The Sacrococcygeal Joint [& Relevant Muscles, Neural Structures]

The video provides an in-depth look at the sacrococcygeal joint, its structure, function, and associated ligaments and discs. It explains the joint's movement, primarily in the sagittal plane, and its role during defecation and childbirth. The video also covers the nerve roots, their innervation roles, and the coccygeus muscle's function in supporting the pelvic floor. Additionally, it discusses the ganglion impar's role in pain management, particularly for conditions like vulvodynia and coccydynia.
