ABSTRACT

There is a lesser-known muscle located deep within the human body that has piqued the interest of medical professionals including anatomists due to its unusual characteristics although playing an important function in stability and movement. Located in the abdominal region, the psoas minor muscle is a thin band of tissue that is frequently left unnoticed due to its larger counterpart, the psoas major muscle. The psoas minor plays a significant role in the complex balance of the musculoskeletal system and thus has the ability to affect many facets of health and wellbeing. An additional split of the psoas minor muscle was noticed at the National Institute of Ayurveda in Jaipur during the routine dissection of the posterior abdominal wall of a 96-year-old cadaver of North Indian origin. The psoas minor muscle origin variation is the main subject of this study, which also focuses on the importance of an extra split origin of muscle.
