Definition: Anapophysial is a term from Greek that refers to a ligament that connects the bladder with the sacrum or coccyx. It's often used in conjunction with the sacroiliac joint, which helps support the pelvis and prevents it from rotating too much while sitting or standing upright. The word is sometimes misinterpreted as "anapemic," referring to an inability to maintain a balanced pelvis; however, this term doesn't accurately describe the anatomy of the sacroiliac joint or its function in human physiology.
