Frequency and characterization of the accessory heads of the biceps brachii: A multicentric cadaveric study
Purpose
The biceps brachii muscle (BBM) is a large and thick muscle on the ventral portion of the upper arm. The scientific literature reports the existence of extra heads.
Objective
The present work investigated the frequency of occurrence of BBM accessory head(s) in four different Anatomy Laboratories at universities in Northeast Brazil.
Material and methods
Once the upper limbs with an anatomical variation of the BBM heads were identified, the accessory head was evaluated for morphometric characterization (the length, width, and thickness).
Results
The sample consisted of 249 upper limbs and the outcomes were 26 members with BBM accessory heads (10.44% of the total sample). Among the 26 members studied was found a single accessory head in 22 (84.62%), two accessory heads in 3 (11.54%), and three accessory heads in 1 (3.85%). BBMs with one, two, and three accessory heads were found, with different origins. The average length, width, and thickness of these accessory heads were 169.39 mm, 10.25 mm, and 3.39 mm, respectively.
Conclusion
The frequency of BBM accessory heads in a population of northeastern Brazil in this cadaveric study was 10.44%.
期刊介绍：
Morphologie est une revue universitaire avec une ouverture médicale qui sa adresse aux enseignants, aux étudiants, aux chercheurs et aux cliniciens en anatomie et en morphologie. Vous y trouverez les développements les plus actuels de votre spécialité, en France comme a international. Le objectif de Morphologie est d?offrir des lectures privilégiées sous forme de revues générales, d?articles originaux, de mises au point didactiques et de revues de la littérature, qui permettront notamment aux enseignants de optimiser leurs cours et aux spécialistes d?enrichir leurs connaissances.
