Muscle Action

A change in the body or a bodily organ as a result of its functioning is referred to as an action. Muscle action can be defined as the specific movement of a bodily part generated by the contraction of a muscle. The muscle proteins actin and myosin are the important contractile proteins involved in muscle action. Muscle contraction, in addition to movement, serves several other important functions in the body, including posture, heat generation, and joint stability. Muscle contraction maintains posture, which includes standing and sitting.

You're hiking, you step on a piece of wood and a protruding rusty nail goes right through your Puma Cydes and into your foot. You start thinking....when was my last tetanus booster shot??? We're not talking about tetanus as defined in our studies of muscle physiology, but pathological tetanus (also known as "lockjaw"). In this condition, bacteria called Clostridia tetani (found in dirt) enter the bloodstream and grow, producing tetanus neurotoxin. The result of this toxin coursing through your bloodstream is causes the prime mover and its antagonist muscle groups (doesn't just have to be muscles of the jaw) to contract at the same time. How does the neurotoxin do that? Knowing all this, and being experts on Human reflex Physiology, do you think your reflexes (like the knee-jerk) would still function if you were suffering from "lock-jaw?"
