A set of vocabulary flashcards focused on key anatomical terms related to the os coxal.

Os Coxal

The coxal bone; a flat bone formed by the fusion of three primitive bony pieces: ilium, ischium, and pubis.

Acétabulum

A large hemispherical cavity in the lateral face of the os coxal that articulates with the femoral head.

Face Latérale

The lateral aspect of the os coxal that includes the acetabulum, gluteal surface, and obturator foramen.

Surface Glutéale

The lateral surface of the iliac wing, marked by two curved lines for muscle insertion.

Foramen Obturé

A large, oval or triangular hole in the os coxal situated below the acetabulum, providing passage for structures and muscle attachment.

Crête Iliac

The thick, curved upper border of the ilium serving as an attachment site for various abdominal muscles.

Symphyse Pubienne

The cartilaginous joint between the two os coxaux at the front, allowing minor movement.

Articulation Sacro-Iliaque

The joint between the os coxal and the sacrum, facilitating weight transfer from the upper body to the lower limbs.

Ligne Arquée

A curved bony line on the medial face of the os coxal separating the iliac fossa from the space below.

Epine Iliaque

Prominent bony protrusions on the ilium serving as attachment points for muscles and ligaments.

Insertions Musculaires

Points on the os coxal where muscles attach, including muscles involved in hip movement.

Cadre Osseux Ischio-Pubien

The bony structure formed by the ischium and pubis surrounding the obturator foramen.

Tubérosité Ischiatique

The bony prominence on the ischium where muscles of the posterior thigh attach.

Echancrure Sciatique

A notch in the ischium providing the passage for sciatic nerves and muscles.

Angle du Pubis

The angle formed by the inferior rami of the pubis at the symphyse pubienne.
