Types of joints exam review

What is a synovial joint?

A joint characterized by a fluid-filled joint cavity, allowing for a wide range of motion.

Difference between synovial and fibrous joints

Synovial joints allow movement; fibrous joints are immovable and connected by dense connective tissue.

True or false: Cartilaginous joints allow free movement.

False, because cartilaginous joints allow limited movement.

What are the types of synovial joints?

Types include ball-and-socket, hinge, pivot, saddle, condyloid, and gliding joints.

Fill in the blank: A hinge joint allows movement in ____ direction(s).

one direction (flexion and extension).

What is a ball-and-socket joint?

A joint that allows rotation and movement in multiple directions, like the shoulder or hip.

Identify the type: Temporal-mandibular joint.

It is a synovial joint allowing movement of the jaw.

True or false: Fibrous joints are found in the skull.

True, because they connect bones in the skull without movement.

What type of joint is the knee?

The knee is primarily a hinge joint, allowing flexion and extension.

Difference between saddle and condyloid joints

Saddle joints allow movement in two planes; condyloid joints allow for flexion, extension, and some rotation.

What is a pivot joint?

A joint where one bone rotates around another, like the atlantoaxial joint in the neck.

Fill in the blank: Cartilaginous joints are held together by ____.

cartilage.

What is the role of synovial fluid?

Synovial fluid lubricates the joints and reduces friction during movement.

Identify the type: Intervertebral joints.

They are cartilaginous joints allowing limited movement between vertebrae.

True or false: All joints in the body allow for movement.

False, because some joints are immovable, like fibrous joints.
