Understanding Human Joints and Articulations Quiz

1. What is an articulation?

A type of painting technique.

A musical performance.

A method of communication between animals.

Or joint, is a point of contact between bones.

An articulation refers to a joint, which is a point of contact between bones in the body. It is crucial for movement and stability.

Explanation

An articulation refers to a joint, which is a point of contact between bones in the body. It is crucial for movement and stability.

2. How are joints classified structurally?

Joints are classified based on the flexibility of movement they allow.

Joints are named according to the type of connective tissue that joins the bones together (fibrous or cartilaginous) joints.

Joints are classified based on the size of the bones they connect.

Joints are classified based on the location in the body where they are found.

Structural classification of joints is based on the type of connective tissue between the bones, not on other factors like flexibility, location, or bone size.

Explanation

Structural classification of joints is based on the type of connective tissue between the bones, not on other factors like flexibility, location, or bone size.

3. What type of joints are synarthroses?

Are partially movable joints.

Are freely movable joints.

Are immovable joints.

Are temporary joints.

Synarthroses are joints that are immovable and provide stability to the skeletal system.

Explanation

Synarthroses are joints that are immovable and provide stability to the skeletal system.

4. What are amphiarthroses?

Ball and socket joints

Are slight movable joints.

Immovable joints

Hinge joints

Amphiarthroses are joints that allow for slight movement, such as the vertebral joints in the spine. They are not completely immovable like some joints, function differently than hinge joints, and are not as mobile as ball and socket joints.

Explanation

Amphiarthroses are joints that allow for slight movement, such as the vertebral joints in the spine. They are not completely immovable like some joints, function differently than hinge joints, and are not as mobile as ball and socket joints.

5. What are diarthroses?

Are only found in the skull.

Are freely movable joints.

Are immovable joints.

Are not found in the human body.

Diarthroses are a type of joint that allows for a wide range of movement, making them freely movable joints in the body.

Explanation

Diarthroses are a type of joint that allows for a wide range of movement, making them freely movable joints in the body.

6. What is the purpose of functional classification in joint movement?

It differentiates between voluntary and involuntary movements of joints.

Scheme is used, joints are divided into three classes according to the degree of movement.

It categorizes joints based on their size and shape.

It determines the primary functions of joints in the skeletal system.

Functional classification in joint movement refers to the categorization of joints based on the degree of movement they allow, rather than size, shape, primary function, or voluntary vs involuntary movements.

Explanation

Functional classification in joint movement refers to the categorization of joints based on the degree of movement they allow, rather than size, shape, primary function, or voluntary vs involuntary movements.
