teres Ma A	Ex, ADD & Med.Rot of Hum.
teres Ma N	Lower scapular N C5-6
teres Ma palp. position	prone w arm of table
infraspinatus is synergist w ?	Teres MI in Lat.Rot
this muscle is flat, "facet"- like	infraspinatus
2nd most commonly injured rotator cuff Muscle	infraspinatus
infraspinatus O	infraspinous fossa of Scap.
infraspinatus Ins	greater tubercle of Hum.
infraspinatus A	Lat.Rot & Ex of Hum.
infraspinatus N	subscapular N C5-6
infraspinatus palp. position	prone w arm of table
infraspinatus Stretch	Extr. horiz ADD & Int.Rot of arm
teres MI stretch	Extr. Horiz. ADD & Int.Rot of arm
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
pectoralis MA Ins	Lat. lip of bicipital groove
pectoralis MA - general A	ADD, horiz, ADD & med.Rot of Hum
pectoralis MA - clavicular - A	FL of Humerus
pectoralis MA - sternal - A	EX of Humerus
pectoralis MA -clavicular - N	Lat. pectoral N C5,6,7
pectoralis MA sternal- A	Med.pectoral N C8, T1
pectoralis MA palp position	supine & arm AB
"door stretch" stretches ?	pectoralis MA
pectoralis MA book stretch	arm by side, --> Ex Rot, or in horiz AB
pectoralis MA -upper- stretch	EX of arm
pectoralis MI - lower- stretch	full AB of arm
how to palpate antagonistic movements of pectoralis MA?	Supine, arm toward ceiling, ask FL/EX w resistance
triceps B -origin of name	latin" 3 heads"
only Muscle on posterior arm is?	triceps brachii
origin of long head of triceps B	infraglenoid tubercle of Scap.
origin of long head of biceps brachii	supraglenoid tubercle of Scap.
triceps B -long h. -O	infraglenoid tubercle of Scap.
triceps B - Later. H. -O	poster. humerus ABOVE spiral groove
triceps B - Medial h- O	poster. Humerus Below Spiral groove
