Nervous System and Neurons

Type of neuron that perceive information about your environment.

• Motor Neuron

• Interneuron

• Sensory Neuron

Neurons that carry information from the sensory receptors to the CNS:

• Sensory, afferent

• Sensory, efferent

• Moror, afferent

• Motor, efferent

A soccer ball comes flying toward you. You throw up your hands to be avoid being hit in the face. Which is the stimuli?

What are the two divisions of the autonomic nervous system?

• central and peripheral

• parasympathetic and sympathetic

• brain and spinal cord

• nerves and ganglia

The tiny gap between neurons where nerve impulses are sent from one neuron to another.  It is where communication occurs between an axon and dendrite

• synapse
• axon terminal
• impulse
• myelin

The "fight or flight" response during threatening situations in the role of the:

• sympathetic nervous system
• parasympathetic system
• somatic nervous system
• cerebellum

This insulating material forms a layer, around the axon of a neuron.  It enables electrical signals to travel down the axon at higher speeds.

• neuron
• myelin sheath
• dendrite
• neurotransmitter

The nervous system_________

• receives information about what is going on in your body as well as what is going on around you. 
• tells your body how to react to the information it receives. 
• helps your body maintain homeostasis. 
• all of the above.

A nerve cell that is the basic working unit of the brain and nervous system which processes and transmits information

• axon
• neuron
• dendrite
• neurotransmitter

• Nucleus

• Cell Body

• Axon

• Node of Ranvier
