Diaphragm vs Gluteus maximus
| Property | Diaphragm | Gluteus maximus |
|---|---|---|
| Latin Name | Musculus diaphragma | Musculus gluteus maximus |
| Type | Muscle | Muscle |
| Body System | Muscular | Muscular |
| Body Region | Thorax | Hip |
| Function | The primary muscle of respiration. Contraction flattens the dome-shaped muscle, increasing thoracic volume and creating negative pressure to draw air into the lungs during inspiration. | The largest and most powerful muscle in the body. Primary extensor and lateral rotator of the hip. Essential for standing from a seated position, climbing stairs, running, and maintaining upright … |
| Clinical Significance | Diaphragmatic hernias allow abdominal organs to enter the thoracic cavity. Phrenic nerve paralysis causes diaphragmatic elevation. Hiccups result from involuntary diaphragmatic spasms. | Gluteus maximus weakness (Trendelenburg gait) results from inferior gluteal nerve injury. Gluteal muscle atrophy occurs with prolonged immobility. The muscle is used in myocutaneous flap surgery for pressure ulcer coverage. |
