the ear is made up of what cartilage
The Outer Ear. Parts of the Ear: Outer Ear | Middle Ear | Inner Ear. The outer ear consists of the pinna, or auricle, and the ear canal (external auditory meatus). The pinna â the part of the ear that we see on each side of our heads â is made of cartilage and soft tissue so that it keeps a particular shape but is also flexible. The pinna serves as a collector of sound vibrations around us and guides the vibrations into the ear canal.
