Hi
I have completed all of my A&P homework except for the following question which I do not understand: “Describe the three plexuses of mixed nerves:”
Does anyone have a clue where to start with this question?Many thanks, Mark.
Nothing strange in this question. Very simple and clear.
You can use any plexuses you know: cervical, brachial, lumbar, sacral, and also you can use other plexuses
I agree, the question could be worded more clearly !
However, given the requirement of 'three' I'd say it referred to the major voluntary plexuses - the cervical, brachial, and lumbosacral (sometimes considered as two distinct bodies, the lumbral and sacral plexus).
As for 'describe' I would start with a definition of a mixed plexus, then list the main nerves comprising the three major mixed plexuses......
Why 3? It depends what nerve system and where you consider....
