The skull features numerous foramina through which pass the cranial nerves, the spinal cord, arteries, and veins. The temporomandibular joint connects the lower jaw to the temporal bone and enables movement for speech and mastication. The viscerocranium consists of the unpaired mandible and vomer and the paired zygomatic bones, inferior nasal conchae, lacrimal bones, nasal bones, maxillary bones, and palatine bones. These categories are known as: The cranium The facial skeleton. The fontanelles, which comprise the anterior, posterior, and the paired mastoid and sphenoid fontanelles, close between the age of 2 months and 18 months. The human skull bones are divided into two major categories. Teach them that the skull contains eight larger bones that are. The skeletal system can break down into two main categoriesthe axial skeleton.

This is the flat bone that makes up your forehead. The neurocranium consists of the frontal, the ethmoid, the sphenoid, the occipital, and the paired temporal and parietal bones. There are eight cranial bones, each with a unique shape: Frontal bone.
