What are the nerves that gather information from the environment and carry it to the CNS?
The sensory nerves gather information from the environment and carry it to the central nervous system. These nerves include the cranial nerves and spinal nerves, which transmit signals such as touch, pain, temperature, and pressure to the brain and spinal cord for processing.
What cranial nerve carries only motor information?
The cranial nerve that carries only motor information is the hypoglossal nerve, also known as cranial nerve XII. It is responsible for controlling the muscles of the tongue, which are essential for speech and swallowing. Unlike other cranial nerves, the hypoglossal nerve does not carry sensory information.
Which nerves innervate the taste buds?
Brances of the Facial (VII), Glossopharyngeal (IX), and Vagus (X) cranial nerves carry information about taste
What name refers to nerves that only originate in the brain carry messages to and from structures in the head and neck and are considered part of the peripheral nervous system?
Cranial nervesCranial Nerves only originate in the brain and carry messages to and from structures in the head and neck.
Which cranial nerves carries only sensory information?
The question is asking what three cranial nerves are purely sensory in their function. Some relevant terms here are olfactory, optic, and auditory or vestibucochlear or acoustic nerves. The only three cranial nerves that are pure sensory in function are cranial nerve #1 : the olfactory nerve (smell), cranial nerve #2 : the optic nerve (sight), and cranial nerve #8 : the auditory/vestibucochlear/acoustic nerve (hearing).
How do somatic sensory nerve impulses get to the brainstem from the head itself?
Somatic sensory nerve impulses from the head travel through the cranial nerves, such as the trigeminal nerve (V), facial nerve (VII), and glossopharyngeal nerve (IX). These nerves carry sensory information to the brainstem, specifically to the trigeminal nerve nuclei, which process and relay the information to higher brain regions for further processing and perception.
What nerves carry signals to and from the eyes and ears?
The oculomotor nerve or the third cranial nerve, trochlear or forth cranial nerve and abducent or the sixth cranial nerve carry signal to your eye. The optic nerve carry the signal from the eye to the brain. Vestibulocochlear or the eighth cranial nerve carry the signal from your ear to the brain.
What are the two nerves that carry the preganglionic axons to the parasympathetic ganglia?
The two nerves that carry preganglionic axons to the parasympathetic ganglia are the cranial nerves and the sacral spinal nerves. Specifically, cranial nerves III (oculomotor), VII (facial), IX (glossopharyngeal), and X (vagus) are involved. Additionally, the sacral spinal nerves S2 to S4 contribute to the pelvic splanchnic nerves, which also carry preganglionic parasympathetic fibers. These pathways play a crucial role in the parasympathetic division of the autonomic nervous system, facilitating various involuntary functions.
what consists the peripheral nervous system?
-cranial nerves: which are located on the brain and carry impulses to the head and neck -spinal nerves: which extend from the spine and provide information to areas of the body below the neck -autonomile nerves: which responsible for involuntary body functions such as breathing and digestion
What name refers to nerves that only originate in the brain carry messages to and from structures in the head and neck?
The nerves that originate in the brain and carry messages to and from structures in the head and neck are known as cranial nerves. There are 12 pairs of cranial nerves, each with specific functions related to sensory and motor control in the head and neck region. These nerves play crucial roles in activities such as vision, hearing, taste, and facial movements.
What two cranial nerves carry sensory information about blood pressure to the brain?
The glossopharyngeal nerve (CN IX) and the vagus nerve (CN X) carry sensory information about blood pressure from the carotid sinus and aortic arch to the brainstem.
What name refers to nerves that only originate in the brain carry messages to and from structures in the head and neck and are considered part of the peripheral nervous sytem?
These are 12 pairs of nerves called the cranial nerves.
