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
Produces synovial fluid; has joint cavity and connective tissue.
Synovial Joint
No axis of rotation; slides side-to-side, back and forth. Example: Carpals of the hand
Gliding Joint
Unaxial; one plane of motion. Example: Elbow
Hinge Joint
Condyles of one bone fit ellipitcal cavities of another; one plane of motion. Example: Knee
Condyloid Joint
One bone fits like a saddle on another; two planes of motion (sagittal, frontal). Example: Thumb
Saddle Joint
One axis; transverse plane movement. Example: Radioulnar
Pivot Joint
Most mobile; all three planes motion. Example: Shoulder
Ball-and-Socket Joint
