Periosteum

What is the periosteum?

Double-layered connective tissue that covers and nourishes the entire bone except the joint surfaces.

p.1
Structural Classification of Joints

What is the structural classification of fibrous joints?

Bones joined by collagen fibers of connective tissue.

p.1
Structural Classification of Joints

What is the structural classification of synovial joints?

Articulating bones are separated by fluid-filled cavities. Most joints are classified this way.

p.1
Epiphysis

What is the epiphysis?

The end of a long bone, attached to the shaft.

p.1
Structural Classification of Joints

What are syndesmoses?

Fibrous joint where a junction of bones is held together by ligaments.

p.1
Synovial Fluid

What is synovial fluid?

Fluid secreted by the synovial membrane; lubricates joint surfaces and nourishes articular cartilages.

p.1
Structural Classification of Joints

What are symphyses?

Bones are joined by fibrocartilage.

p.1
Meniscus

What is the meniscus?

Padlike cartilage in the knee joint.

p.1
Structural Classification of Joints

What are synchondroses?

Joints of hyaline cartilage between the shaft and the epiphyseal plates of growing long bones.

p.1
Articular Cartilage

What is articular cartilage?

Hyaline cartilage covering bone ends at movable joints.

p.1
Structural Classification of Joints

What is the structural classification of cartilaginous joints?

Bones joined by cartilage.

p.1
Functional Classification of Joints

What is the functional classification of synarthroses?

Functional classification of immovable joints.

p.2
Functional Classification of Joints

What are Amphiarthroses?

Amphiarthroses are a functional classification of slightly movable joints.

p.1
Diaphysis

What is the diaphysis?

Elongated shaft of a long bone.

p.1
Structural Classification of Joints

What are sutures?

Fibrous joints found only between bones of the skull.

p.2
Functional Classification of Joints

What are Diarthroses?

Diarthroses are a functional classification of freely movable joints, also known as synovial joints.

p.1
Epiphyseal Plate

What is the epiphyseal plate?

Plate of hyaline cartilage at the junction of the diaphysis and epiphysis that provides for growth in length of a long bone.

p.1
Structural Classification of Joints

What are gomphoses?

Fibrous joint where a tooth is attached to a socket with the periodontal ligament.

p.1
Joint Cavity

What is the joint cavity?

A unique feature of synovial joints that contains a small amount of synovial fluid.
