System.
AP Biology Curriculum objectives
Essential Knowledge: Animals have nervous systems that detect external and internal signals, transmit and
integrate information and produce responses.
A. The neuron is the basic structure of the nervous system that reflects function.
1. A typical neuron has a cell body, axon and dendrites. Many axons have a myelin sheath that acts as
an electrical insulator.
2. The structure of the neuron allows for the detection, generation, transmission and integration of
signal information.
3. Schwann cells, which form the myelin sheath, are separated by gaps of unsheathed axon (nodes of
Ranvier) over which the impulse travels as the signal propagates along the neuron.
B. Action potentials propagate impulses along neurons.
1. Membranes of neurons are polarized by the establishment of electrical potentials across the
membranes.
2. In response to a stimulus, Na+ and K+ gated channels sequentially open and cause the membrane
to become locally depolarized.
3. Na+/K+ pumps, powered by ATP, work to maintain membrane potential.
C. Transmission of information between neurons occurs across synapses.
1. In most animals, transmission across synapses involves chemical messengers called
neurotransmitters.
 Illustrative examples (choose at least 2)
 Acetylcholine
 Epinephrine
 Norepinephrine
 Dopamine
 Serotonin
 GABA
2. Transmission of information along neurons and synapses results in a response.
3. The response can be stimulatory or inhibitory.
D. Different regions of the vertebrate brain have different functions. (In Chapter 49/50)
 Illustrative examples (choose at least 2)
o Vision
o Hearing
o Muscle movement
o Abstract thought and emotions
o Neuro-hormone production
o Forebrain (cerebrum), midbrain (brainstem) and hindbrain (cerebellum)
o Right and left cerebral hemispheres in humans
Note: You DO NOT need to know the types of nervous systems, details of various structures and features of
the brain parts, and details of specific neurologic processes.
