Symptoms: formation of flat or raised circular area w/ clear central area surrounded by an itchy, scaly, or crusty outer ring
Warts; caused by a viral infection of the skin
Symptoms: rough, hard, elevated, rounded surface on skin; some disappear on their own, others need treatment
Skeletal system
made of organs: bones; adult human has 206 bones;
Functions: framework, protection (vital organs), levers (help provide movement), production of blood cells (red, white, and platelets), storage (calcium)
long part of bone
two ends of the bone
Medullary canal
Cavity in the diaphysis; inner portion of a long bone
Yellow marrow
Soft tissue in the diaphyses of long bones; mainly fat cells
Membrane that lines the medullary canal and keeps the yellow marrow intact; also produces some bone growth
Red marrow
Soft tissue in the epiphyses of long bones; produces red blood cells (erythrocytes), platelets, and some white blood cells; it is used to diagnose blood diseases and is sometimes transplanted in people w/ defective immune systems
Fibrous membrane that covers the bones except at joint areas; contains blood vessels, lymph vessels, and osteoblasts (cells that form new bone tissue); it is necessary for bone growth, repair, and nutrition
Axial skeleton
Forms the main trunk of the body and is composed of the skull, spinal column, ribs, and breastbone
Appendicular skeleton
Forms the extremeties and is composed of the shoulder girdle, arm bones, pelvic girdle, and leg bones
Spherical structure that surrounds and protects the brain; made of eight bones: one frontal, two parietal, two temporal, one occipital, one ethmoid, and one sphenoid
"soft spots" allow for enlargement of the skull as brain growth occurs; made of membrane and cartilage and turn into solid bone by about 18 months of age
areas where the cranial bones have joined together
air spaces in bones of the skull that act as resonating chambers for the voice; lined with mucous membranes
Openings in bones that allow nerves and blood vessels to enter or leave the bones
26 bones that make up the spinal column; protect spinal cord and provide support for the head and trunk
Intervertebral disks
pads of cartilage tissue that separate the vertebrae; they act as shock absorbers and permit bending and twisting movements of the vertebral column
also known as costae; there are 12 pairs; attach to thoracic vertebrae on the dorsal surface of the body
True ribs
First seven pairs of ribs; attach directly to the sternum, or breastbone, on the front of the body
False ribs
Next (middle) 5 pairs of ribs; first three pairs of false ribs attach to cartilage of the rib above
Floating ribs
Last two pairs of false ribs; they have no attachment on the front of the body
breastbone; the last bone of the axial skeleton; consists of three parts, manubrium (upper region), body, and xiphoid process (small piece of cartilage at the bottom)

Rheumatoid arthritis
Chronic, inflammatory disease affecting the connective tissues and joints; three times more common in women than in men and usually is between ages 35-45; attacks can cause scar tissue formation and atrophy of bone/muscle tissue
An inflammation of the bursae, small, fluid-filled sacs surrounding the joints; frequently affects the shoulders, elbows, hips, or knees; symptoms include severe pain, limited movement, and fluid accumulation in the joint
A crack or break in a bone; types include greenstick, simple/closed, compound/open, impacted, comminuted, spiral, depressed, colles
Greenstick fracture
The bone is bent and splits, causing a crack or incomplete break; common in children
Simple/closed fracture
Complete break of the bone with no damage to the skin
Compound/open fracture
Bone breaks and ruptures through the skin; creates an increased chance of infection
Impacted fracture
Broken bone ends jam into each other
Comminuted fracture
Bone fragments or splinteers into more than two pieces
Spiral fratures
Bone twists resulting in one or more breaks; common in skiing and skating accients
Depressed fractures

Colle fractures
Breaking and dislocation of the distal radius that causes a characteristic bulge at the wrist; caused by falling on an outstretched hand
Reduction of a fracture
Before a fracture can heal, the bone must be put back into its proper alignment
Closed reduction of a fracture
involves positioning the bone in correct alignment, usually with traction, and applying a cast or splint to maintain position until fracture heals
Open reduction of a fracture
Involves surgical repair of the bone; sometimes special pins, plates, or other devices are surgically implanted to maintain correct position of the bone
When a bone is forcibly displaced from a joint; frequently occurs in shoulders, fingers, knees, and hips; after dislocation is reduced (bone is replaced in the joint), the dislocation is immobilized with a splint, cast, or traction
When a twisting action tears the ligaments at a joint; wrists an ankles are common sites; symptoms include pain, swelling, discoloration, and limited movement
A bone inflammation usually caused by a pathogenic organism; infectious organisms cause formation of an abscess withing bone and accumulation of pus in medullary canal; sumptoms include pain at site, swelling, chills, and fever, antibiotics are used

Ruptured disk
Also called a herniated or slipped disk, occurs when an intervertebral disk (pad of cartilage separating vertebrae) ruptures or protrudes out of place and causes pressure on spinal nerve; can occur anywhere on spinal column; symptoms include severe pain, muscle spasm, impaired movement, and/or numbness
"hunchback"; rounded bowing of the back at the thoracic area
Side-to-side, or lateral, curvature of the spine
"Swayback"; an abnormal inward curvature of the lumbar region; poor posture, structural defects of the vertebrae, malnutrition, and degeneration of vertebrae can all be causes
