Q: Which equation best represents the percentage composition of bone matrix, given that water is 20%, organic material is 30-40%, and inorganic material is 40-50%?

Total composition: $\text{Water} + \text{Organic} + \text{Inorganic} = 100\%$

Question 1

Which of the following best describes the primary function of the keratinized stratified squamous epithelium in the epidermis?

Accepted Answer

Protects against abrasion and forms a physical barrier

Question 2

A patient presents with a burn that has destroyed the epidermis and damaged the dermis. Which connective tissue type is most affected in the dermis?

Accepted Answer

Dense irregular connective tissue

Question 3

Which layer of the skin is primarily responsible for vitamin D synthesis in response to sunlight?

Accepted Answer

Epidermis

Question 4

A biopsy of a patient's trachea reveals a single layer of cells with nuclei at varying levels and cilia. Which epithelial tissue is present?

Accepted Answer

Pseudostratified columnar epithelium

Question 5

Which equation best represents the percentage composition of bone matrix, given that water is 20%, organic material is 30-40%, and inorganic material is 40-50%?

Accepted Answer

Total composition: $	ext{Water} + 	ext{Organic} + 	ext{Inorganic} = 100\%$

Question 6

Which tissue type is most likely to be found lining the alveoli of the lungs, facilitating rapid gas exchange?

Accepted Answer

Simple squamous epithelium

Question 7

A patient with a ruptured tendon is most likely to have damage to which connective tissue type?

Accepted Answer

Dense regular connective tissue

Question 8

Which of the following is TRUE regarding cartilage?

Accepted Answer

Cartilage relies on diffusion through its matrix for nutrient and waste exchange

Question 9

Which muscle tissue is characterized by striations, multiple peripheral nuclei, and voluntary control?

Accepted Answer

Skeletal muscle

Question 10

A histological slide shows cells with large fat-filled cytoplasm. Which tissue is most likely being observed?

Accepted Answer

Adipose connective tissue

Question 11

Which of the following best explains why epithelial tissues lack blood vessels?

Accepted Answer

Epithelial tissues rely on diffusion from capillaries in underlying connective tissue

Question 12

Which connective tissue type forms the supportive framework (stroma) for organs such as the spleen and lymph nodes?

Accepted Answer

Reticular connective tissue

Question 13

A patient with a bladder disorder is found to have abnormal expansion and contraction of the bladder wall. Which epithelial tissue is most likely affected?

Accepted Answer

Transitional epithelium

Question 14

Which of the following is a function of the hypodermis (subcutaneous tissue)?

Accepted Answer

Provides protective functions and stores fat

Question 15

Which equation best represents the relationship between the number of cell layers and the function of epithelial tissue?

Accepted Answer

If $n = 1$, then tissue is specialized for diffusion; if $n > 1$, then tissue is specialized for protection.

Question 16

Which connective tissue is most likely to be found in the external ear, providing flexibility while maintaining shape?

Accepted Answer

Elastic cartilage

Question 17

Which of the following is TRUE regarding the basement membrane in epithelial tissues?

Accepted Answer

It anchors epithelial cells to underlying connective tissue

Question 18

Accepted Answer

Heart

Question 19

Which tissue type is most likely to be found in the male urethra, supporting both protection and secretion?

Accepted Answer

Stratified columnar epithelium

Question 20

Which equation best represents the relationship between sweat production and temperature regulation in the integumentary system?

Accepted Answer

If $T_{body} > T_{ambient}$, then $	ext{Sweat production} \uparrow$ to promote heat loss.
