What is the composition of bone?
*Formed of Connective Tissue(2nd strongest)(1st strongest is enamel).
-can regenerate it self(fx).
-6-8 weeks to heal depending on the type of patient, Fx and bone affected.
*Compact bone(bone density) peak bone mass is at age 30 yrs.
-hemopoetic(forms blood cells).
*Spongy bone(red bone marrow).
*Smooth, rubbery, blue-white connective tissue(2nd hardest).
*Acts as a shock absorber between the bones(shoulder, elbow,wrist).
*Meniscus is curved fibrous cartilage found in the knee and jaw.
shaft of a long bone(femur).
wide end of a long bone(humerus).
end of the bone located closest to the midline.
end of the bone located furthest away from the midline.
little boney bump begining to end.
: red bone marrow.
Lighter and less strong then compact bone.
Yellow Bone Marrow
fat storage, composed of fat cells.
located in Medullary Cavity.
*Ball and socket joints(hip and shoulders).
-ROM is greater.
*Hinge joints(knee, elbow).
-ROM is limited.
Joint (articulations) are connections between bones.
Suture-immovable joint allows for growth(25yrs).
Fontanelles- newborn soft spot of head or brain(1st yr of growth).
Diffrence between fontanelles and sutures?
child matures the sutures (no movement)close together and the fontanelles(flexable) harden.
1st 7 pairs are true ribs(14).
2nd 3 pairs are false ribs(6).
final 2 pairs are floating ribs(4).
attached to sternum.
average adult 1/3 of height (19in)(48cm).
largest and sttrongest bone of body.
capable of supporting multiple times a person's body weight.
a opening in a bone through which blood vessels,nerves, ligaments pass(plural, foramina).
example the spinal cord passes thru foramen magnum of the occipital bone.
shorter bone of the forarm(located on the thumb side).
Bones of the arm
humerus (bone of upper arm).
radius(short bone of forarm, thumb side).
ulna (longer bone of the forarm articulates with the humerus to form the elbow joint; fifth digit side).
six tiny bones in middle ear.
forms the posterior floor and walls of the cranium(C).
Cranial and facial bones
Vertebral column(spinal column)
supports head and protects spinal cord.
31 pairs of spinal nerves(cervical to sacrum).
forms the outward curve of the spine.
kyphosis is common inthis region of the spine.
an abnormal increase in the outward curvature of the thoracic spine as viewed from the side.
Kyph means hump.
-osis means abnormal condition.(humpback,dowager's hump).
the surgical repair of damaged cartilage
L1-L5 make up the third set of five vertebrae
forms the inward curve of spine.
largest and strongest of vertebrae.
common site for back injury or pain.
obesity, pregnancy, osteoporosis,MVA, poor ergonomics, and sports related injuries.
three small bones found in middle ear.
transmits sound wave from eardrum to inner ear by vibration.
is a inflammation of the bone marrow and adjacent bone.
bacterial infection originates from another part of body and spreads to bone through blood.
: means bone.
: bone marrow.
axis(c2) mobility, rotation.
aka funny bone, is a large projection on the upper end of the ulna.
point of elbow exposes a nerve that tingles when struck.
attach posteriorly to the thoracic vertebrae.
: pertaining to.
aka heel bone.
the largest tarsal bones.
the ankle bone and articulates with the tibia/fibula.
the rounded bony protrusion on each side of the ankle.
Wilhelm Conrad Rontgen
-march 27, 1845 - feb 10, 1923.
-father of diagnostic radiology
: medical speciality which uses imaging to diagnose disease.
-discoverd the X Ray in November 8, 1895
humira & enbrel (injectables)
treatment and medications for rheumatoid arthritis.
secretes synovial fluid.
synovial fluid lubricates the joints for movement.
bursa cushions to minimize friction in shoulders, elbows, and knees.
structures of vertebra
body( anterior portion).
vertebral foramen(spinal cord passes thru opening).
inflammation of one or two joints.
(RA) Rheumatoid arthritis
: synovial membranes become inflamed.
RA more common in women then men, occurs between ages 40-60.
RA sign and symptoms
joint pain and damage.(12 months)
red and puffy hands.
effects small joints first(wrist, hands, ankles, feet)
rheumatoid arthritis cause? (genetics)
immune system attacts the synovium, the lining of the membranes that surround the joints.
imflammtion thickens the synovium, invade and destroy the cartilage and bone within the joint.
osteoporosis loss of bone density and increase in porosity(porses)
weakens bones, increase risk of fractions.
most common bone disease.
spinal compression go undiagnosed, patients think its back pain or arthritis
