Ch 7 Part 1 Nervous System

What is a nerve cell?

• axon

• neuron

• dendrite

• myelin

What part of the nervous system is responsible for slowing down breathing and pulse?

• Spinal Nerves

• Sympathetic

• Parasympathetic

• Spinal Nerves

The long, fiber like part of a neuron which the cell sends information to receiving neurons

• axon 
• dendrite
• axon terminal
• gene

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

E

• Synapse
• Cell Body
• Axon 
• Dendrite

The part of the PNS that controls involuntary actions

• autonomic nervous system

• somatic nervous system

• organic nervous system

• reflexive nervous system

The part of the nervous system that consists of nerves that branch out from the CNS (central nervous system) and connect to other body parts

• Sympathetic
• Parasympathetic
• Autonomic
• Peripheral

A chemical produced by neurons that carries messages to other neurons

• myelin sheath
• neurotransmitter
• axon
• axon terminal

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

This part of the neuron stores then releases neurotransmitters into the synapse.

• Axon 
• Dendrite
• Myelin Sheath
• Axon Terminal
