Is the nervous system electrical or chemical
Witrynathat are alike in the brain, meaning that the heart has its nervous system. Neurons use electrical and chemical signals to send information between different areas of the brain, the spinal cord, and the entire body. 10 Apr 2024 10:18:57 WitrynaIn the nervous system, a synapse [1] is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or to the target effector cell. Synapses are essential to the transmission of nervous impulses from one neuron to …
