Registered nurses work in hospitals, physiciansâ offices, home healthcare services, and nursing care facilities.
The basic function of the outer ear or pinna is to protect the eardrum (tympanic membrane). The outer ear also functions to collect sound waves to the eardrum through the ear canal. The second component of the external ear is the auditory ear canal or meatus.
Ear blockage or blocked ear is a clogged-like feeling in the ear due to a problem in the external ear canal or the middle ear. The ear consists of the outer ear, middle ear and inner ear. The outer ear has the large cartilaginous part called the pinna. The pinna leads into a short canal, at the end of which is the eardrum or tympanic membrane. The eardrum is a thin membrane that separates the external ear from the middle ear.
