Neurons are the basic building blocks of the nervous system.

In a classic experiment, the strength of a neural stimulus and the resulting muscle contraction are compared. A single motor neuron that sends a message to a muscle fibre is suspended. One end is attached to the muscle fibre, and the free end of the muscle fibre is attached to a mass. If an electrical stimulus is sufficient to cause an impulse in the neuron, the muscle will contract and lift the mass. The following data were obtained from the experiment.

A study of muscle fibers between chimpanzees and humans revealed that although muscle mass per body size are approximately equivalent, the ratio of red (slow) and white (fast) fibers were significantly different. Chimps tend to have a ratio of 30% red to 70% white where humans are 60/40 respectively. Speculate about what this ratio difference means in terms of muscle activity potential and a possible evolutionary significance of this difference.
What methods can you use to test if someone has more fast twitch versus slow twitch muscle fibers? Remember the variances between fast twitch and slow twitch muscle fibers. Based on this, select a sport and a muscle group primarily used for that sport. Then share which muscle fiber type would be highest for that muscle group.

Succinylcholine act as adepolarising agent that prevents repolarization of the somatic motor neuron. Thus, no further ACh is released until drug is cleared. Name another site within the MNJ we could target to prevent muscle contraction, and explain why this would work.
An ion that is essential for muscle contraction is Ca2+. Which of the following statements about the calcium ion and muscle contractions is TRUE? Select one: a. Muscle contractions can occur whether Ca2+ concentrations are high or low. b. Ca2+ binds to the tropin-tropomyosin protein complex shifting it out of the way and allows the myosin to bind to the actin so contraction can occur. c. When Ca2+ concentrations are high, tropomyosin inhibits myosin binding and the muscle is relaxed. d. Ca2+ ions are stored in the sacroplasmic reticulum during the muscle contractions. I do not know which one is
