chapter 48,49&50.5 review

What are neurons and what is their primary function?

Neurons are specialized cells that receive and transmit information, with their structure closely related to their function.

What are the main components of a typical neuron?

A typical neuron includes a cell body, dendrites, an axon, an axon hillock, synaptic terminals, and synapses.

What is the resting potential of a neuron?

The resting potential is the membrane potential of a resting neuron, typically between -60 and -80 millivolts (mV), with the inside being negatively charged relative to the outside.

What are action potentials and how are they generated?

Action potentials are rapid shifts in membrane potential used for signaling, generated when depolarization reaches a specific threshold, leading to the opening of voltage-gated sodium channels.
