Where are the hearing receptors located?
The cochlea The cochlea is filled with two fluids (endolymph and perilymph), inside the cochlea is the sensory receptor — the Organ of Corti — which contains sensory cells with hair-like structures (hair cells) that are the nerve receptors for hearing.

Cochlea. This contains the nerves for hearing. Vestibule. This contains receptors for balance.
Where are the receptors for hearing located quizlet?
the sense organ in the inner ear containing the receptors for hearing and located within the cochlear duct of the cochlea; contains the receptors for sound stimuli.
Where are the receptors for hearing located in the spiral organ?
the cochlea The organ of Corti, also known as the spiral organ, is the receptor organ for hearing, located in the cochlea (housed inside the scala media). It is a strip of sensory epithelium made of hair cells which act as the sensory receptors of the inner ear.
What type of receptors are located in the ear quizlet?
What type of exteroceptors are located in the ear? *Hair cells in the inner ear are mechanoreceptors. All sensory receptors initiate nerve signals.
Which type of receptors are found in the ear for hearing quizlet?
Hair cells are sensory receptors of inner ear for hearing, release neurotransmitter molecules to sensory neurons, covered on apical surface with long microvilli called stereocilia.
Where in the inner ear are receptors for hearing and maintaining balance located?
Deep inside the head is the inner ear, which contains 3 small, fluid-filled structures called the semicircular canals (ducts). Each duct has a swelling at the end called the ampulla. Within the ampulla are tiny "balance" receptors called crista.
Does organ of Corti contain auditory receptors?
The organ of Corti contains the auditory receptor cells (hair cells) and a system of supporting cells that hold them in place.
What is an auditory receptor?
A sensory receptor consisting of hair cells in the basilar membrane of the organ of Corti that translate sound waves—pressure waves with frequencies between 16 hertz and 20,000 hertz—into nerve impulses. Also called a phonoreceptor. From: auditory receptor in A Dictionary of Psychology »
What structure contains the receptors for the sense of hearing quizlet?
The structure in the vertebral inner ear that contains auditory receptors; also called organ of Corti. The saclike cavity of the inner ear that contains receptors for static equilibrium; sensitive to horizontal movements.
Where are the sensory receptors for sound?
The cochlea The cochlea has three layers called scala vestibuli (the ascending portion), scala media, and scala tympani (the descending portion). The organ of Corti is on the basilar membrane surface, and it contains hair cells which are the primary receptors in sound signal creation.
What does the cochlea contain?
The cochlea contains the sensory organ of hearing. It bears a striking resemblance to the shell of a snail and in fact takes its name from the Greek word for this object. The cochlea is a spiral tube that is coiled two and one-half turns around a hollow central pillar, the modiolus.
What is contained in the inner ear cavity?
Next to the middle ear in the bone of the skull is a small compartment which contains the hearing and balance apparatus known as the inner ear. The inner ear has two main parts. The cochlea , which is the hearing portion, and the semicircular canals is the balance portion.
What does the organ of Corti contain?
The Organ of Corti includes three rows of outer hair cells and one row of inner hair cells. Vibrations caused by sound waves bend the stereocilia on these hair cells via an electromechanical force.
Where is the auditory cortex located?
temporal lobe The primary auditory cortex (A1) is located on the superior temporal gyrus in the temporal lobe and receives point-to-point input from the ventral division of the medial geniculate complex; thus, it contains a precise tonotopic map.
What part of the ear is the cochlea?
the inner ear Next to the middle ear in the bone of the skull is a small compartment which contains the hearing and balance apparatus known as the inner ear. The inner ear has two main parts. The cochlea , which is the hearing portion, and the semicircular canals is the balance portion.
What is the cochlear duct?
The cochlear duct (also known as the scala media) is an endolymph-filled cavity located between the scala vestibuli (upper) and the scala tympani (lower) in the cochlea which is part of the inner ear along with the vestibular apparatus 1,4.
What is cochlea of ear?
The cochlea is a hollow, spiral-shaped bone found in the inner ear that plays a key role in the sense of hearing and participates in the process of auditory transduction. Sound waves are transduced into electrical impulses that the brain can interpret as individual frequencies of sound.
What is the organ of hearing?
The inner ear consists of a spiral shaped structure known as the cochlea (means snail-shell). Within the cochlea sits the organ of hearing where we have thousands of tiny cells, known as hair cells. The hair cells are stimulated and send messages to the auditory nerve.
What lobe is hearing for in the brain?
temporal lobe The temporal lobe contains the primary auditory cortex, which receives auditory information from the ears and secondary areas, and processes the information so we understand what we're hearing (e.g. words, laughing, a baby crying).
Where is the auditory cortex located quizlet?
~The primary auditory cortex is located in the temporal lobe.
What does the inner ear contain?
Next to the middle ear in the bone of the skull is a small compartment which contains the hearing and balance apparatus known as the inner ear. The inner ear has two main parts. The cochlea , which is the hearing portion, and the semicircular canals is the balance portion.
What ducts are in the ear?
The receptors for the organ of hearing are contained in the cochlear duct, while those for the organ of balance are contained in the utricle, saccule, and the three semicircular ducts. The cochlear duct (organ of hearing) communicates with the saccule (organ of balance) via the ductus reuniens.
Is the cochlea in the inner ear?
The inner ear has two main parts. The cochlea , which is the hearing portion, and the semicircular canals is the balance portion. The cochlea is shaped like a snail and is divided into two chambers by a membrane.
What is the cochlea?
The cochlea is a hollow, spiral-shaped bone found in the inner ear that plays a key role in the sense of hearing and participates in the process of auditory transduction. Sound waves are transduced into electrical impulses that the brain can interpret as individual frequencies of sound.
Where is the hearing center of the brain located?
The primary auditory cortex (A1) is located on the superior temporal gyrus in the temporal lobe and receives point-to-point input from the ventral division of the medial geniculate complex; thus, it contains a precise tonotopic map.
What is in frontal lobe?
The frontal lobes are important for voluntary movement, expressive language and for managing higher level executive functions. Executive functions refer to a collection of cognitive skills including the capacity to plan, organise, initiate, self-monitor and control one's responses in order to achieve a goal.
Which lobe of the cerebrum contains the auditory cortex quizlet?
The temporal lobe houses the primary auditory cortex and is primarily responsible for receiving and processing auditory information. The frontal lobe contains the primary motor cortex, which is responsible for controlling muscle movement.
What is the auditory cortex quizlet?
What is the Primary auditory cortex? It is that region of the temporal lobe which receives sound and is responsible for the ability to hear. It is an essential section of the cerebral cortex which accepts auditory data from medial geniculate body.
Is cochlea part of the middle ear?
The cochlea is the part of the inner ear involved in hearing. It is a spiral-shaped cavity in the bony labyrinth, in humans making 2.75 turns around its axis, the modiolus.
