Symphysis OSSium pubis (continued). Its contains nearly constantly within 

 its lamina fibrocartilaginea interpubica a small medianly situated joint slit which lies 

 nearer the posterior margin than the anterior and extends almost over the upper half of 

 the fibrocartilaginous mass; the joint -slit is larger in the female than in the male. 

 The strands of fibrocartilage run in the depth, mostly transversely, between the two layers 

 of hyaline cartilage and are seen on median section to consist of concentrically arranged 

 circular layers. Cartilage and fibrocartilage are very firmly united with one another.
