Question 3

Which of the following is a function of the hypodermis as described in the study guide?

Adipose storage, insulation, and shock absorption

Question 4

A biopsy of a gland reveals that its secretions are released by exocytosis without loss of cytoplasm. Which type of exocrine secretion is this?

Accepted Answer

Merocrine

Question 5

Which of the following best explains why vitamin D synthesis is important for bone health?

Accepted Answer

Vitamin D is converted to calcitriol, which increases calcium absorption in the intestines.

Question 6

A long bone is fractured and healing begins. According to the study materials, what is the correct sequence of healing events?

Accepted Answer

Accepted Answer

Parathyroid hormone (PTH)

Question 8

A tissue sample from the trachea shows ciliated cells that appear layered but all touch the basement membrane. What type of epithelium is this?

Accepted Answer

Pseudostratified columnar epithelium

Question 9

Which of the following connective tissues is specialized for energy storage and insulation?

Accepted Answer

Adipose connective tissue

Question 10

A patient with a genetic defect in desmosomes would most likely experience which of the following symptoms?

Accepted Answer

Reduced resistance to mechanical stress in tissues

Question 11

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

Accepted Answer

Compact bone is dense and provides strength; spongy bone is trabecular and houses marrow.
