Question 2

The second image shows a cell with a spindle shape and a single, centrally located nucleus. Which tissue type does this cell most likely belong to?

Accepted Answer

Smooth muscle tissue

Question 3

Which of the following best describes the cell in the third image (square cell with a large, central nucleus)?

Accepted Answer

Simple cuboidal epithelial cell

Question 4

The fourth image shows a tall, rectangular cell with an oval nucleus near the base. Which tissue type is this characteristic of?

Accepted Answer

Simple columnar epithelium

Question 5

Which tissue type is represented in the fifth image (multiple layers of cells with flattened cells at the surface)?

Accepted Answer

Stratified squamous epithelium

Question 6

The sixth image shows a tall cell with microvilli on its apical surface. What is the main function of these microvilli?

Accepted Answer

Increase surface area for absorption

Question 7

The seventh image shows a tall, rectangular cell with a single, oval nucleus. Which of the following is a likely location for this cell type?

Accepted Answer

Lining of the stomach and intestines

Question 8

The eighth image shows three types of glandular secretion. Which method involves the entire cell rupturing to release its contents?

Accepted Answer

Holocrine secretion

Question 9

The ninth image shows a tissue with wavy, densely packed fibers. Which type of connective tissue is this, and what is its primary function?

Accepted Answer

Dense regular connective tissue; resists tension in one direction

Question 10

The tenth image shows concentric rings with central spaces. Which tissue is this, and what is the function of the central canal?

Accepted Answer

Compact bone; allows passage of blood vessels and nerves

Question 11

The eleventh image shows a long, cylindrical, striated cell with multiple nuclei. Which muscle tissue is this, and where is it found?

Accepted Answer

Skeletal muscle; attached to bones

Question 12

The twelfth image shows a branched, striated muscle cell with intercalated discs. What is the main function of these intercalated discs?

Accepted Answer

Allow rapid communication between cells for synchronized contraction

Question 13

Which of the following best describes the difference between epithelial and connective tissues?

Accepted Answer

Epithelial tissues have tightly packed cells with little matrix, while connective tissues have scattered cells with abundant matrix.

Question 14

A patient suffers a tendon injury. Which type of connective tissue is primarily involved, and what is its main structural protein?

Accepted Answer

Dense regular connective tissue; collagen

Question 15

Which membrane lines body cavities that open to the exterior and is involved in secretion and absorption?

Accepted Answer

Mucous membrane

Question 16

During tissue repair, which cells are responsible for restoring the original function of the tissue?

Accepted Answer

Parenchymal cells

Question 17

Which of the following best explains why cartilage heals more slowly than bone?

Accepted Answer

Cartilage is avascular, while bone is highly vascular.

Question 18

Which of the following equations best represents the composition of the connective tissue matrix?

Accepted Answer

$$	ext{Matrix} = 	ext{Fibers} + 	ext{Ground Substance}$$

Question 19

A biopsy reveals tissue with cilia and goblet cells lining the respiratory tract. Which epithelial tissue is this, and what is the function of the goblet cells?

Accepted Answer

Pseudostratified columnar epithelium; secrete mucus

Question 20

Which of the following best describes the process of fibrosis during tissue repair?

Accepted Answer

Replacement of normal tissue with scar tissue
