A neural __________ or, chemical messenger, travels across the synapse and binds to a neural __________.
Identify the main components of the nervous system and explain its three main functions.
The nervous system is comprised of neurons or nerve cells. The nervous system collects information about the bodies internal and external states, analyzes the collected info once it has reached the brain and sends impulses out to initiate appropriate responses. Responses may vary but should include some or all of the following information: The nervous system is comprised of neurons, or nerve cells. The nervous system collects information about the body’s internal and external states, analyzes the collected information once it has reached the brain, and sends impulses out to initiate appropriate responses.
Explain how glia function within the nervous system.
Glia are support cells that nourish, protect, and insulate neurons. They maintain the chemical environment around neurons, remove waste, help repair nervous tissue, and assist neural communication. Glia can also influence processes such as memory, pain perception, and psychological disorders.
According to new research, glia may be able to send and receive messages like neurons. They may also influence memory formation, play a role in how we perceive chronic pain, and perhaps even contribute to psychological disorders when communication breaks down between the glia and neurons. Knowing this, all of the following could be linked to glia except __________. According to new research, glia may be able to send and receive messages like neurons.

Explain the process of synaptic transmission, beginning with the neurotransmitters at the axon terminal of the presynaptic cell and ending with the impulse being sent down the postsynaptic cell.
Synaptic transmission occurs when neurotransmitters reach the axon terminals of the presynaptic cell. They are then released into the synapse and travel across to the postsynaptic cell. On the postsynaptic cell they bind to neural receptors on the surface of the cell. This initiates communication between the two neurons and a neural impulse is sent down the postsynaptic cell. Any neurotransmitters left in the synapse are reabsorbed into the presynaptic cell through the reuptake mechanism.
