.Bone types: Shape
- Long bones: these bones give shape and act as levers. They aid in support, locomotion and prehension (limbs)
- elongated bones: these bones are notable extended in one direction and lack a medullary cavity. (ribs)
-Irregular bones: these bones are irregular in shape and lie in the medial plane, they protect the spinal cord and provide support for the body. (vertebrae)
-short bones: these bones are nearly similar dimension in length, breadth and thickness (cuboidal). They have no marrow cavity but the interior is filled with marrow spaces. Their primary function is shock absoprtion during locomotion. (sesamoids)
-flat bones: these bones are usually thin and plat-like and consist of 2 plates of compact bone separated by spongy bone and marrow. They function as protection of vital organs and as an expanded area for attachment of muscles. (skull)
Bone types: Structure
- compact bone: this forms the outer shell of bones and is usally very solid mass of bony tissue arranged in concentric layers (haverisan systems). It is found primarily in the shaftof long bones and forms the outer shell around cancellous bone at the end of the joints and the vertebrae. The basic firstlevel strcture of the compact bone are osteons.
- Periosteum: this is a collagen sheath on the outer surface of bone and normally consists of an outer protective fibrous layer and an inner cellular osteogenic layer, at the joint, the periosteum joins the joint capsule.
- Cancellous/trabecular: this bone type is located beneath the ompact bone and is a meshwork of tiny bony bars (trabeculae). It forms the bulk of shortbones and extremities and partial extremities of long bones. The first basic structure is trabeculae and the unit of bone formation is still the osteon.
bone types: function
- Pneumatic bone: this is bone that contains air cavities known as sinuses which are lined with mucous membranes and communicate with the exterior or to airways.
