Study Notes
Skeletal System Functions
- The skeletal system provides framework for the body, stores minerals, helps with movement, produces blood cells, and supports/protects organs.
Types of Fractures
- A greenstick fracture is a broken bone in children where the bone only partially breaks.
- An oblique fracture is a diagonal fracture.
- A compression fracture is when the bone is pressed together and breaks.
- A spiral fracture winds around the bone.
Joint Terminology
- A joint is a place where two bones meet.
- A ligament connects bone to bone.
- A tendon connects muscle to bone.
- Crepitation is a cracking sensation felt and heard upon movement of a joint.
- A luxation is a dislocation.
- A bursa is a fibrous sac that acts as a cushion to allow for smooth movement.
Bone Parts and Locations
- The diaphysis is the shaft of a long bone.
- The epiphysis is the wide knob-like end of a bone covered with cartilage.
- The metaphysis is the area where the diaphysis and epiphysis meet.
- The periosteum is the tough, outer membrane covering of bone.
- Yellow bone marrow is found in the medullary cavity, which is a hollow space in the shaft of long bones.
Bone Cell Types
- Osteoblasts form bone.
Other Bone Conditions
- Rickets is a childhood disease caused by a lack of Vitamin D that causes bone deformities.
Types of Joints
- A ball and socket joint allows for a large range of motion.
- A gliding joint allows for side to side movement.
- A symphysis is a joint where two bones are joined together by cartilage, and they function as one bone.
Bone Conditions
- Osteoarthritis is arthritis due to normal wear and tear of the aging process.
- Gout is a disease process where uric acid crystals form in joints.
- Bursitis is inflammation of the bursa.
- Scoliosis is another name for a crooked spine, resulting in a lateral curvature.
- Lordosis is another name for swayback.
- Myeloma is a malignant tumor of blood-forming cells in bone marrow.
- Talipes is another name for club foot.
Types of Fracture Treatment
- Internal fixation is when pins and/or plates are placed directly into the bone to repair a fracture.
- External fixation utilizes pins and other outer appliances applied through the skin into the soft tissues to repair a fracture.
Other Skeletal System Terms
- A fontanelle is another name for the soft spot found on newborns.
- A foramen is an opening in a bone.
- Arthralgia is joint pain.
- Arthroscopy is a direct visual exam of a joint.
Skeletal System Counts
