| teres Ma stretch | 90 degree AB & Ex.Rot |
| latissimus stretch | 0 degree AB & Ex.Rot |
| strong abductor of shoulder | deltoid |
| why deltoid can not start AB of arm? | because angle of pull is parallel w Humerus when arm by side |
| this M is triangular shaped and forms "V" | deltoid |
| this M has identical origin w insertion of trapezius | posterior deltoid |
| anterior & posterior deltoid are antagonists in? | FL/EX & Med/Lat.Rot |
| anterior deltoid O | lateral 1/3 of clavicle |
| middle deltoid O | Lat. acromion of Scap. |
| posterior deltoid O | spine of scapula |
| deltoid Ins | deltoid tuberosity of Hum. |
| anterior deltoid A | FL, horiz.ADD & Med.Rot of Hum. |
| middle deltiod A | horiz. AB to 90 degrees |
| posterior deltoid A | EX, AB & Lat.Rot of Hum |
| deltoid N | Axillary N C5-6 |
| deltoid palp position | seated |
| anterior deltoid stretch | Extr. horiz. AB OR Extr.EX & ADD |
| posterior deltoid stretch | Extr. horiz. ADD |
| which muscle forms anterior wall of axilla | pectoralis MA |
| broad, powerfull M on chest | pectoralis MA |
| parts of pectoralis MA | Clavicular, sternal & costal |
| upper & lower fibers of pectoralis Ma are antagonist? and if - in what movement? | yes, in FL/EX of arm |
| pectoralis MA -clavicular P O | medial 1/2 of clavicle |
| pectoralis Ma - sternal -O | Sternum, cartilages of 6 upper ribs |
