Name the appropriate ear structures in their correct sequence Tympanic membrane Malleus Incus Stapes Oval Window Perilymph Vestibular membrane Endolymph Hair cell of the organ of corti Describe how sounds of different frequency pitch are differentiated in the cochlea. The auricle and external acoustic meatus or external auditory canal compose the external ear. The external ear functions to collect and amplify sound which then gets transmitted to the middle ear.

The asymmetric shape of the external auricle introduces delays in the path of sound that assist in sound localization. The auricle ear canal and tympanic membrane are often referred to as the external ear. The middle ear consists of a space spanned by three small bones called the ossicles.

The three ossicles are the malleus incus and stapes which are Latin names that roughly translate to hammer anvil and stirrup. FIG904 The auriculaLateral surface. The external ear consists of the expanded portion named the auricula or pinna and the external acoustic meatus.

The former projects from the side of the head and serves to collect the vibrations of the air by which sound is produced. The latter leads inward from the bottom of the auricula and conducts the vibrations to the tympanic cavity. The outer ear is the external portion of the ear and includes the fleshy visible pinna also called the auricle the ear canal and the outer layer of the eardrum also called the tympanic membrane.

The pinna consists of the curving outer rim called the helix the inner curved rim called the antihelix and opens into the ear. The ear divides into three distinct parts. The outer ear middle ear and inner ear.

The external ear includes the auricle pinna and the external ear canal. Both have a lining keratinized stratified squamous epithelium. The outer ear functions to direct sound energy and vibrations into the ear canal to the tympanic membrane.

Outer ear assists in distinguishing sounds that arise from in front of the listener from those that arise from behind the listener. Middle Ear The middle ear consists of a small 2-cm3 air-filled cavity lined with a mucous membrane. It forms the link between the air-filled outer ear and the fluid-filled.

Outer ear is divided into the pinna and the external auditory meatus. The pinna also known as the auricle is the external ear part that is located and seen on each side of our head. It is made up of cartilage and soft tissue.

This helps in maintaining a particular ear shape and remains pliable. Cochlea semicircular canalsand vestibule. Ear structure not involved with hearing.

Semicircular canals and vestibule. Allows pressure in the middle ear to be. Equalized with the atmospheric pressure.

Pinna auricle external auditory canal and tympanic membrane are the structures that compose the external ear. Pinna or auricle is a funnel shaped organ made of elastic fibrocartilage it function is to collect the sound waves. Structures composing the outer ear.

Structures composing the bony or osseous labyrinth. Ear structures not involved with hearing. This structure allows pressure in the middle ear to be equalized with atmospheric pressure.

This structure vibrates as sound waves hit it. Transmits the vibrations to the ossicles. 1 Structures composing the outer ear 3 answers A.

Sound waves hitting the tympanic membrane eardrum initiate its vibratory motion. Trace the pathway through which vibrations and fluid currents are transmitted to finally stimulate the hair cells in the spiral organ of cortiname the appropriate ear structures in their correct sequence. The outer ear is the portion of the ear that sits atop the skull which is made of flesh and cartilage.

It is the visible part which serves to protect the eardrum. It also collects and guides sound waves into the middle ear. Compositional parts and their functions.

Pinna ear flap The ear flap or pinna is the outer portion of the ear. The outer ear is relatively unprotected and sticks out from the skullThe aneural and avascular properties of cartilage mean that it is unlikely that one is woken up if the ear is folded when being slept on. A change of position means the ear returns to its original shape.

As an external organ the ear must be able to withstand traumaIf the outer ear were made of bone ear fractures would be.
