Formative Assessment – Chapter 8 The Skeletal System – Joints

These flashcards cover key concepts from the lecture on the skeletal system and joints, including joint classifications, types, structures, motions, injuries, and conditions.

What are the two classifications of joints?

Fibrous joints and cartilaginous joints.

What are the three types of fibrous joints?

Sutures, syndesmoses, and gomphoses.

Give an example of a suture joint.

The joints found between the bones of the skull.

Give an example of a syndesmoses joint.

The joint between the tibia and fibula.

Give an example of a gomphoses joint.

The joint between teeth and their sockets.

What are the two types of cartilaginous joints?

Synchondroses and symphyses.

What is an example of a synchondrosis joint?

The joint between the first rib and the sternum.

What is an example of a symphysis joint?

The pubic symphysis.

What general structures can be found in a synovial joint?

Articular cartilage, synovial cavity, synovial fluid, and ligaments.

What types of motion do synovial joints allow?

Flexion, extension, abduction, adduction, rotation, and circumduction.

What determines synovial joint stability?

The shape of the articulating surfaces, the strength of the ligaments, and muscle tone.

List the six different types of synovial joints.

Hinge, pivot, ball-and-socket, saddle, condyloid, and plane.

What type of motion is allowed by hinge joints?

Flexion and extension.

What type of motion is allowed by pivot joints?

Rotation.

What type of motion is allowed by ball-and-socket joints?

Multidirectional movement and rotation.

What type of motion is allowed by saddle joints?

Allows for movements back and forth and side to side.

What type of motion is allowed by condyloid joints?

Movements in two planes including flexion, extension, adduction, and abduction.

What type of motion is allowed by plane joints?

Sliding or gliding movements.

List three common joint injuries.

Sprains, strains, and dislocations.

What is bursitis?

Inflammation of the bursa, typically caused by repeated trauma or overuse.

What is tendonitis?

Inflammation of the tendon, often due to repetitive stress.

What is arthritis?

Inflammation of the joints.

What is osteoarthritis?

A degenerative joint disease caused by the breakdown of cartilage.

What is rheumatoid arthritis?

An autoimmune condition that causes chronic inflammation of joints.

What is gouty arthritis?

A type of arthritis characterized by the deposition of uric acid crystals in the joints.

What condition is Lyme disease associated with?

It can lead to Lyme arthritis, where the joints become inflamed.
