Thread: bet about pec heads with my friend

u win if u click on the sternal head u'll find it's another muscle... i don't know really but i guess nobody will win cause he'll tell you look that's it there's more than one head and u'll tell him look at red shaded area just one..

Actually, you lose.

There is the pectoralis major, which is the large triangular muscle extending from the sternum to the humerus. Then there is the pectoralis minor, which is beneath the pectoralis major and attached to the coracoid process of the scapula.

Sorry. Hope you didn't bet anything good.

I mentioned above that he was talking about that the pectoralis major was two different muscles...

Edit: I think you should re read what i posted... I was arguing that the sternal part of the pectoralis major was one muscle, he said two.

I think she posted without reading.....that is very common here.

Yes, the sternal head is only one muscle.

Pervert.

No you didn't.

And both the pectoralis major and the pectoralis minor are attached to the sternum. And they are divided horizontally.

I read what you wrote very carefully. No reference to the "pectoralis major" was made.

You made a reference to the "main sternal head", but both muscles originate in the sternum. And the pectoralis minor is in no way attached to the clavical.

I think you just can't stand to lose a bet.

VanessaNicole

She's right.

there both right!

his friend thinks that the major is divided horizontally, and is wrong. st240 said that the pec major is one muscle and is right. vanessa pointed out that thir is also a pec minor behind the major and is right!

The Pectoralis major (Fig. 410) is a thick, fan-shaped muscle, situated at the upper and forepart of the chest. It arises from the anterior surface of the sternal half of the clavicle; from half the breadth of the anterior surface of the sternum, as low down as the attachment of the cartilage of the sixth or seventh rib; from the cartilages of all the true ribs, with the exception, frequently, of the first or seventh, or both, and from the aponeurosis of the Obliquus externus abdominis.

The Pectoralis minor (Fig. 411) is a thin, triangular muscle, situated at the upper part of the thorax, beneath the Pectoralis major. It arises from the upper margins and outer surfaces of the third, fourth, and fifth ribs, near their cartilage and from the aponeuroses covering the Intercostalis; the fibers pass upward and lateralward and converge to form a flat tendon, which is inserted into the medial border and upper surface of the coracoid process of the scapula.

I thought the origin of the pectoralis minor was on the ribs, but not the sternum? The sternal head of the pectoralis major originiates on the sternum as well as certain ribs, though I forget which ribs exactly.

You better whip out some semantics to win this bet I think, though I have a feeling your friend had no idea what the pectoralis minor is; most people don't.

Show me where it says "pectoralis major" in his original post, and I'll go take remedial 5th grade reading.

They actually overlap somewhat. But the distinction between the major and minor occurs between the 3rd and 4th intercostal space.

Clavical/Sternal heads = Pectoralis major heads

Originally Posted by ST240

There is no "clavicular head" of the pectoralis major, it's lateral most point of insertion is the humerus. And it's medial point of insertion is the sternum, not the clavical.

And the pectoralis minor also has a medial point of insertion at the sternum (what you call a sternal head). There is a sternal head of the p. major and a sternal head of the p. minor.

Anyway, I'm not into symantics.

Pectoralis Major (Sternal Head)

Pectoralis Major (Clavicular Head)

My dear, you have stumbled into a nest of bodybuilding lawyers. Precision is key.

The pectoralis minor sits underneath the pectoralis major. Also, there is definitely a sternal and clavicular head to the pectoralis major. The clavicular head actually orginiates on the clavicle, hence the name.

The pectoralis minor does not orginiate at the sternum, and there are not separate heads to the pectoralis minor.

Looks like nobody can show you anything and you are incapable of reading with some common sense.
