Sensory Spinal Pathways

SSEP monitoring is utilised for the protection of the patients ascending sensory spinal pathways (dorsal column). If the dorsal column is affected, then on or all of these functions may be affected.

• Proprioception (or kinesthesia) is the sense though which we perceive the position and movement of our body.
• Including our sense of equilibrium and balance, senses that depend on the notion of force

• The ability to know the shape of an object without looking at it
• Involves the signal being sent through the joint and receptors

Proprioception

5 Sensory Functions

Tactile Discrimination

Vibration Sensation

• Also known as Pallesthesia, is the ability to perceive vibration.
• Usually generated by mechanoreceptors such as Pacinian corpuscles, Merkel disk receptors, and tactile corpuscles.

• The ability to differentiate information through the sense of touch
• two point discrimination happens as the sensory function is transmitted to the deramtome (patch of the skin which goes to the brain), if 2 separate dermatomes are stimulated they are experienced as two sensations

Weight Discrimination

• being able to tell the weight of an object when held without looking at it
