Sensory pathway lesions can be caused by a variety of factors, including traumatic injuries, tumors, stroke, and neurodegenerative diseases. Infections like multiple sclerosis or syphilis can also damage sensory pathways. Additionally, metabolic disorders, vascular issues, and exposure to toxins may lead to lesions in these pathways, disrupting normal sensory function. Overall, the specific cause often depends on the location and nature of the lesion within the nervous system.

If you accidentally step on a tack with your bare foot the pathway that the nerve impulse takes from your foot to your leg is called?
The pathway that the nerve impulse takes from your foot to your leg is called the sensory pathway. This pathway includes sensory neurons that carry signals from the foot to the spinal cord and then to the brain, where the sensation of pain is perceived and a motor response is initiated to move away from the tack.
How many directions can a nerve impulse travel in?
A nerve impulse can travel in two directions: towards the brain (sensory or afferent pathway) to convey sensory information, and away from the brain (motor or efferent pathway) to control muscle movement or glandular secretion.
What nerve acts as the afferent pathway in the pupillary reflex?
The optic nerve (cranial nerve II) carries sensory information about light intensity to the brain as part of the afferent pathway in the pupillary reflex.
What is the location of an interneuron in a spinal reflex pathway?
Interneurons are located in the spinal cord. They act as the middlemen in transmitting signals between sensory neurons (that detect stimuli) and motor neurons (that generate a response). In a spinal reflex pathway, after receiving sensory input from a sensory neuron, the interneuron processes the information before signaling the motor neuron to carry out a response.
What completes pathway between sensory neuron and motor neuron?
The pathway between a sensory neuron and a motor neuron is completed by an interneuron, also known as an association neuron. Interneurons relay signals between sensory and motor neurons, integrating and processing information before sending signals to initiate a response.
What are the four Parts of the Sensory Pathway?
Sensory pathways function to provide us with information about our environment. The four parts of the sensory pathway are receptors, sensory neurons, sensory tracts, and sensory areas of the brain.
Is the sensory receptor the first element in the sensory pathway?
Yes the sensory receptor is the first element.
Where is Cervical plexus in the sensory pathway?
lower back
What causes lesions on the scalp?
Poor hygiene?
What does not use a nonspecific ascending pathway to transmit sensory information to the brain?
Arousal.
Is pathway a sensory word?
No, "pathway" is not typically considered a sensory word since it primarily conveys a physical or metaphorical route or direction rather than appealing to the senses like taste, touch, sight, smell, or sound.
What is the stimulus-response pathway involving a sensory neuron and a motor neuron?

Is Synesthesia real?
Yes, synesthesia is a real neurological phenomenon where stimulation of one sensory pathway leads to automatic, involuntary experiences in a second sensory pathway. This can manifest as seeing colors when hearing music or tasting flavors when seeing numbers.
What is the ability to associate numbers and letters with certain colors?
Synesthesia This is a neurologically-based condition in which stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway. People who report such experiences are known as synesthetes.
How many directions can a nerve impulse travel in?
A nerve impulse can travel in two directions: towards the brain (sensory or afferent pathway) to convey sensory information, and away from the brain (motor or efferent pathway) to control muscle movement or glandular secretion.
Does Multiple Sclerosis causes lesions in the spinal cord?
yes
