  • Each innominate consists of ilium, ischium, and pubis and bears an acetabulum for the femur, as it does in land mammals.

Examples

  • The sacrum and left and right innominates form a strong and rigid bony girdle that anchors the hind limbs and supports much of the body in locomotion.

    Academic text (2001)
  • The femur (Fem.) is substantial in size, and there is a strong, weight-bearing joint between the sacrum and innominate (Inn.).

    Academic text (2001)
  • In modern whales, in contrast, the sacrum cannot be recognized, as there are no fused vertebrae and no vertebra has a joint for the innominate.

    Academic text (2001)
  • The innominates are not connected to the vertebral column, but these whales retain femurs that are longer than in modern cetaceans.

    Academic text (2001)
  • The sacrum comprises four fused vertebrae, and these articulate with the innominate bones (Figure 11).

    Academic text (2001)
  • In fact, the innominate in modern cetaceans is a tiny bar of bone lacking an acetabulum and distinct ischium, pubis, and ilium.

    Academic text (2001)
  • The sacrum is a series of vertebrae (five in humans) that are fused to each other and connect to the innominates at the first (most anterior) of these vertebrae.

    Academic text (2001)
  • The innominate bone plays a crucial role in the structure of the pelvis, allowing for movement and support during walking.

  • At birth, the innominate is made up of three separate bones, which eventually fuse into a single bone known as the hip bone.

  • Surgeons often examine the innominate to assess pelvic stability and to plan hip replacement surgeries.

Morphology

innominate = nominate (opaque) = in + nominate

Though analyzable as 'in-' + a naming root historically, the anatomical sense 'innominate bone' is specialized and not inferable from the parts by general learners.

Etymology

Innominate comes from Latin parts in- 'not' and nominare 'to name', so it means 'not named'. In anatomy, the noun innominate was used for the large hip bone when it did not have a special name.
