How do eye cells communicate with muscle cells?
The eye cells transmit nerve impulses to the brain, which translates the signal and transmits nerve impulses to the muscles. Information from sensory organs, including the eyes, ears, tongue, and skin, are transmitted by nerve impulses directly to the brain. The brain acting as the control center of the body interprets the nerve impulses. It then sends out different nerve impulses to other cells of the body if a response to the sensory signals is needed.
What is a mass of nerve tissue that receives and sends nerve impulses?
Neuron
Where does the spinal nerve take nerve impulses?
the spinal nerve sends nerve impulses away from the CNS
What sends impulses to the brain?
sensory neurons
Is the optic nerve a sensory or motor nerve?
The optic nerve is a cranial nerve (CN II) that sends special somatic afferent (sensory) fibers to the lateral geniculate of the thalamus. Here, they synapse and continue via optic radiations to the primary visual cortex of the brain. The motor portion of the eye is controlled by cranial nerves as well only they are: Oculomotor (CN III), Trochlear (CN IV), and Abducens (CN VI); there is also some sympathetic innervation (not from cranial nerves) that cause pupillary dialation.
What is the largest cranial nerve that receives sensory neurons from the face and sends motor neurons to the chewing muscles making it a mixed nerve?
Trigeminal. Sensory function- touch/temp/pain. Motor function-chewing. Branches-mandibular, maxillary and opthalmic.
Which parts of the brain receive the impulses from the auditory nerve?
The auditory nerve sends impulses to the brainstem's cochlear nuclei, which then project to the auditory cortex in the temporal lobe. This is where sound processing and interpretation primarily occur.
What is a difference between optic nerve and auditory nerve?
Optic nerve is found in the eye which sends the nerve impulses from the eye to the brain. The auditory nerve is present in the ear and sends the nerve impulses from the ear to the brain. They both have the same functions though they're present in different places.
Extension of a neuron that sends impulses to other nerve cells or to muscles or glands?
axon
What is the relay center for sensory impulses?
The thalamus is the main relay station for all sensory impulses going to the cortex of the brain, except olfactory sensations. Afferent nerve fibers come into the thalamus, which sends the signals on to the correct part of the cerebral cortex for processing. This is a large, oval structure located on either side of the third ventricle of the brain.
The brain sends and receives messages through 12 pairs if what?
The brain sends and receives messages through 12 pairs of cranial nerves. These nerves are responsible for various functions, including sensory perception, motor control, and autonomic functions. Each cranial nerve has specific roles, such as vision, hearing, taste, and facial movements, facilitating communication between the brain and different parts of the body.
Does A reflex arc begins with a receptor at the end of a sensory nerve?
No, a reflex arc begins with a receptor that detects a stimulus and sends a signal through a sensory nerve to the central nervous system.
