Skeletal System Flashcards
Ball-and-socket
Shoulders, hips; most mobile, all three planes of motion
Weight bearing exercise
The best method to strengthen bones
Process
Projection protruding from a bone; muscles, tendons, and ligaments can attach
Arthrokinematics
Joint motion
Depressions
Flattened or indented portions of a bone; can be muscle attachment sites
Major motion types
Roll, slide, and spin
Synovial joints
Held together by joint capsule and ligaments; greatest capacity for motion
Hinge
Elbows, ankles; sagittal plane movement
Appendicular skeleton
Upper and lower extremities, shoulder and pelvic girdles
Ligaments
Connects bone to bone; little blood supply; slow to heal
Non-synovial joins
No joint cavity, connective tissue, or cartilage; little to no movement
Skeletal system functions
Supports, protects, allows bodily movement
Axial skeleton
Skull, rib cage, and vertebral column
