Proprioceptors, Cutaneous Receptors, & Pain Receptors

Introduction: Here are some more specific receptors that can be found in the body. They include identifying where one is positioned, all of the different feelings that come from the skin, and pain.

Proprioceptors:

Here is a picture from http://www.pilotfriend.com.


*Proprioceptors

~Mechanoreceptors that gives body position

~Allows one to touch their nose with eyes shut


Cutaneous Receptors:

Yes, this is a picture of the skin, but that is because cutaneous receptors are in the skin. This picture was found at http://upload.wikimedia.org.

*Cutaneous

~Receptors of the skin

~Dermis layer of the skin contains the cutaneous receptors, making the skin

sensitive to touch, pressure, pain, and temperature


Pain Receptors:

Last but not least are the pain receptors (located in the skin). This picture is from http://www.instruct1.cit.cornell.edu.

*Pain Receptors

~Also called nociceptors

~Sensitive to chemicals released by damaged tissue

~Referred pain: stimulation of internal pain receptors is felt as skin pain as well as

internal organs


Conclusion: That concludes a deeper look at some of the receptors in our body. Next up, for the next few, we will be taking a look at the different senses we experience. These are sometimes known as "the five senses." We will not be discussion touch though.

Hi Katie, I'm looking for better info about thermalreceptors on skin. I dedicate my studies in thermal comfort, and would like some bibliografic references about. Other question, is biosensory relate with this subject? my email is jeangoedert@gmail.com
thank you, regards, Jean.

Hi my name is Emma, and I am doing a human biology assignment and there seems to be little information about types of receptors such as propioceptors, photoreceptors, chemoreceptor and thermoreceptors. I was wondering if you were able to help. my email is 10omaem@stmarys.wa.edu.au
