whats a syrinx? i have the book def. in front of me and it states that its at the posterior end of the trachea...also known as the voice box, but i keep searching it on wikipedia and google so i can see a picture of it but nothing similar to it comes up...and by the way its avian anatomy...i think it isnt spelled correctly, can someone give me the proper term...thanks
 
I'm currently cramming before my anatomy exam, so I have Dyce's "Veterinary Anatomy" open on my desk. According to it:

"The syrinx is formed by the terminal part of the trachea and the beginning of the primary bronchi...
The lateral and medial walls of the initial segments of the bronchi are membranous and produce the voice when causes to flutter. A small paired muscle, sternotrachealis, pulls the trachea toward the syrinx and aids in vocalization."

There is a schematic drawing as well, although it's hard for me to orient it's actual location.

Back to studying!
 
Your welcome; Im home studying too. Organic Chem...Ughhhhhh😱

And waiting/ watching to see if my lab partner got into VA-MD!
 
Looks like you may have gotten the info you need, but in case you just wanted a *really* simple explanation... You know how the vocal cords ("voicebox") in mammals are up at the top of the trachea, just beyond the epiglottis? Well, in birds, the analogous structure is right down at the end of the trachea, where it branches into the two main bronchi.

Fun clinical fact: Because of the distal placement of the syrinx, birds can vocalize while intubated!
 
That's an interesting fact kate_g!
