Q

The PNS serves two main functions

A
  1. Provide connection for the nervous system to activate effector (organ, muscle) sites. 2. Relay information from effort site back to the brain via sensory receptors

Q

Mechanoreceptors

A
  • Sense mechanical information or body distortions such as: touch, pressure, stetching and motion
  • Sends info to CNS
  • CNS processes
  • CNS sends info back to muscles to act
