foramen magnum, where brainstem and spinal cord meet occipital condyle, articulates with first cervical vertebrae external occipital protuberance, midline projection on posterior surface

Palatine Bone

forms anterior roof of mouth forms a very small portion of inferior orbit L-shaped bones

Nasal Bone

forms bridge of nose
