Answer 1

Answer:

A synovial joint is surrounded by a two-layer _____joint capsule_______ which encloses a fluid-filled space called the _____synovial cavity_______ . The outer layer of this structure consists of _____dense connective tissue_______ which is continuous with the periosteum of each bone. The outer layer may be reinforced by _____ligaments_______ which are bundles of collagenous fibers. Some of these bundles are part of the capsule while other are located outside of the capsule. By definition, the structures, such as some ligaments, that are located outside the capsule are called ____accessory structures________ . The inner layer of the joint capsule is the ______synovial membrane______ , consisting of ______subintima and intima_____ . the inner lining of the joint capsule secretes a fluid called ______synovial fluid______ . this fluid is viscous, and it moistens and lubricates the surfaces within the joint capsule.

Explanation: The makeup of joints that connects bones of the body are described. The joints are contained in a capsule of two layers known as the joint or articular capsule forming the synovial cavity that is filled with synovial fluid, a viscous, that serves as lubricant within the joint. The bilayer of the capsule has an outer and an inner layer. The outer layer is

fibrous and dense and is composed of connecting tissues while the inner layer, known as the synovial membrane is composed of a subintima (which contains a range of connective tissues from fibrous to fatty and lastly areolar) and an intima (which is composed of an ultra thin layer of cells).

Answer 2

Answer;

-Joint capsule

-Synovial cavity

A synovial joint is surrounded by a two layer joint capsule which encloses a fluid filled space called the synovial cavity.

Explanation;

• Synovial joint is a type of a joint that joins bone with fibrous joint capsule which is continuous with periosteum of the bones that have been joined.  

• Joint capsule is an envelope that encloses the synovial joint and is also known as the articular capsule.

• Joint capsule comprises of an outer fibrous layer membrane and the inner synovial layer membrane.

Answer;

Dense connective tissue

The outer layer of this structure consists of dense connective tissue which is continuous with the periosteum of each bone

Explanation;

• The outer layer of the joint capsule is a fibrous membrane that is attached to the circumference of the articular end of each bone on the joint, therefore it surrounds the articulation.  

• This layer is made up of dense connective tissue which is irregular that is continuous with the periosteum of each bone in the joint. The tissue is a long spongy tissue

Answer;

Ligaments

The outer layer may be reinforced by ligaments which are bundles of collagenous fibers. Some of these bundles are part of the capsule while other are located outside of the capsule.

Explanation;

• Ligaments are fibrous connective tissues that help in the articulation of bones to other bones. Ligaments are bundles of collagenous fibers which appear as a crisscross bands which attach bone to bone and help in the stabilization of joints.

• Ligaments surrounds a joint to give it support and also limits the movement of these joints. Therefore when ligaments are damaged, the joints involved becomes unstable.

Answer;

Accessory structure

By definition, the structures, such as some ligaments, that are located outside the capsule are called accessory structures.

Explanation;

• The synovial joint such as the knee joint contains a synovial cavity and dense, irregular connective tissue which makes the joint capsule normally associated with accessory ligaments. These structures are called the accessory structures of the synovial joints.

• The accessory structures are the pieces that help to strengthen and connect the joint. They include the fibrocartilage, fat pads, tendons, Accessory, Extracapsular, intracapsular ligaments and the bursae.

Answer;

Synovial membrane

The inner layer of the joint capsule is the synovial membrane, consisting of loose connective tissue.

Explanation;

• Synovial membrane is a connective tissue which lines the inner surface of the joint capsules in a synovial joint and the tendon sheath. It may be described as a layer that lines the cavities of synovial joints bursae and the tendon sheaths.
• The membrane functions to secrete the synovial fluid which lubricates the articulating joints.  

Answer;

Synovial fluid  

The inner lining of the joint capsule secretes a fluid called synovial fluid. This fluid is viscous, and moistens and lubricates the surfaces within the joint capsule

Explanation;

• Synovial fluid is a special type of viscous fluid that is secreted by the synovial membrane in a synovial joint such as knee joint whose function is primarily lubrication of the joint.
• The fluid contains special contents such as hyaluronan, lubricin and the interstitial fluid which help in the reduction of friction between the articular cartilage of synovial joints when the joints are moving.
