The acetabular fossa is the non-articular depressed region at the centre of the floor of the acetabulum.It is surrounded by the articular lunate surface. [1]: 1368 [2] The floor of the fossa is formed mostly by the ischium; [2] it is rough [1]: 1354 and thin (often to the point of transparency).
It forms an incomplete ring that is deficient inferiorly - opposite the acetabular notch. The lunate surface surrounds the central, non-articular depression - the acetabular fossa - which does not make contact with the femoral head in the articulated hip joint. [1] Its surface consists of articular cartilage.
The acetabulum is also home to the acetabular fossa, an attachment site for the ligamentum teres, a triangular, somewhat flattened band implanted by its apex into the antero-superior part of the fovea capitis femoris. The notch is converted into a foramen by the transverse acetabular ligament; through the foramen nutrient vessels and nerves ...
The acetabular notch is a deep [citation needed] notch in the inferior portion of the rim of the acetabulum. [ 1 ] : 1354 It is bridged by the transverse acetabular ligament , converting it into a foramen (through which nerves and vessels (including the acetabular notch of obturator artery [ 1 ] : 1250 ) pass into the hip joint cavity).
Trochanteric fossa; Linea quadrata; Quadrate tubercle; The head of femur, which articulates with the acetabulum of the pelvic bone, composes two-thirds of a sphere. It has a small groove or fovea, connected through the round ligament to the sides of the acetabular notch. The head of the femur is connected to the shaft through the neck or collum ...

On a map showing only volcanic rocks, the west coast of North America shows a striking continuous north–south structure, the American Cordillera. The North American Cordillera extends up and down the coast of North America and roughly from the Great Plains westward to the Pacific Ocean , narrowing somewhat from north to south.
