What is a neurotransmitter?
Neurotransmitters are chemical messengers that cross the synaptic gaps between neurons. Neurotransmitters travel across the synapse and bind to receptor sites on the receiving neuron when released by the sending neuron.
How do neurons transmit messages?
Neurons transmit messages through fibers that branch from them. These fibers receive and integrate information, conducting it toward the body. Then, a cell's single fiber actually transmits the message via its terminal branches. This single, lengthy fiber is called the AXON and is responsible for transmitting messages between neurons.
Why is the hypothalamus so important?
Because it regulates the pituitary gland. This gland regulates the endocrine system which regulates our hormones.
What does an agonist and antagonist do?
Agonist: A molecule that increases a neurotransmitter's action.
Antagonist: A molecule that blocks or restrains a neurotransmitter's action.
