Question 1

Which of the following is NOT a characteristic of epithelial tissue?

Accepted Answer

It is avascular but innervated, relying on diffusion for nutrients.

Question 2

A patient presents with a skin injury that heals rapidly. Which property of epithelial tissue best explains this observation?

Accepted Answer

High regenerative capacity due to frequent cell division.

Question 3

Which type of epithelial tissue is most suited for rapid diffusion and is found lining the alveoli of the lungs?

Accepted Answer

Simple squamous epithelium

Question 4

Which formula correctly represents the relationship between the number of cell layers ($$n) $$and the classification of epithelial tissue?

Accepted Answer

$$n = 1$$ \rightarrow$$ simple epithelium; n$$ \geq 2$$ \rightarrow$$ stratified epithelium

Question 5

Which of the following best describes the function of goblet cells in pseudostratified columnar epithelium?

Accepted Answer

Secretion of mucus to trap particles and lubricate surfaces

Question 6

A biopsy from the urinary bladder reveals cells that change shape when stretched. Which type of epithelium is present?

Accepted Answer

Transitional epithelium

Question 7

Which connective tissue type is most abundant and widely distributed in the body, serving as a packing material between other tissues?

Accepted Answer

Areolar connective tissue

Question 8

Which of the following is a correct description of the ground substance in connective tissue?

Accepted Answer

It is a gel-like material containing interstitial fluid, cell adhesion proteins, and proteoglycans.

Question 9

A ligament is able to stretch and recoil due to the presence of which type of fiber?

Accepted Answer

Elastic fibers

Question 10

Which cell type is responsible for secreting the extracellular matrix in cartilage?

Accepted Answer

Chondroblasts

Question 11

A patient with a ruptured tendon is slow to heal. Which property of dense regular connective tissue explains this?

Accepted Answer

Poor vascularization and limited ground substance

Question 12

Which connective tissue type is specialized for energy storage, insulation, and shock absorption?

Accepted Answer

Adipose tissue

Question 13

Which of the following equations best represents the relationship between the volume of water trapped in ground substance ($$V_w) $$and the viscosity ($$\eta) of $$connective tissue?

Accepted Answer

$$\eta \propto \frac{1}{V_w}$$

Question 14

Which type of cartilage is found at the tips of long bones and in the trachea, and is described as 'glassy' in appearance?

Accepted Answer

Hyaline cartilage

Question 15

Which connective tissue type forms the mesh-like stroma that supports blood cells in lymph nodes and the spleen?

Accepted Answer

Reticular connective tissue

Question 16

Which of the following best describes the function of the basement membrane in epithelial tissue?

Accepted Answer

It supports and anchors the epithelium to underlying connective tissue.

Question 17

Which type of gland releases its secretions directly into the bloodstream without the use of ducts?

Accepted Answer

Endocrine gland

Question 18

A multicellular exocrine gland that releases its product by exocytosis is classified as which type?

Accepted Answer

Merocrine

Question 19

Which connective tissue type is best suited to resist both compression and tension, and is involved in mineral storage and hematopoiesis?

Accepted Answer

Bone

Question 20

A patient with a genetic defect in collagen synthesis would most likely have problems with which tissue function?

Accepted Answer

High tensile strength and resistance to stretching in connective tissues
