Neurotransmitters are chemicals released in minute amounts from the terminals of nerve cells in response to the arrival of an action potential. There are now more than 300 known neurotransmitters and they act either locally in point-to-point signal...

Chemical substances used for signalling between neurons in the nervous system. Transmitters are released at the SYNAPSE by the PRESYNAPTIC neuron into the SYNAPTIC CLEFT. They then bind to RECEPTORS on the POSTSYNAPTIC neuron or an effector organ such...

Neurotransmitters are chemical substances that transmit information between nerve cells, neurons, and between neurons and effectors, muscles or glands. The transmission occurs across a narrow gap or cleft at the synapse, microscopic distance between a...

Neurotransmitters are special chemicals which help to pass nerve impulses on from one neuron to another. When a nerve impulse runs down the axon of a neuron, ultimately it arrives at the axon terminal, where the synaptic knobs are located. The synaptic...

Neurotransmitters are chemicals that are used to relay, amplify and modulate signals between a neuron and another cell. According to the prevailing beliefs of the 1960s, a chemical can be classified as a neurotransmitter if it meets the following...

WHY YOU NEED ITA single ounce of dark chocolate is packed with literally dozens of nutrients and disease fighters, including FLAVONOIDS— powerful antioxidants that mop up the cell-damaging free radicals that have been linked to heart disease and cancer.

WHY YOU NEED EGGS The AMINO ACIDS in eggs are converted into muscle, skin, col- lagen, and other body tissue more efficiently than the proteins from any other food you can eat (or drink). — Egg yolks are packed with nutrients, including nearly half...

In a small study with big implications, researchers found some of the strongest evidence yet that sudden infant death syndrome _ a medical and sometimes legal mystery once known as crib death _ may be caused by brain stem abnormalities....

Using marijuana seems to increase the chance of becoming psychotic, researchers report in an analysis of past research that reignites the issue of whether pot is dangerous.The new review suggests that even infrequent use could raise the small but real risk of this serious mental...
