Auditory messages are conveyed to the brain via two types of pathway: the primary auditory pathway which exclusively carries messages from the cochlea, and the non-primary pathway (also called the reticular sensory pathway) which carries all types of sensory messages.The auditory pathway starts at the cochlear nucleus, then the superior olivary complex, then the inferior colliculus, and finally the medial geniculate nucleus. The information is decoded and integrated by each relay nucleus in the pathway and finally projected to the auditory cortex.STUDY. sound wave pathway. external auditory meatus–>tympanic membrane–>ossicles(found in middle ear malleus, incus, and stapes)–>inner ear vibrations from stapes–> hair cells of the cochlea–> left or right sprial ganglion–> through the vestibulocochlear nerve to left and right cochlear nuclei.

What is the auditory pathway to the brain?
The auditory pathway starts at the cochlear nucleus, then the superior olivary complex, then the inferior colliculus, and finally the medial geniculate nucleus. The information is decoded and integrated by each relay nucleus in the pathway and finally projected to the auditory cortex.

What is the auditory pathway quizlet?
STUDY. sound wave pathway. external auditory meatus–>tympanic membrane–>ossicles(found in middle ear malleus, incus, and stapes)–>inner ear vibrations from stapes–> hair cells of the cochlea–> left or right sprial ganglion–> through the vestibulocochlear nerve to left and right cochlear nuclei.
Where does auditory pathway begin?
[6] Auditory information ascending through the auditory pathways start at the auditory nerve. These nerves synapse within the cochlear nucleus. A majority of auditory information is then transmitted through crossing fibers into the superior olivary complex.
Where does the auditory pathway end?
The final neuron of the primary auditory pathway links the thalamus to the auditory cortex, where the message, already largely decoded during its passage through the previous neurons in the pathway, is recognized, memorized and perhaps integrated into a voluntary response.
What is the pathway of sound vibrations to the inner ear quizlet?
First, the sound waves enter the ear through the pinna, then to the auditory canal, then the eardrum. Then this causes vibrations through the tympanic membrane, making the mallus, incus, and stapes to vibrate forcefully.
What are the four steps for the pathway of sound waves quizlet?
- sound waves enter the outer ear and cause the tympanic membrane to vibrate.
- tympanic membrane vibrations are transferred by the inner ear bones.
- the stapes vibrates against the oval window.
- oval window creates “waves” which are carried through the Scala vestibuli by the perilymph.

Which parts of the auditory pathway receive input from both ears?
Thus, cells in the superior olive receive inputs from both ears and are the first place in the central auditory system where binaural processing (stereo hearing) is possible.
What is the correct pathway that sound waves travel from the external world to the inner ear quizlet?
Terms in this set (15) > Sound waves travel from the outer ear through the auditory canal, causing the eardrum (TM) to vibrate. > This causes the ossicles in the middle ear to move.
What is the purpose of the auditory system?
The auditory system transforms sound waves into distinct patterns of neural activity, which are then integrated with information from other sensory systems to guide behavior, including orienting movements to acoustical stimuli and intraspecies communication.
What are the functions of the descending auditory pathway?
In general, the descending pathway may be regarded as exercising an inhibitory function by means of a sort of negative feedback. It may also determine which ascending impulses are to be blocked and which are allowed to pass to other centres in the brain.
Which structure in the auditory pathway is found in the midbrain?
The inferior colliculus (IC) is a midbrain auditory structure that integrates information from several ascending auditory pathways, descending corticotectal projections, intercollicular pathways and extra-auditory sources, particularly from the somatosensory system.

How does sound travel through the ear quizlet?
The eardrum vibrates from the incoming sound waves and sends these vibrations the malleus, incus, and stapes. The ossicles increase the sound vibrations and send them to the cochlea in the inner ear. Once the vibrations cause the fluid inside the cochlea to ripple, a traveling wave forms along the basilar membrane.
What are the 3 functions of the external ear?
The external ear, which consists of the pinna, concha, and auditory meatus, gathers sound energy and focuses it on the eardrum, or tympanic membrane (Figure 13.3).
