Dr Adel Bondok Anatomy Lectures. Anatomy of the Ear. Link to the Lecture: drive.google.c... NOTE that the anterior semicircular canal is usually called the superior semicircular canal.
I wonder why such a detailed lecture has no many views atherwise those who follow u up are the luckiest among all other medical students ❤ best professor of anatomy
Sir you are a best mentor..... The way you teach us is very simple and amazing....... We can understand and memorize each and everything very easily by listening to your lectures..... Thank you so much 💕 جزاک اللّہ خیرا 💕
Thank you sir ...love from Pakistan... ur lectures satisfied me so much alhamdulillah... inshallah I may secure position again in this upcoming proff as in previous...pray for me
What is the function of the pinna? I don't believe it is for the collection of sound to funnel it to the ear drum. I would like to know if you are aware of its physical function, or only what is said in major medical books (from what I know about these, it is a missing component and a major oversight).
Wow ⁉️ I like it. Think out of the box 📦. The human ear pinna is a vestigial organ, which was used for collecting sound and was movable in ancient days. The flexibility of the human pinna is vestigial now but still functional in monkeys and apes and in other animals with long ear like rabbits and donkeys. The skin of the pinna is rich in sebaceous glands, which serve to protect the ear from cracking. The external auditory canal skin contains specialized ceruminous glands, which produce cerumen (earwax) that may hinder or repel the entry of insects and debris through the external acoustic meatus.
@@AdelBondok Thank you for your wonderful reply, but this isn't quite what I expected. From what you say it could well be true, however, the purpose of the pinna is what I was hoping you would share. Here's my version, and after seeing a few, unfortunately, very few videos sharing the same physics about them as I realised what they were for from my own critical thinking after I realised how to recreate recordings of binaural audio, by realising that, I realised how the pinna worked, and it is nothing to do with trumpeting the sounds down the ear canal.. I think most of the books out there that describe the pinna as a physical thing to collect the sound and direct it down the audiory canal is actually incorrect. And, the majority of people who then explain what it is simply take the paper's word for it, so it becomes the dogma from where we all get informed upon. The pinna is NOT a collecting device but a binaural infusion device for inducing different tones of sounds given a particular direction, a unique tone is made at any given angle due to the shape of the pinna where the brain then can determine where the direction of the sound is coming from. The pinna is the ONLY organ (as far as I know) that you can actually see how it works, as long as you comprehend the principles of physics, due to the shapes of the pinna causing differential tones depending upon the angle at which it arrives.. Now then, does this float your boat? I actually manufacture binaural microphones, which are microphones that have ears on them, so that I can clone a recording of how we hear things, and when played back through headphones, to separate the left and right channels correctly, you would perceive binaural audio as if you were there in person hearing the sounds for yourself. It is quite a shame that this function is not really taught in the education system, some tutors do state this, but they are as rare as hens' teeth so to speak. Looking forward to your reply, as it's 1:50am here, it will be a while before i reply :O)
@@sr3d-microphones It is really amazing how you presented the function of the pinna. It seems that you did a lot of research on it> I learned a lot from your reply. Now, I realized why the surface of the auricle (pinna) is not flat but curved with grooves and is different from animal to animal. As you said: the pinna is a binaural infusion device for inducing different tones of sounds given a particular direction, a unique tone is made at any given angle due to the shape of the pinna where the brain then can determine where the direction of the sound is coming from. Binaural hearing is what allows humans and other animals to pinpoint the source location of a sound. Every human and animal has a uniquely shaped ear. The shape of our ears and the related HRTF (Head Related Transfer Function) produce a very specific signature for any given sound. The circumference of our heads, the material of clothing we wear, the distance from the sound source, the shape and composition of materials around us also help form the sounds we hear every day. Thank you for clarifying and this is a very special field of education either we are ignoring it or neglecting it medical education. It belongs to the physics more than to medicine.
@@AdelBondok thank you. The HRTF is actually not required, as the ear does all the work, though having a dummy head microphone (a binaural recording device maybe more appropriate) will have a slightly better perception experience. Please do check out some of my binaural examples on my channel, there are the tube type, and the dummy head type, plus a few others. Obviously everyone’s ears are slightly different so some binaural confusion could occur- however, this experience should be perceived outside of your head within your environment.
Thank you again… Sir one question: on which wall of the tympanic cavity would be the hiatus for the lesser petrosal nerve? (Which arises from tympanic plexus having fibers from inferior salivatory nucleus)?
After arising in the tympanic plexus, the lesser petrosal nerve passes through the hiatus for the lesser petrosal nerve in the anterior wall of the middle ear on the anterior surface of the petrous part of the temporal bone. It travels across the floor of the middle cranial fossa, then exits the skull via foramen ovale to reach the infratemporal fossa.
I have had my pallet broken shatterd an for thr last 3 year ive been dealing with liquid coming threw my nose today a big glass like ruby came out my ear what shoil i do
