HBS Unit 5

which is the correct path that a nerve impulse will follow in a reflex arc?

• motor neuron--> interneuron--> sensory neuron

• interneuron--> motor neuron --> sensory neuron

• motor neuron--> sensory neuron--> interneuron

• sensory neuron--> interneuron--> motor neuron

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 does the neuron's Myelin Sheath 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

• Surrounds and insulates the axon

What do Dendrites 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

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

What do Axon Terminals 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

Depolarization is occuring at number

• 1

• 2

• 4

• 5

What number(s) on the graph represents the Resting Potential?

• 1 and 2

• 1 and 5

• 2 and 3

• 3 and 4
