|
|
What general area of the body is not extensively supplied with free nerve endings
|
Most deep tissues of the body are not extensively supplied with free nerve endings
|
|
|
Free nerve endings that are responsible for "sharp" or "electric" pain have what type of neuron associated with them? How fast or slow is the pain felt? what is an example of a neurotransmitter associated with this type of pain?
|
has a neuron type of Aδ
pain is usually felt within 0.1 seconds Example of a NT is glutimate, which exists for only milliseconds |

Free nerve endings associated with "aching" "throbbing" or "burning" pain usually indicates what type of tissue damage? What type of neuron does this typeof nerve ending use? What is an example of a neurotransmitter associated with this type of pain?
|
Indicates tissue destruction
uses a C neuron An example of a neurotransmitter associated with this type of pain is substance P, which exists for seconds to minutes |
