Gracilis - Audio Lecture 0:00 / 0:00 1x 0.25x 0.5x 0.75x 1x 1.25x 1.5x 1.75x 2x The gracilis is a muscle of the medial compartment of the thigh. It is the most superficial and medial of the muscles in this compartment. Attachments: Originates from the inferior rami of the pubis and the body of the pubis. It descends down the medial aspect of the thigh and attaches to the medial surface of the tibial shaft. Actions: Adduction of the thigh at the hip and flexion of the leg at the knee. Innervation: Obturator nerve (L2-L4). Blood Supply: Medial circumflex femoral artery Adobe Stock, Licensed to TeachMeSeries Ltd Fig 1Gracilis muscle of the medial thigh Pro Feature - 3D Model You've Discovered a Pro Feature Access our 3D Model Library Explore, cut, dissect, annotate and manipulate our 3D models to visualise anatomy in a dynamic, interactive way.

Acknowledge Frequent questions What is the location of the gracilis muscle? The gracilis muscle is located in the medial compartment of the thigh, being the most superficial and medial muscle in this area. It runs along the inner thigh, connecting the pubis to the tibia. What are the attachments of the gracilis muscle? The gracilis originates from the inferior rami of the pubis and the body of the pubis, descending to attach on the medial surface of the tibial shaft. This positioning allows it to play a key role in leg movement. What actions does the gracilis muscle perform? The gracilis muscle is responsible for adducting the thigh at the hip and flexing the leg at the knee. These actions are essential for various movements, including walking and running. Which nerve innervates the gracilis muscle? The gracilis muscle is innervated by the obturator nerve, specifically from the L2 to L4 spinal segments. This nerve supply is crucial for the muscle's function and movement coordination. What is the blood supply for the gracilis muscle? The gracilis muscle receives its blood supply from the medial circumflex femoral artery. This vascularisation is important for maintaining muscle health and function. Rate This Article
