Question 1

Which of the following best defines the difference between anatomy and physiology?

Accepted Answer

Anatomy studies the structure of body parts, while physiology studies their function.

Question 2

Arrange the following levels of organization in the human body from smallest to largest: cell, organ, tissue, organ system, molecule.

Accepted Answer

Molecule, cell, tissue, organ, organ system

Question 3

A patient is experiencing numbness in the right lower quadrant of the abdomen. Which anatomical plane would best be used to describe a cross-section at the level of the umbilicus?

Accepted Answer

Transverse plane

Question 4

Which of the following is NOT a function of the plasma membrane?

Accepted Answer

Synthesizing proteins for export

Question 5

Which of the following best describes the difference between passive and active transport across the plasma membrane?

Accepted Answer

Passive transport moves substances down their concentration gradient without energy input, while active transport requires ATP to move substances against their gradient.

Question 6

A red blood cell placed in a hypotonic solution will:

Accepted Answer

Swell and possibly burst due to water influx

Question 7

Which of the following equations correctly represents the relationship between surface area ($$A$$), volume ($$V$$), and the efficiency of diffusion in a cell?

Accepted Answer

$$\frac{A}{V}$$ decreases as cell size increases

Question 8

Which of the following is a correct example of a negative feedback mechanism in the human body?

Accepted Answer

Regulation of blood glucose by insulin

Question 9

Which of the following best describes the function of tight junctions in epithelial tissue?

Accepted Answer

They prevent the passage of substances between adjacent cells

Question 10

A biopsy reveals tissue with multiple layers of flat cells. Which type of epithelial tissue is this, and where is it most likely found?

Accepted Answer

Stratified squamous; epidermis of the skin

Question 11

Which of the following connective tissue fibers provides the greatest tensile strength to tissues such as tendons?

Accepted Answer

Collagen fibers

Question 12

A patient with a genetic defect in gap junctions would most likely experience problems in which of the following processes?

Accepted Answer

Question 13

Which of the following best describes the function of the serous membranes surrounding the heart and lungs?

Accepted Answer

They reduce friction between moving organs

Question 14

Which of the following is a characteristic of nervous tissue?

Accepted Answer

It consists of neurons and supporting glial cells

Question 15

A patient presents with a burn that affects both the epidermis and the entire dermis, but not the underlying tissue. Which degree of burn is this, and what is a likely consequence?

Accepted Answer

Third-degree burn; loss of sensation and risk of infection

Question 16

Which of the following best describes the difference between thick and thin skin?

Accepted Answer

Thick skin has a thicker stratum corneum and lacks hair follicles

Accepted Answer

They produce melanin to protect against UV radiation

Question 19

A patient is diagnosed with basal cell carcinoma. Which statement about this type of skin cancer is correct?

Accepted Answer

It originates in the stratum basale and rarely metastasizes

Question 20

Which of the following best describes the function of the hypodermis?

Accepted Answer
