Q

What are the Basic Functions of Bone and the Skeletal System?

A
  1. Support (structural framework of the body. Supports soft tissue and points of attachments for tendons). 2. Protection (protection of internal organs-pelvis/ribs; spine; skull) 3. Assistance in movement (provide a surface for muscular attachment; contraction of muscles will pull on bones to produce movement) 4. Mineral homeostasis (calcium & phosphorous storage) 5. Blood cell production (Red Marrow-Hematopoiesis) 6. Triglyceride storage (yellow marrow mainly adipose cells)

Q

Hormonal Regulation of Calcium Exchange

A

How PTH increases serum calcium: Parathyroid Hormone (PTH): secreted by parathyroid glands. 1. Increases blood calcium level using a negative FB system 2. Acts on the kidneys to decrease the loss of calcium in the urine (more will be retained in the blood) 3. Stimulates the formation of calcitriol (active vitamin D); a hormone that promotes absorption of calcium from foods in the GI tract; into the blood.

CLINICAL CORRELATION: Fractured Clavicle

A

Causes: _ FOOSH can also cause a fractured clavicle; force transmitted can travel throughout the arm _ Blow to the superior part of the anterior thorax [MVA] One of the most frequently fractured bones in the body The junction of the two curves is the weakest part of the clavicle; therefore the Clavicular mid-region is the most common fracture site Even without fracture; compression of the clavicle can cause damage to the brachial plexus (a series of nerves that supply the arm). This structure lies between the 2nd rib and the clavicle. Treatment: Figure 8 sling to keep arm from moving outward.
