musclesrectus

Musclesrectus is a term that appears to be a misspelling or a non-standard anatomical designation. In human anatomy, the prefix "rectus" refers to muscles that are straight. The most commonly known rectus muscles are the rectus abdominis, a prominent muscle of the abdomen, and the rectus femoris, a large muscle in the thigh. The rectus abdominis is responsible for flexing the trunk and maintaining posture. The rectus femoris is part of the quadriceps group and plays a key role in extending the knee and flexing the hip.

Other rectus muscles exist in the eye, such as the superior rectus, inferior rectus, medial rectus, and lateral rectus. These extraocular muscles control the movement of the eyeball. Without further context or clarification, "musclesrectus" does not correspond to a recognized anatomical term. It is possible it refers to a collection of rectus muscles or a specific muscle not commonly referred to by this exact phrasing. If "musclesrectus" is intended to refer to a specific muscle or group of muscles, providing additional details would be necessary for accurate identification and description. The use of "rectus" in muscle names consistently indicates a straight orientation of the muscle fibers.
