It extends from the rib cage all the way to the pubic bone. Rectus abdominis belongs to the anterior abdominal muscles together with pyramidalis muscle.

Rectus abdominis muscle.
Origin | Pubic symphysis, pubic crest |
---|---|
Insertion | Xiphoid process, costal cartilages of ribs 5-7 |
Innervation | Intercostal nerves (T7-T11), subcostal nerve (T12) |
What bones are the abdominals attached to?
The Muscles:
Starting from the linea alba and working out, we first come to the rectus abdominis. [Shown in the image above with black vertical arrows. This is the left side of the body.] Starting from the pubic bone, these muscles connect with the fifth, sixth and seventh ribs and xiphoid process.
What bone is the rectus abdominis?
rectus abdominis – slung between the ribs and the pubic bone at the front of the pelvis. When contracting, this muscle has the characteristic bumps or bulges that are commonly called ‘the six pack’. The main function of the rectus abdominis is to move the body between the ribcage and the pelvis.
Where do the abdominal muscles attach?
The majority of the anterior abdominal wall is formed by the rectus abdominis muscle.
Origin and insertion.
Origin | Pubic crest, Pubic symphysis |
---|---|
Insertion | Linea alba |
Innervation | Subcostal nerve (T12) |
Blood supply | Inferior epigastric vessels |
Function | Tenses linea alba |
Where does rectus abdominis attach?

Origin | Crest of pubic |
Insertion | costal cartilages of ribs 5-7 Xiphoid process of sternum. |
Artery | inferior epigastric artery |
Nerve | segmentally by thoraco-abdominal nerves (T7 to T11) and subcostal (T12) |
Is the rectus abdominis anterior or posterior?
anterior
additional activation of the transverse abdominis muscle: linea alba is pulled posterior, while the rectus abdominis muscle becomes more pronounced at the anterior, suggesting the lateral slide of the posterior fascia with minimal lateral transfer of the rectus abdominis muscle.
What is rectus anatomy?
straight muscles
Definition of rectus
: any of several straight muscles (as of the abdomen)
What is Diastasis rectus abdominis?
Diastasis recti is a common condition in pregnant and postpartum people. It occurs when the rectus abdominis muscles (six-pack ab muscles) separate during pregnancy from being stretched. The separation can make a person’s belly stick out or bulge months or years postpartum.
Is diastasis recti permanent?
Will a diastasis recti go away on its own? Yes, sometimes. If you’ve had a baby within the past 6 to 12 months, be patient! It takes time for the body to readjust.
What is the difference between a hernia and diastasis recti?
A diastasis is the thinning and weakening of the connective tissue (linea alba) that connects the left and right sides of the rectus abdominis muscle (6-pack muscle). A hernia is the protrusion of an organ or piece of tissue from its normally contained space.
What does diastasis recti feel like?
A visible and palpable (detected by touch) separation of the rectus abdominis muscle. Feelings of “flabbiness” in the abdominal muscles. Pelvic-floor muscle dysfunction that causes urinary or bowel problems (incontinence, leakage, constipation, etc). Low back or pelvic or hip pain.
What happens if diastasis recti goes untreated?
If left untreated, diastasis recti can potentially lead to poor core stabilization, pelvic floor dysfunction, and back or pelvic pain.
What problems can diastasis recti cause?
Some of the most frequently occurring complications and signs of diastasis recti include:
- Belly pooch.
- Bloating.
- Lower back pain.
- Poor posture.
- Pelvic floor weakness.
- Stress urinary incontinence.
- Hernia.
- Lack of self-esteem.
