Question 2

A tissue sample from the lining of the small intestine shows tall, column-shaped cells with microvilli on their apical surface. What type of epithelial tissue is this?

Accepted Answer

Simple columnar epithelium

Question 3

Which connective tissue type is characterized by a gel-like ground substance, avascularity, and cells called chondrocytes located in lacunae?

Accepted Answer

Cartilage

Question 4

A patient suffers a deep skin wound. Which connective tissue type is most responsible for binding the epithelial tissue to deeper structures and facilitating healing?

Accepted Answer

Loose areolar connective tissue

Question 5

Which of the following is a property that distinguishes skeletal muscle tissue from cardiac and smooth muscle tissue?

Accepted Answer

It is striated and under voluntary control

Question 6

Which type of membrane lines body tracts that are open to the exterior environment and may include absorptive and ciliated cells?

Accepted Answer

Mucous membrane

Question 7

A histology slide shows parallel bundles of collagen fibers with fibroblasts compressed between them and very little ground substance. Which tissue is this most likely to be?

Accepted Answer

Dense regular connective tissue

Question 8

Which of the following cell types is primarily responsible for producing fibers and ground substance in connective tissue?

Accepted Answer

Fibroblasts

Question 9

Which tissue type is specialized for rapid transmission of information to other cells?

Accepted Answer

Nervous tissue

Question 10

A biopsy from the trachea reveals cells of varying heights, all touching the basement membrane, with cilia on the apical surface. What is the most likely tissue type?

Accepted Answer

Pseudostratified ciliated columnar epithelium

Question 11

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

Accepted Answer

It is avascular and relies on diffusion for nutrient supply

Question 12

Which type of connective tissue is found in lymph nodes, spleen, thymus, and bone marrow, and is characterized by a network of reticular fibers?

Accepted Answer

Reticular connective tissue

Question 13

Which of the following is a function of adipose tissue?

Accepted Answer

Anchoring and cushioning organs

Question 14

Which type of cartilage is found in the external ear and epiglottis, and provides flexible, elastic support?

Accepted Answer

Elastic cartilage

Question 15

Which of the following best describes the extracellular matrix of connective tissue?

Accepted Answer

It consists of ground substance and fibers, and is often greater in volume than the cells

Question 16

Which type of muscle tissue is found in the walls of hollow organs such as the stomach and intestines, and is not striated?

Accepted Answer

Smooth muscle

Question 17

A histology slide shows bone cells (osteocytes) occupying lacunae between concentric layers (lamellae) of calcified matrix. Which tissue is this?

Accepted Answer

Bone (osseous tissue)

Question 18

Which of the following equations correctly represents the relationship between cell volume ($$V) $$and surface area ($$A) $$for a spherical cell, and explains why simple squamous epithelium is efficient for diffusion?

Accepted Answer

$$A = 4 \pi r^2$, \quad V = \frac{4}{3} \pi r^3$

Question 19

Which of the following best explains the role of intercalated discs in cardiac muscle tissue?

Accepted Answer

They provide rapid transmission of electrical signals and strong mechanical attachment between cells

Question 20

A patient has a disorder affecting the basement membrane of epithelial tissue. Which of the following consequences is most likely?

Accepted Answer

Reduced support and attachment of epithelial cells to underlying connective tissue
