The nerve cell has four main parts to it: the cell body, dendrites, axon and axon terminals. The axon is covered in a lipid and protein based insulator called the myelin sheath. This makes the signals that are sent down the axon go faster and are more efficient. The purpose of the neurons is to send signals from the brain and central nervous system to the peripheral nervous system. The signals are sent from the dendrites, through the cell body and down the axon. It then goes to the axon terminals where it is transferred to the dendrites of the next neuron. The Sodium-Potassium pump assists in sending these signals down the axon. At the end, between the axon terminal of one neuron and the dendrite of the next there is a gap in between called the synaptic cleft. This is where signals and neurotransmitters are transferred through the body.
I really like the diagram you included, it's helpful to have a visual of your description.
ReplyDeleteI like that you explained the journey that the signal travels through the cell
ReplyDeleteI like how you were able to concisely describe the process that a neuron goes through in transmitting signals throughout the nervous system.
ReplyDeleteI really liked how you described the whole process of how neurons transfer signals. It made it easy to understand!
ReplyDeleteHey Hailey, I like the directive wording of your paragraph and the helpful use of definitions in your post. It lets the reader follow along and pick up on the anatomical jargon in your post.
ReplyDeleteI really liked that you added a picture to show all the different pieces of the nerve cell you talk about. It really adds to your description of what all the pieces do.
