outer ear
The external ear refers to the entire structure outside the ear canal, including the auricle (pinna) and ear canal, while the outer ear specifically refers to the visible part of the external ear, which is the auricle.
The external ear is composed of two main structures: the pinna (auricle) and the external auditory canal. The pinna is the visible part of the ear that helps collect and direct sound waves towards the ear canal. The ear canal is a tube-like structure that extends from the pinna to the eardrum, and it is lined with skin and fine hairs to help trap debris and protect the ear.
The external ear ends at the ear canal, also known as the external acoustic meatus, which extends from the outer ear to the eardrum.
