What are articular discs of synovial joints?

The articular disk (or disc) is a thin, oval plate of fibrocartilage present in several joints which separates synovial cavities. This separation of the cavity space allows for separate movements to occur in each space.

What is the function of articular cartilage quizlet?

What is Articular Cartilage? Hyaline cartilage covering bone ends at moveable joints. What is the purpose of the outer layer (fibrous capsule) of the Articular Capsule? It strengthens the joint so that the bones don’t pull apart.

What is the articular capsule quizlet?

a joint capsule or articular capsule is an envelope surrounding a synovial joint. Each joint capsule has two parts: an outer fibrous layer or membrane, and an inner synovial layer or membrane.

Where are articular discs of synovial joints found?

A few synovial joints of the body have a fibrocartilage structure located between the articulating bones. This is called an articular disc, which is generally small and oval-shaped, or a meniscus, which is larger and C-shaped.. Synovial joints are often further classified by the type of movements they permit.

What are articular discs?

Each articular disk is the structure of dense fibrous connective tissue and divides the joint cavity into two separate compartments, the upper diskotemporal space, and lower diskomandibular space.

What are articular discs made of?

The articular disc of the temporomandibular joint (TMJ) is composed of fibrocartilage, and the extracellular matrix of this disc is composed mainly of collagen, glycosaminoglycan and proteoglycans.

What is the function of articular cartilage?

Articular cartilage is the smooth, white tissue that covers the ends of bones where they come together to form joints. Healthy cartilage in our joints makes it easier to move. It allows the bones to glide over each other with very little friction. Articular cartilage can be damaged by injury or normal wear and tear.

Which of the following are functions of articular cartilage?

Articular cartilage is a highly specialized connective tissue of diarthrodial joints. Its principal function is to provide a smooth, lubricated surface for articulation and to facilitate the transmission of loads with a low frictional coefficient.

What is articular capsule?

In anatomy, a joint capsule or articular capsule is an envelope surrounding a synovial joint. Each joint capsule has two parts: an outer fibrous layer or membrane, and an inner synovial layer or membrane.

What are joint capsules?

The joint capsule is a dense fibrous connective tissue that is attached to the bones via specialized attachment zones at the end of each involved bone.

Where are articular discs found?

When complete they are called disks; when incomplete they are called menisci. Disks are found in the temporomandibular joint of the lower jaw, the sternoclavicular (breastbone and collarbone) joint, and the ulnocarpal (inner forearm bone and wrist) joint.

What does articular disc mean?

The articular disc is a somewhat oval body of fibrous tissue, which is convex on its upper surface to accommodate itself to the shape of the articular fossa and concave on its inferior surface to conform to the head of the mandible.
