Lets c if this ends the Chest debate...

Strong - You'll see head and muscle used interchangeably in the medical community. There is nothing incorrect about saying that the biceps brachii is a muscle group composed of two muscles.

You see..you learn something everyday. I am not in the medical community so I will have to take your word for it. All I know is that in every book I have ever read, the bicecps brachii is considered one muscle. Can you say it is two muscles because of the separate origins?

So it is considered one and two muscles...what is it technically?

Do you have any websites which state that the biceps brachii is two muscles.

A friend of mine had the most awesome physique except for his chest which he couldn't get to grow.

The base of his pectoral in the nipple region was fine, but the top of his chest was the worst. He had no development at all and was completely flat. He battled with it for years. He tried EVERYTHING - went to god-knows-how-many different training specialists. Essentially he was fighting against his own physiology and genetics.

So what did he finally do? He went to the surgeon and got chest implants. He looks great now! LOL.

I tried to fix this problem, not start yet another 2 page thread argueing about it.

btw thats pretty low to go n get chest implants. Im sure some DBol coulda cured that problem lol.

I can find some, but the one you'll see most often is the usage when referring to the quadriceps (same principle here), but I think because the individual heads are so commonly talked about in rehab (interestingly, the most predominant theory, at least that I can find, is that you can't hit an individual head in the quad in any meaningful sort of way).

Let me see if I can quickly find one for you. Personally, I find the dual terminology confusing myself. I think it is because of the different origin though, for example you could cut off one of the heads/muscles in the biceps and still have a thing there that was in essence a muscle unto itself. Ok, I'm rambling. I'll check around.

Strong - here this quote is from Gray's in which the refer to the quad as one muscle and many muscles in the same sentence:

"The Quadriceps femoris (Quadriceps extensor) includes the four remaining muscles on the front of the thigh. It is the great extensor muscle of the leg, forming a large fleshy mass which covers the front and sides of the femur. "

In their sections on the biceps and the triceps, I could only see the groups referred to as heads. I told you, it's confusing. I can't seem to find a clear answer, so I just consider that they get used interchangeably. If anyone else has insight, maybe we can all learn something more on this.

Whats up Marshall....I was referring to the bicpes brachii.

I never assumed that the quadracep was a single muscle. I always thought it was a muscle group.

But you do see it referred as both a muscle group and as a muscle itself.

Plus all four do share the same insertion.
" The tendons of the different portions of the Quadriceps unite at the lower part of the thigh, so as to form a single strong tendon, which is inserted into the base of the patella "(Gray)

Similar to the bicep which has two origins and one insertion.

Valid point...maybe it has something to do with having separate origins.

Do you consider the pectoralis major to be two muscles, since it has two heads? But lacks "separate" origins.

the pectoralis major HAS seperate origins (sternum, clavicle), its insertion point is common (humerus).

Whats the big deal? I say do whats best for you. I personally, do all incline movements and my chest has transformed in shape over the years. I now have thick muscle filling in the sternal, clavicle, and outer areas. From a personal view, I think flat pressing is way over-rated.

 

[strong island]

Misunderstanding....I am saying that there is no distinct separation. It is one long origin that encompasses both the sternum and clavicle.

As opposed to the bicep and quad which have distinct separate origins.
