Chapter 5 - Skeletal Anatomy Flashcards
Name 2-3 Functions of the Skeletal System
- Support - Provides support by providing a framework that allows upright posture
- Movement - Allows movement by providing a rigid lever system for muscle attachment across joints.
- Protection - Protects vital organs and soft tissues

Name and describe the three Important Synovial Joints
- Hinge Joint - Allows for movement in 1 direction or plane of motion
- Condyloid Joint - Allows for movement in 2 directions or planes of motion
- Ball and Socket Joint - Allows for movement in 3 directions or planes of motion
Define Medial and Lateral
Medial: Closer to the Midline
Lateral: Further away from the midline
Define Supine and Prone
Supine: Stomach is facing up
Prone: Stomach is facing down
Define Plantar and Dorsal Side
Plantar: The bottom base of the foot
Dorsal side: The top of the foot
Define Proximal and Distal
Proximal: The end of the bone or muscle that is closer to the midline
Distal: The end of the bone or muscle that is further from the midline
Define Flexion, Extension, and Hyperextension
- Flexion: The joint angle becomes smaller
- Extension: The joint angle becomes larger
- Hyperextension: Movement that occurs beyond the range of motion (ROM)
Name 3-4 bones of each Skeleton - Axial and Appendicular
Axial - Skull, Thorax, and Vertebrael Colum
Appendicular - Tibia, Fibula, Ulna, Radius, Femur, and Humerus
What three systems control the Spinal Stabilization system?
- Control Subsystem
- Passive Subsystem
- Active Subsystem
