Abb’s & word part review

Skeletal Vocab: for the words below in the square do # 1 & using the word parts chart, try to define those vocab terms Skeletal articulation Axial Bursa cartilage Degeneration Periosteum Prosthesis synovial

Vocab activity: no notes Using the mix and match at your lab station match the word and definition. We will correct as class Then fill in your vocab chart ADD to the definition that you have already done from the prior activity Skeletal: pertaining to the skeleton

Review!

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

Shapes of Bones  Long: femur, humerus, tibia, fibula  Short: small cubed-shaped: carpals, tarsals, toes  Flat: usually cover organs: scapula, pelvis, skull,ribs  Irregular: 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
