A symphysis (/ ˈ s ɪ m. f ɪ. s ɪ s /, pl.: symphyses [1]) is a fibrocartilaginous fusion between two bones. It is a type of cartilaginous joint, specifically a secondary cartilaginous joint. A symphysis is an amphiarthrosis, a slightly movable joint. A growing together of parts or structures. Unlike synchondroses, symphyses are permanent. [2]
The pubic symphysis is a nonsynovial amphiarthrodial joint. The width of the pubic symphysis at the front is 3–5 mm greater than its width at the back. This joint is connected by fibrocartilage and may contain a fluid-filled cavity; the center is avascular, possibly due to the nature of the compressive forces passing through this joint, which may lead to harmful vascular disease.

In human anatomy, the facial skeleton of the skull the external surface of the mandible is marked in the median line by a faint ridge, indicating the mandibular symphysis (Latin: symphysis menti) or line of junction where the two lateral halves of the mandible typically fuse in the first year of life (6–9 months after birth).

In human anatomy, and in mammals in general, the mons pubis or pubic mound (also known simply as the mons / m ɒ n z /, and known specifically in females as the mons Venus or mons veneris) [1] [2] is a rounded mass of fatty tissue found over the pubic symphysis of the pubic bones.
Mid-inguinal point: A point midway between the anterior superior iliac spine and the pubic symphysis. Intercristal line: A transverse line passing across the lumbar spine between the superior aspects of the iliac crests. Mid-dorsal line: The intersection between the dorsal skin and the median plane.
The pelvic brim is an approximately apple-shaped line passing through the prominence of the sacrum, the arcuate and pectineal lines, and the upper margin of the pubic symphysis. Occasionally, the terms pelvic inlet and pelvic brim are used interchangeably.
A symphysis: connected by broad flattened disks of fibrocartilage, of a more or less complex structure, which adhere to the ends of each bone, as in the articulations between the bodies of the vertebrae or the inferior articulation of the two hip bones (aka the pubic symphysis). The strength of the pubic symphysis is important in conferring ...
