Muscle
Adductor brevis
Short adductor between two nerve divisions
High-yield
The obturator nerve's anterior division runs in front of brevis and its posterior division behind it. Brevis usually receives the anterior branch, but posterior contributions are documented.
Overview
This muscle links the pubis to the upper posterior femur. Pectineus and adductor longus cover it from the front, while its position helps identify the branches of the obturator nerve in the medial thigh.
Reference facts
- Origin
- Anterior pubic body and adjoining inferior ramus
- Insertion
- Pectineal line and upper portion of the femoral linea aspera
- Action
- Draws the thigh toward the midline and contributes to hip flexion
- Innervation
- Obturator nerve, usually its anterior division; commonly mapped within L2-L4, with L2-L3 emphasized in some references
- Blood supply
- Branches of the profunda femoris and obturator arterial systems
