Chicken Embryo Gastrointestinal Tract Motility

<html5media height="370" width="600">File:Chicken GIT peristalsis movie 01.mp4</html5media>

MP4

Chicken embryo (E 8) jejunum motility well before it is required for nutrition. Emergence of an uninterrupted circular ring of smooth muscle correlated with the appearance of propagative contractile waves, at E6 in the hindgut and midgut, and at E9 in the caecal appendix. We show that peristalsis at these stages is critically dependent on calcium and is not mediated by neurons as gut motility is insensitive to tetrodotoxin and takes place in the hindgut in the absence of neurons.
