What is the dorsal column responsible for?
The dorsal column, also known as the dorsal column medial lemniscus pathway, deals with the conscious appreciation of fine touch, 2-point discrimination, conscious proprioception, and vibration sensations from the body; sparing the head.
What does dorsal column mean?
AKA posterior columns, the dorsal columns refers to the posterior spinal cord, which contains ascending sensory pathways that carry information about tactile sensations and proprioception.
Is the dorsal column motor or sensory?
sensory
The dorsal column–medial lemniscus pathway (DCML) (also known as the posterior column-medial lemniscus pathway, PCML) is a sensory pathway of the central nervous system that conveys sensations of fine touch, vibration, two-point discrimination, and proprioception (position) from the skin and joints.
What is dorsal column dysfunction?
Posterior cord syndrome is a rare type of incomplete spinal cord injury that affects the dorsal columns of the spinal cord (found in the posterior—or backside—region of the spinal cord), responsible for the perception of fine-touch, vibration, sense of self-movement, and body positioning (proprioception).
What sensation is detected by the dorsal column system?
The dorsal column-medial lemniscus pathway (DCML) is a sensory pathway of the central nervous system. It conveys sensation of fine touch, vibration, pressure, two-point discrimination and proprioception (position) from the skin and joints.
What are the columns of the spinal cord?
The gray matter mainly contains the cell bodies of neurons and glia and is divided into four main columns: dorsal horn, intermediate column, lateral horn and ventral horn column.
What happens when the dorsal root ganglia is damaged?
Damage to the dorsal root ganglion cells leads to simultaneous degeneration of short (non- length dependent) as well as long (length dependent) axons and it is this feature that is the key to understanding the clinical pre- sentation.
What happens if dorsal root of spinal nerve is damaged?
Spinal root avulsion injuries typically affect ventral and well as dorsal roots, causing paralysis of denervated muscles, loss of sensory and autonomic function, and, most often, neuropathic pain.
What would happen if the dorsal root of a spinal nerve is damaged?
What happens if the dorsal root of a spinal nerve is cut?
If the dorsal root of a spinal nerve is severed, output to skeletal muscles would be blocked. the spinal cord would not be able to process information at that level. output to visceral organs would be blocked.
What is dorsal and ventral root?
The dorsal root of spinal nerve (or posterior root of spinal nerve or sensory root) is one of two “roots” which emerge from the spinal cord. It emerges directly from the spinal cord, and travels to the dorsal root ganglion. Nerve fibres with the ventral root then combine to form a spinal nerve.
What are the dorsal root ganglia?
The dorsal root ganglia (DRG) are a collection of cell bodies of the afferent sensory fibers, which lie between adjacent vertebrae. From: Encyclopedia of Neuroscience, 2009.

What is the function of the dorsal column?
The dorsal column sustains an immense amount of connections with the peripheral nervous system. It relays information related to many different types of touch, motor functionality, and more.
What is the dorsal column-medial lemniscus pathway?
The dorsal column-medial lemniscus pathway (DCML) is a sensory pathway of the central nervous system. It conveys sensation of fine touch, vibration, pressure, two-point discrimination and proprioception (position) from the skin and joints. Also known as the posterior column – medial lemniscus pathway, it consists of two parts.
