LIST 5 parts of the neuron below (you don’t have to label the parts—just use the picture as a guide), AND describe the function of each part (1 point for each correct label, 1 points for each correct function). 1) Dendrite: Dendrites are at the beginning of a neuron (treelike extensions), covered with synapses and dendrites help increase the surface area of the cell body. Dendrites receive information from other neurons and transmit electrical stimulation to the soma. 2) Soma (cell body): The factory of the neuron. It produces all the protein for the axons, dendrites and synaptic terminals. It decides whether the neuron will fire or not. 3) Axon: The axon is the elongated fiber that extends from the cell body to the terminal endings and carries the signal to the terminal branches. 4) Myelin Sheath: Myelin Sheaths function is to increase in the speed at which impulses propagate along the myelinated' fiber. 5) Nucleus: The nucleus regulates all cell activity. It is the brain or control center of the neuron.
