If you know that wrinkles are caused by muscle contractions around the eye, and you know the effect of Botox on acetylcholine release (CQ3) and, therefore, muscle contraction (CQ4), what is the effect of Botox on wrinkles? A. Induces wrinkles by inducing acetylcholine release, and, therefore, contraction of muscles around the eye. B. Inhibits wrinkles by preventing acetylcholine release, and, therefore, preventing contraction of muscles around the eye.

Choose any and all appropriate answers: How is the muscular contraction stopped (i.e.: how does a muscle relax after contraction)? The brain stops sending the nerve impulse that commands the muscle to contract, interrupting communication at the neuromuscular junction Acetylcholineesterase (AChE) is released into the synaptic cleft to destroy any remaining Acetylcholine No mechanism is necessary. When the antagonist begins to contract, it forces relaxation and stretch of the agonist muscle. Relaxation occurs as the myosin heads are "snapped" off...

draw a short comic that illustrates the steps of muscle contraction (including stimulus for contraction, excitation-contraction coupling, contraction, cross bridge cycling, and relaxation). Your finished drawing should have a minimum of 7 “panels” - one for each step of muscle contraction listed above, and one each for the establishment and the conclusion of the story you are telling. All chemical and structural participants in this complex interaction should be accounted for. All components of your comic should be labelled (which...

Which of the following statements about skeletal muscle contraction is false? During muscle contraction, the Z discs move closer together as the myosin heads move toward the plus ends of the actin filaments. The changes in voltage across the plasma membrane that occur when a muscle cell receives a signal from the nervous system causes Ca2+ to flow into the sarcoplasmic reticulum, triggering a muscle contraction. An action potential in the muscle cell plasma membrane leads to voltage-gated calcium channels...
