ventral root การใช้

• They exit through the ventral root of the spinal cord, and continue through the ventral rami.
• The spinal motor neurons project out of the cord to the correct muscles via the ventral root.
• Here they arise from the thoracolumbar ( T1-L2 ) regions'lateral horn of grey and emerge via the ventral root.
• The median nerve originates from the lateral and medial cords of the brachial plexus, and has contributions from ventral roots of T1 ( medial cord ).
• "Therefore, we examined the contribution of selected levels of the neuraxis in mediating the pressor reflex evoked by muscular contraction from stimulation of ventral roots.
• The cord is stabilized within the dura mater by the connecting denticulate ligaments, which extend from the enveloping pia mater laterally between the dorsal and ventral roots.
• In the same year, Charles Bell finished work on what would later become known as the Bell-Magendie law, which compared functional differences between dorsal and ventral roots of the spinal cord.
• Ventral roots only have efferent fibers that arise from motor neurons ( general somatic efferent neurons ) whose cell bodies are found in the ventral ( or anterior ) gray horns of the spinal cord.
• Ventral roots consist of axons from motor neurons, which bring information to the periphery from cell bodies within the CNS . Dorsal roots and ventral roots come together and exit the intervertebral foramina as they become spinal nerves.
• Ventral roots consist of axons from motor neurons, which bring information to the periphery from cell bodies within the CNS . Dorsal roots and ventral roots come together and exit the intervertebral foramina as they become spinal nerves.
• Direct infiltration of the nerve roots is also observed, mostly from the dorsal roots ( the afferent sensory root of the spinal nerve ) than the ventral roots ( the efferent motor root of a spinal nerve ).
• Peripheral sensory cell > Preganglionic cell > Dorsal root ganglia cell in the " Sympathetic chain " > Ventral root ganglia cell in the " sympathetic chain " > Post-ganglionic cell that activates an organ such as the pancreas ( or a muscle ).
• Slightly myelinated preganglionic fibers ( aka visceral efferent fibers ) leave the lateral grey column through the ventral roots and promptly form fourteen aggregates called white rami communicantes, also known as white communicating rami, which eventually enter the sympathetic trunk, a structure next to the vertebral column that consists of paired chains of sympathetic ganglia connected by nerve fibers.
