CHAPTER 13 BONES – Flashcards

In 1932, the F.B.I. announced the opening of its first crime lab. The Smithsonian Institution became a working partner, aiding in the identification of human remains.

Bones originate from living cells called osteoclasts.

During the development of the fetus, bones begin as soft cartilage, the same flexible material that makes up the ears. Osteoblasts migrate to the centers of cartilage production and deposit materials, such as calcium phosphate, that harden to form bone. This process is called Ossification.

Bones breathe and consume energy like any other living cells.

Osteoclasts, one type of bone cell, are specialized to create bone.

Calcium, a mineral vital to normal metabolism, may be 'borrowed' from bone when levels in the blood are low. Osteoclasts dissolve the bone and release calcium into the blood. Continued failure to eat enough calcium can result in a weakening of the bones. This condition is called:

When bones become injured, the osteoclasts secrete:

After all bones have become fully developed, an adult has 206 bones. A baby has:

A joint is the location where bones meet (articulate). Joints contain several kinds of connective tissue. These include:

At thirty years of age, an adult's bones deteriorate faster than they are built. This deterioration can be slowed:

The number of bones and their condition can tell an investigator about a person's:

Osteobiography literally translates as the story of life as told by:

Compared to a women's skeleton, a man's skeleton is usually:

To distinguish between the male and female pelvis, the sub pubic angle is:

The scientific study of the origin, behavior, as well as the physical, social, and cultural development of humans is:

The main suture marks on a skull, marking where the bones are growing together, are:

DNA profiling usually uses nuclear DNA, which is found in the nucleus of white blood cells and other body tissues. Bone contains:

Bones exposed to the elements for long periods of time are often damaged by:

The strength of bone decreases as it ages or dries out. Living bone is actually quite flexible when compared to dry and brittle bones and therefore, they break in different ways. Living bones will usually shatter in a:

When the head of a long bone, like the thigh or upper arm bone has totally fused to its shaft, this is another indication of:
