Neurotransmitters to the synapse and the neurotransmitters bind with the receptors releasing the second messengers.
Neurotransmitters are released into the synapse by the presynaptic neuron.
The opposite of dopamine in terms of neurotransmitters is serotonin.
Neurotransmitters are secreted from the axon terminals of neurons in the brain and nervous system.
Astrocytes and microglia are two types of glial cells that help remove neurotransmitters from receptor sites in the brain. They play a crucial role in maintaining the balance of neurotransmitters in the synapse by clearing excess neurotransmitters and preventing overstimulation of the neurons.
neurotransmitters
The neurotransmitters from one neuron have direct effect on the next neuron. They are channels that are used to transmit messages in the nerves.
Direct acting cholinergic drugs directly bind to and activate cholinergic receptors, while indirect acting cholinergic drugs increase cholinergic activity by inhibiting the enzyme acetylcholinesterase, which breaks down acetylcholine. Direct acting drugs include bethanechol and pilocarpine, while indirect acting drugs include donepezil and physostigmine.
A Direct Acting (DA) pneumatic thermostat increases branch line pressure as temperature increases. A Reverse Acting (RA) pneumatic thermostat decreases branch line pressure as temperature increases.
Imitrex (sumatriptan) is not an opiate medication. It relieves pain by acting on neurotransmitters in the brain to reduce inflammation and constrict dilated blood vessels.
When actuator travels in the direction of air supplied, then the actuator is called direct acting actuator.
When a pressure signal is applied, the valve shaft moves in the direction opposite that of the direct-acting actuator, but it follows the same operating principle. In the reverse-acting actuator, the valve shaft is pulled into the actuator by the application of a pressure control signal.
Neurotransmitters act on synapses.

A direct acting solenoid valve is one in which the action of the solenoid alone switches the valve gate. Most solenoid valves are "piloted", which means that a relatively small solenoid valve is used to allow pressurized air to actuate the valve gate mechanism. Because the solenoid does all of the work in a direct acting valve, the solenoid must therefore be larger than that of a piloted valve in order to generate the switching force. Piloted solenoid valves have the advantage of being more compact and consuming less current than a direct acting solenoid valve. Direct acting solenoid valves are useful when switching low pressure fluids.
