2.83: Describe How Responses can be Controlled by Nervous or Hormonal Communication and Understand the Differences Between the Two Systems

NERVOUS COMMUNICATION: Nervous System that is Comprised of a Network of Nerve Cells that Carry Impulses Between Parts of the Body

HORMONAL COMMUNICATION: Endocrine System where Glands Produce Hormones that Stimulates Change in the Body

NERVOUS COMMUNICATION
HORMONAL COMMUNICATION
Diagram Showing the Nervous System
Diagram Showing the Endocrine System
  • Stimulation of Receptors in Sense Organs Sends Electrical Impulses
  • Messages are Carried by Electrical Impulses Along Nerves and Neurons
  • Fast Impulses
  • Short - Lived

  • Endocrine Glands Produce Hormones
  • Hormones are Carried by the Plasma to Target Organs to Stimulate Change
  • Slow as it is Carried by Plasma
  • Long - Lived
SIMILARITIES:

  • Chemicals Involved
  • Requires Stimuli, Receptor and Effector

DIFFERENCES:

  • Nervous Communication is Faster, Hormonal Communication is Slower
  • Nervous Communication is Electrical, Hormonal Communication is Chemical
  • Nervous Communication is Short - Lived, Hormonal Communication is Long - Lived
