the hand is to the:
Correct Answer: A
Rationale: The foot is distal to the thigh (femur); the hand is distal to the brachium (A, upper arm), not shoulder, palm (C, hand part), or digits. Anatomically, this analogy tracks limb segments hand below elbow mirrors foot below knee making A apt.
