Document Summary
Bio 103 chapter 45 & 46. 5 week 4 electrical signals in animals & movement. Describe the basic electrical properties of excitable cells and the ways cells produce a membrane potential. Explain how an action potential is produced and propagated along a neuron. Discuss the different types of synapses that mediate communication between two neurons or between a neuron and another cell type. Discuss the basic features of the vertebrate nervous system, distinguishing between the central and peripheral nervous systems. Discuss the features of muscle cells and how they are activated to cause contraction. Neurons conduct info in form of electrical signal. Neurons conduct them from point to point in the body at speeds of up to 200m/s. Cephalization phenomena about evolution of bilaterally symmetric body with information gathering and processing structures located at the head end. Made animals into efficient eating & moving machines.
