- a An efferent branch of the vertebrate peripheral nervous system that regulates the internal environment; consists of the sympathetic, parasympathetic, and enteric divisions.
- b One of the tree divisions of the autonomic nervous system; generally increases energy expenditure and prepares the body for action (Fight or Flight) - causes increase in heart rate, breathing, slows digestion, liver releases glucose, inhibits emptying of bladder, releases adrenaline from adrenal medulla situations:(emergency, embarrassment, exercise, excitement)
- c An organism that is warmed by heat generated by their own metabolism, Heat usually maintains a relatively stable body temperature higher than that of the external environment.
- d A substance that an organism cannot synthesize from any other material and therefore must absorb in preassembled.
- e ...

- Sheets of tightly packed cells that line organs and body cavities as well as external surfaces
- In a neuron, a shift in the membrane potential that has an amplitude proportional to signal strength and that decays as it spreads.
- The short time immediately after an action potential in which the neuron cannot respond to another stimulus, owing to the inactivation of voltage-gated sodium channels
- The sensory and motor neurons that connect to the central nervous system
5 True/False questions
Myelinated Sheath → The total amount of energy an animal uses in a unit of time.
Muscle Tissue → Tissue consisting of long muscle cells that can contract, either on its own or when stimulated by nerve impulses
Spatial Summation → A phenomenon of neural integration in which the membrane potential of the post-synaptic cell is determined by the combined effect of EPSPs or IPSPs produced nearly simultaneously by different synapses.
Depolarization → A change in a cell's membrane potential such that the inside of the membrane is made less negative relative to the outside. For example, a neuron membrane is depolarized if a stimulus decreases its voltage from the resting potential of -70 mV in the direction of zero voltage.
Neurotransmitter (NT) → ...
