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 else can I help you with?
What are the nonspecific ascending pathways?
The nonspecific ascending pathways are neural pathways that carry sensory information related to pain, temperature, and crude touch. These pathways are not as precise in their localization of sensory input compared to specific ascending pathways. Examples include the spinothalamic tract and spinoreticular tract.
What is a group of axons bundled together coated in myelin that travels together through the body called?
A group of axons bundled together and coated in myelin that travel together through the body is known as a nerve fiber or a nerve tract. These nerve fibers facilitate the transmission of electrical impulses from one part of the body to another.
Which layer of the digestive tract contains blood and lymph vessels and nerve cells?
The submucosa layer of the digestive tract contains blood vessels, lymph vessels, and nerve cells. These structures play important roles in providing nutrients, removing waste, and coordinating digestive functions within the gastrointestinal tract.
How is the light optic tract anatomically different from the right optic nerve?
The right optic tract carries information from the left hand side of both eyes visual field, where-as the right optic nerve carries information solely from the right had eye. After the optic nerves from both eyes perform this partial intersection (in the optic chiasm) they then become known as the optic tract. Hope this helps.
What is the bundle of nerve fibers that send messages to the brain which interprets them?
The bundle of nerve fibers that send messages to the brain for interpretation is called the sensory pathway. These pathways carry sensory information from the peripheral nervous system to the brain where it is processed and interpreted.
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 is a function of ascending nerve tract?
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 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 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 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.
A group of nerve fibers in the central nervous system?
A Tract
What is a bundle of nerve processes inside the CNS?
The usual name for a bundle of nerve processes within the CNS is "tract" or "fasciculus"
What are the nonspecific ascending pathways?
The nonspecific ascending pathways are neural pathways that carry sensory information related to pain, temperature, and crude touch. These pathways are not as precise in their localization of sensory input compared to specific ascending pathways. Examples include the spinothalamic tract and spinoreticular tract.
What cranial nerve is involved in the movement of the digestive tract?
The cranial nerve primarily involved in the movement of the digestive tract is the vagus nerve, or cranial nerve X. It plays a crucial role in the autonomic regulation of the digestive system by controlling the muscles of the gastrointestinal tract, promoting peristalsis, and stimulating digestive secretions. The vagus nerve also helps regulate heart rate and other involuntary functions, linking the brain to the digestive organs.
