Incus is the bone which is not connected to the pelvis directly.
The pelvis is the lower part of the torso, between the abdomen and thighs (sometimes called the pelvic region), with an implanted skeleton.
Incus (inclusive) or anvil is the bone in the middle ear. The small anvil-shaped bone is one of the three ossicles in the middle ear.
The incus receives vibrations from the laterally connected malleus and transmits them to the medial stapes.
Incus Bone has several basic regions. One of its surfaces, called the head, articulates with the knuckle of the malleus. The anvil also has two extensions known as the long crus and the short crus.
Long crus have lenticular projections at the ends. This is the hooked part of the incus that articulates with the head of the stapes.
The short crus is attached to the posterior wall of the middle ear cavity where the ossicles are located. The centre of the incus is also called the body.
