D) In the knee joint
E) In the skin

C) In the tip of the nose and ends of long bones
Explanation: Hyaline cartilage is typically found in areas such as the tip of the nose, the ends of long bones, and the fetal skeleton, providing support and flexibility.

Connective Tissue Components

Which of the following is NOT a component of connective tissue?
A) Specialized cells
B) Ground substance
C) Protein fibers
D) Epithelial cells
E) All of the above are components

D) Epithelial cells
Explanation: Epithelial cells are not a component of connective tissue; rather, connective tissue is made up of specialized cells, ground substance, and protein fibers.

Supportive Connective Tissue

How does spongy bone compare to compact bone?
A) Heavier and denser
B) Lighter but strong
C) Softer and more flexible
D) More rigid
E) Less vascularized

B) Lighter but strong
Explanation: Spongy bone is lighter than compact bone but still maintains strength, making it essential for the structure of long bones.

Epithelial Tissue Characteristics

What defines stratified epithelium?
A) It has a single layer of cells.
B) It is composed of multiple layers of cells.
C) It is always found in the respiratory tract.
D) It is less protective than simple epithelium.
E) It consists only of squamous cells.

B) It is composed of multiple layers of cells.
Explanation: Stratified epithelium is characterized by having multiple layers of cells, providing greater protection against abrasion and wear.

Types of Tissues

What is the primary function of connective tissue?
A) To conduct nerve impulses
B) To cover body surfaces
C) To bind and support body parts
D) To move the body and its parts
E) To store energy

C) To bind and support body parts
Explanation: Connective tissue's main role is to bind and support various parts of the body, providing structure and stability to organs and tissues.

Types of Tissues

What is the primary role of epithelial tissue?
A) To bind and support body parts
B) To conduct nerve impulses
C) To cover body surfaces and line body cavities
D) To store fat
E) To facilitate movement

C) To cover body surfaces and line body cavities
Explanation: Epithelial tissue serves the essential function of covering body surfaces and lining cavities, providing protection and facilitating absorption and secretion.

p.26
Epithelial Tissue Characteristics

Which of the following is NOT a function of epithelial tissue?
A) Absorption
B) Secretion
C) Sensation
D) Support
E) Protection

D) Support
Explanation: While epithelial tissue serves functions such as absorption, secretion, sensation, and protection, it does not primarily provide support, which is a function more associated with connective tissues.

Epithelial Tissue Characteristics

What is the role of cilia in certain epithelial tissues?
A) To provide structural support
B) To facilitate movement of substances
C) To absorb nutrients
D) To protect against pathogens
E) To store energy

B) To facilitate movement of substances
Explanation: Cilia are hair-like structures on the surface of certain epithelial cells that help in moving substances across the epithelial surface, such as in the respiratory tract where they help clear mucus.

Connective Tissue Components

What role do protein fibers play in connective tissue?
A) They provide energy to the cells
B) They help in the contraction of muscles
C) They provide strength and support
D) They are responsible for nerve transmission
E) They form the outer layer of skin

C) They provide strength and support
Explanation: Protein fibers in connective tissue are crucial for providing strength and structural support, contributing to the overall integrity and function of the tissue.
