1.03 Functions and disorders of the skeletal system

Functions of Skeletal System 1. Hemopoiesis – formation of red blood cells in the diphysis of the long bones. Mineral storage- Calcium, phosphorus, vit.d Movement-with help from the use of our muscle. Protection-of internal organs. Support-framework for our body. 1.03 Understand the functions and disorders of the skeletal system

DISORDERS OF THE SKELETAL SYSTEM Rickets Pediatric condition(third world countries) Lack of vitamin D Deformed, weak legs, bowing Treatment: Dietary increase of Vit.D, sunlight 1.03 Understand the functions and disorders of the skeletal system

DISORDERS OF THE SKELETAL SYSTEM Abnormal spinal curvatures Kyphosis Lordosis Scoliosis hunchback swayback s-curve 1.03 Understand the functions and disorders of the skeletal system

SKELETAL SYSTEM TRAUMA 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. 1.03 Understand the functions and disorders of the skeletal system

SKELETAL SYSTEM TRAUMA Fractures Greenstick- CHILDREN incomplete break splintering 1.03 Understand the functions and disorders of the skeletal system

SKELETAL SYSTEM TRAUMA 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. 1.03 Understand the functions and disorders of the skeletal system
