Skeletal Outline
Function of Bones
• Provide shape and support
• Protection of internal organs
• Storing minerals and fat
• Producing blood cells and platelets
• Assisting with movement
Bone Tissue
• Composed of: inorganic salts (calcium), bone cells, blood vessels,
nerves, collagen
• Needs food and oxygen
• Continue to grow throughout life, replacing damaged bone
Components of Bone
• Osteoblasts (build up bone)
• Osteoclasts (clean up bone and debris)
• Cartilage
• Aponeurosis
• Dense (compact bone)
• Spongy (cancelous bone)
Skeletal System
1.
Axial = 80 bones
= 126 bones
Shapes of Bones
 Long:
femur, humerus, tibia, fibula
 Short:
small cubed-shaped: carpals, tarsals, toes
 Flat: usually
 Irregular:
cover organs: scapula, pelvis, skull,ribs
bones of ear, vertebrae, bones of face
 Sesamoid: patella
(knee cap)
Review: name the type of bone
Skull
• Cranium = 8 bones
• Face = 14 bones
• Ears
• Mandible is the only movable part of the skull
Thorax
• Ribs
• True ribs: first 7
• False ribs: lower 5 ( last 2 are called floating ribs)
• Intercostal space: contains muscles, blood vessels, nerves
• Sternum
• Vertebral bones = 26 bones
true
false
Articulations (joints)
• Joints are named by the bones they join
• Synarthrosis (immovable): cranial bones
• Amphiarthrosis (slightly movable): ribs connected to sternum
• Diarthrosis (freely movable, synovial)
• Synovial joints contain a bursa: fluid filled sac
6 types of Diarthrosis(movable) Joints
1.
Ball and socket: shoulder, hip
2.
Hinge: elbow, ankle, knee
3.
Gliding: in between the carpal bones
4.
Pivot: Radius on ulna
5.
Saddle: Thumb (thumb touching finger tips)
6.
Gomphosis: (teeth)
Examples of Diarthrodial (moveable) joints
Name the Joints
Health Concerns
• Gout:
• Eti: Painful swelling of a joint that results in uric acid build up.
Mostly in great toe
• S/S: fever, chills, complications from another disorder.
• TX: medications, diet therapy
• Dislocation:
• Eti: Bone has moved out of place. Congenital or from trauma
• S/S: pain, loss of function, deformity
• TX: relocate, surgery
• Kyphosis:
•
•
•
•
abnormal curvature of the thoracic spine. “Hunchback”
Eti: Rheumatic arthritis, rickets, poor posture, chronic respiratory disease
S/S: pain because of nerves are affected
TX: exercises to strengthen back
• Scoliosis:
•
•
•
•
Abnormal lateral curvature of the spine.
Eti: may be congenital, rickets, or shortening of one leg.
S/S: Discomfort in walking, low back pain, shoulder is higher
TX: corrective exercises, braces, casting, surgical correction
• Lordosis:
•
•
•
•
Abnormal curvature of lumbar spine “swayback”
Eti: pregnancy, obesity, poor posture
S/S: low back pain
TX: Exercise, brace
• Bursitis
•
•
•
•
Inflammation of the sac around a joint
Eti: Caused by trauma or irritation
S/S: swelling, restricted movement
TX: protection of joint, rest, medication, removal of excess fluid
• Arthritis:
•
•
•
•
Inflammation of a joint. #1 crippling disease
Eti: joint disease, infection, gout
S/S: pain and stiffness while moving
TX: no cure. Treatment to relieve pain. Surgery in sever cases to replace joint
• Osteoporosis:
• Eti: abnormal softening of the bones due to lack of calcium
• S/S: loss of bone density, easily broken bones
• TX: women should take hormones, calcium, vitamin D
• Spiral fx
• Colles fx
• Greenstick fx
