  1. The external oblique muscle originates from the outer surface of the middle of the shaft of the lower six ribs as fleshy fibers. At its origin, the upper four slips and smaller four slips interdigitate with the serratus anterior and the latissimus dorsi muscles, respectively
  2. The external oblique muscle arises from the outer surface of the middle of the shaft of the lower six ribs as fleshy fibers. At its origin upper four slips and lower four slips interdigitate with the serratus anterior and the latissimus dorsi muscles respectively

The muscles of the anterior abdominal wall are flat muscles and include the rectus abdominis, the external and internal obliques, the transversus abdominis, and the pyramidalis. These muscles allow the trunk to bend either forward or laterally, maintain abdominal tone, and help increase intra-abdominal pressure We numbered aponeurosis of origin by arabic numerals and insertions by roman numerals (Hofling and Gasc, 1984). Possibly this occurred due to sharing aponeurosis of origin , which led Orenstein and Barlow (1981) to designate this muscle in a different manner Internal abdominal oblique is a muscle found on the lateral side of the abdomen.

Note that the muscle fibers of the external oblique do not extend all the way to the linea alba but are connected to it by an aponeurosis (a thin sheet of connective tissue). The internal oblique lies directly beneath the external oblique. Its fibers extend caudodorsally, nearly at right angles to the fibers of the external oblique Your Core Muscles are used to stabilise the pelvis during dynamic movement and stabilising and movement of the spine and pelvis. By stabilising the spine you are decreasing the risk of back injury. Major Muscle include: Transverse Abdominis; Rectus Abdominis; Internal and External Obliques The other end of the muscle stays fixed and the part of the muscle that moves is moved towards this fixed point. The fixed end of a muscle is called the origin of the muscle. Figure 8-3 illustrates muscle origins and insertions. Sometimes, the way muscles interact with other muscles are incorporated into their names This muscle was classified into four types based on the origin of its oblique head and was classified into three types based on the origin of its transverse head. The percent ratio of the weight of the oblique head to the total weight of all the intrinsic muscles of the foot was 9.4% +/- 1.5, and the transverse head was 1.5% +/- 0.6 (n = 14)
