Question 1

Which of the following best describes the primary function of epithelial tissue in the human body?

Accepted Answer

It covers internal and external surfaces, forming selective barriers and providing protection.

Question 2

A patient presents with damage to the basement membrane of their epithelial tissue. Which of the following consequences is most likely to occur?

Accepted Answer

Loss of strength and increased distortion of the epithelial layer.

Question 3

Which type of epithelial tissue is best suited for areas of the body exposed to mechanical or chemical stress, such as the skin and vaginal lining?

Accepted Answer

Stratified squamous epithelium

Question 4

Which of the following is a characteristic unique to pseudostratified columnar epithelium?

Accepted Answer

All cells contact the basement membrane but nuclei are at different levels, giving a layered appearance.

Question 5

Which type of connective tissue fiber is most abundant and provides strength and resistance to stretching?

Accepted Answer

Collagen fibers

Question 6

A biopsy of a patient’s lymph node reveals a network of thin, branching fibers forming the organ’s framework. Which connective tissue fiber is most likely present?

Accepted Answer

Reticular fibers

Question 7

Which connective tissue type is found under the skin, provides cushioning, and supports epithelia?

Accepted Answer

Areolar connective tissue

Question 8

A tendon is composed primarily of which type of connective tissue?

Accepted Answer

Dense regular connective tissue

Question 9

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

Accepted Answer

Cartilage contains few cells and is avascular, limiting nutrient supply for repair.

Question 10

Which type of cartilage is found at the ends of bones in synovial joints and reduces friction?

Accepted Answer

Hyaline cartilage

Question 11

A patient with a ruptured intervertebral disc is most likely experiencing damage to which type of cartilage?

Accepted Answer

Fibrocartilage

Question 12

Which tissue membrane lines body cavities that are not open to the outside and produces a fluid to reduce friction between organs?

Accepted Answer

Serous membrane

Question 13

Which of the following is TRUE regarding the cutaneous membrane?

Accepted Answer

It is composed of stratified squamous epithelium and dense irregular connective tissue.

Question 14

Which type of muscle tissue is primarily responsible for voluntary movement?

Accepted Answer

Skeletal muscle

Question 15

Which tissue type is specialized for transmitting electrical impulses and is most concentrated in the brain and spinal cord?

Accepted Answer

Nervous tissue

Question 16

During inflammation, which of the following is NOT a typical sign or symptom?

Accepted Answer

Loss of sensation

Question 17

Which equation best represents the relationship between tissue volume ($V$), cell volume ($V_c$), and extracellular matrix volume ($V_{em}$) in connective tissue?

Accepted Answer

$V = V_c + V_{em}$

Question 18

A patient with a genetic defect in the production of elastin would most likely have problems with which tissue property?

Accepted Answer

Ability to return to original length after stretching

Question 19

Which of the following best explains why simple squamous epithelium is found lining blood vessels and air sacs of the lungs?

Accepted Answer

It allows for rapid diffusion and transport due to its thin, single layer.

Question 20

Which of the following is a correct statement about glandular epithelium?

Accepted Answer

Exocrine glands discharge secretions onto the epithelial surface, while endocrine glands release hormones into tissue fluid and blood.
