Question 1

Which of the following best describes the primary function of epithelial tissue as discussed in Chapter 4?

Accepted Answer

Epithelial tissue acts as a protective barrier, controls permeability, and is involved in secretion and absorption.

Question 2

During a practical section, students observe a slide of connective tissue. Which feature distinguishes connective tissue from epithelial tissue?

Accepted Answer

Connective tissue has abundant extracellular matrix and fewer cells compared to epithelial tissue.

Question 3

A patient suffers a burn that damages the integumentary system. Which layer is most responsible for providing waterproofing and protection against pathogens?

Accepted Answer

The epidermis

Question 4

Which equation correctly represents the relationship between muscle force ($$F$$), cross-sectional area ($$A$$), and muscle stress ($$\sigma$$)?

Accepted Answer

$$\sigma = \frac{F}{A}$$

Question 5

A histology slide shows stratified squamous epithelium. Which real-life location in the body would you expect to find this tissue?

Accepted Answer

Covering the skin surface (epidermis)

Question 6

Which of the following best explains why bone tissue is considered a connective tissue?

Accepted Answer

Bone tissue contains a mineralized extracellular matrix that provides support and protection.

Question 7

A student is asked to identify the main function of nervous tissue. Which answer is most accurate?

Accepted Answer

Nervous tissue transmits electrical signals for communication and coordination.

Question 8

During a practical exam, you are asked to distinguish between skeletal and cardiac muscle under the microscope. Which feature is unique to cardiac muscle?

Accepted Answer

Intercalated discs connecting adjacent cells

Question 9

Which formula correctly calculates the total number of bones in the adult human body, given the axial skeleton has $$80$$ bones and the appendicular skeleton has $$126$$ bones?

Accepted Answer

$$80 + 126$$

Question 10

A patient presents with muscle weakness in the anterior thigh. Which muscle group is most likely affected?

Accepted Answer

Quadriceps femoris

Question 11

Which of the following best describes the function of the reflex arc in the nervous system?

Accepted Answer

It transmits signals directly from sensory neurons to motor neurons for rapid response.

Question 12

A histology section shows dense regular connective tissue. Which anatomical structure is most likely composed of this tissue?

Accepted Answer

Tendons connecting muscle to bone

Question 13

Which equation best represents the calculation of nerve conduction velocity ($$v) $$given distance ($$d) $$and time ($$t$$)?

Accepted Answer

$$v = \frac{d}{t}$$

Question 14

A patient has difficulty flexing their forearm. Which muscle is most likely impaired?

Accepted Answer

Biceps brachii

Question 15

Which of the following is a function of the skeletal system as covered in Chapter 7?

Accepted Answer

Storage of minerals such as calcium and phosphorus

Question 16

A student is asked to explain the difference between the axial and appendicular skeleton. Which statement is correct?

Accepted Answer

The axial skeleton includes the skull, vertebral column, and thoracic cage; the appendicular skeleton includes the limbs and girdles.

Question 17

Which muscle is primarily responsible for abduction of the arm at the shoulder joint?

Accepted Answer

Deltoid

Question 18

A patient has suffered damage to the peripheral nervous system. Which function is most likely impaired?

Accepted Answer

Transmitting signals between the central nervous system and the rest of the body

Question 19

Which equation correctly represents the calculation of total muscle work ($$W) $$given force ($$F) $$and distance ($$d$$)?

Accepted Answer

$$W = F 	imes d$$

Question 20

A sheep brain dissection reveals the cerebellum. What is the primary function of the cerebellum?

Accepted Answer

Coordination of voluntary movements and balance
