Biology of the Brain

1. the brain and the spinal cord
4. cell body that maintains the health of the neuron
5. the neurons that carry incoming information from the sense receptors to the central nervous system
6. everything other than the brain and spinal cord
8. controls the glands and the muscles of the internal organs
9. support that access cells by providing nutrition structural support
11. heightened levels of fearfulness, anxiousness
12. electrical signals travelling down the axon
13. when neurotransmitters are not picked up by a receiving neuron so they are reabsorbed by a sending neuron
15. protects the axon and speeds up the neural impulse
16. the endpoint of neurons

2. the body’s speedy electrochemical system
3. extensions of neurons that receive info
4. controls all of the body’s skeletal muscles
5. The minimum level of stimulation needed to activate the next neuron
7. central nervous system neurons that internally communicate and intervene between the sensory inputs and motor outputs
10. simple automatic responses to sensory stimuli
14. nerve cell, building block of the nervous system
16. the extension of a neuron through which neural impulses
