Question 1

Which of the following best describes the difference between merocrine and holocrine modes of secretion in human exocrine glands?

Accepted Answer

Merocrine glands secrete products by exocytosis without damaging the cell, while holocrine glands release products when the entire cell ruptures and dies.

Question 2

A patient presents with excessive oil production in the skin. Which type of gland and mode of secretion is most likely responsible for this condition?

Accepted Answer

Simple branched alveolar gland with holocrine secretion

Question 3

Which equation correctly represents the relationship between the number of ducts ($n$) and the number of secretory units ($s$) in a compound exocrine gland, assuming each duct supplies 3 secretory units?

Accepted Answer

$s = 3n$

Question 4

Which connective tissue type is most likely to be found in tendons, and what is its primary function?

Accepted Answer

Dense regular connective tissue; resists pulling forces in one direction

Question 5

A histological sample shows a gland with multiple ducts and secretory units arranged in clusters. Which type of gland is this most likely to be?

Accepted Answer

Compound alveolar gland

Question 6

Which of the following is NOT a main class of connective tissue?

Accepted Answer

Muscle tissue

Question 7

If a gland secretes its product by pinching off a portion of the cell membrane, which mode of secretion is being used?

Accepted Answer

Apocrine

Question 8

Which connective tissue type is most abundant and widely distributed in the human body?

Accepted Answer

Loose connective tissue

Question 9

A gland is classified as 'simple' if it has which of the following characteristics?

Accepted Answer

A single unbranched duct

Question 10

Which of the following best explains why holocrine glands are more prone to inflammation compared to merocrine glands?

Accepted Answer

Holocrine secretion involves cell rupture, releasing cell debris that can trigger an inflammatory response.

Question 11

Which connective tissue type is specialized for energy storage and insulation?

Accepted Answer

Adipose tissue

Question 12

A compound tubular gland differs from a simple tubular gland in which way?

Accepted Answer

It has multiple branched ducts and secretory units

Question 13

Which of the following equations best represents the total volume of secretory product ($V$) released by a holocrine gland, if each cell releases $v$ units and $c$ cells rupture per hour?

Accepted Answer

$V = v 	imes c$

Question 14

Which connective tissue type forms the framework of lymphoid organs such as the spleen and lymph nodes?

Accepted Answer

Reticular connective tissue

Question 15

A gland with a duct that branches repeatedly and secretory units shaped like sacs is classified as:

Accepted Answer

Compound alveolar gland

Question 16

Which of the following is a function of connective tissue proper?

Accepted Answer

Providing structural support and binding other tissues

Question 17

Which type of gland is most likely to be involved in sweat production?

Accepted Answer

Simple coiled tubular gland

Question 18

If a gland is classified as 'compound tubular,' what does this indicate about its structure?

Accepted Answer

It has multiple branched ducts and tubular secretory units

Question 19

Which of the following best describes the role of cartilage as a connective tissue?

Accepted Answer

Forms rigid but flexible support structures in the body

Question 20

A gland that releases its product by exocytosis without loss of cellular material is using which mode of secretion?

Accepted Answer

Merocrine
