  1. Musculoskeletal System( Bones, Joints and Muscles ) Dr. Walid Daoud Assistant Professor

  2. Skeletal System Functions: - Protection of vital organs. - Movement. - hematopoiesis. - A storehouse for minerals.

  3. Structure and Types of Bones 1.Long bones: Found in the extremities and consist of the following: diaphysis, epiphyses, articular cartilage and periosteum. 2.Flat bones. 3.Short bones. 4.Irregular bones.

  4. Divisions of Skeletal System 1. Axial skeleton: Bones of skull, thorax and vertebral column. 2. Appendicular skeleton: Bones of shoulder, upper extremities, hips, and lower extremities. Human skeleton consists of 206 bones.

  5. Vertebral Column It is composed of 26 bones (vertebrae) separated by intervertebral discs: - Cervical vertebrae (7). - Thoracic vertebrae (12). - Lumbar vertebrae (5). - Sacral vertebrae (5). - Coccyx (1-3).

  6. Thorax It contains 2 important organs the heart and lungs. 1. The ribs: 12 pairs (24 ribs) -Tue ribs (upper 7 pairs) -False ribs (lower 5 pairs) -Floating ribs (last 2 pairs). 2. The sternum. 3. The costal cartilages

  7. Pelvic Girdle (Pelvis) Itsupports the sigmoid colon, rectum, bladder and other soft organs. Female pelvis is more shallow but wider than male pelvis. Pelvis is divided into: ilium, ischium and pubis, symphysis pubis, sacrum and coccyx.

  8. Bone Markings Projections (processes): A condyle, a tuberosity, a trochanter. Depressions: A sinus, a foramen, a fissure, a fossa. Joints or Articulations Body Movements: Abduction, adduction, supination, pronation, inversion and eversion.

  9. Muscles: - Cardiac muscle. - Smooth muscles. - Skeletal muscles. Connective Tissue Covering: Fascia, epimysium, perimysium and endomysium. Attachments: Fibrous attachment, tendon or aponeurosis

  10. Disorders of the Musculoskeletal System Bones: - Osteomyelitis. - Ankylosis. - Osteoma. - Exososes. - Sarcomas. - Osteitis deformans.

  11. Disorders of the Musculoskeletal System Joints: - Rheumatoid arthritis. - Gout. - Osteoarthritis. - injury.

  12. Disorders of the Musculoskeletal System Fracture: - Closed fracture. - Open fracture. - Compliocated fracture. - Comminuted fracture. - Impacted fracture. - Incomplete fracture. - Greenstick fracture.

  13. Disorders of the Musculoskeletal System Spinal Disorders: - Scoliosis. - Kyphosis. - Kyphoscoliosis. - Lordosis.
