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.
Can a nerve fibre and nerve both carry sensory and motor impulses?
There are the Mixed Nerves in the spinal column that carry both sensory and motor nerves, but these neurons have 2 different jobs that they do,& I know of no neurons doing both as the impulses travel to 2 different locations which couldn't be done at the same time.
What nerves carry impulses to the brain and spinal cord?
remember the word SAMESensory are AfferentMotor are Efferent
What is the difference between sensory nerve and motor nerves?
Sensory nerves carry impulses to the brain (as sights seen, sounds heard, etc.). Motor nerves carry impulses from the brain to cause the body to do things such as move muscles.
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.
Nerves that carry impulses toward the Central Nervous system only are?
Sensory neurons are nerves that carry electrical signals only toward the Central Nervous System. These nerves are found in the ganglia.
Where do sensory nerves in a reflex action carry impulses?
In a reflex action, sensory nerves carry impulses from sensory receptors in the body to the spinal cord. Upon reaching the spinal cord, these impulses are relayed to motor neurons, which then transmit signals to the muscles, eliciting a quick, involuntary response. This pathway allows for rapid reactions without involving the brain, enabling immediate responses to stimuli.
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).
What nerve carries impulses through the spinal cord?
The spinal cord and the abdomen, limbs, and chest. Spinal nerves carry impulses between the spinal cord and the abdomen, limbs, and chest. Cranial nerves carry impulses between the brain and the neck and head.
What are sensory nerves?
Sensory nerves are part of the peripheral nervous system which includes the cranial and spinal nerves. They bring impulses to the central nervous system which includes the brain and spinal cord. Peripheral means the sides and that is why the sensory nerves are referred to as the peripheral nervous system. All of the nervous system is related to the skin because both the nervous system tissues and skin tissues originated in endoderm during the gastrula stage of embryonic development. The sensory nerves form the link between receptors and the central nervous system (CNS). They carry nerve impulses from stimulated receptors to the CNS. They are also referred to as afferent nerves.
Similarities of motor and sensory neurons?
Sensory neurones carry impulses to the CNS, motor neurones carry impulses to muscles.
What type of nerve sends messages from sense organs to the brain?
Sensory nerves, also known as afferent nerves, transmit messages from sense organs to the brain. These nerves are responsible for carrying information about sensations such as touch, temperature, pain, and proprioception to the central nervous system for processing.
