Oct 30, 2023 · Coccygeus is a sheet of muscle and fibrous tissue of the pelvis. Together with levator ani, it comprises the pelvic diaphragm that forms the inferior wall of the true pelvis.

Coccygeus also known as ischiococcygeus is a triangular-shaped sheet of muscle located posterior to the levator ani muscles in the pelvic floor. The coccygeus, together with the levator ani, forms the pelvic diaphragm.

The coccygeus muscle or ischiococcygeus is a muscle of the pelvic floor located posterior to levator ani and anterior to the sacrospinous ligament.

Aug 12, 2017 · The coccygeus and levator ani are pelvic floor muscles located between the sacrum and coccyx medially and the pelvic bone laterally (Figure 11). As pelvic floor muscles, they are important toward maintaining the stability of the abdominopelvic cavity, and therefore the core of the body.

The coccygeus (ischiococcygeus) muscle is one of the muscles of the pelvic diaphragm. It is a flat, triangular skeletal muscle that forms the posterosuperior part of the pelvic diaphragm.

Sep 12, 2024 · The coccygeus muscle, also known as the ischiococcygeus, is one of the muscles that make up the pelvic floor. Located deep within the pelvis, this muscle runs from the ischial spine, a bony projection of the pelvis, to the coccyx (the tailbone).

Mar 27, 2025 · The coccygeus muscle, also known as the ischiococcygeus muscle, is a remnant muscle of the pelvic floor. The coccygeus is a paired muscle which is triangular in shape and overlies the sacrospinous ligament.

coccygeus muscle, muscle of the lower back that arises from the ischium (lower, rear portion of the hipbone) and from the ligaments that join the spinal column and the sacrum (triangular bone at the base of the spine). It is attached to the lower sacrum and the coccyx (tailbone).

Jan 19, 2023 · The coccygeus is a muscle of the pelvic floor. It is a small triangular muscle located posterior to the levator ani muscle group. Attachments: Originates from the ischial spines and inserts onto the inferior end of the sacrum and coccyx. Actions: Supports the pelvic viscera and flexes the coccyx. Innervation: Anterior rami of S4 and S5.

The Coccygeus Muscle is defined as a paired muscle that runs from the lateral borders of the coccyx and sacrum to the ischial spines on each side. It is part of the levator ani muscle group that forms the pelvic diaphragm.
