anatomy question - muscle function

Members don't see this ad.

Discussing the muscles an their functions we were told that there is a muscle (group?) which primary contributes to monitor the movements of the body. Unfortunately my attention was attracted by something different 😀 so I only kept the term "kinesiological monitors". (I'm NOT talking about the muscle spindles!)


As far as I remember it was one of the back muscles... (or not?)

any ideas?

How does a muscle moniter the movement of the body? Can you explain what you mean? I found this website ( http://www.biology-online.org/9/11_control_body_movement.htm ) that talks about control of body movement, maybe it will help? Or this : http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=6235379&dopt=Abstract .

golgi tendon organs, u mean? that's something else similar to muscle spindles.

Could they have been talking about propioceptors?

Though not really a part of monitoring, I think you are talking about gamma motor neurons and their effect on spindle length. By shortening spindle length, gamma motor neurons do have some effect on contraction. Ie, if you stimulate a gamma motor neuron without a concominant stimulation of alpha motor neurons, you can cause a reflexive contraction. This does happen to an extent when you are readying yourself for an impact, though it is more to increase the sensitivity of the reflexes.

As far as monitoring goes, you have GTO's for tension; for intrafusal (spindles), you have dynamic nuclear bags (velocity), static nuclear bags and nuclear chains (both static measurements). These signals, along with others, give a sense of proprioception.

Hope this helps.

yeah, but he said muscles specifically, you're talking about neuro stuff.

he said kinesiological monitors, actually, not muscles. Also, muscle function is intimately related to neurology.

Actually he said: "Discussing the muscles an their functions we were told that there is a muscle (group?) which primary contributes to monitor the movements of the body." Oh, and thanks for reminding me that muscle function is intimately related to neurology. I didn't know that.

I'm gonna assume that the last two sentences there are sarcasm.

if u knew that, then quit being sarcastic and quit telling people to stop talking about neurology because everything he's talking about points directly towards neurological mechanisms for assessing body position and movement.

I realize that he was asking about a specific 'muscle group'. To my knowledge, there are no specific muscles that take measurements, but muscles have intrinsic components that monitor movements. This was prob what his prof was talkign about.

Thanks Rendar.
