Motor Neuron - ✔✔ANSWER✔✔-Carries info from central
nervous system to muscles and glands. Brain to Bod
Sensory Neurons - ✔✔ANSWER✔✔-Carry info from
sensory receptors to the CNS. Body to Brain
Interneurons - ✔✔ANSWER✔✔-Communicate within
CNS. Brain to Brain
Nervous System - ✔✔ANSWER✔✔-Electrochemical
communication network that consists of all of the nerve
cells of the peripheral and CNS. Communicates between
brain and body
,How do neurons communicate? - ✔✔ANSWER✔✔-Phase
1: electrical. Action potential. Within neuron.
Phase 2: chemical. Between different neurons. Chemicals
that are exchanged are neurotransmitters.

released by vesicles to be accepted by receptors; the
junction between the terminal branch of the sending
neuron and the dendrite of the receiving neuron
Multipolar neuron - ✔✔ANSWER✔✔-Multiple dendrites
One axon
Motor neurons and interneurons
Bipolar neuron - ✔✔ANSWER✔✔-One dendrite
One axon
Specialized sensory neurons
Pseudo-unipolar neuron - ✔✔ANSWER✔✔-One axon that
splits into two branches
Sensory neurons
Action potential - ✔✔ANSWER✔✔-The neural impulse
that travels down an axon
Agonists - ✔✔ANSWER✔✔-Bind to receptors and mimic
effects of neurotransmitter
,Antagonists - ✔✔ANSWER✔✔-Bind to receptors and
block subsequent functioning

most basic functions like heartbeat and breathing

making, speaking. Includes primary motor cortex
Temporal Lobe - ✔✔ANSWER✔✔-Auditory processing
Parietal Lobe - ✔✔ANSWER✔✔-Sensory input for touch
and position. Includes primary somatosensory cortex
Occipital Lobe - ✔✔ANSWER✔✔-Receives visual info
Cerebellum - ✔✔ANSWER✔✔-Balance and movement
