Cog Sci c127 Midterm 1 exam | Questions and Correct Solutions | Latest Update 2024/2025 | Graded A+ The nervous system is composed of what two main classes of cells? What are they? - Answer -Neurons and glial cells -- neurons = the basic signaling units that transmit information through the nervous system -- glial cells = non neural cells that provide structural support and electrical insulation to neurons. Glia are involved in metabolic functions, repair and protection of neurons, and...

LIFSCI 7B XL - Animation: Reading Phylogenies Copy Questions and Answers Rated A+ What is the role of the axon hillock in neural signaling? The axon hillock integrates incoming signals and determines whether to initiate an action potential. How does myelination affect the speed of action potential propagation along an axon? Myelination increases the speed of action potential conduction by enabling saltatory conduction, where the signal jumps between nodes of Ranvier. Why do vo...
