Briefly describe the bones that make up the orbit of the eye. Include a description of the portion of the orbit formed by each bone.

Parts of the frontal and sphenoid bones comprise the roof of the orbit. Parts of the zygomatic and sphenoid bones form the lateral wall of the orbit. Parts of the maxilla, zygomatic and palatine bones make up the floor of the orbit. Parts of the maxilla, lacrimal, ethmoid, and sphenoid bones form the medial wall of the orbit.

Briefly describe the five categories of bones found in the human body based on the shape of the bones.

The human body contains five types of bones based on shape. Long bones have greater length than width and consist of a shaft and a variable number of extremities. Short bones are somewhat cube-shaped because they are nearly equal in length and width. Flat bones are generally thin and composed of two nearly parallel plates of compact bones tissue enclosing a layer of spongy bone tissue. Irregular bones have complex shapes and cannot be grouped into any of the previous categories. Sesamoid bones develop in certain tendons where there is considerable friction, tension and physical stress and are shaped similarly to a sesame seed.
