- Auditory System Anatomy - Neurophysiologic Considerations. 1  The complex chain of nerve cells in the auditory system helps to process and relay auditory information, encoded in the form of nerve impulses, directly to the highest cerebral levels in the cortex of the brain. To some extent, different properties of the auditory stimulus are conveyed along distinct parallel pathways.

wrist ganglion The ganglion contains the cell bodies of bipolar neurons that receive equillibrium information from the membranous labyrinth of the semicircular canals in the inner ear. The axons of these neurons form the vestibular component of the vestibulocochlear nerve and synapse in the vestibular nuclei in the brainstem.

How Do Nerve Impulses From the Retina Reach the Brain? The optic nerve, which is a collection of retinal nerve fibers, conducts the electrical impulses to the optic chasm of the brain, according to the Vision for Tomorrow Foundation. Half of the retinal nerve fibers from each retina's inner half cross to the other side of the brain. The nerve fibers meet at the occipital lobe in the back of the brain. Vision is interpreted by the brain in the primary visual cortex. Each rod and cone, which are photoreceptors, in the retina is connected to the optic nerve by a tiny nerve branch, according to the Merck Manual Home Edition.

- Quick Answer. The cochlea is the auditory center of the inner ear, a fluid-filled organ that translates the vibrations of auditory sound into impulses the brain can understand. This occurs at the organ of Corti, a structure consisting of tiny hairs throughout the cochlea that vibrate and send electrical signals through the nervous system. Continue Reading

- As the stapes moves, it pushes a structure called the oval window in and out. This action is passed onto the cochlea, which is a fluid-filled snail-like structure that contains the receptor organ for hearing. The cochlea contains the spiral organ of Corti, which is the receptor organ for hearing. It consists of tiny hair cells that translate the fluid vibration of sounds from its surrounding ducts into electrical impulses that are carried to the brain by sensory nerves.

- Visceral afferent neurons are unipolar neurons that enter the spinal cord through the dorsal root & their cell bodies are located in the dorsal root ganglia. Visceral efferent neurons are motor neurons that conduct impulses to smooth muscle, cardiac muscle, & glands. These neurons make up the Autonomic Nervous System. Some visceral efferent neurons begin in the brain; others in the spinal cord.

The Autonomic Nervous System From these centers efferent impulses are conveyed to all parts of the body by the parasympathetic and sympathetic nerves. The impulses of the parasympathetic system reach the organs of the body through the cranial nerves # 3, 7, 9, & 10, and some sacral nerves to the eyes, the gastrointestinal system, and other organs.

Neuron A sensory neuron transmits impulses from a receptor, such as those in the eye or ear, to a more central location in the nervous system, such as the spinal cord or brain. A motor neuron transmits impulses from a central area of the nervous system to an effector, such as a muscle.

Auditory Nerve The Auditory Nerve, also known as the Cochlear or acoustic nerve (part of the vestibulocochlear or 8th cranial nerve), is a sensory nerve, it is found in the head and transmits information from the inner ear (cochlea) to the brain in the form of sound (acoustic) energy that impinges on the ear drum (tympanic membrane).he Auditory Nerve, also known as the Cochlear or acoustic nerve (part of the vestibulocochlear or 8th cranial nerve), is a sensory nerve, it is found in the head and transmits information from the inner ear (cochlea) to the brain in the form of sound (acoustic) energy that impinges on the ear drum (tympanic membrane).

- These roots become nerves that innervate (transmit nerve impulses to) muscles and organs throughout the body. Twelve pairs of cranial nerves transmit from special sensory receptors information on the senses of balance, smell, sight, taste, and hearing.he thalamus is a relay and preprocessing station for the many nerve impulses that pass through it. Impulses carrying similar messages are grouped in the thalamus, then relayed to the appropriate brain areas. The epithalamus is the most dorsal (posterior) portion of the diencephalon.

nerve The retina converts the image formed by the light rays into nerve impulses. The optic nerve, composed of the axons of the , then transmits these impulses from the eye to the first visual relay in the brain. The axons of the collect in a bundle at the and emerge from the back of of the eye to form the optic nerve. The optic nerve is the pathway that carries the nerve impulses from each eye to the various structures in the brain that analyze these visual signals.

Auditory Brain Auditory brain centres. Auditory nerve fibres transmit the signals sent from the cochlea to the brain. In the brain, numerous relay stations (groups of neurones) receive the signals and decode them (soft or loud sound, high or low, its location etc.) in order to cause a sensation or conscious perception.

What Are the Neurons That Carry Impulses Toward the Spinal Cord and Brain? Sensory neurons receive impulses and carry messages from the sense organs to the brain. Once the brain receives this information, it sends new information to the motor nerves to tell them what actions to perform.

- Sound In The Brain. The ear sends impulses to the brain through the auditory nerve to the ventral cochlear nucleus. Most of these signals are projected to a structure called the superior olivary complex, which is involved in determining the location of sounds.
