Question about the tendon that attaches to the pubic tubercle


I’m trying to figure out not only what this feature is, but also its morphology. I’m talking about the slight protrusion that that appears to occur at the pubic tubercle, or perhapse the anterior section of the ischium, I’m not sure, and then dissapear into the greater mass of the inner thigh. I can’t tell if it reaches the sartorius in any of the actual photo references I have seen.

Some anatomy books, this seems to be the Adductor Longus, in others it is illustrated as the gracillis. In some cases it appears to be a triangluar tendon from an entirely different muscle, set between the gracilis and Adductor Longus. I do not think it is the adductor magnus, though in many illustrations this muscle does show through as a triangular wedge between the longus and gracillis. The feature I speak of appears to be different.

It’s very noticible during abduction of the leg, yet it seems as though this anatomical feature just gets glanced over (no jokes, please) by any texts on the subject.

I’ve looked at countless anatomy books and just about every online resource I can find, but so far have found nothing conclusive.

I’d appreciate it if someone could help me out, though I wouldn’t be surprised if everyone else gets stumped as well.

Thanks in advance.


Andre Jackson,

Have you looked here?


Adductor Longus:


These are muscles, however, you said you are looking for tendons…




Hi, as a matter of fact, yes. I would assume I have exhausted every resource available on the internet. I should note I am only assuming it is one of these muscles. It could be both combined, or maybe something different.

Either way, thank you.

edit: It’s such a thin protrusion I assume it is a tendon from one of these muscles, rather than the entire muscle.


I’m assuming it’s the tendon of the adductor longus?

    From [Gray's Anatomy Online](

The Adductor longus (Fig. 433), the most superficial of the three Adductores, is a triangular muscle, lying in the same plane as the Pectineus. It arises by a flat, narrow tendon, from the front of the pubis, at the angle of junction of the crest with the symphysis; and soon expands into a broad fleshy belly. This passes downward, backward, and lateralward, and is inserted, by an aponeurosis, into the linea aspera, between the Vastus medialis and the Adductor magnus, with both of which it is usually blended.

[left]Could this account for the differences you are seeing?

Variations.—The Pectineus is sometimes divided into an outer part supplied by the femoral nerve and an inner part supplied by the obturator nerve. The muscle may be attached to or inserted into the capsule of the hip-joint. The Adductor longus may be double, may extend to the knee, or be more or less united with the Pectineus. The Adductor brevis may be divided into two or three parts, or it may be united to the Adductor magnus. The Adductor magnus may be more or less segmented, the anterior and superior portion is often described as a separate muscle, the Adductor minimus. The muscle may be fused with the Quadratus femoris.




This actually explains a lot. Thank you very much.

Is this illustration you have hosted on photobucket also from Grey’s anatomy? Somehow I missed it.

Either way, it appears I was arrogant in assuming my search was as exhaustive as it could have been.

The illustration itself is pretty much enough, but the explainations of variations in the adductor muscles also accounts for a great deal of confusion I have had.

Thanks again.


Andre Jackson,

No problem! A bit of sleuthing is fun. :slight_smile:

The image is actually from Grant’s Atlas of Anatomy by Agur and Dalley. I would recommend it, it is a very nice book. :slight_smile:




I’m buying it first chance I get. If that illustration is indactive of the rest of the book’s quality, then it looks like it’s a far far better reference than Netter.


Netter is a bit dated, but he sort of set the standard. :slight_smile:

Other great books (as recommended by a medical illustrator who posts to this board) are:

McMinn’s Color Atlas of Human Anatomy and Color Atlas of Human Anatomy. Both have photos vs. just illustrations and are quite clear.

Cheers, :slight_smile:



I just got my copy of Grant’s Atlas of Anatomy, and you were right about the quality of the illustrations but I was somewhat dissapointed at the lack of any charts of skin tension lines/langer’s lines or whatever they are called. The illustrations of the various aponerosis and fascia were pretty good, and since there is a lot of overlap between skin surface wrinkles and the lines of the fascia I might be able to make due, but I was hoping for a little more.

You wouldn’t happen to know of any of the other books you mentioned have emphasis on the dermis, would you? Or any books at all with emphasis on wrinkles.

I have a couple of books with brief mention of langer’s lines, but most are limited to including a single illustration, like in the case of Sarah Simblet’s Anatomy for the Artist, accompanied usually by a brief explaination of what I’m supposed to be looking at, but nothing particularly in-depth. It always seems the skin gets neglected in anatomy books.

I had been considering buying one of those huge plastic surgery atlases or something, but considering the rather prohibitive price, I was hoping for a specific recomendation, if you happened to know.


Andre Jackson,

The real expert on books whom you might ask is David Ehlert, a Medical Illustrator with an Anatomy Thread here:

Anatomy Thread of redehlert:

He would probably have the best recommendation for you. Feel free to post to his thread, he’s subscribed. :wink:

Cheers, :slight_smile:



Great, thanks. I’ll make sure and do that when I go through the entire thread. Just at a glance I’ve seen some good resources for general anatomy.
