They help us hear sounds, and transfers the sounds into the brain.
Yes they can be. It's the main cause for ear infections. For instance, if a child has an eye infection and they rub their eye, then stick that finger in their ear, they can spread the infection to their ear and vice versa.
The pinna (which means "wing" in Latin).
The ear has three main parts: the outer ear, middle ear, and inner ear. The outer ear consists of the pinna and ear canal, which collect sound waves. The middle ear contains the eardrum and ossicles, which amplify sound vibrations. The inner ear houses the cochlea and vestibular system, playing crucial roles in hearing and balance.
Sound waves are gathered by the outer ear, which consists of the pinna and ear canal. The pinna acts as a funnel to capture sound waves and funnel them into the ear canal, where they then travel to the middle ear.
Pinna
outer ear
The outer ear consists of the "pinna" and the "external auditory meatus." The "tympanic membrane" is the border of the "middle ear." Notice that the diagram incorrectly labels the "pinna" as the outer ear. [The diagram is posted online without either a source or a copyright notice.]
The different Parts of the Human EarThe three major parts of the human ear are the outer ear, the middle ear and the inner ear.Outer Ear: The outer ear consists of the following two parts:Ear Flap (Pinna)Ear Canal (Meatus)Middle Ear: consists of the following parts:Eardrum -HammerAnvil (Incus)Stirrup (Stapes)Inner Ear (Labyrinth): The inner ear comprises the following parts:CochleaSemicircular Canals -Auditory Nerve
The ear consists of three main parts: the outer ear, the middle ear, and the inner ear. The outer ear includes the ear canal and the visible part of the ear (pinna). The middle ear contains the eardrum and three small bones (ossicles) that transmit sound vibrations. The inner ear houses the cochlea and semicircular canals, which are responsible for converting sound waves into electrical signals that the brain can interpret.
the ear
The outside of the ear, called the pinna or auricle, is made of cartilage not bone. The bones (auditory ossicles) are located in the middle chamber of the ear.
the outer part of the ear
the pinna funnels sound waves.
