The cochlear nerve, also known as the acoustic nerve , is the sensory nerve that transfers auditory information from the cochlea (auditory area of the inner ear) to the brain. It is one of the many pieces that make up the auditory system, which enables effective hearing.
Which nerve carry information from the ear to the brain?
Coming from the inner ear and running to the brain is the eighth cranial nerve, the auditory nerve . This nerve carries both balance and hearing information to the brain. Along with the eighth cranial nerve runs the seventh cranial nerve.
What nerves carry messages to the brain?
We have three types of nerves: motor nerves that carry messages from brain or spinal cord to motor organs only, sensory nerves that carry messages from sensory organs to spinal cord or brain only and mixed nerves that carry messages to and from both sides.
What part of the body sends messages from your ears to your brain?
Our hearing system has many working parts. The outer ear collects the sounds which vibrate the eardrum in the middle ear. The inner ear gets these vibrations and sends them to the auditory nerve. These impulses go to our brain, which translates them into what we hear.
Is auditory a nerve?
The cochlear nerve, also known as the acoustic nerve, is the sensory nerve that transfers auditory information from the cochlea (auditory area of the inner ear) to the brain. It is one of the many pieces that make up the auditory system, which enables effective hearing.
What can you do for inner ear fluid?
Typically, treatment is not necessary for fluid in the ears. 2 The fluid will usually drain on its own within a few weeks. However, if it does not, treatment will depend on several factors. If the fluid is present for 6 weeks, treatment may include a hearing test , a round of antibiotics, or further observation.
Does blood travel through nerves?
In terms of function, blood flow is unidirectional, arterial to venous, just as information passes along incoming (sensory) and outgoing (motor and autonomic) nerve pathways.
Who controls reflex?
The spinal cord is the primary control centre for reflex behaviour. The spinal cord connects the brain and the spinal nerves. So we can say that, reflex arc is controlled by the spinal cord.
Which branch of a nerve carries a message to the brain from a muscle?
Motor neurons have a long axon and short dendrites and transmit messages from the central nervous system to the muscles (or to glands).
Which organ is part of our nervous system?
