Ortho A&P 2


Fascicles combine into: muscle body
Slow twitch (type I) muscle Oxidative; Aerobic; Endurance
Fast twitch (type II) muscle Glycolytic (ATP system); Anaerobic; Speed/ Strength
Muscle Action: stimulus in neuron: carried down axon to neuromuscular junction
At NMJ: ACTH released from pre-synaptic vesicles & diffuses across synapse to receptor on muscle
Muscle Action: binding at receptor triggers: depolarization, releasing Ca
Muscle Action: Calcium binds: troponin
Muscle Action: troponin is bound; then: Actin-myosin cross bridges form; muscle contracts
Tendon: Attaches mx to bone; transfers mx action to bone; enclosed within a tendon sheath
Ligament: Attaches bone to bone; provides stability to the joint
