Sir can you please tell me the proper definition of eardrum? Plssss sirrr

[@user_sigma0]

Ear drum( Tympanum) is a membrane which separate outer ear from internal ear.

[@kholamrafique1866]

sir apki is lecture me ik bt samajh nhi aai ap ny kaha ky ear drum external or middle ear ko separate karti hy...but ksy karti hy mujhy ye samajh nhi aaya wo to bilkl end par hoti hy to wo inko ksy separate kary gi...please clear

[@ChemistryPlusOfficial]

Not at end ear drum is present between external ear and Middle ear

Which protect the ears In ki protection kese hoti he

[@ChemistryPlusOfficial]

Skull bones protect the middle and inner part of ear externa ear is protected just by skin covering

[@spozhmaikakar7422]

Well done sir 👍

[@SajjadKhan-lj7xj]

Sir can you plz tell me how to remember something for long time... 🙁

[@ChemistryPlusOfficial]

Its not simple...keep your brain healthy...and repeat things in a week or 15days

How maintain body balance example btye

[@insharaali6619]

Sir has replied to another comment asking the same question. You can check in the comment section of this video and you'll find your answer.

[@user-vq7db8iv1y]

Sir ear body balance may kesay role play karta ha

[@ChemistryPlusOfficial]

The ear, specifically the inner ear, plays a crucial role in maintaining body balance. The structure responsible for this is the vestibular system, which comprises two main parts: the semicircular canals and the otolith organs. Here's how they work: Semicircular Canals: There are three semicircular canals oriented at right angles to each other: horizontal, anterior, and posterior. These canals are filled with a fluid called endolymph. When you move your head, the fluid inside the canals shifts. This movement of the fluid bends hair cells (sensory receptors) located within the canals. The bending of these hair cells sends electrical signals to the brain, indicating the direction and speed of head rotations. Otolith Organs (Utricle and Saccule): These organs detect linear acceleration (like when you're in an elevator) and the force of gravity. They contain tiny calcium carbonate crystals (otoconia) that sit on top of a gel-like layer. When you tilt your head or move vertically, these crystals shift, bending the hair cells below. This bending action triggers electrical signals sent to the brain, helping you sense your position relative to gravity and linear movements. The signals from the vestibular system are sent to the brain, primarily the cerebellum and the brainstem. The brain integrates this information with signals from your eyes (visual input) and from sensory receptors in your muscles and joints (proprioceptive input). This integrated information helps you maintain balance and orient yourself in space. If the vestibular system malfunctions (due to infections, injuries, or other conditions), it can lead to dizziness, vertigo, and balance disorders.

[@hassanzada7209]

I like your lecture

[@aaliaarshad7966]

sir ear maintain the body balance but how ?????????? (example)??????????????

[@ChemistryPlusOfficial]

Its separate topic.... Position feedback from the inner ear Each semi-circular canal has a different orientation to detect a variety of movements such as nodding or rotating. Movement of fluid inside the canals caused by head movement stimulates tiny hairs that send messages via the vestibular nerve to the cerebellum.
