Bone Types
Long Bones: Long bones are hard, dense bones that provide strength and mobility. The thigh bone the femur is a long bone. Some bones in the fingers are classified as long bones, even though they are short in length.
Short Bones: Their primary function is to provide support and stability with little to no movement. Examples of these bones include the tarsals in the foot and the carpals in the hand.
Flat bones: These bones are expanded into broad, flat plates, as in the cranium, the ilium, sternum and the rib cage.
Irregular Bones: Irregular bones serve various purposes in the body, such as protection of nervous tissue, and maintaining pharynx and trachea support, and tongue attachment (the hyoid bone).
Sesamoid Bones: A small independent

Examples are where the teeth are held to their bony sockets and at both the radioulnar and tibiofibular joints.

Classification of Joints
Fibrous joints
Fibrous: This type of joint is held together by only a ligament. Examples are where the teeth are held to their bony sockets and at both the radioulnar and tibiofibular joints.
Classification of joints
Cartilaginous
Cartilaginous: These joints occur where the connection between the articulating bones is made up of cartilage for example between vertebrae in the spine.
Synovial Joints
Synovial: Synovial joints are by far the most common classification of joint within the human body. There are 6 types of synovial joints which are classified by the shape of the joint and the movement available.

6 different types of synovial joints:
Hinge:
A hinge joint is a common class of synovial joint that includes the ankle, elbow, and knee joints. Hinge joints are formed between two or more bones where the bones can only move along one axis to flex or

For example, a stable rib cage and spine enable the lungs to fully inflate when breathing. Conditions such as osteoporosis of the spine and broken ribs can alter the shape of the chest and impair this vital body function.
Support
The skeleton provides support to the body and keeps the internal organs in their proper place. The strong bones of the spine, pelvis and legs enable people to stand upright, supporting the weight of the entire body.
Movement
The skeletal bones are held together by ligaments, and tendons attach the muscles to the bones of the skeleton. The muscular and skeletal systems work together as the musculoskeletal system, which enables body movement and stability.
Protection
The skeleton protects the internal organs from damage by surrounding them with bone. Bone is living tissue that is hard and strong, yet slightly flexible to resist breaking. The strength of bone comes from its mineral content, which is primarily calcium and phosphorus. The flexibility is due to a substance called collagen. Examples of important protecting bones of the skeleton include the skull, spinal column and rib cage, which protect the brain, spinal cord, and heart and
