Functions of Skeletal System
2
1. Hemopoiesis – formation of red blood cells
in the diphysis of the long bones.
2. Mineral storage- Calcium, phosphorus, vit.d
3. Movement-with help from the use of our muscle.
4. Protection-of internal organs.
5. Support-framework for our body.


DISLOCATION VS. SUBLUXATION
 Subluxation occurs when the joint
only comes out of place partially and
goes back into place. move the affected
area to move it back into place. This is
less traumatic and lower in severity than
a dislocation.
 Dislocation happens when ball portion
of the joint comes out completely from
its socket. Usually requires surgery. This
is more severe, more painful and
requires more treatment than a
subluxation.

 A sprain is an injury to a ligament, the tough,
fibrous tissue that connects bones to other bone.
Ligament injuries involve a stretching or a tearing of
this tissue.
 A strain, on the other hand, is an injury to either a
muscle or a tendon, the tissue that connects muscles
to bones. Depending on the severity of the injury, a
strain may be a simple overstretch of the muscle or
tendon, or it can result in a partial or complete tear.
