Bone Types
Long Bones:
Long bones are dense, hard bones that provide strength stability and mobility. For example the femur is a long bone. A long bone has two ends and a shaft. In the finger some bones are long bones, due to the shape of the bones despite them being short. http://umm.edu/health/medical/ency/articles/long-bones
Short Bones:
Short bones are as long as they are wide. They’re function of them is to provide stability and little movement. http://www.teachpe.com/anatomy/types_of_bones.php
Flat Bones:
Flat bones are strong plates and their main function is to provide protection to the vital organs. An example is the scapula. http://www.teachpe.com/anatomy/types_of_bones.php
Irregular bones;
These bones don’t fall into any category

The periosteum is an important part of the skeletal system and is found as a membrane along the outside of the bone. https://www.reference.com/science/function-periosteum-c76e79bbe59f9be0
Compact bone: The function of compact bone is structural support, both for overall body structure and the protection of cancellous bone, which contains marrow. Mature compact bone is layered and very dense, with the mineral calcium phosphate embedded in collagen proteins, with tiny spaces for the living, bone-producing cells. https://www.reference.com/science/function-compact-bone-16a51420575e03ce
Bone Marrow: Bone marrow is the soft, flexible connective tissue within bone cavities. A component of the lymphatic system, bone marrow functions primarily to produce blood cells and to store fat. Bone marrow is highly vascular, meaning that it is richly supplied with a large number of blood vessels. There are two categories of bone marrow tissue: red marrow and yellow marrow. From birth to early adolescence, the majority of our bone marrow is red marrow.

Gliding joints allow the bones to glide past one another in any direction along the plane of the joint – up and down, left and right, and diagonally. Slight rotations can also occur at these joints, but are limited by the shape of the bones and the elasticity of the joint capsule surrounding them. http://www.innerbody.com/image_skel07/skel32.html
Condyloid joint:
A condyloid joint (also called condylar, ellipsoidal, or bicondylar) is an ovoid articular surface, or condyle that is received into an elliptical cavity. This permits movement in two planes, allowing flexion, extension, adduction, abduction, and circumduction
Saddle joint:
A saddle joint is a synovial joint where one of the bones forming the joint is shaped like a saddle with the other bone resting on it like a rider on a horse. Saddle joints provide stability to the bones while providing more flexibility than a hinge or gliding joint. The bone sitting on the saddle can move in an oval shape relative to the other bone, similar to a condyloid joint
