In anatomy, the scapula (plural scapulae or scapulas) or shoulder blade is the bone that connects the humerus (upper arm bone) with the clavicle (collar bone). Like their connected bones the scapulae are paired, with the scapula on the left side of the body being roughly a mirror image of the right scapula. In early Roman times, people thought the bone resembled a trowel, a small shovel. The shoulder blade is also called omo in Latin medical terminology.
The scapula forms the back of the shoulder girdle. In humans, it is a flat bone, roughly triangular in shape, placed on a posterolateral aspect of the thoracic cage.
It is a wide, flat bone lying on the thoracic wall that provides an attachment for three different groups of muscles. The intrinsic muscles of the scapula include the muscles of the rotator cuff- the subscapularis, teres minor, supraspinatus, and infraspinatus. These muscles attach to the surface of the scapula and are responsible for the internal and external rotation of the glenohumeral joint, along with humeral abduction. The extrinsic muscles include the biceps, triceps, and deltoid muscles and attach to the coracoid process and supraglenoid tubercle of the scapula, infraglenoid tubercle of the scapula, and spine of the scapula. These muscles are responsible for several actions of the glenohumeral joint. The third group, which is mainly responsible for stabilization and rotation of the scapula, consists of the trapezius, serratus anterior, levator scapulae, and rhomboid muscles and attach to the medial, superior, and inferior borders of the scapula.
The human body is the entire structure of a human being and comprises a head, neck, trunk (which includes the thorax and abdomen), arms and hands, legs and feet. Every part of the body is composed of various types of cells, the fundamental unit of life.
At maturity, the estimated average number of cells in the body is given as 37.2 trillion. This number is stated to be of partial data and to be used as a starting point for further calculations. The number given is arrived at by totalling the cell numbers of all the organs of the body and cell types. The composition of the human body is made up of a number of certain elements including carbon, calcium and phosphorus.
The study of the human body involves anatomy and physiology. The human body can show anatomical non-pathological anomalies known as variations which need to be able to be recognised. Physiology focuses on the systems and their organs of the human body and their functions. Many systems and mechanisms interact in order to maintain homeostasis.

Motherfucker, I came to get mine
I when its ready, have that money on time
Or out comes my nine, put it to your mind
and blow that shit, on some real Poet shit
My clique be G.I. Joe and shit
Big guns and army pants
That where I spit my advance
so y'all niggas ain't got a chance
Fuck who's the nicest,
I got semi-automatic devices, to handle all crisis's
and while I'm at it nigga show me where that ice is
And don't forget you life is priceless
'Cuz I don't give a fuck about you
Smack the shit out'choo
And look at'cha crew like what'cha gonna do
I'm not your average rapper, I damage rappers
Black, white or spanish rappers
I don't descriminate, I just eliminate
Runnin with real motherfuckers that you know is tryin split a cake
[Chorus]
Jump out the Cadillac toting the mack, wavin a school flag
Throwin up the S with suit and doo-rag
Keep it ghetto, these Screwball niggas keep it wild and mello
Don't make us sneak up on you with that cold piece of metal
And push your wig down to the gas pedal, thats settled
We QB rebels we attack on all levels
We'll decrease ya red blood cells if all else fails
Chop up your body send ya frame through the mail
Now where that tank when you still tote gats that ancient
Went from juvenile to a dope delinquent
We thugged up, stay up in a low hold drugged up
School ballers actin out of order get slugged up
I love twisting phillies, love gettin drunk silly
Love gettin pussy, love gettin richer than Willie
I detest y'all, fuck the police they just arrest y'all
Fuck the mayor, fuck his wife, and his desk job
[Chorus]
Fist balled up, teeth jagged edged bald heads, spark you
Don't be surprised if I pop duke
Discombobulate, now this is hard to take?
Set it then, if you do you'll regret it to the end
Your destiny's in my hands motherfucker
Didn't studder, utter, or mutter
You're heart thudded Kool-Aid
?This blue raid? adversary shook
I'm ready like a book waitin to be read
My dogs waitin to be fed
My stem is waitin to see dead
Stomach full of tape worms hungry as fuck
Screwball push 'em up, push 'em up
Southeast big skinned it, power moves unlimited
Universal, rhymes been past curfew
Our men will hurt you, lay you in dirt too
Flame thrower, extraordinary fame holders
Same chick on the same shoulder
Same clip til his brains blow up
Screwball, the name's heard of
