What are tendinous intersections made of?
What are tendinous intersections made of?
Anatomy Def: Tendinous intersections are fibrous bands crossing the rectus abdominis muscles and marked by overlying skin grooves (curved red arrow).
Why does the rectus abdominis have Tendinous inscriptions?
The tendinous inscriptions limit fluid collection beneath the anterior rectus sheath, prevent muscle rupture, and aid in the biomechanics of the RA [1-2].
Which of the following muscles contains tendinous intersections?
The rectus abdominis muscle is crossed by three horizontal fibrous bands called the tendinous intersections. Typically they are found at the level of the umbilicus, the inferior tip of the xiphoid process, and halfway between these two points.
What muscles does the tendinous sheath of the abdomen extend out of?
It is an extension of the tendons of the external abdominal oblique, internal abdominal oblique, and transversus abdominis muscles.

What does Aponeurotic mean?
ap·o·neu·ro·sis (ăp′ə-no͝o-rō′sĭs, -nyo͝o-) pl. ap·o·neu·ro·ses (-sēz′) A sheetlike fibrous membrane, resembling a flattened tendon, that serves as a fascia to bind muscles together or as a means of connecting muscle to bone.
What is aponeurosis and its function?
An aponeurosis is a type of connective tissue found throughout the body. Aponeuroses provide an attachment point for muscles to connect to bone, and can also envelope muscles and organs, bind muscles together, and bind muscles to other tissues. They are important for muscle movement and posture.
What is the function of the tendinous intersections?
The tendinous intersections define the anatomy of the rectus abdominis and assist with physiological movement. If the rectus abdominis did not have tendinous intersections, there would be one large muscle group on each side of the linea alba.
What are tendinous intersections of the rectus abdominis?
tendinous intersections of rectus abdominis. [TA] usually three but occasionally four transverse fibrous bands or partial bands occurring at intervals as interruptions of the fleshy, contractile portions of the rectus abdominis muscle; they usually occur at and superior to the umbilicus.
What are tendinous inscriptions in anatomy?
Anatomical terminology. The rectus abdominis muscle is crossed by three fibrous bands called the tendinous intersections or tendinous inscriptions. One is usually situated at the level of the umbilicus, one at the extremity of the xiphoid process, and the third about midway between the two.
What are the intersections of the muscle?
These intersections pass transversely or obliquely across the muscle; they rarely extend completely through its substance and may pass only halfway across it; they are intimately adherent in front to the sheath of the muscle. Sometimes one or two additional intersections, generally incomplete, are present below the umbilicus.
