Transcript of BUS180: Bones Presentation
Orfa Functions framework of the body
supports and protects internal organs
helps with body movement
storage of minerals
production of red bone marrow Word Parts Ankyl/o
Oss/e, oss/i, ost/o, oste/o
-um Crooked, bent, stiff
To bind tie together
Curve, sway back, bent
Loosening or setting free
Vertebrae, vertebral column, backbone
Singular noun ending How it "fits in" with the rest of the System Axial Skeleton: protects major organs of the nervous,
respiratory, and circulatory system. Appendicular Skeleton: makes body movement possible and protects organs of digestion, excretion, and reproduction Major functions of the bone: Curvature of the Spine -osis means abnormal condition/disease
Kyphosis (kyph- means hump)
Lordosis (lord- means bent back)
Scoliosis (scoli- means curved) Diseases Craniostenosis
crani/o means skull
-stenosis means abnormal narrowing
Malformation of the skull due to the premature closure of the cranial sutures. Fibrous Dysplasia
dys means difficult,
plasia means formation
Is a bone disorder of unknown cause that destroys normal bone structure and replaces it with fibrous (scarlike) tissue. This leads to uneven growth and brittlesness, and deformity of the affected bones. Bone Tumors Primary bone cancer: relatively rare malignant tumor that originates in a bone Bone Repair Bone fracture repair is surgery to fix a broken bone using plates, nails, screws, or pins. Bone grafts may be used to allow for proper healing or to assist in the healing process. Secondary bone cancer: describes tumors that have metastasized to bones from other organs such as the breasts and lungs Diagnostic Procedures Radiographs (x-rays)
-scopy: visual examination Bone Prevention CARDIOVASCULAR ENDURANCE EXERCISE- Serves the additional purpose of building muscle strength, which will help keep you upright and free from fracture-inducing falls. WEIGHT TRAINING- Will build bone density. SIX VITAMINS AND NUTRIENTS FOR STRONG BONES- Calcium, Magnesium, Vitamin D, Potassium, Vitamin K, and Vitamin B12. Adding these six important vitamins and nutrients to your diet is an important step towards building bones that will last a lifetime. THROW OUT YOUR CIGARETTES- Nicotine and free radicals may harm your body's bone-making cells known as osteoblasts. DON'T BREAK A LEG (OR AN ARM)- Preventing falls is key for warding off broken bones. Practice home safety measures and stay away from dangerous stunts. Magnetic Resonance Imaging (MRI)
Bone Marrow Biopsy
Bone Scans Osteoporosis
oste/o means bones
por means small opening
-osis means abnormal condition or disease
Is a marked loss of bone density and an incrase in bone porosity that frequently associated with aging. Osteomalacia
Oste/o means bone
-malacia means abnormal softening)
This condition is usually caused by deficiency of vitamin D, Calcium and/or phosphate. Bone Repair Bone fracture healing is a complex process with four steps. All bone fractures must go through this process. Step 1: Inflammation. When a bone fractures, white blood cells move in to the area to clean up debris created by the break. This creates inflammation, which triggers the growth of new blood cells — the first stage of healing. Step 2: Soft callus. As blood cells divide and multiply near the break, new blood vessels develop to fuel the repair process. The body also begins to create cartilage around the bone fracture to bridge the gap in the bone. Called the soft callus, this cartilage is simply fibrous tissue. Step 3: Hard callus. Eventually, the body replaces the soft callus with a hard callus, connecting the bone fragments more solidly. This stronger callus, which creates a bulge at the site of the fracture, can generally be seen in X-rays just a few weeks after the bone fracture occurs. Step 4: Remodeling. In the final stage of bone fracture healing, the body replaces old bone with new bone in a continual process called remodeling. Remodeling makes bones stronger and more compact and blood circulation in the bone improves.
