Chapter 1 An Introduction to Anatomy and Physiology Review Questions Questions
Question 1 of 5
The process of cell division that results in the formation of sperm and egg cells is called:
Correct Answer: B
Rationale: Meiosis halves genetic material to produce sperm and eggs, enabling sexual reproduction. Unlike mitosis's growth role, it ensures genetic diversity. Healthcare leverages this in fertility treatments, understanding its unique division shapes life's beginnings.
Question 2 of 5
The body's ability to maintain a stable internal environment despite external changes is known as what?
Correct Answer: A
Rationale: Homeostasis keeps internal conditions steady like pH or temperature amid external flux. Unlike evolutionary shifts, it's immediate balance. Nurses monitor it like in fever intervening to preserve stability, ensuring cells thrive under varying conditions.
Question 3 of 5
Which of the following is NOT a function of the skin?
Correct Answer: B
Rationale: Skin regulates heat, blocks germs, and senses stimuli, but hormone production belongs to endocrine glands. Nurses treat skin for its protective roles like burns not hormonal ones, distinguishing its external focus.
Question 4 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 5 of 5
Structures found within a cell that perform specific functions are:
Correct Answer: B
Rationale: Organelles are specialized structures within cells, like mitochondria producing energy, distinct from atoms (A, chemical units), organs (C, tissue groups), or tissues (D, cell groups). They're critical to cellular function, enabling anatomy to trace life processes from microscopic to macroscopic levels, making B the accurate choice.
