Nervous System

Neuron

100

What part of the neuron carries electrical impulses away from the cell body?

Axon

200

What is myelin and what does it do?

coating on nerves that speeds up the rate of transmission

300

Which part of the neuron receives messages?

Dendrites

400

List the parts of a neuron 

Dendrite, cell body (nucleus), axon, axon tips

500

What is the message carried by a neuron called?

Nerve impulse

Types of Neurons

100

What type of neuron picks up on a stimulus and converts it to a nerve impulse?

Sensory Neuron

200

What type of neurons are found in the brain and spinal cord?

interneuron

300

What type of neuron sends a message to a muscle or gland enabling it to respond?

Motor neuron

400

What type of neurons carry impulses from the CNS to the body?

Motor neurons

500

What happens during most reflexes?

Sensory neurons detect stimulus- send impulse to spinal cord

Interneurons pass impulses two different directions- impulse sent to motor neuron to enable quick response and impulse sent to brain making person aware of what happened

Central Nervous System

100

What is the control center of the CNS

Brain

200

What part of the CNS links the brain with the peripheral nervous system?

Spinal cord

300

What protects the spinal cord?

Vertebral column, connective tissue, fluid

400

What part of the brain connects to the spinal cord?

Brain stem

500

List the 3 main regions of the brain

Cerebum, Cerebellum, Brain Stem

Peripheral Nervous System

100

What is the PNS?

network of nerves that branch out from the central nervous system and connect it to the rest of the body

200

What are the two different groups of nerves in the PNS?

Somatic and Autonomic

300

Which group of nerves controls voluntary actions and which group controls involuntary actions?

Somatic- Voluntary actions

Autonomic- involuntary

400

How many pairs of nerves in the peripheral nervous System?

43

500

Which group of nerves in the Peripheral Nervous system would connect to skin, sensory organs, and skeletal muscles?

Somatic

Miscellaneous Nervous System

100

Which region of the brain carries out complex mental processes, controls movement, and interprets input from your senses?

Cerebrum

200

What does the brain stem do and what is an example?

Controls the body's involuntary actions- breathing, heartbeat, etc

300

What is the function of the cerebellum?

Coordinates muscle actions and helps you keep your balance

400

What is a bundle of nerve fibers called?

Nerve

500

Which structure is considered the "information highway"?  Why?

Spinal cord
