Displaying results 1 to 10.

1. Acetylcholine
A chemical found in vertebrate neurons that carries information across the synaptic cleft, the space between two nerve cells.

2. Acetylcholinesterase
An enzyme that breaks down unused acetylcholine in the synaptic cleft (the space between neurons); this enzyme is necessary to restore the synaptic cleft so it is ready to transmit the next nerve impulse.

3. Adrenergic
Refers to neurons that use catecholamines ( adrenaline , dopamine and noradrenaline ) as neurotransmitters .

4. Ganglia
Clusters of neurons that receive and process signals; found in flatworms and earthworms.

5. Glia
Nerve tissue other than the signal-transmitting neuron s. It is composed of glial cell s which are found interspersed between the neurons and acts as insulation and support for them.

6. Glial cells
Nonconducting cells that serve as support cells in the nervous system and help to protect neurons .

7. Gray matter
The portions of the brain and spinal cord which are gray and composed of the main bodies of neuron s (called cyton s). This is in contrast to white matter , which is the portions that are white and composed of the axon s and dendrite s of neurons. In the spinal cord, the gray matter is bordered by the white matter and is shaped like a butterfly when seen in cross-section.

8. Interneurons
neurons that process signals from one or more sensory neurons and relay signals to motor neurons . Aka connector neurons.

9. Midbrain
A network of neurons that connects with the forebrain and relays sensory signals to other integrating centers.

10. Motor neurons
neurons that receive signals from interneurons and transfer the signals to effector cells that produce a response. Nerve cells connected to a muscle or gland. Sometimes also known as effector neurons .
