Study Guide Flashcards
Kinetic Chain
Interrelation of nervous, muscular, and skeletal systems to create movement
Central Nervous System (CNS)
Brain and Spinal Cord; coordinates activity of all body parts
Peripheral Nervous System (PNS)
all nerves branching off spinal cord, extending out to the body
Mechanoreceptors
sense distortion in the body tissues
. golgi tendon organs (GTO): sense changes in tension
. muscle spindles: sense changes in length
Propriception
cumulative sensory input to the CNS from all mechanoreceptors
Stabilization Muscles of the Core
- Transverse abdominis
- Multifidus
- Internal and external obliques
- Diaphragm
- Pelvic floor muscles
- Rotator cuff
- Quadratus lumborum
- Psoas major
- Rectus abdominis
- Gluteus medius
- Adductor complex (inner thighs)
Movement Muscles of the Core
- Latissimus dorsi
- Hip flexors
- Hamstring complex
- Quadriceps
- Pectoralis major
- Deltoids
- Gluteus maximus
- Triceps
- Biceps
- Erector spinae
Tendons
- connect muscle to bone
- the anchor to produce force
- limited blood flow
- slow to repair
Sarcomeres
individual contractile units; actin and myosin filaments
Type I (SLOW TWITCH MUSCLE TISSUE)
- more aerobic
- slower to reach maximal contraction
- resistant to fatigue
Type II (FAST TWITCH) Muscle Tissue
- more anaerobic
- produce more speed and strength
- faster to fatigue
Behavioral properties of muscle
- extensibility
- elasticity
- irritability
- ability to develop tension
Ligaments
- connect bone to bone
- limited blood flow
- slow to repair
Axial Skeleton
- skull
- ribcage
- vertebral column
Appendicular column
bones of upper and lower extremities
