Oblique muscle of abdomen
The Oblique muscle of abdomen is a large, flat muscle group in the anatomical region of the abdomen. It is one of the most important muscles in the human body, playing a crucial role in various physical movements and functions.
Structure[edit]
The Oblique muscle of abdomen is divided into two parts: the external oblique muscle and the internal oblique muscle.
External oblique muscle[edit]
The external oblique muscle is the largest and the most superficial (outermost) of the three flat muscles in the lateral part of the abdomen.
Internal oblique muscle[edit]
The internal oblique muscle lies just beneath the external oblique muscle and is its direct antagonist.
Function[edit]
The Oblique muscle of abdomen is responsible for the twisting and turning movements of the trunk. It also helps in the lateral flexion of the trunk, aids in forceful expiration and supports the abdominal viscera against pull of gravity.
Clinical significance[edit]
Damage or strain to the oblique muscles can result in a variety of medical conditions, including abdominal hernias and lower back pain.
