2.86: Describe How Nervous and Hormonal Communication Control Responses and Understand the Differences Between the Two Systems

NERVOUS COMMUNICATION: Nervous system comprising a network of nerve cells that carry impulses between parts of body

HORMONAL COMMUNICATION: Endocrine system comprising glands that produce and secrete Hormones to stimulate change in the body

NERVOUS COMMUNICATION	HORMONAL COMMUNICATION
Diagram showing the Nervous System	Diagram showing the Endocrine System
Stimulation of receptors in sensory organs sends electrical impulses around the body Messages are carried by electrical impulses along nerves and neurons Electrical impulses are fast but short-lived	Endocrine glands produce specific Hormones that causes change to the body Hormones are transported to target organs via bloodstream Chemical signals are slow but long-lived
SIMILARITIES: Requires Stimuli, Receptor and Effector
DIFFERENCES: Nervous communication is electrical, while Hormonal communication is chemical Nervous Communication is faster, while Hormonal communication is slower Nervous communication is short - lived, while Hormonal communication is long - lived
