nervous system
the spinal cord's purpose
an information highway, connecting the peripheral nervous system to the brain
a neuron is...
nerve cells that send messages all over your body
hemispheres of the brain
2; right and left
difference between the endocrine system and the nervous system
the endocrine is known as the slow communication system and the nervous system is much faster.
how does the information from the peripheral nervous system travel
nerves
3 main parts of the neuron
cell body (soma)
axons
dendrites
responsibilities of the cerebral cortex
outer layer of the brain, responsible for reasoning and thinking
messengers of the endocrine system
hormones
the two branches of the autonomic nervous system and their primary functions
sympathetic (fight or flight)
parasympathetic (rest and digest)
the part of the neuron that receives signals
dendrite
responsible for balance and is located on the very back of the head; the "little brain"
role of the hypothalamus in the endocrine system
acts as a control center and regulates the release of hormones
difference between central and peripheral nervous system
the CNS processes information and sends signals, while the PNS transmits those signals to different parts of the body.
importance of neurotransmitters
they carry chemical signals from one neuron to the next target cell
difference in brocas area and Wernickes area
brocas is responsible for producing speech
wernickes is responsible for comprehending speech
the pituitary gland is...
the master gland, as it controls all functions of the other glands
side affects of sympathetic nervous system
when the body is enraged, alarmed, or challenged, the SNS will accelerate the heartbeat, raise the blood pressure, slow digestion, raise blood sugar, making the body alert and ready for action.
the two neurotransmitters closely related to schizophrenia
dopamine and glutamate
the 5 different areas of the brain and their function
frontal lobe
parietal lobe (sensory)
temporal lobe (hearing)
cerebellum (balance)
occipital lobe (vision)
the 5 hormones learned in this chapter
1. acetylcholine (muscle, instincts)
2. norepinephrine/epinephrine (adrenaline)
3. dopamine (motor control/planning)
4. serotonin (sleep cycle, mood, memory, learning)
5. endorphins (regulate pain)
