HBS Unit 4

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

• axon

• neuron

• dendrite

• neurotransmitter

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

A chemical produced by neurons that carries messages to other neurons

• myelin sheath

• neurotransmitter

• axon

• axon terminal

W

• Axon Terminal Button

• Neurotransmitters

• Dendrite

• Synapse

Y

• Axon Terminal Button

• Neurotransmitters

• Dendrite

• Synapse

Z

• Axon Terminal Button

• Neurotransmitters

• Dendrite

If I step on a nail...what type of neuron take that signal TO the CENTRAL NERVOUS SYSTEM?

• interneurons

• motor

• sensory

• receptors

If I step on a nail...what type of neurons send the response from the brain to my muscles?

• motor

• interneurons

• sensory

• not neurons, muscle tissue sends the response

What does the neuron's nucleus do?

• Controls the actions of the neuron

• Produces food for the neuron

• Carries information from the cell body to other neuronsThis is a wrong answer

• Controls speed of electrical signal through the axon

What do Schwann Cells do?

• Intakes information from other neurons

• Produces fatty tissue for the Myelin Sheath

• Sends information to the next cell

• Controls the speed of electrical signal through the axon
