Nervous System

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

• interneurons

• motor

• sensory

• receptors

If I step on a nail, what type of neurons take the response from the CNS TO an effector?

• motor neurons

• interneurons

• sensory neurons

• not neurons, muscle tissue sends the response

Which parts of the body make up the CNS?

• brain and spinal cord

• brain and vertabrea

• just the spinal cord

• just the brain

Which type of neurons make up the CNS?

• motor neurons

• interneurons

• sensory neurons

• True

• False

The change in an environment is called a(an)

• stimulus

• neurotransmitter

• effector

• homeostasis

The quick response to a stimulus without the use of the brain is called a(an)

• stimulus

• effector

• receptor

• reflex

Which type of neuron receives messages from and sends messages back into the peripheral nervous system during a reflex?

• sensory neurons

• motor neurons

• interneurons

• post synaptic neurons

What are on sensory neurons that allow them to detect a stimulus?

• motor neurons

• neurotransmitters

• receptors

• effectors

A chemical messenger produced by neurons are called

• neurotransmitters

• hormones

• cholesterol

• stimuli
