  1. The body's framework, composed of bones and joints
    skeletal System
  2. Provide a resting ground for muscles and protection of vital organs
    Bones
  3. Junctions of bones, muscles, and connective tissue at which movement occurs.  Also know as an articulaion
    Joints
  4. Portion of the skeletal system that consists of the skull, reb cage, and vertebral column
    Axial Skeleton
  5. Portion of the skeletal system that includes the upper and lower extremities.
    Appendicular Skeleton
  6. The process of resorption and formation of bone
    Remodeling
  7. A type of bone cell that removes none tissue
    Osteoclasts
  8. A type of cell that is responsible for bone formation
    Osteoblasts
  9. Type of Bone: long, cylindrical shaft and irregular or widened ends
    long
  10. Type of Bone: similar in length and width and appear somewhat cubical in shape, carpals of hand, tarsals of feet
    short
  11. Type of bone: thin, protective. Example: scapulae
    flat
  12. Type of Bone: Unique shape and function.  Example: vertebrae
    irregular
  13. Type of Bone: Small often round bones embedded in a joint capsule or found in locations where a tendon passes over a joint. Example: Patella
    sesamoid
  14. The end of long bones, which is mainly composed of cancellous bone, and house much of the red marrow involved in red blood cell production.  They are also one of the primary sites for bone growth
    Epiphysis
  15. The shaft portion of a long bone
    Diaphysis
  16. The region of long bone connecting the diaphysis to the epiphysis.  It is a layer of subdividing cartilaginous cells in which growth in length of the diaphysis occurs
    Epiphyseal Plate
  17. A dense membrane composed of fibrous connective tissue that closely wraps (invests) all bone, except that of the articulation surfaces in joints, which are covered by a synovial membrane
    Periosteum
  18. The central cavity of bone shafts where marrow is stored
    Medullar cavity
  19. Cartilage that covers the articular surfaces of bones
    Articular (Hyaline) Cartilage
  20. Flattened or indented portions of bone, which can be muscle attachment sites
    Depressions
  21. Projections protruding from the bone where muscles, tendons, and ligaments can attach
    Processes
  22. A series of irregularly shaped bones called vertebrae that houses the spinal cord
    Vertebral Column
  23. First seven vertebrae starting at the top of the spinal column
    Cervical spine
  24. Twelve vertebrae located in the upper/middle back behind the ribs
    Thoracic spine
  25. Five vertebrae of the low back below the thoracic spine
    Lumbar spine
  26. triangular bone located below the lumbar spine
    Sacrum
  27. Located below the sacrum, more commonly know as the tailbone
    Coccyx
  28. Joint motion
    Arthrokinematics
  29. Joints that are held together by a joint capsule and ligaments and are most associated with movement in the body
    Synovial Joints
  30. Joints that do not have a joint cavity, connective tissue or cartilage
    Nonsynovial
  31. Joint type: No axis of rotation; moves by sliding side-to-side or back and forth. Example: carpals of the hand
    Gliding
  32. Joint type: Formed by the fitting of condyles of one bone into elliptical cavities of another; moves predominantly in one plane.  Example: Knee
    Condyloid
  33. Type of joint: Uniaxial; moves predominantly in one plane of motion (sagittal)
    Hinge
  34. One bone fits like a saddle on another bone; moves predominantly in two planes.  Only the thumb
    Saddle
  35. type of joint: Only one axis; moves predominantly in one plane of motion (transverse). Example: radioulnar
    Pivot
  36. Most mobile of joint; moves in all three planes of motion. Example: Shoulder
    Ball-and-socket
  37. Primary connective tissue that connects bones together and provides stability, input to the nervous system, guidance, and the limitation of improper joint movement
    Ligament
