Define each of the following terms: synarthrosis, syndesmosis, synarthrosis, which of these terms is a functional classification of joints?
To review:
Synarthrosis, syndesmosis, and synchondrosis and which of them is the functional classification of the joints.
Introduction:
Joint is the connection between two bones in the body that links the skeletal system into the function group. Some joints are moveable and allow the movement at different degrees whereas, some are immovable. Joints are mainly categorized into synovial, fibrous, and cartilaginous joints. The skeletal system provides mechanical support to the internal parts of the body and it also maintains the posture of the body.
Explanation of Solution
Synarthrosis joint is the type of joint that is immovable in nature. This joint gives a strong connection between adjacent bones and protects the internal structures such as the heart and the brain. A syndesmosis is a fibrous joint present between the bones and lined by the ligaments.
Synchondrosis is a cartilaginous joint and it is a immovable joint that is present between two bones. Synchondrosis joint is present in the spinal vertebrae.
The joints are classified on the basis of structures and functions. The structural classification of the joints includes synovial, fibrous, and cartilaginous joints whereas, the functional classification of the joints includes synarthroses, amphiarthroses, and diarthroses.
