Morphological variability of the pectoralis minor muscle. Study in human fetuses

CONCLUSIONS: Pectoralis minor is morphologically variable in the number of its bellies, its course, its origins, its insertions, and the location of its proximal attachments. The most common type (typical anatomy) was the type I represented by one belly. Other identified variants in the number of bellies by the present study may be hypothetically a result of prematurely terminated embryogenesis.PMID:38593907 | DOI:10.1016/j.aanat.2024.152264
