Describe the different systems within skeletal muscle that provide skeletal muscle with ATP. In your answer include, substrates used, products produced, duration that the system lasts, and their associated contributions to muscle fibre type.

Based on what you know about the neuromuscular junction and muscle contraction, describe very specifically how Botox injections cause localized muscle weakness/paralysis.

Describe the position where wrist and finger are in full extension.  What sensation will be felt in this position? What explains this sensation that you felt when the wrist and fingers were positioned in extension? *NOTE: Apply any of the following concepts to the explanation as deemed appropriate and connected to the situation above: Mucle Contraction, Concentric Contraction, Isometric Contraction, Eccentric Contraction, Force Velocity Curve, Stretch Reflex, Reciprocal Inhibition, Autogenic Inhibition, Length-Tension Relationship

Muscle fatigue occurs because of..  A relative deficit of ATP  Excessive accumulation of lactic acid  Ionic imbalances  Depletion of nutient stores  All of the above
