Glossary

Afferent Messages: 

carry sensations such as heat, cold, or pain

Autonomic System: 

deals with the visceral organs, like the heart, stomach, gland, and the intestines

Axon: 

the part of the neuron that conducts nerve impulses

Cannabis: 

a psychoactive drug produced from parts of the cannabis plant

Central Nervous System (CNS): 

the system that includes the brain and the spinal cord

Cerebellum: 

part of the brain that is located posterior to the medulla oblongata and pons, coordinates skeletal

muscles to produce smooth, graceful motions

Cerebrospinal Fluid (CSF): 

acts a shock absorber for the central nervous system, protecting the brain and spinal

cord from injury; it also has a high glucose content which serves as a nutritional factor

Cerebrum 

motor control, learning, speech, somatic sensory functions, vision,hearing and more.

Dendrites: 

short pieces that come off of the cell body that receive the signals from sensory receptors and other

neurons

Episodic Memory: 

represents our memory of events and experiences in a serial form

Excitatory Neurotransmitter: 

a neurotransmitter that acts to elicit an action potential by opening chloride ion

channels

Longitudinal Sulcus: 

separates the cerebrum in to the right and left hemispheres

Long Term Memory: 

used for storage of information over a long time

Long-Term Potentiation (LTP) 

long term communication enhancement between two neurons. Results in neural

pathways that store memoris.

Medulla 

control center for respiratory, cardiovascular and digestive functions.
