i needed to know who i'm talking to, and i wasn't wrong:
after reaching 120 angle degree in the humerus, the rest of the movement is done by the trapezius using 'force couple' with upper+lower traps and serratus anterior. upper trapezius receive assistance from levator scapula and rhomboids whilst raising the scapula (at this point middle deltoid starts working isometrically), so there are two 'agonists' in two different muscle groups, using two different (combined) motions.
the real synergist here is the supraspinatus. completely forgot about that one.
the stabilizers are just the long head * brachii, not the entire tri's & bi's. you forgot the tri's actual extension which is agonistic to the forearm.
you forgot the actual term which is scapulohumeral rhythm.
"scapulae" isn't a stabilizer, it's a bone structure. you probably mean the levator (i hope).
what about insertions & origins?
oh nvm,
thanks for playing.
First of all, I do not appreciate your condescending tone - nor do I appreciate your vague attempts to "test" my knowledge by asking these questions.
To clarify, when saying "Scapulae" it refers to the Levator Scapulae. Although that would be too difficult for you to understand in simplified terms I'm assuming?
Secondly, why are you attempting to give an anatomy lesson here? I could write paragraphs about the biomechanical muscle configuration and response to the military press - but then again you are not my Anat/physio teacher.
You came to me asking a series of specific questions. I began to answer them (in a rather simplified form for ease of response) before I realized that you probably were writing a paper and could use some resources. Rather than just continue the journey of writing the paper for you, I figured I'd ask what it was for. Apparently now the joke's on me for writing this long reply.
The neat little "Thanks for playing" to end your post only show your further arrogance and lack of basic social concepts. You seem to be suffering from some type of antisocial personality disorder judging by the way in which you posed your questions and structured your sentences. Furthermore, your lack of proper punctuation and grammar show that you were rushing haphazardly to prove a point to satisfy a deep rooted egotistical agenda. If I was a psych major (which for the record I am not), I would be apt to say that you probably have a combination of an inferiority and possibly even an Oedipus complex (which would explain the need for immediate gratification). If your attempts were to put me on the spot to answer a rather basic series of questions in regards to the musculoskeletal system - you failed miserably. If you bothered to realize that I answer practically dozens of questions in a 24 hour period, you would understand that I am not obliged to answer each question as if I am having a professional discourse in a lecture hall.
If you wanted to have an actual medical discourse, you should have PM'd me, explained who you were or what was your position, and then asked me your question(s).
