While motor endplates are the primary site of action for BoNT, their location is unknown in most human muscles. This study localized the motor endplate bands (MEB) within human biceps brachii (BB) muscles in relation to external landmarks.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Five human BB muscles were obtained from autopsy.

The ratio of MEB location to total olecranon-acromion length is 0.25 at the lateral edge, 0.39 in the midline, and 0.28 at the medial edge.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>This study localized MEB in human BB in reference to external landmarks.
