Ascending nerve tracts are responsible for transmitting sensory information from the peripheral nervous system to the brain. They carry signals related to touch, pain, temperature, and proprioception, allowing the brain to process and interpret these sensations. Key ascending tracts include the spinothalamic tract, which conveys pain and temperature sensations, and the dorsal columns, which transmit fine touch and proprioceptive information. Ultimately, these tracts play a crucial role in our perception of the environment and bodily awareness.
What else can I help you with?
Is the efferent tract the major ascending tract?
No, the efferent tract is not the major ascending tract. The efferent tract is responsible for carrying nerve signals away from the central nervous system to muscles or glands, while ascending tracts carry sensory information from the peripheral nervous system to the brain.
What is descending tract and one ascending tract in upper motor neuron and lower motor neuron?
central nervous system (CNS) is the descending tract and one ascending tract in upper motor neuron and lower motor neuron.
What is another name for a bundle of neurons?
Rarley i have heard them be called "nervous cells" but nothing else
What cranial nerve tract is frequently misidentified as this nerve?
The cranial nerve tract frequently misidentified as the olfactory nerve (Cranial Nerve I) is the optic nerve (Cranial Nerve II). This confusion often arises because both nerves are involved in sensory functions related to the head and can be similarly affected by certain neurological conditions. However, they have distinct functions, with the olfactory nerve responsible for the sense of smell and the optic nerve for vision. Proper identification is crucial for accurate diagnosis and treatment in neurology.
Does the myenteric nerve plexus provides the major nerve supply to the GI tract wall and controls GI motility?
Yes, the large myenteric nerve plexus lies between the cirular and lomgitudinal muscle layers of the muscularis externa. Enteric neurons of this plexus provide the major nerve supply to the GI tract walls and controls GI tract motility. (page 778of Marieb, A&P 3rd edition)
Which of the following is not an ascending spinal cord nerve fiber tract?
reticulospinal
Is the efferent tract the major ascending tract?
No, the efferent tract is not the major ascending tract. The efferent tract is responsible for carrying nerve signals away from the central nervous system to muscles or glands, while ascending tracts carry sensory information from the peripheral nervous system to the brain.
what is the difference between ascending and descending tract?
An ascending tract goes upward. The descending tract goes downward.
What if the function of ascending colon?
The ascending colon carries fecal matter to transverse colon. Along it's tract, bacteria digest the fecal material to release vitamins, nutrients and water.
What is the ascending nerve tract?
Nerve are bi-directional (they travel in both direction) as they carry both snesory and motor neurones (which are uni-directional). However the white matter (the part that carries the impulses) in the spinal chord can be split in two. The anterior part (front part) carries the descenging, motor neurones. These are better termed the Efferent neurones which means they are travelling away from the central nervous system (CNS). The posterior part (or back part) carries the ascending, sensory neurones. These are better termed Afferent neurones which means they are travelling towards the CNS. In short the "ascending" nerve tract is the part of the spinal chord that carries sensory neurones.
What is descending tract and one ascending tract in upper motor neuron and lower motor neuron?
central nervous system (CNS) is the descending tract and one ascending tract in upper motor neuron and lower motor neuron.
What is the primary function of the ascending loop of henle?
the primary function of the ascending loop of henle in the kidney
What is the most important nerve of the digestive tract?
Vagus nerve
What is the longitudinal bundle of nerve fibers within the spinal cord constitute major nerve pathways called?
The longitudinal bundle of nerve fibers within the spinal cord that constitutes major nerve pathways is called the "white matter." It contains ascending and descending tracts that transmit sensory and motor information between the brain and the rest of the body. The major tracts include the corticospinal tract for motor control and the spinothalamic tract for pain and temperature sensation. These pathways are crucial for coordinating movement and processing sensory information.
What is the function of sacral nerve?
Autonomic nerve function in body
What is the function of median nerve?
what is the function of the median nerve
What is the function of the ascending aorta?
The ascending aorta delivers oxygenated blood FROM the heart, TO the head and arms.
