Adductor brevis
Musculus adductor brevis
- Latin synonym: Musculus adductor brevis
- Synonym: Adductor brevis muscle
Definition
Adductor brevis (Muscle group: Medial compartment of thigh) | |
Origin | Body and inferior ramus of pubic bone |
Insertion | pectineal line and upper one third of linea aspera of femur |
Artery | Obturator artery |
Innervation | Obturator nerve (L2, L3) |
Action | Adduction of hip, hip flexion and medial rotation of thigh. |
Origin
The adductor brevis is a short, triangular muscle of the medial compartment of the thigh, lying deep to the adductor longus and pectineus muscles, while superficial to the upper part of the adductor magnus muscle. Its muscle fibres originate from the external surface of the body of the pubis and adjoining part of the inferior ramus of the pubis.
Insertion
The adductor brevis inserts into the upper one-third of the linea aspera and the pectineal line on the posterior surface of the femur. Its insertion lies posterior to the pectineus and superior to the adductor longus.
Innervation
The adductor brevis lies in close relation to the obturator nerve, which supplies it. After the obturator nerve emerges from the obturator canal and enters the medial thigh, it typically divides into anterior and posterior branches .
The anterior branch passes anterior to the adductor brevis, running between the adductor longus and adductor brevis. In contrast, the posterior branch courses posterior to the adductor brevis, situated between the adductor brevis and adductor magnus. Together, these branches provide innervation to the adductor muscles of the medial thigh.
