Fundamentals of Anatomy & Physiology Lecture on Joints

A comprehensive set of flashcards based on a lecture about joints, covering definitions and key concepts related to joints, movements, classifications, and conditions affecting them.

Joint

Where two bones meet, allowing body movement.

Synarthrosis

An immovable joint that provides very strong connections between bones.

Fibrous joint

A type of joint where bones are connected by dense connective tissue.

Diarthrosis

A freely movable joint, such as a synovial joint.

Amphiarthrosis

A slightly movable joint, stronger than a synovial joint.

Hinge joint

A joint that allows motion in one plane, such as the elbow.

Synovial fluid

A viscous fluid that lubricates joints, filling the joint cavity.

Meniscus

A fibrocartilage pad found between opposing bones in some joints.

Flexion

A movement that decreases the angle between articulating bones.

Extension

A movement that increases the angle between articulating bones.

Opposition

Movement of the thumb toward the palm or other fingers.

Glenohumeral joint

The ball-and-socket joint between the head of the humerus and the glenoid cavity.

Hip joint

A strong ball-and-socket joint between the head of the femur and the acetabulum.

Osteoarthritis

A type of arthritis caused by wear and tear of joint surfaces.

Rheumatoid arthritis

An inflammatory, autoimmune condition affecting joints.

Ligament

A connective tissue that connects bone to bone.

Tendon

A connective tissue that attaches muscles to bones.

Bursae

Small pockets of synovial fluid that cushion areas where tendons and ligaments rub against other tissues.
