<span>The plasma membrane has a type of protein called intrinsic integrals that are embedded in the thickness of the bilayer and moves laterally in the membrane and act on arriving molecules.

The external ear structure is called the Pinna.
The Pinna helps to channel sound waves into the ear.

I have attached an image of a dog's ear to show you the external structure called the Pinna.
I hope this helps! I'm happy to answer any other questions you might have :)
