Biopsychology: The Structure Of A Neuron

Question 1

What Is The Sensory Neuron?

Answer 1

• Role: Carry nerve impulses sensory receptors to the spinal cord and brain (from the PNS to the CNS).
• Location: Receptors are located on or near the body’s surface.
• Length Of Axon: Short.
• Length Of Dendrite: Long.

Question 2

What Is The Relay Neuron?

Answer 2

• Role: Allows sensory and motor neurons to communicate with each other. They are the most common type of the neuron in the CNS.
• Location: Brain, Spinal Cord, Visual System.
• Length Of Axon: Short.
• Length Of Dendrite: Short.

Question 3

What Is The Motor Neuron?

Answer 3

• Role: Carry nerve impulses from the spinal cord and brain to the effectors (muscles and glands) from the CNS to the PNS.
• Location: Axons directly or indirectly linked to muscles.
• Length Of Axon: Long.
• Length Of Dendrite: Short.
