What fatty tissue speeds up neural impulses?

• Corpus Callosum

• Myelin Sheath

• Multiple Sclerosis

• Synapses

What are the two main parts of the nervous system?

• Frontal Nervous System and Partial Nervous System

• Sympathetic and Parasympathetic

• Central Nervous System and Peripheral Nervous System

• Occipital and Temporal Lobes

What is the level of stimulation required to trigger a neural impulse called?

• Dendrite

• Glia

• Action Potential

• Threshold

Define the All-or-None Response

• The body will receive sensory input at all times and be constantly firing

• Nerve cells either fire at full strength or not at all

• All reflexes will bypass the brain and exist only in the spinal cord

• The brain is able to heal certain injuries, so long as they happen early enough in development

What is a synapse?

• Point of connection between neurons

• Gap in the myelin sheath

• Message sent through an axon

• Simple, automatic response to sensory stimulus

What is reuptake?

• Part of the message is reabsorbed and does not all send

• All of a message sends

• A reaction to pain

What part of the nervous system consists of the brain and spinal cord?

• Central Nervous System (CNS)

• Autonomic Nervous System (ANS)

• Peripheral Nervous System (PNS)

• Somatic Nervous System (SNS)
