Compare and contrast the actions of the endocrine system and the
nervous system to control body function
o Both the nervous system and endocrine system release ligands (hormones or
neurotransmitters) to communicate with target cells
Nervous system is fast-acting and short-lived with localized effects
Endocrine system is slower-acting and has a widespread and long-lasting effect
Describe the general functions controlled by the endocrine system
o Maintains homeostasis of blood composition and volume by regulating concentration of
specific substances in the blood
o Controls reproductive activities
o Regulates development, growth, and metabolism
o Controls digestive processes
Distinguish between the two types of organization of hormone cells
Endocrine glandstypically composed of a connective tissue framework which houses
and supports epithelial tissue that produces and releases hormones from their secretory
cells
Comparison of the Nervous System and Endocrine System
Features
Nervous System
Endocrine System
Communication
Method
A nerve signal
causes
neurotransmitter
release from a
neuron into a
synaptic cleft
Secretes hormones
into blood;
hormones secreted
into blood are
distributed
throughout body
Target of
Stimulation
Other neurons,
muscle cells, and
gland cells
Any cell within the
body with a
receptor for the
hormone
Response Time
Rapid response
time; typically
milliseconds or
seconds
Relatively slow
reaction time;
seconds to minutes
to hours
Duration of
Response
Short-term;
milliseconds;
terminates with
removal of stimulus
Long-lasting;
minutes to days to
weeks; may
continue after
stimulus is removed
