Question 1

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

Accepted Answer

It acts as a selective filter and provides structural reinforcement, resisting stretching and tearing.

Question 2

A biopsy of a patient's trachea reveals ciliated pseudostratified columnar epithelium. What is the primary function of this tissue in the trachea?

Accepted Answer

To move mucus and trapped particles out of the respiratory tract.

Question 3

Which connective tissue type is most likely to be found in the walls of large arteries such as the aorta, and what property does it provide?

Accepted Answer

Elastic connective tissue; provides recoil and stretch.

Question 4

A patient suffers a deep skin wound. Which of the following best describes the sequence of tissue repair?

Accepted Answer

Inflammation, organization (restoring blood supply), regeneration and fibrosis.

Question 5

Which of the following statements about epithelial tissue is correct?

Accepted Answer

Epithelial tissue is avascular but innervated, receiving nutrients by diffusion from underlying connective tissue.

Question 6

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

Accepted Answer

Merocrine

Question 7

Which of the following best explains why dense regular connective tissue is well-suited for forming tendons and ligaments?

Accepted Answer

Its collagen fibers are arranged in parallel, providing high tensile strength in one direction.

Question 8

Which of the following cell types is responsible for producing the extracellular matrix in connective tissue?

Accepted Answer

Fibroblasts

Question 9

A tissue sample from the urinary bladder shows cells that can change shape and stretch. Which type of epithelium is this?

Accepted Answer

Transitional epithelium

Question 10

Which of the following best describes the function of proteoglycans in the ground substance of connective tissue?

Accepted Answer

They attract water, making the ground substance viscous and able to resist compressive forces.

Question 11

A patient with a genetic defect in collagen synthesis would most likely have problems with which of the following tissue functions?

Accepted Answer

Providing tensile strength in connective tissues.

Question 12

Which of the following is a key difference between endocrine and exocrine glands?

Accepted Answer

Endocrine glands secrete hormones directly into the bloodstream, while exocrine glands secrete their products onto body surfaces or into body cavities.

Question 13

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

Accepted Answer

Cartilage is avascular and relies on diffusion for nutrient supply, while bone is highly vascularized.

Question 14

A histological slide shows a tissue with multiple layers of flat cells at the surface and cuboidal cells at the base. What is the most likely function of this tissue?

Accepted Answer

Protection against abrasion (stratified squamous epithelium).

Question 15

Which of the following best describes the role of the basal lamina in epithelial tissue?

Accepted Answer

It acts as a selective filter and provides a surface for cell migration during wound healing.

Question 16

Which connective tissue type is most likely to be found in the dermis of the skin and why?

Accepted Answer

Dense irregular connective tissue; it provides strength in multiple directions.

Question 17

A patient with a severe burn loses the epidermis and part of the dermis. Which tissue types are primarily affected?

Accepted Answer

Stratified squamous epithelium and dense irregular connective tissue.

Question 18

Which of the following best explains why scar tissue is less flexible than normal tissue?

Accepted Answer

Scar tissue contains more collagen fibers and fewer elastic fibers than normal tissue.

Question 19

Which of the following is a function of serous membranes?

Accepted Answer

They produce serous fluid to reduce friction between organs in closed body cavities.

Question 20

Which primary germ layer gives rise to nervous tissue?

Accepted Answer

Ectoderm
