The linea alba is a thin band of connective tissue running down the front of your abdomen, separating the left and right sides of the rectus abdominis.
Understanding the Linea Alba
Here's a more detailed look at this important structure:
- Location: The linea alba is located in the midline of the abdomen. According to provided reference, it begins at the lower end of your sternum (breastbone) and ends at the pubic bone.
- Composition: It's primarily made up of collagen fibers, a strong protein that provides structural support.
- Function: Its primary function is to serve as an attachment point for abdominal muscles.
- Relationship to the Rectus Abdominis: As noted in the reference, the linea alba separates the left and right sides of the rectus abdominis, often referred to as the "six-pack abs."
- Clinical Significance: The linea alba can be affected by conditions like diastasis recti, a separation of the rectus abdominis muscles, often seen after pregnancy.
