Background: Combining neuroanatomical fiber information with other types of neuroimaging and genetic data can lead to a more comprehensive understanding of brain function and pathology. Variations in the branching patterns of the brachial plexus and the division of the sciatic nerve into the tibial and common fibular nerves has been documented in numerous studies, although not extensively in Ethiopia. The brachial plexus is formed by the ventral roots of spinal nerves from C5 to T1. Meanwhile, the sciatic nerve, which originates from the sacral plexus divides into the tibial and common fibular nerves at various points along its pathway. Given the significant implications of neural variations for enhancing medico legal practices, understanding these variations is crucial for making accurate diagnosis. Consequently, study examined different neuroantomical variants in Ethiopia. Objectives: To examine variations in the neural system connection and their clinical implications in the Ethiopian population and provide mechanistic insights into how different brain regions communicate and disruptions in these communications can lead to cognitive and behavioral symptoms. Methods and Materials: This research was carried out in a randomly selected medical institutions between January 2015 and February 2016. Preserved and carefully maintained human bodies were dissected by medical students, adhering to the protocols outlined in Grant’s Dissection Principles and Cunningham’s Manual of Practical Anatomy. The dissections took place in anatomy laboratory, with a specific focus on detecting any anatomical variations, particularly in the neural system of the human body. Results: In this study, we observed communication between the musculocutaneous nerve and the median nerve occurred in 6.3% of the sampled cases. Moreover, communication between the radial nerve and the ulnar nerve was found in 2.1% of the cases. Furthermore, variations in the pelvic division of the sciatic nerve were noted in 6.3% of the sampled cases from Ethiopia. Conclusion: We discovered a nerve responsible for communication within a specific part of the human body. Recognizing such communicating nerve fibers and their pathways is essential for clinicians to effectively diagnose sensorimotor symptoms. This understanding is also vital for neurologists, surgeons, and orthopedists in handling cases of nerve entrapment syndromes, carrying out post-traumatic assessments and undertaking exploratory procedures.
