Dermatomes, Myotomes and DTR Poster

Shows the dermatome pattern of the cervical, thoracic, lumbar and sacral nerves. A dermatome is an area of skin that is mainly supplied by a single spinal nerve. There are eight cervical nerves (C1 being an exception with no dermatome), twelve thoracic nerves, five lumbar nerves and five sacral nerves. Each of these nerves relays sensation (including pain) from a particular region of skin to the brain.

Table of the upper and lower limb myotomes listed by spinal nerve level, action and muscles involved. A myotome is the group of muscles that a single spinal nerve root innervates.
Table of the deep tendon reflexes listed by tendon reflex, spinal level and normal response. Grading of the deep tendon reflexes (DTR) from grade 1 to 4.
