Joints Anatomy and Physiology

These flashcards cover key concepts related to joints, including definitions, classifications, and functions.

What is the definition of a joint (articulation)?

Any point where two bones meet, whether or not the bones are movable.

Which of the following lists the four major categories of joints?

Bony, fibrous, cartilaginous, and synovial joints.

How is a bony joint (synostosis) formed?

When the gap between two bones ossifies and they become a single bone.

Which of the following are the three types of fibrous joints?

Sutures, gomphoses, and syndesmoses.

What correctly describes a gomphosis?

Attachment of a tooth to its socket, held in place by fibrous periodontal ligament.

Which type of cartilaginous joint has bones joined by hyaline cartilage?

Synchondroses.

What is a symphysis?

A type of cartilaginous joint where two bones are joined by fibrocartilage.

Which characteristic defines a synovial joint?

A joint where two bones are separated by a joint cavity, allowing for free movement.

Which of the following factors determine a joint's range of motion?

Structure of the articular surfaces, strength and tautness of ligaments, and action of muscles and tendons.

Which list correctly identifies the six classes of synovial joints?

Ball-and-socket, condylar, saddle, plane, hinge, and pivot joints.

Ball-and-socket, condylar, saddle, plane, hinge, and pivot joints.

A joint that allows only slight movement, such as the intervertebral discs, would be functionally classified as a(n):

Amphiarthrosis.

Which of the following represents a synostosis (bony joint)?

The epiphyseal line of a mature long bone.

Which type of fibrous joint connects the tibia and fibula, allowing for a small amount of movement?

Syndesmosis.

An example of a synchondrosis is:

The epiphyseal plate in a growing long bone.

What is the primary function of synovial fluid within a synovial joint?

To provide nutrients to articular cartilage and lubricate the joint.
