What are the 3 types of neuron?
Sensory, inter and motor
What are sensory neurons?
Sensory neurons are nerve cells that carry electrical impulses from sense organs to CNS.
What are motor neurons?
Motor neurons are nerve cells that carry electrical impulses from the CNS to muscles and glands (effectors)
What are inter neurons?
Inter neurons are nerve cells that are found in the CNS where they connect with other neurons
What do receptors do?
Receptors detect sensory input/stimuli
What do electrical impulses do?
Electrical impulses carry messages along neurons and chemicals transfer these messages between neurons, at synapses
What do reflexes do?
Reflexes protect the body from harm
What do the endocrine glands do?
The endocrine glands release hormones into the bloodstream
What are hormones?
Hormones are chemical messengers
What do target tissues have?
Target tissues have cells with complementary receptor proteins for specific hormones, so only that tissue will be affected by these hormones
What is insulin?

What is glucagon?
Glucagon is a hormone produced by the pancreas which triggers glycogen conversion into glucose
What is glycogen?
