Question 1

Which of the following best describes the function of osteoclasts in bone tissue?

Accepted Answer

Osteoclasts are responsible for bone resorption, breaking down bone tissue.

Question 2

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

Accepted Answer

Simple squamous epithelium

Question 3

A patient presents with a burn that damages both the epidermis and the entire dermis, but not the underlying hypodermis. Which type of burn is this?

Accepted Answer

Third-degree burn

Question 4

Which connective tissue cell type is primarily responsible for producing collagen fibers?

Accepted Answer

Fibroblasts

Question 5

Which layer of the epidermis is responsible for mitotic cell division and regeneration of skin cells?

Accepted Answer

Stratum basale

Question 6

Which of the following is a function of melanin in the skin?

Accepted Answer

Melanin protects underlying tissues from ultraviolet (UV) radiation.

Question 7

Which gland is classified as an exocrine gland and secretes its product into hair follicles in the skin?

Accepted Answer

Sebaceous gland

Question 8

Which of the following best describes the difference between compact bone and spongy bone?

Accepted Answer

Compact bone is dense and forms the outer layer of bones, while spongy bone is porous and found inside bones.

Question 9

Which of the following structures is NOT part of the axial skeleton?

Accepted Answer

Pelvic girdle

Question 10

A deficiency in which cell type would most directly impair the synthesis of the extracellular matrix in bone?

Accepted Answer

Osteoblasts

Question 11

Which of the following best describes the action of parathyroid hormone (PTH) on bone tissue?

Accepted Answer

PTH stimulates osteoclasts to increase bone resorption, raising blood calcium levels.

Question 12

Which of the following is a function of the extracellular matrix in connective tissue?

Accepted Answer

It provides structural support and mediates cell signaling.

Question 13

Which of the following best describes the process of intramembranous ossification?

Accepted Answer

Bone forms directly from mesenchymal tissue without a cartilage model.

Question 14

Which of the following cell types is most likely to be involved in the development of skin cancer?

Accepted Answer

Keratinocytes

Question 15

A patient has a mutation that impairs the function of collagen in connective tissue. Which of the following symptoms would most likely result?

Accepted Answer

Reduced tensile strength in skin and tendons

Question 16

Which of the following best describes the function of tendons?

Accepted Answer

Tendons connect muscle to bone, transmitting force for movement.

Question 17

Which of the following is the correct order of layers in the epidermis from superficial to deep?

Accepted Answer

Stratum corneum, stratum granulosum, stratum spinosum, stratum basale

Question 18

Which of the following is a function of the arrector pili muscle?

Accepted Answer

Contracts to cause hair to stand upright (goosebumps)

Question 19

Which of the following best describes the role of the periosteum in bone?

Accepted Answer

It covers the outer surface of bone and contains cells for bone growth and repair.

Question 20
