Musculoskeletal System Review Session 1 (via Scorebuilders) Flashcards
What are the 3 energy systems in the human body?
- ATP-PC/ Phosphagen Energy System
- Anaerobic Glycolysis/ Lactic Acid System
- Aerobic/ Oxygen System
This type of energy system is utilized during high intensity, short duration bursts (i.e. 100 m sprint). This system provides energy for muscle contraction up to 15s. It does not depend on transporting oxygen for energy.
ATP-PC/ Phosphagen Energy System
This system only uses carbohydrates and is utilized during high intensity, short duration activities (i.e. 400m or 800m sprint). This process allows 30 to 40s of a muscular contraction. It does not require the presence of oxygen.
Anaerobic Glycolysis/ Lactic Acid System
This type of energy system is used in low intensity, long duration exercise such as running a marathon. This system yields the most ATP, but requires a complex series of chemical reactions. This system provides energy through the oxidation of food.
Aerobic/ Oxygen System
Describe the classes of levers (fulcrum [axis of rotation], load [resistance], and effort [force]) and provide an anatomical example for each.
- Class 1: Fulcrum is between the load and the effort. Ex: Triceps brachii and Atlanto-occipital joint
- Class 2: Load is between the fulcrum and the effort (think wheelbarrow) Ex: Plantarflexion, push-up
- Class 3: Effort is between the load and the fulcrum. Ex: biceps brachii, biceps femoris
What are the types of joint classifications? Be able to provide examples for each.
- Fibrous Joints (Synarthroses). 3 types: Sutures (skull), Syndesmosis (interosseous membrane of tib-fib), and gomphoses (tooth in socket). No movement.
- Cartilaginous Joints (Amphiarthroses). 2 types: Synchondrosis (sternum) and Symphysis (pubic symphysis). Slight movement.
- Synovial Joints (Diarthroses). 3 types: Uniaxial (hinge [elbow], pivot [AA]), Biaxial (condyloid [MCP], saddle [CMC], and Multiaxial (plane [carpal joints], ball and socket [hip])
Name the common Joint Receptors and briefly describe their functions.
- Free Nerve Endings - mechanical stress and noxious stimuli
- Pacinian Corpuscles - vibration, acceleration, and high velocity changes
- Golgi Ligament Endings - tension or stretch on ligaments
- Ruffini Endings - stretching of joint capsule; amplitude and velocity of joint position
- Golgi - Mazzoni Corpuscles - compression of joint capsule
