- Our today's topic is development of the diaphragm where we have tried to explain the embryology in details & made it easy. In this tutorial we have described the origin, sources & process of development.
We must have a clear idea about the gross anatomy of diaphragm if we want to understand the embryology. The diaphragm has a central tendon, on both sides it has muscular portions or the dome of diaphragm & on the back it has 2 crus or the crura.
Embryo has 3 germ layers: ectoderm, mesoderm & endoderm. This video shows you diaphram comes from the intermediate layer- mesoderm.
It has 4 developmental sources. They are: septum transversum, pleuroperitoneal fold or pleuroperitoneal membrane, dorsal mesentery of esophagus or esophageal mesentery & the muscular ingrowth of the body wall. We will see how these structures are coming from the mesoderm & forms the diaphragm.
Watch the whole video & you will also see, why the diaphragm is supplied by the phrenic nerve & lower intercostal nerves. As a bonus we will see why skeletal muscles are multinucleated. :)
For everyone's easier access:
00.46: origin of diaphragm
01.06: germ disc- ectoderm, mesoderm & endoderm
02.08: developmental sources of diaphragm
02.40: septum transversum
04.52: descent of septum transversum
06.54: pericardioperitoneal canal, pleuroperitoneal fold or pleuroperitoneal membrane
08.10: dorsal mesentery of esophagus or esophageal mesentery
08.44: somatic or parietal layer of lateral plate mesoderm & splanchnic or visceral layer of lateral plate mesoderm, body cavity, body wall, peritoneum
11.35: pleuroperitoneal fold or pleuroperitoneal membrane
11.57: source of muscle cells of diaphragm, somite
12.26: development of muscular portion of diaphragm
15.06: why diaphragm is supplied by phrenic nerve
15.45: development of crus & median portion of diaphragm
16.04: muscular ingrowth of body wall
16.08: pleuroperitoneal membrane & muscular ingrowth of body wall in early fetal life vs. late fetal period
19.09: why diaphram is also supplied by intercostal nerves
19.42: timeline of development of diaphragm
20.41: what structures give rise to which structures, summery

আসসালামুআলাইকুম মেম
গতকাল ভাবতেছিলাম অনেকদিন হয়ে গেলো মেম রেকর্ড লেকচার আপলোড দেয় না।
আজকে লেকচারটি দেখে খুব ভালো লাগলো।
ধন্যবাদ মেম।
শুভকামনা🥰🥰

Assalamu Alaikum Apu,
I need a little help.
I am having hard time breathing for many years.
Do you know of any doctor who treats the diaphragmatic issues? Can you please suggest me? I am from Faridpur. Thanks.
আসসালামু আলাইকুম ম্যাডম।আমার মেয়ের বয়স ৩ বছর ৪ মাস।তার ডায়াফ্রাম হার্নিয়া হইছে।এটার অপারেশন কি বাংলাদেশে করানো যাবে।একটু বলবেন প্লীজ
ওয়ালাইকুম আস সালাম, জী, ঢাকা শিশু হাসপাতাল এবং বঙ্গবন্ধু শেখ মুজিব মেডিকেল বিশ্ববিদ্যালয় (বিএসএমএমইউ) এ CDH এর চিকিৎসা করানো যেতে পারে। তবে আপনি আরেকটা কমেন্টে ইন্ডিয়ার কথাও জানতে চেয়েছেন। আমি সেটার কথাও উল্লেখ করে দিয়েছি। আর বাংলাদেশেও এটার চিকিৎসা সম্ভব।
ঢাকা শিশু হাসপাতালের একজন ভালো শিশু সার্জন স্যারের ঠিকানা দিলে খুব উপকার হতো ম্যাডম
