Question 1

Which of the following best describes the main function of epithelial tissue in the human body?

Accepted Answer

It covers body surfaces, lines internal surfaces, and serves essential protective and secretory functions.

Question 2

A gland that releases its secretions directly into the bloodstream without the use of ducts is classified as which type of gland?

Accepted Answer

Endocrine gland

Question 3

Which type of secretion involves the release of products by exocytosis from secretory vesicles at the apical surface of the gland cell?

Accepted Answer

Merocrine secretion

Question 4

A patient has a genetic disorder affecting the production of collagen fibers. Which tissue type would be most directly impacted by this condition?

Accepted Answer

Connective tissue

Question 5

Which connective tissue cell type is primarily responsible for producing extracellular matrix components such as collagen?

Accepted Answer

Fibroblasts

Question 6

Which of the following is a correct description of dense regular connective tissue?

Accepted Answer

It consists of tightly packed, parallel collagen fibers and is found in tendons and ligaments.

Question 7

Which type of cartilage is most common in the body and reduces friction between bones at synovial joints?

Accepted Answer

Hyaline cartilage

Question 8

A newborn is found to have a higher proportion of brown fat compared to an adult. What is the primary function of brown fat in infants?

Accepted Answer

Rapid heat production through lipid breakdown

Question 9

Which of the following best explains why cartilage heals slowly after injury?

Accepted Answer

Chondrocytes produce antiangiogenesis factor, making cartilage avascular.

Question 10

Which connective tissue fiber type is most abundant in tendons and ligaments and resists force in one direction?

Accepted Answer

Collagen fibers

Question 11

A patient presents with swelling and redness after a tissue injury. Which two processes are involved in the tissue's response to injury?

Accepted Answer

Inflammation and regeneration

Question 12

Which of the following is a function of neuroglia in nervous tissue?

Accepted Answer

Supporting and protecting neurons

Question 13

Which muscle tissue type is striated, involuntary, and found only in the heart?

Accepted Answer

Cardiac muscle

Question 14

Which of the following best describes the role of microvilli on epithelial cells lining the small intestine?

Accepted Answer

They increase the surface area for absorption.

Question 15

Which of the following equations correctly represents the calculation of total surface area ($$A) of $$microvilli on a cell, given $$n$$ microvilli each with surface area $$a$$?

Accepted Answer

$$A = n 	imes a$$

Question 16

A patient with a deficiency in mast cells would most likely have impaired function in which process?

Accepted Answer

Inflammatory response

Question 17

Which of the following best describes the difference between simple and compound exocrine glands?

Accepted Answer

Simple glands have undivided ducts, while compound glands have divided ducts.

Question 18

Which supporting connective tissue is calcified and contains osteocytes arranged around central canals?

Accepted Answer

Bone (osseous tissue)

Question 19

Which of the following is a correct sequence of events in holocrine secretion?

Accepted Answer

Cells burst, releasing their contents and dying; stem cells replace lost cells.

Question 20

Which of the following best explains why tissue regeneration decreases and cancer rates increase with advancing age?

Accepted Answer

Stem cell activity and tissue repair slow down, while mutations accumulate over time.
