When a nerve impulse (or action potential) triggers the release of neurotransmitters, these chemicals are then released into the synapse and then is taken up by the receptors on the next neuron. Hyperthyroidism (overactive thyroid). In order for neurons to send messages via neurotransmitters, they need to communicate with each other, which they do through synapses. Adrenaline is released mainly through the activation of nerves connected to the adrenal glands, which trigger the secretion of adrenaline and thus increase the levels of adrenaline in the blood. Adenosine is a neuromodulator type of neurotransmitter which functions in suppressing arousal and improving sleep cycles. Sensory nerve impulses reaching the brain regulate the release of the hormone from the nerve endings into the blood within the corpora cardiaca. When this happens, it can have a number of effects on your health. Research has shown that regular exercise improves dopamine signaling in people with early stage Parkinsons disease. The end of each neuron has presynaptic endings and vesicles, which are sacks containing neurotransmitters.
