Question 1

Ashley is examining two microscope slides: one from the esophagus and one from the small intestine. Which of the following features would BEST help her distinguish the esophageal epithelium from the small intestine epithelium?

Accepted Answer

The presence of villi and microvilli in the small intestine epithelium.

Question 2

Which of the following best describes the function of the stratified squamous epithelium lining the esophagus?

Accepted Answer

Protection against abrasion from food particles.

Question 3

Scratching an itch caused by a scratchy label on your shirt is an example of a negative feedback loop. Which of the following best explains why?

Accepted Answer

Scratching removes the stimulus (itch), reducing the sensation and restoring homeostasis.

Question 4

Pleurisy involves inflammation of the serous membranes of the lungs. What are the names of these two membranes, and what does each line?

Accepted Answer

Visceral pleura lines the lungs; parietal pleura lines the thoracic cavity.

Question 5

If excess serous fluid accumulates between the pleural membranes due to pleurisy, what is the most likely effect on lung function?

Accepted Answer

It may compress the lungs, making breathing more difficult.

Question 6

Josue is having surgery on his lower back. The surgeon plans to make a cut along a plane that divides the body into superior and inferior parts. Which anatomical plane is being used?

Accepted Answer

Transverse (horizontal) plane

Question 7

A transverse (horizontal) section divides the body into which of the following?

Accepted Answer

Superior and inferior parts

Question 8

Jami is scheduled for surgery on her right tarsal region. Where on her body will the incision be made?

Accepted Answer

On her right ankle

Question 9

During Jami's tarsal surgery, the incision will be made deep to the skin but superficial to the muscle and bone. Which layers will be cut?

Accepted Answer

Skin, subcutaneous tissue, and possibly superficial fascia

Question 10

Which of the following best describes the anatomical position?

Accepted Answer

Standing upright, facing forward, arms at sides, palms facing forward, feet together

Question 11

Why is the anatomical position important in anatomy?

Accepted Answer

It provides a standard reference for describing locations and directions on the body.

Question 12

Instead of using 'superior' and 'inferior' to describe positions on the upper and lower limbs, which directional terms are used, and what do they mean?

Accepted Answer

'Proximal' (closer to the trunk) and 'distal' (farther from the trunk)

Question 13

Which of the following best summarizes the principle of complementarity of structure and function?

Accepted Answer

The structure of a body part determines its function, and vice versa.

Question 14

Which of the following is a specific example of the principle of complementarity of structure and function?

Accepted Answer

The thin walls of alveoli in the lungs allow for efficient gas exchange.

Question 15

Why does bone heal faster than cartilage after an injury?

Accepted Answer

Bone has a better blood supply than cartilage, allowing for faster delivery of nutrients and cells needed for repair.

Question 16

Which of the following best explains why a sprain (ligament injury) is often worse than a bone fracture?

Accepted Answer

Ligaments have a poor blood supply, so they heal slowly compared to bone.

Question 17

Which of the following is a likely outcome of cartilage injury?

Accepted Answer

Slow healing due to limited blood supply

Question 18

Which of the following features would help you visually distinguish skeletal muscle tissue from cardiac and smooth muscle tissue under a microscope?

Accepted Answer

Skeletal muscle cells are striated and multinucleated.

Question 19

Which structural characteristic is unique to cardiac muscle tissue?

Accepted Answer

Presence of intercalated discs connecting branched cells
