Specialized Nerve Cells Notes – Nervous System 2 Specialized Nerve Cells

1. Brain •Processes the electrical signals sent from each receptor and decides on how to respond to the stimuli

2 Touch Receptors Convert mechanical stimuli in the form of pain, temperature, and pressure into electrical impulses. They are found in your skin.

3 Hair Receptors Convert mechanical sound wave stimuli that travel through the air into electrical impulses. They are found in your ears.

4 Rods and Cones Receptors Convert electromagnetic waves (light) stimuli into electrical impulses. These are found in your eyes.

5 Taste Receptors Convert chemical stimuli in the food you eat into electrical impulses. They are found on your tongue.

6 Olfactory Receptors Convert chemical stimuli (molecules) in the air into electrical impulses. They are found in your nose.

7 Neurons Cells Nerve cells that carry information as tiny electrical signals between the receptors and the brain

8 Spinal cord Pathway for neural fibers traveling to and from brain; controls simple reflexes that are not sent to the brain.

9 Nerve Carry electrical signals like a wire to and from the brain. (side roads)
