该 transversus Abdominis, also known as the transversus muscle, is the deepest innermost layer of all abdominal muscle tissues and is located below your Rectus abdominis. The transversus Abdominis muscle runs horizontally across the abdomen and is recruited almost any time a limb actions.
The transversus Abdominis enables the breathing manner through supporting in exhalation and compressing the inner organs. 然而, its most important feature is to prompt the middle musculature and stabilize the pelvis and coffee back previous to movement of the frame. It acts as a natural “weight belt” or muscular girdle by means of resisting flexion of the lumbar spine (decrease back). The transversus maintains the cervical spine (颈部) in an impartial position at some point of core training and allows improving posture, muscle balance, and stabilization. A strong transversus Abdominis provides a solid foundation for any movement.
Transversus Abdominis muscle
The transversus Abdominis muscle, named consistent with the route of its muscle fibers, is one of the flat muscle tissues that shape the anterior belly wall. It’s miles deep to the inner indirect muscle and ends in the anterior aponeurosis, which ultimately blends with the Linea Alba. Right here are 3 transversus Abdominis muscle.
The transversus Abdominis is the private of the lateral stomach muscle mass (the others being the outdoor and internal indirect muscular tissues). It contributes mainly to keep belly tone and might boom intra-stomach strain when it contracts.
It attaches to the lateral -thirds of the inguinal ligament and the related iliac fascia, the inner lip of the anterior phase of the iliac crest, the thoracolumbar fascia between the iliac crest and the twelfth rib, and the costal cartilages of ribs 7-12. It ends in the anterior aponeurosis, with most people of its fibers blending into the Linea Alba.
As a flat muscle, the vascular delivery of the transversus Abdominis consists of the posterior intercostals and subcostal arteries, superior and inferior epigastric arteries, superficial and deep circumflex arteries and posterior lumbar arteries.
It’s far innervated by way of the terminal branches of intercostals nerves t7-t12, the subcostal nerve, the iliohypogastric nerve and ilioinguinal nerves. These nerves upward thrust up from the ventral rami of the spinal nerves of t7-tl1, and that is the simplified description of Innervation defined in anatomy textbooks.
