Dermatomes Of The Upper Limb Part 1 2 By Dr A K S The term “dermatome” is a combination of two ancient greek words; “derma” meaning “ skin ”, and “tome”, meaning “cutting” or “thin segment”. it is an area of skin which is innervated by the posterior (dorsal) root of a single spinal nerve. as posterior roots are organized in segments, dermatomes are as well. The lists below describe locations that can be used to assess the dermatomes of the head, upper limb, torso and lower limbs. 1 we have also included a selection of dermatomal maps to demonstrate the region of the skin each dermatome covers. dermatomes of the head trigeminal nerve (cn v) v1: ophthalmic branch – the lateral aspect of the forehead. Dermatomes divide the skin according to sensory nerve distribution (see image. dermatome map). one of the first to map out and discuss the dermatomes is o. foerster in his 1933 publication entitled “the dermatomes in man” in the journal brain. some consider his work the foundation of dermatomal theory.[1] in 1948, j. keegan and f. garrett described spinal nerve distribution in the. Dermatomes vary based on the method of assessment, the type of sensation tested, and the precise neural element being tested. lee et al's map is the most consistent for tactile dermatomal regions for each spinal dorsal nerve root. the midline has minimal overlap, but otherwise there is extensive and variable overlap.

The nerve supply to the upper limb is almost entirely supplied by the brachial plexus , a complex intercommunicating network of nerves formed in the neck by spinal nerve roots c5, c6, c7, c8 and t1. the brachial plexus itself in more detail in a separate article here. figure 1 summarises the structure and branches of the brachial plexus. Dermatomes. a 40 year old man presents to his primary care physician with bilateral upper extremity weakness and sensory changes. he describes the sensory changes as "numb to pain and heat." approximately 8 months ago, he had a multiple sclerosis exacerbation that required hospitalization with intravenous methylprednisolone for 5 days.
