70
Q

Functions of bones

A
  1. Blood cells are made in the marrow of bones (in their centers) and released into the blood stream
  2. When a body doesn’t ingest enough calcium (as during pregnancy or in post menopausal women), the body uses stored calcium by taking it from the bones. This process has the effect of weakening the bones, which is why it is important to get enough calcium when the body’s needs are high.
  3. The skeleton provides a support for organs and gives shape to the body.

A

The branch of anatomy that deals with joints or articulation.

93
Q

A

Immoveable joints. Sometimes the bones have fused together. Ex: innominate bone made up of ilium, ischium, & pubic bones. The joints between these bones are called sutures.

Diarthrosis joints (juncturae synoviales)

A

Free movement joints (sometimes called a true joint)

  • Articular disk. A disk or meniscus may be situated between dissimilar surfaces to facilitate free movement
  • Articular capsule. A ligamentus capsule surrounds the joint and contains synovial fluid
  • A synovial membrane lines the articular capsule containing the synovial fluid.
  • Ligaments which run from one bone to the other which bind and stabilize the joint.Six types of Diarthrosis joints

A
