Question | Answer |
3-sided bone situated between 1st & 7th ribs | Scapula |
ONLY upper arm bone | Humerus |
Hip bone | Illium |
Large, triangular "tailbone"; wedged between two hip bones; back wall of pelvic girdle | Sacrum |
The remains of a tail; Useless | Coccyx |
12 curved bones designed for mechanical breathing | Ribs |
Spaces between the ribs | Intercostal Spaces |
Small, thick, powerful muscle located in the groove above the scapula's spine | Supraspinatus |
Highest insertion point of the four rotator cuff muscles | Supraspinatus |
If the Deltoid went dead, this muscle could abduct the arm on its own | Supraspinatus |
Helps hold arm away from the side of body as in holding/carrying a bag/suitcase | Supraspinatus |
Top member of the Rotator Cuff; anti-dislocation Stabilizer | Supraspinatus |
Below the scapula spine ridge | Infraspinatus |
This muscle cannot be found in primitive animals | Teres Minor |
Located on Posterior side of scapula blade, under Deltoid; tow members of Rotator cuff | Infraspinatus/Teres Minor |
Fuse together and attach on BACK head of Humerus ball | Infraspinatus/Teres Minor |
Prevents upward displacement of Humerus | Teres Minor |
Prevents backward displacement of Humerus | Infraspinatus |
Under the scapula | Subscapularis |
Sandwich-like muscle between shoulder blad and ribs | Subscapularis |
Insterted on the front of the humerus head ball | Subscapularis |
Prevents forward dislocation | Subscapularis |
THE major prime-mover in forward rotation | Subscapularis |
The shoulder pad muscle | Deltoid |
Comes into play ANYTIME the arm moves | Deltoid |
Its 3 heads converge into one thick tendon that attaches to a "knot" called the Deltoid Tuberosity | Deltoid |
Head of Deltoid responsible for flexion and horizontal adduction | Anterior Head |
Head of Deltoid responsible for arm abduction out to the side | Middle Head |
Head of Deltoid responsible for extension/hyperextension, and backward rowing | Posterior Head |
Large, broad, Flat, triangular shaped muscle. Largest muscle in terms of square inches | Latissimus Dorsi |
Along with Subscapularis, makes up the back of the armpit | Latissimus Dorsi |
Has 4 origins:T6-T12, L1-L5, Sacrum, and Illium | Latissimus Dorsi |
Even though its a "back" muscle, it works the shoulder, not the spine. | Latissimus Dorsi |
The "Pulling & Climbing" muscle. The "swimming" muscle | Latissimus Dorsi |
A round, thick muscle on the upper back that's Lat's little brother | Teres Major Muscle |
Large, broad flat muscle just beneath the skin | Trapezius |
Anatomically has 3 different parts with different nerves to each. | Trapezius |
Both a necka and shoulder muscle | Trapezius |
This is sore after carrying a suitcase all day when traveling. | Trapezius |
Flat, parallel muscules located in the middle of the back under the Trapezius | Rhomboids |
Draws the scapula toward the spine, such as rowing | Rhomboids |
Powerfully pulls the shoulder blade downward when the arms are overhead | Rhomboids |
Very strong flat, strap-like muscle of parallel fibers at the back side of the neck (found only in humans) | Levator Scapula |
Prime mover in lifting, raising, or "shrugging" the scapula upwards | Levator Scapula |
Strong neck stabilizer when doing sit-ups or push-ups | Levator Scapula |
Large, flat, triangle shaped chest muscle; forms the front of the armpit | Pectoralis Major |
