What is the anatomy and physiology of the ear?

In summary then, anatomically, the ear consists of a sound conducting mechanism and a sound transducing mechanism. The sound conducting mechanism has two parts, the outer ear consisting of the pinna and ear canal, and the middle ear consisting of the tympanic membrane.

What are the 10 parts of the ear?

The parts of the ear include:

  • External or outer ear, consisting of: Pinna or auricle. This is the outside part of the ear.
  • Tympanic membrane (eardrum). The tympanic membrane divides the external ear from the middle ear.
  • Middle ear (tympanic cavity), consisting of: Ossicles.
  • Inner ear, consisting of: Cochlea.

What is the anatomy of the ear?

The outer ear consists of skin and cartilage, called the auricle, or pinna, and the ear canal. The ear drum, or tympanic membrane, is a thin membrane that separates the outer ear from the middle ear. The middle ear is an air-filled chamber containing three small bones called ossicles.

What are the physiology of hearing?

Hearing starts with the outer ear. When a sound is made outside the outer ear, the sound waves, or vibrations, travel down the external auditory canal and strike the eardrum (tympanic membrane). The ossicles amplify the sound. They send the sound waves to the inner ear and into the fluid-filled hearing organ (cochlea).

What is the outer ear called?

External or outer ear, consisting of: Pinna or auricle. This is the outside part of the ear. External auditory canal or tube.

What is the physiology of hearing?

Hearing is the process by which the ear transforms sound vibrations in the external environment into nerve impulses that are conveyed to the brain, where they are interpreted as sounds. …

What are the two types of physiology?

According to the classes of organisms, the field can be divided into medical physiology, animal physiology, plant physiology, cell physiology, and comparative physiology. Central to physiological functioning are biophysical and biochemical processes, homeostatic control mechanisms, and communication between cells.

What is the importance of anatomy and physiology?

Anatomy and Physiology provide basic knowledge about the human body. It helps in clearing the fundamental concepts as to how our bodies function. With the help of the classes of anatomy and physiology, one gets to learn not only the theoretical concepts but practical functionalities of the human body too.

What are the functions of the ear anatomy?

The ears are organs that provide two main functions — hearing and balance — that depend on specialized receptors called hair cells. Hearing: The eardrum vibrates when sound waves enter the ear canal.

What are the 3 main parts of the ear?

The ear is made up of three parts: the outer, middle, and inner ear. All three parts of the ear are important for detecting sound by working together to move sound from the outer part through the middle and into the inner part of the ear. Ears also help to maintain balance.

What are the anatomical parts of the ear?

The anatomy of the ear consists of the outer, middle, and inner ear. The shape and form of the outer ear help direct sounds to the eardrum. The middle ear contains the three small bones that pass along the vibrations reaching the eardrum to the inner ear.

What is the structure and function of the human ear?

Human ear. The outer ear consists of the visible portion called the auricle, or pinna, which projects from the side of the head, and the short external auditory canal, the inner end of which is closed by the tympanic membrane, commonly called the eardrum. The function of the outer ear is to collect sound waves and guide them to the tympanic membrane.
