-The appendicular skeleton consists of the shoulder girdles, upper limbs, pelvic girdles, and lower limbs.
-Bones are living tissue that make up the skeleton. They are primarily composed of three types of tissue. These three types are compact tissue, cancellous tissue, and subchondral tissue.
-Compact tissue is the outer layer of bones and is harder than the other layers.
-Cancellous tissue is a sponge-like layer of tissue inside the bones.
-Subchondral tissue is the tissue at the end of bones and is covered by cartilage.
-The three major joint types are fibrous joints (synarthroses), cartilaginous joints (amphiarthroses), and …show more content…
-Synovial joints, or diarthroses, are freely movable joints.
-Ball and socket joints (synovial joints) are located in the shoulder and hip. They are made up a bone with a spherical head attached to a bone with a cup-like socket. This joint allows the most movement. (abduction, adduction, flexion, extension, and circumduction)
-The elbow joint is a hinge joint that consists of the end of the ulna and radius and the end of the humerus. It allows flexion and extension movements and can only extend approximately 180 degrees.
-Gliding joints (synovial joint) are usually a group of cube-shaped bones that can either move up and down, left and right, or diagonally. They can be found in the foot, hand, and ankle.
-Hinge joints (synovial joints) are made of bone, cartilage, synovium, muscle, and ligaments. They can move on one axis to flex or extend. Some examples of hinge joints are the elbow joint and the knee joint.
-The hip joint is a ball and socket joint that consists of the hip bone (os coxa) and femur. It supports our body weight, the force of the strong hip and leg muscles, and it allows for movements such as running, walking, and
