The anterior principal rami of C5 to C8 and
T1 are joined to form brachial plexus (Bp), a network of
nerves that wraps around neck and axilla of the body.
Trauma, radiation, neoplasms, infections, and
autoimmune diseases can all have an impact on Bp. The
technical expertise required for clinical and surgical
procedures is described in existing publications.
Beginners still find it particularly difficult to use its many
elements while navigating. The objective was to identify
the differences in the demographic characteristics (male
and female) of Bp among the population. A descriptive,
cross-sectional study was carried at Maseno, Masinde
Muliro, and Uzima Universities' anatomical laboratory
departments. Total of 70 (35 males and 35 females)
cadavers sample size was used from 86 cadavers using
Yamane Taro formula. Ethical consideration was
observed. Data analysis was done using SPSS vs26. X2
was used. Significance was set at a P–value = 0.05. Study
comprised of 140 Bp (left and right sides). In the study
population, Bp varied by gender, with median nerve
accounting for a larger proportion. There was a
statistically significant difference (p=0.008) in the
variation of median nerve distribution in relation to the
sexes. Variations noted were significant in the formation
of roots, trunks, divisions, cords, and terminal branches.
Coexistence of these differences is essential for it enables
surgeons and anesthesiologists avoid purposeful damage
to Bp nerves. Understanding these variances is crucial
when evaluating sensory and motor loss that has been
explained following surgery or trauma to upper limb.
