Dermatomes

The video tutorial by Dr. Morton explores the sensory deficits that occur when injuring a brachial plexus root compared to a peripheral nerve. It explains the concept of dermatomes, areas of skin supplied by sensory neurons from a single spinal cord level, and how these neurons are transmitted through various nerves. Using an analogy with Google Maps, the tutorial illustrates how understanding the brachial plexus is akin to mapping routes. It includes practice questions to reinforce learning about dermatomes, cutaneous fields, and nerve injuries, emphasizing the impact of injuries on sensation.
