Question | Answer |
Squama | large part superior to foramen magnum |
Foramen magnum | where brainstem passes through |
Lateral part (lateral mass) | side of foramen magnum |
Basioccipital part (basiocciput, clivus) | articulates with sphenoid? |
Facet for the sphenoid | where sphenoid articulates with occipital |
Occipital condyle | outjuttings on side of foramen magnum |
External occipital protuberance | protuberance located on ectocranial midline above external occipital crest, where occipital and nuchal plates meet—it is exactly at the same location on the skull as the internal occipital protuberance, except on the ectocranial surface |
Internal occipital protuberance | located at center of cruciform (endocranial) |
Superior nuchal line | located below the external occipital protuberance, it lies to either side of the midline on the ectocranial surface of the squamous portion |
Inferior nuchal line | located below the superior nuchal line on either side of the occipital crest |
Median nuchal line | runs through the occipital crest |
Hypoglossal canal | tunnels through the anterior part of the pace (therefore superior in placement) of each condyle |
Posterior condyloid foramen | posterior to condylecircular openings |
Jugular process | |
Pharyngeal tubercle | |
Groove for the sagittal sinus | |
Groove for the lateral (transverse) sinus | |
Occipital crest | |
Jugular tubercles | |
Groove for the medulla oblongata | |
