connection to tongue muscle - temporal bone
Petrous Portion
hill that contains inner ear + carotid artery - sphenoid bone

Anterior fontanel
frontal bone + 2 Parietal bone (before it becomes coronal suture) closes up between 1.5 - 2 y.o.
Posterior Fontanel
Parietal + Occipital before it becomes lambdoidal/ 2 months old
Anterolatteral Fontanel
frontal + parietal + temporal + sphenoidal/ up to 3 month old
posterolateral fontanels
located laterally among
the parietal, occipital, and temporal bones, are irregularly
shaped. They begin to close 1 to 2 months after birth, but closure is generally not complete until 12 months.
Hyoid bone
doesnt joint other bones, stable with tongue muscles, connects to throat cartilage. moves tongue muscles and stables throat muscle/, swallowing
