The bodily system that consists of the bones, their associated cartilages, and the joints, and supports and protects the body, produces blood cells, and stores minerals.

Bone is the substance that forms the skeleton of the body. It is composed chiefly of calcium phosphate and calcium carbonate. It also serves as a storage area for calcium, playing a large role in calcium balance in the blood.

Bones serve some vital functions: as a structural framework for tendons to attach to and provide support for soft tissue. to protect internal organs from injury e.g. the ribs protect the heart and lungs. … Triglycerides which are a source of energy are stored in the yellow bone marrow.

A tendon or sinew is a tough band of fibrous connective tissue that usually connects muscle to bone and is capable of withstanding tension. Tendons are similar to ligaments; both are made of collagen. Ligaments join one bone to another bone, while tendons connect muscle to bone.
Tendon is a highly organized connective tissue joining muscle to bone, capable of resisting high tensile forces while transmitting forces from muscle to bone. The dense, regularly arranged collagenous tissue is made up of fibers, cells of various shapes and ground substance.

The function of tendons is to connect muscle tissues to bones. The same way ligaments connect bones to other bones, tendons act as the bridge between muscles and bones. This connection enables the tendons to regulate forces between muscle tissues during movement so that the body remains stable. 

Cartilage connective tissue is important because it provides support, but is less rigid than bone. It also allows for some flexibility of movement, but has more stability than muscle. The extracellular matrix ofcartilage is produced by cells called chondroblasts.
Cartilage is a flexible connective tissue found in many parts of the body. It can bend a bit, but resists stretching. Its main function is to connect bones together. It is also found in the joints, the rib cage, the ear, the nose, the throat and between the bones of the back.

a ligament is the fibrous connective tissue that connects bones to other bones and is also known as articular ligament, articular larua, fibrous ligament, or true ligament. Ligament can also refer to: Peritoneal ligament: a fold of peritoneum or other membranes.

Ligaments function
It is made up of the bones of the skeleton, muscles, cartilage, tendons,ligaments, joints, and other connective tissue that supports and binds tissues and organs together. … The bones provide stability to the body. Muscles keep bones in place and also play a role in the movement of bones.

Fixed joints

Most fibrous joints are also called “fixed” or “immovable”, because they do not move. These joints have no joint cavity and are connected via fibrous connective tissue. The skull bones are connected by fibrous joints called sutures.In fetal skulls the sutures are wide to allow slight movement during birth.

The site of the junction or union of two or more bones of the body; its primary function is to provide motion and flexibility to the frame of the body.

Ball and socket joints
The ball and socket joint (or spheroidal 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. It enables the bone to move in many places (nearly all directions).

The ball and socket joint provides swinging and rotating movements. The articulating bone is received into the cavity of another bone, allowing the distal bone to move around three main axes with a common center. The joint has stabilizing ligaments that limit the directions and extent to which the bones can be moved.
