Several hormones, as well as the neurotransmitters, are produced by the tissues in the Central Nervous System.Some neurotransmitters and hormones have a similar.They release form vessels into the surrounding fluid by similar mechanisms.Both neurotransmitters and hormones are chemical messengers.What are the Similarities Between Neurotransmitters and Hormones? Hormones affect many different processes in our body including, growth, sexual function, reproduction, mood, metabolisms, etc. Hormones are able to stimulate a specific set of cells that locate somewhere else and have no direct connection with their glands. Glands are the organs that produce and secrete hormones while target organs are the organs they affect. Endocrine system secretes hormones into the blood, and via the circulatory system, they reach the distant target cells. Hormones are the chemical messengers produced by the endocrine system. Some common examples of neurotransmitters are acetylcholine, dopamine, glutamate, glycine, serotonin, histamine and noradrenaline. This action of neurotransmitters can be three ways excitatory, inhibitory or modulatory. The binding of neurotransmitters with receptor proteins will stimulate postsynaptic neuron and continue the nerve transmission. They diffuse through the cleft and reach the postsynaptic membrane and bind with the receptors located on the membrane surface.
Therefore, the presynaptic neuron membrane creates vesicles filled with neurotransmitters and release into the synaptic cleft. Hence, neurons use neurotransmitters to pass the action potential from the presynaptic membrane to the postsynaptic membrane (from the axon of one neuron to the dendrites of the second neuron). Synaptic cleft is the region where two neurons come closer but do not touch with each other. Neurotransmitters facilitate the transmission of a nerve impulse or action potential across the synaptic cleft. They can be small amine molecules, amino acids, or neuropeptides. Neurotransmitters are chemical messengers of our nervous system. Side by Side Comparison – Neurotransmitters vs Hormones in Tabular Form Similarities Between Neurotransmitters and Hormonesĥ. These neurotransmitters and hormones act as chemical messengers and facilitate the nerve impulse transmission and the regulation of physiological activities in our body.
Both systems are dependent on the release of special chemicals either as neurotransmitters or as hormones respectively. Nervous system and endocrine system are very important organ systems in our body that regulate various activities. The key difference between neurotransmitters and hormones is that neurotransmitters are the chemical messengers used by the nervous system to transmit nerve impulse across the synapses while hormones are the chemical messengers used by the endocrine system to stimulate or communicate with specific targets cells.
