Question 4

A biopsy of a patient’s gland reveals cells that release their secretions by exocytosis without losing any cytoplasm. Which type of secretion is this, and which gland is an example?

Accepted Answer

Merocrine secretion; salivary gland

Question 5

Which connective tissue fiber type is most responsible for the tensile strength of tendons?

Accepted Answer

Cartilage

Question 7

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

Accepted Answer

Accepted Answer

Mast cell

Question 10

Which of the following best describes the difference between endocrine and exocrine glands?

Accepted Answer

Endocrine glands secrete hormones into the blood; exocrine glands secrete onto epithelial surfaces through ducts

Question 11

Which tissue type is most likely to regenerate well after injury?

Accepted Answer

Epithelial tissue

Question 12
