Site Plan | I. Neurons/nerve cells A neuron is a cell specialized to conduct electrochemical impulses called nerve impulses or action potentials. Neuron is the main cellular component of the nervous system‚ a specialized type of cell that integrates electrochemical activity of the other neurons that are connected to it and that propagates that integrated activity to other neurons. They are the basic information processing structures in the CNS.

Individual Exercise 3 (10 points) 1. A shoe manufacturer’s data show that the distribution of shoe size is normal with a mean of 11inches and SD 1.5 inches. * A manger of the company claims that 70% of the times shoe size will be between 8 and 12 inches. What do you think? In your deliverables‚ write a few lines about what you think of the manager’s claim and what would you advise him to do.

REVIEW SHEET EXERCISE 2 Skeletal Muscle Physiology NAME: Jasmine Young LAB TIME/DATE: 1. Define each of the following terms: • motor unit - A motor unit consists of a motor neuron and all of the muscle fibers it innervates. • twitch - Skeletal Muscle twitch is the mechanical response to a single action potential. It has three phases known as the latent‚ contraction‚ and relaxation phase. • threshold - the threshold is the minimal stimulus needed to cause a depolarization of the muscle plasma membrane
