2) The major functions of the skeletal system are body support, facilitation of movement, protection of internal organs, storage of minerals and fat, and blood cell formation.
3)The bones of synovial joints are separated by spaces, allowing movement to occur in different directions.
Synovial Ball and Socket, Condylar and Saddle Joints. Ball and socket joints allow the most motion and include the hip and shoulder. ...
Synovial Plane, Hinge and Pivot Joints. ...
Cartilaginous Joints.
4) a)
The ball and socket joint (or spheroid joint) is a type of synovial joint in which the ball-shaped surface of one rounded bone fits into the cup-like depression of another bone. The distal bone is capable of motion around an indefinite number of axes, which have one common center.
b)
A hinge joint is a type of synovial joint that exists in the body and serves to allow motion primarily in one plane. [1] The hinge joint is made up of two or more bones with articular surfaces that are covered by hyaline cartilage and lubricated by synovial fluid.
last answer:
Examples include your elbow joint and your knee joint. Condyloid joint. The condyloid joint allows movement, but no rotation. Examples include your finger joints and your jaw.
