How many Neurons (nerve cells) are in the brain? 87 billion - making up half the brain cells. How many glial cells are in the brain? 86 billion - making up half the brain cells. Neurons (nerve cells) excitable cells that transmit electrical signals Glial cells cells in the nervous system that support, nourish, and protect neurons CNS (central nervous system) brain and spinal cord PNS (peripheral nervous system) the sensory and motor neurons that connect the CNS to the rest of the body ...

4 step of neurotransmitters 1. Chemical must be synthesized in the nueron 2. When neuron is active chemical must be released and produce a response in some target 3. A response must be obtained when a chemical is placed on its target 4. A chemical must exist for removing the chemical from its site of action How is ACh synthesized? Use of enzyme "Choline acetyltransferase" Acetly CoA + Choline > enzyme > ACh How is ACh made? Acetyl CoA carries acetate to the transmitter systems i...

Cerebrum Major structure of the forebrain that consists of two virtually identical hemispheres (left and right) and is responsible for most conscious behavior. Hemisphere "Half a Sphere", referring to one side of the cerebrum. Brainstem Central structure of the brain responsible for most unconscious behavior. Cerebellum Major structure of the branstem specialized for coordination and learning skilled movements. In large-brained animals, the cerebellum may also have a role in coordinat...
