Unit 6: Skeletal System Test 2024

Front

What is the function of the tibia in the skeletal system?

Back

The tibia, also known as the shinbone, is the larger and stronger of the two bones in the lower leg. It supports the weight of the body and is crucial for walking, running, and jumping.

Front

Identify the fibula and describe its role in the skeletal system.

Back

The fibula is the thinner and smaller bone located alongside the tibia in the lower leg. It provides stability to the ankle and supports muscles of the lower leg.

Front

What is the patella and what is its significance?

Back

The patella, or kneecap, is a small, flat bone that protects the knee joint and improves the leverage of the thigh muscles during movement.

Front

What are metacarpals and where are they located?

Back

Metacarpals are the five long bones in the hand that connect the wrist to the fingers. They play a key role in hand movement and grip.

Front

Describe the humerus and its importance in the skeletal system.

Back

The humerus is the long bone in the upper arm that runs from the shoulder to the elbow. It supports arm movement and is essential for lifting and throwing.

Front

What is the role of the skeletal system in the human body?

Back

The skeletal system provides structure, support, and protection for the body's organs, facilitates movement, produces blood cells, and stores minerals.

Front

Define the term 'articulation' in the context of the skeletal system.

Back

Articulation refers to the point where two bones meet, forming a joint that allows for movement and flexibility.

Front

What are the different types of joints found in the human body?

Back

The main types of joints are: 1) Hinge joints (e.g., elbow), 2) Ball-and-socket joints (e.g., shoulder), 3) Pivot joints (e.g., neck), and 4) Gliding joints (e.g., wrist).

Front

Explain the concept of bone remodeling.

Back

Bone remodeling is the process where old bone tissue is replaced by new bone tissue, allowing bones to adapt to stress and repair themselves.

Front

What is the difference between axial and appendicular skeleton?

Back

The axial skeleton includes the skull, vertebral column, and rib cage, while the appendicular skeleton consists of the limbs and the girdles that attach them to the axial skeleton.
