Document Summary

Endocrine system: endocrine system: responsible for the release of hormones into bloodstream. How do neurons communicate: neurons: cell of the nervous system that is specialized for sending and receiving neural messages, cell body: the large, central mass of a neuron, containing the nucleus. Components of the neuron: dendrite: receives input from other neurons, axon: transmits information to other neurons, myelin: insulating material covering some axons, glial cells: support cells found in the nervous system. Generating an action potential: synapse: point of communication between two neurons. Chemical signaling: neurotransmitters: a chemical messenger that communicates across a synapse, receptors: parts of the cell membrane that receive the neurotransmitter and initiate or prevent a new electric signal, neurotransmitters and receptors work like a lock and key. Releasing neurotransmitters: reuptake: molecules of neurotransmitter in the synaptic gap are returned to the axon terminal from which they were released.
