What is the function of each of these muscles?

stapedius:

sartorius:

gluteus maximus:
GPT-4o mini
Here are the functions of each of the muscles you mentioned:

1. **Stapedius**: The stapedius is a small muscle located in the middle ear. Its primary function is to stabilize the stapes bone (the stirrup), which is part of the auditory system. The stapedius helps dampen the intensity of sound vibrations to protect the inner ear from loud noises and contributes to the reflex that allows for the perception of sound.

2. **Sartorius**: The sartorius is the longest muscle in the human body, running from the outer side of the hip (anterior superior iliac spine) to the inner side of the knee (the medial aspect of the tibia). Its primary functions are to flex, abduct, and externally rotate the thigh at the hip joint, as well as to flex the knee. It is often associated with movements such as crossing your legs.

3. **Gluteus Maximus**: The gluteus maximus is one of the major muscles of the buttocks. Its primary functions are to extend, abduct, and externally rotate the hip joint. It plays a key role in activities such as walking, running, climbing stairs, and standing up from a sitting position. It is also important for maintaining an upright posture and stabilizing the pelvis during movement.

✔ supports bone in ear

sartorius:
✔ moves hip and knee

gluteus maximus:
