Question 3

Which type of intercellular junction in epithelial tissue allows for rapid communication and the passage of ions between cells, such as in cardiac muscle?

Accepted Answer

Gap junctions

Question 4

Which of the following equations correctly represents the relationship between tissue organization in the body?

Accepted Answer

$$Cells \rightarrow Tissues \rightarrow Organs \rightarrow Organ Systems$$

Question 5

A biopsy reveals a single layer of flat cells lining the alveoli of the lungs. What type of epithelial tissue is this?

Accepted Answer

Simple squamous epithelium

Question 6

Which connective tissue cell type is primarily responsible for secreting the extracellular matrix?

Accepted Answer

Question 7

A gland that releases its product by exocytosis without losing any part of the cell is classified as which type of gland?

Accepted Answer

Merocrine gland

Question 8

Which of the following is a function shared by all types of connective tissue?

Accepted Answer

Providing physical protection and supporting delicate organs

Question 9

A patient with a genetic defect in collagen synthesis would most likely have problems with which type of connective tissue fiber?

Accepted Answer

Collagen fibers

Question 10

Which tissue membrane lines body cavities that do NOT open to the exterior and reduces friction between organs?

Accepted Answer

Serous membrane

Question 11

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

Accepted Answer

Chondrocytes produce antiangiogenesis factor, preventing blood vessel formation

Question 12

During inflammation, which cell type releases histamine and heparin to promote vasodilation and increase blood flow to injured tissue?

Accepted Answer

Mast cell

Question 13

Which of the following equations best represents the process of tissue repair after injury?

Accepted Answer

$$Inflammation \rightarrow Regeneration \rightarrow Restoration of Function$$

Question 14

Which type of epithelial tissue is best suited for protection against mechanical stress and is found in the skin?

Accepted Answer

Stratified squamous epithelium

Question 15

A patient with chronic liver disease shows extensive fibrosis. What does this indicate about the tissue repair process in the liver?

Accepted Answer

Damaged cells are replaced by fibroblasts and collagen, leading to scar tissue

Question 16

Which of the following is a correct description of the cutaneous membrane?

Accepted Answer

Covers the body surface and is relatively waterproof and dry

Question 17

Which connective tissue type is characterized by a rigid matrix due to calcium salts and collagen fibers, and contains cells in lacunae arranged around a central canal?

Accepted Answer

Bone

Question 18

Which of the following best describes the function of goblet cells in epithelial tissue?

Accepted Answer

Produce mucin that mixes with water to form mucus

Question 19

Which type of connective tissue fiber allows tissues to return to their original length after stretching, such as in elastic ligaments?

Accepted Answer

Elastic fibers

Question 20

Which of the following best explains why the effectiveness of tissue regeneration decreases with age?

Accepted Answer

Decreased rate of repair and maintenance activities, leading to structural changes
