It acts as the relay nuclei of the visceral primary
afferent fibers, which receive afferent information from the peripheral nerves and the spinal cord or medulla oblongata.
(1980) Distributions of vibrissae
afferent fiber collaterals in the trigeminal nuclei as revealed by intra-axonal injection of horseradish peroxidise.
Percutaneous denervation of the efferent sympathetic and sensory
afferent fibers of the renal nerves is a promising and safe therapeutic option but prospective randomized controlled trials are necessary to confirm that renal denervation will become vital in the treatment of resistant hypertension.
Functional analysis of group III
afferent fibers of mammalian muscles.
More specifically, the sympathetic nervous system could potentially serve as a bridge between injured
afferent fibers and sympathetic nerve fibers, (22) allowing abnormal afferent impulse to travel to efferent fibers and ultimately leading to continuous pain with involuntary movements.
A-delta fibers which are small diameter-myelinated and pain-transmitting fiber demonstrate the greatest decrease in conduction velocity in response to the cooling (29), but
afferent fibers that translate the proprioceptive information from muscle spindles to the CNS are type of I[alpha] and II meaning large myelinated fiber that have fast conduction (30).
The vagus is a mixed nerve, containing both efferent fibers (carrying nerve impulse to motor areas) and
afferent fibers (carrying nerve impulse back to the sensory areas--hence the term "affect").
The electrical stimulus activates the large sensory Ia
afferent fibers that travel to the spinal cord and synapse directly onto alpha-motoneurons.
Sprouting of primary
afferent fibers after spinal cord transection in the rat.
A prolonged somatic irritant, such as low back pain, that acts on
afferent fibers from the gastrointestinal tract might inhibit sensations of visceral pain and lead to bowel motility disorders.
The nerves are injured in irritable nociceptor pain, but some primary
afferent fibers are still intact.
