Things to dissect and see: longus colli dorsalis
September 15, 2011
Okay, special dissection post, coming to you live from the Symposium of Vertebrate Palaeontology and Comparative Anatomy in Lyme Regis, on the Jurassic coast of England, well past my bedtime. First, check out this comment from Neil and see the linked image of some neck muscles in the anhinga. Here’s a small version I’m swiping. There are a couple of short, single-segment muscles shown, but the big long ones in this image are longus colli ventralis (on the ‘front’ or ‘bottom’ of the neck) and longus colli dorsalis (on the ‘back’ or ‘top’).
Now, grok these photos of the same dorsal muscle. Or muscle group, if you prefer. Note that in all cases shown here and in the link–anhinga, rhea, and turkey–the muscle inserts on the anterior cervical vertebrae, and not on the skull.
In Meleagris (turkey):
The rhea was dissected by Vanessa back at Western a couple of weeks ago, the turkey by me on Mike’s dining room table on Monday. Full story to follow…at some point.
In the meantime, go buy your own turkey and cut up its neck. It’s cheap and you’ll learn a ton.
