1 The Skeletal System Medical Terminology

2 Key System Terminology Bone oste/o Bone marrow myel/o »Note myel/o also means spine Joints arthr/o Cartilage chondr/o Bursa burs/o

3 –Diaphysis Medullary cavity –Yellow marrow –Epiphysis Red marrow –Compact bone Lamellar bone –Spongy bone Trabecular bone –Periosteum –Endosteum –Articular cartilage –Epiphyseal plate –Ligament – connects bone to bone Tendon Bone Anatomy

4 Axial skeleton –80 bones –Skull –Spine –Thoracic cage Appendicular skeleton –126 bones –Shoulder girdle + arm –Hip girdle + leg 206 bones

5 Cranium –Frontal –Parietal –Occipital –Temporal –Sphenoid –Ethmoid Face –Zygomatic –Maxillary –Mandible –Palatine –Lacrimal –Vomer –Hyoid Bone

6 Ribs (rib = costal) [12 pairs] True (7) False (3) Floating (2) Sternum –Manubrium –Body –Xiphoid Shoulder –Clavicle –Scapula Acromion Process Arm –Humerus –Radius –Ulna ( & olecranon process) Wrist & Hand –Carpals –Metacarpals –Phalanges

7 Spine –Vertebrae Cervical (7) Thoracic (12) Lumbar (5) Sacrum (5) Coccyx (4) –Intervertebral Discs Pelvic Girdle (hip/ Coxa) –Ilium –Ischium –Pubis –Sacrum –Acetabulum

8 Legs –Femur –Patella –Tibia –Fibula Ankle & Foot –Tarsals Talus Calcaneus Lateral & Medial Malleolus –Metatarsals –Phalanges

9 Skeletal System Structures in Medical Terminology Oste/o = bone Chondr/o = cartilage Arthr/o = joints Myel/o = bone marrow »Note: also can mean spine Burs/o = bursa Cost/o = rib

10 Joints (Articulations) Functional classification based upon movement: –immovable = synarthrosis –slightly movable = amphiarthrosis –freely movable = diarthrosis Most are diarthrosis –Also called synovial joints Joints Synovial Membrane Synovial Fluid Bursa Articulations Ligaments (compare to tendons)

11 Bursa –A sac made up of: Synovial membrane Synovial fluid

12 Medical Specialists of the Skeletal System Orthopedist –Those with a medical school degree –Those with a osteopathic school degree Chiropracter –All diseases center around spinal mal-alignment Podiatrist Orthotics

13 Ankylosis (ankyl/o = stiff; bent) Arthralgia Arthrosclerosis Bursitis Chondroma Chondromalacia (-malacia= abnormal softening) Hallux valgus (bunion; big toe bent towards other toes) Luxation Synovitis Arthritis Osteoarthritis Rheumatoid arthritis Ankylosing Spondylitis (spondyl = vertebrae) –This is a type of rheumatoid arthritis Talipes (club foot) Pathology of the Skeletal System

14 Spine Herniated disc Lumbago Spina bifida Kyphosis Lordosis Scoliosis

15 Scoliosis Kyphosis Lordosis

16 Bone Exostosis (callus) Osteomalacia Osteitis deformans Periostitis Osteochondroma Osteoporosis Fractures Closed (simple) Open (compound) Colles’ Pathology of the Skeletal System
