Bones
- primary organs of skeletal system, composed of 50% water and 50% osseous tissue
- provide framework and support for body and protection for internal organs
Cartilage
Major portion of embryonic skeleton and part of adult skeleton
Tendons
Attach muscles to bones
Ligaments
Connect bones, cartilages, and other structures
How many bones in the skeletal system?
206
Osteoblasts
Bone forming cells
Endochondral ossification
Cartilage breaks down and is replaced by osteoblasts in second month of life
Flat bones
Ribs, scapula, skull bones
Long bones
Femur, tibia, humerus, radius
Short bones
Carpals and tarsals
Irregular
Vertebrae, ossicles of ear
Sesamoid
Patella
Wormian
Sutural; between bones of the skull
Epiphysis
Ends of a developing bone
Diaphysis
Shaft of a long bone
Periosteum
Fibrous vascular membrane that forms covering of bones
Compact bone
Aka cortical bone, dense and hard layer of bone tissue
Medullary canal
Narrow space of cavity throughout bone length
Spongy bone
Aka cancellous bone, reticular network that makes up most of the volume
Joint
Articulation, place where two or moe bones connect
Osteoarthritis
Years of wear and tear; synovial fluid loses ability to lubricate and bones rub together and break down cartilage. Suffer mostly at night because they are on it all day
Rheumatoid arthritis
Autoimmune disease where the cells in the synovial lining replicate and cause inflammation which leads to destruction of surrounding structures
Synarthrosis joint
Aka fibrous joint, does not permit movement
Ex) cranial suture
Amphiarthrosis joint
Aka cartilaginous joint, very slight movement
Ex) vertebrae
Diarthrosis joint
Aka synovial joint, free range of movement
Ex) hip, knee, elbow, wrist
Abduction
Moving away from the middle
Adduction
Moving toward the middle
Circumduction
Moving a body part in a circular motion
Dorsiflexion
Bending a body part backward
Eversion
Turning outward
Inversion
Turning inward
Flexion
Bending a limb
Extension
Straightening a flexed limb
Pronation
Turning downward
Supination
Turning upward
4 sections of vertebral column
Cervical-7
Thoracic-12
Lumbar-5
Sacral-sacrum and coccyx
Closed, or simple fracture
Internal break that does not puncture the skin
Open or compound fracture
Fracture punctures the skin
Transverse fracture
Broken straight across the bone
Comminuted
Broken into more than one piece
Greenstick fracture
One side of the shaft is broken and the other is bent
Colles fracture
Break in distal portion of radius (near the wrist) and usually occurs when reaching out to cushion a fall
Compression fracture
Due to the collapse of a vertebra
Vertebral compression
Severe band-like pain resulting from compression fractures. Repeated compression fractures can lead to chronic lower back pain or spine curvature
Epiphyseal fracture
Occurs in epiphyseal growth plate in children
Stress fracture
Occurs during the course of normal activity
Ex) patients with osteoporosis develop stress fractures of the feet stepping off a curb
Hip fracture
Usually occurs as a result of a fall or osteoporosis
Kyphosis
Thoracic curvature becomes exaggerated producing “humpback”
Lordosis
Anterior curvature of lumbar spine(belly protrudes), “swayback”
Scoliosis
Abnormal lateral curvature of the spine
Anti-inflammatory agents
Steroidal (corticosteroids) and nonsteroidal. Relieves symptoms of inflammation.
Ex) prednisone
Disease-modifying antirheumatic drugs (DMARDs)
Ridaura and plaquenil
COX-2 Inhibitors
Celebrex, mobic
Antitumor Necrosis Factor (Anti-TNF) Drugs
Enbrel
Gout treating agents
Zyloprim
Postmenopausal osteoporosis drugs
- antiresorptive agents decrease removal of calcium from bones-Boniva
- estrogen hormone therapy-Premarin
Analgesics
Relieve pain, narcotic or non-narcotic
Narcotic-Demerol and Percocet
Non-narcotic- Tylenol, aspirin, ibuprofen
Arthrography
Diagnostic examination of a joint where a radiopaque contrast medium is injected
Arthroscopy
Examining internal structures of a joint via arthroscope
Arthroscope
