---|---|
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. |
