1. Structural support & Body movements
Dr. Ashraf Hussain

3. Structure and Function
Structure & Function
Structure and Function
Forms the body framework
Protects and supports internal organs
Enables the body
to move
Consists of bones, joints and muscles

4. Musculoskeletal System Function
Scaffolding/Support
Protection of vital organs
Locomotion
Production of RBC
Storage of minerals

5. Musculoskeletal support
Skin
Muscles
Bones
Tendons
Ligaments
Cartilage

6. Human Locomotion: B Bones –
1. Provide a place for muscles to attach to 2.
Give the body its general shape and
support structure.
3. Protect structures like brain, heart
lungs, spinal cord…
Act a storage site of mineral like
calcium and phosphate.
Made up of living tissue. Produces red and some white blood cells.

7. Musculoskeletal Structures
Tendons
Bands of connective tissue binding muscles to bones
Cartilage
Connective tissue covering the epiphysis
Surface for articulation
Ligaments
Connective tissue supporting joints
Attach bone ends to each other

8. Dislocation :
Bones have moved from their normal location but no cartilage or tendon damage has occurred.
Sprains – injuries to the ligaments that surround a joint.
Strains – injuries to muscles caused by over exertion.
Tendonitis – Inflammation of a tendon.

9. Disorders:
Osteoarthritis – stiffness of the joints caused by the deterioration of cartilage in the joints.
Rheumatoid Arthritis – more severe progression of osteoarthritis. Joint may become so swollen that it is locked in place.
Gout – uric acid crystals accumulate in the joints causing inflammation.

10. Fracture Break in continuity of bone Closed Open Overlying skin intact
Wound extends from body surface to fracture site
Produced either by bones or object that caused Fracture
Danger of infection
Bone end not necessarily visible

11. Diagnostic, Procedural, and Laboratory Tests Pt 3
Electromyogram
Magnetic resonance imaging (MRI)
Arthrography
Arthroscopy
Computed tomography (CT)
Myelography

12. Good Luck!!
