The Human Movement System (Nervous, Muscular, Skeletal, Breakdown of Joints) Flashcards
Brain and spinal cord, extending out to the body.
Central Nervous System (CNS)
All nerves branching off spinal cord, extending out to the body
Peripheral Nervous System (PNS)
Sense changes in tension.
Golgi Tendon Organs (GTO)
Sense changes in length.
Muscle Spindle
What are the stabilization muscles of the core?
- Transverse Abdominis
- Multifidus
- Internal Obliques
- Diaphragm
- Pelvic Floor Muscles
- Rotator Cuff
- External Obliques
- Quadratus Lumborum
- Psoas Major
- Rectus Abdominis
- Gluteus Medius
- Adductor Complex
What are the movement muscles of the core?
- Latissimus Dorsi
- Hip Flexors
- Hamstring Complex
- Quadriceps
- Pectoralis Major
- Deltoids
- Gluteus Maximus
- Triceps
- Biceps
- Erector Spinae
Connect muscle to bone; anchor to produce force; limited blood flow, slow to repair.
Tendons
Individual contractile units; actin and myosin filaments.
Sarcomeres
More aerobic; slower to reach maximal contraction; resistant to fatigue.
Type I (Slow Twitch) Muscle Tissue
More anaerobic; produce more speed and strength; faster to fatigue.
Type II (Fast Twitch) Muscle Tissue
What are the behavioral properties of muscle?
Extensibility, Elasticity, Irritability, Ability to develop tension
Connect bone to bone; limited blood flow; slow to repair.
Ligaments
Skull, rib cage, and vertebral column
Axial Skeleton
What are the skeletal system functions?
Movement, Support, Protection, Blood Protection, Mineral Storage.
No joint cavity or connective tissue; little to no movement. Example: Sutures of the skull
Non-Synovial Joint
