Answer 1

1. Support
2. Movement
3. Protection
4. Blood cell production
5. Mineral storage
6. Energy storage

These functions are essential for maintaining the body’s structure and overall health.

Question 2

What are the three types of joints called?

Answer 2

1. Fibrous joints
2. Cartilaginous joints
3. Synovial joints

Each type of joint has different structures and functions, affecting mobility.

Question 3

What are the six types of synovial joints?

Answer 3

1. Hinge joint
2. Ball-and-socket joint
3. Pivot joint
4. Saddle joint
5. Plane joint
6. Condyloid joint

These joints allow for various ranges of motion and flexibility.

Question 4

Fill in the blank: The term __________ refers to the front of something.

Answer 4

anterior

Anatomical terms help describe locations and orientations of body structures.

Question 5

Fill in the blank: The term __________ refers to the back of something.

Answer 5

posterior

Understanding these terms is crucial for accurate anatomical descriptions.

Question 6

Fill in the blank: The term __________ means towards the midline.

Answer 6

medial

This is important for understanding relative positions of body parts.

Question 7

Fill in the blank: The term __________ means towards the side.

Answer 7

lateral

This term is often used in anatomical descriptions to indicate position.

Question 8

Fill in the blank: The term __________ means closer to the trunk.

Answer 8

proximal

Proximal is used to describe the location of limbs relative to the torso.

Question 9

Fill in the blank: The term __________ means further from the trunk.

Answer 9

distal

This helps in identifying the position of body parts further away from the torso.

Question 10

Fill in the blank: The term __________ means towards the head.

Answer 10

superior

Superior is used to describe positions that are higher on the body.

Question 11

Fill in the blank: The term __________ means towards the feet.

Answer 11

inferior

Inferior describes positions that are lower on the body.

Question 12

What is the function of the joint capsule?

Answer 12

Holds the bones together to protect the joint

The joint capsule is essential for maintaining joint integrity.

Question 13

What is a bursa?

Answer 13

A small fluid-filled sac providing cushion between tendons and bones

Bursa helps to reduce friction during movement.

Question 14

What is the role of cartilage in the skeletal system?

Answer 14

Acts as a shock absorber at the end of bones

Cartilage helps to prevent damage to bones during impact.

Question 15

What does the synovial membrane do?

Answer 15

Releases synovial fluid into the joint

This fluid is crucial for lubrication and nourishment of joint structures.

Question 16

What is synovial fluid?

Answer 16

Fluid that lubricates the joint to reduce friction

It also provides nutrients to articular cartilage.

Question 17

What is the function of ligaments?

Answer 17

Holds the bones together to keep them in place

Ligaments contribute to the stability of joints.
