1. ___ dermatomes
2. ___ myotomes
3. ___ referred pain

a. muscle groups connected to spinal nerve roots
b. skin areas connected to spinal nerve roots
c. pain felt in a different area than the injury site

Explanation:

The questions require matching anatomical and physiological terms related to the nervous system with their correct definitions.

• Sensory impulses carry information from receptors in the body toward the central nervous system (brain).
• Motor impulses carry signals from the brain to the body to initiate action.
• Meninges are the three layers of protective membranes (dura mater, arachnoid mater, and pia mater) surrounding the brain and spinal cord.
• The Peripheral nervous system consists of all nerves located outside the central nervous system.
• Sensory nerves are responsible for gathering input from the skin, muscles, and joints.
• Motor nerves transmit signals to muscles to control movement.
• Dermatomes refer to specific areas of skin supplied by a single spinal nerve root.
• Myotomes refer to groups of muscles innervated by a single spinal nerve root.
• Referred pain is a phenomenon where pain is perceived at a location other than the site of the painful stimulus/injury.
