Document Summary

One thing we have to do is sense and perceive the world around us, the environment. Secondly, we must respond to that environment of ours, to act upon it, to have some effectiveness of that world. This describes afferent processes related to inbound process, coming inward. Efferent processes- process exiting, emitting or going outward. At this level, sensation is an afferent process taking info in. The real building block of the brain is the neuron. Neurons have an amazing range of variety in shape and size. The longest ones we have is the from the base of our spine to our toes. The three parts are the cell body also known as soma (its brain center), branch like things called dendrites that operate of afferent process, and axon. Info comes in by dendrites, interpretation by cell body, then the longer part called the axon is the efferent component that will send a response out of the cell.
