What is the function of a synovial joint?
Synovial joints (freely movable joints) allow us the free movement to perform skills and techniques during physical activity. Synovial joints have synovial fluid in the joint cavity that lubricates or ‘oils’ the joint so it moves smoothly.
What are the 4 main characteristics of synovial joints?
Synovial joints comprise most of the joints of the extremities and are the most accessible joints to direct inspection and palpation. Synovial joints share important structural components: subchondral bone, hyaline cartilage, a joint cavity, synovial lining, articular capsule, and supporting ligaments.
What are the 6 main types of synovial joints?
There are six types of freely movable diarthrosis (synovial) joints:
- Ball and socket joint. Permitting movement in all directions, the ball and socket joint features the rounded head of one bone sitting in the cup of another bone.
- Hinge joint.
- Condyloid joint.
- Pivot joint.
- Gliding joint.
- Saddle joint.
What are characteristics of synovial joints?
Synovial joints are characterized by the presence of a joint cavity. The walls of this space are formed by the articular capsule, a fibrous connective tissue structure that is attached to each bone just outside the area of the bone’s articulating surface.
What are the 7 synovial joints?
Planar, hinge, pivot, condyloid, saddle, and ball-and-socket are all types of synovial joints.
What are two functions of synovial fluid?
Synovial fluid, present in very small quantities in normal synovial joints, has two functions: lubrication and nutrition. Synovial fluid is a combination of a filtrate of plasma that enters the joint space from the subsynovial capillaries and hyaluronic acid, which is secreted by the synoviocytes.
What are the 7 structures of a synovial joint?
Terms in this set (8)
- Joint capsule. Sleeve-like extension of the periosteum of each of the articulating bones.
- Synovial Membrane. Moist, slippery membrane that lines the inner surface of the joint capsule.
- Articular Cartilage.
- Joint Cavity.
- Menisci (articulatin disks)
- Ligaments.
- Bursae.
- Bony prominences.
What are the 2 types of synovial joints?
Types of synovial joints
- Hinge – these can be found in the elbow, knee and ankle.
- Ball and socket – these types of joint can be found at the shoulder and hip and allow movement in almost every direction.
- Pivot – this joint can be found in the neck between the top two vertebrae.
What is a synovial joint and describe its general structure?
A synovial joint, also known as a diarthrosis, is the most common and most movable type of joint in a mammal’s body. Diarthroses are freely movable articulations. In these joints, the contiguous bony surfaces are covered with articular cartilage and connected by ligaments lined by synovial membrane.
What are the 8 synovial joints?
Where are the 6 synovial joints located?
The six types of synovial joints are the pivot, hinge, saddle, plane, condyloid, and ball-and-socket joints. Pivot joints are found in your neck vertebrae, while hinge joints are located in your elbows, fingers, and knees. Saddle and plane joints are found in your hands.
What are synovial joints made of?
Synovial joints are made up of five classes of tissues: bone, cartilage, synovium, synovial fluid, and tensile tissues composed of tendons and ligaments. The synovial lining in the bursae and tendon sheaths, similar to that within joints, is a slippery, non-adherent surface allowing movement between planes of tissue.
