Bone Structure & Classification

A bone that is platelike is classified as why type of bone? Flat
The bones of the wrist are examples of what type of bones? Short
The bone of the thigh is an example of what type of bone? Long
Vertebrae are examples of what type of bones? Irregular
The patella (kneecap) is an example of what type of bone? Sesamoid or round
The bones of the skull that form a protective covering of the brain are examples of what type of bones? Flat
Distinguish between the epiphysis and the diaphysis of a long bone. Epiphysis refers to the expanded end of a long bone; diaphysis refers to the shaft between the ends of such a bone.
Describe where cartilage is found on the surface of a long bone. Hyaline cartilage covers the articular ends of a long bone.
Describe where dense irregular connective tissue is found on the surface of a long bone. Dense irregular connective tissue comprises the periosteum that encloses the bone except for its articular ends.
Distinguish the locations and tissues between the periosteum and the endosteum. Periosteum compose of irregular dense connective tissue forms the outer covering of a bone. Endosteum composed of reticular connective tissue lines its hollow, internal chambers.
What structural differences did you note between compact bone and spongy bone? Compact bone has osteons, closely packed together, and spongy bone has large spaces between thin bony plates called trabeculae.
How are these structural differences related to the locations and functions of these two types of bone? Compact bone provides strength in the shaft and along the borders of the bone. Spongy bone reduces the weight of the bone and provides spaces occupied by red marrow.
From your observations, how does the marrow in the medullary cavity compare with the marrow in the spaces of the spongy bone? The marrow of the medullary cavity of an adult is yellow, but marrow in the spaces of spongy bone is red.
