Document Summary
Msk3- body wall and back- lecture 16: our back supports our body weight. Flexors of spine innervated by the ventral rami nerve- will cause flexion (forward) of the spine. The muscles located on the anterior are more complex than the muscles in the posterior body wall: 4 muscles that make up the anterior body wall: 1. ) rectus abdominus: muscle that is in the front- muscle that is responsible for the flexion of the spine. Here is also where the 6 packs are formed when one works on their abdomen muscles. External oblique: they attach the rectus abdominus through a flat broad tendon and that is called aponeuroses. If you remove the superficial muscle and fascia we are able to see the segmented rectus abdominal muscle and the tendinous i(cid:374)te(cid:396)se(cid:272)tio(cid:374) (cid:271)et(cid:449)ee(cid:374) the(cid:373) a(cid:374)d (cid:449)e get the . Internal oblique muscle: it runs in the opposite direction- upwards medially- this creates the strongest amount material to support the abdominal, contents.
