Frontal bone forms forehead, includes sinuses. (empty cavity, spaces within skull bone.) may
become inflam or infection. Can cause headache. Difficult to treat.

Document Summary
Frontal bone forms forehead, includes sinuses. (empty cavity, spaces within skull bone. ) may become inflam or infection. Examination of the frontal bone, male skull develop crust, ridge above the eye crest. Ethmoid bone, extend into the nasal cavity, dividing the nose into 2 nasal cavity. Projection that comes into the side is conchae (shell), 3 pairs. Tip of your nose is elastic cartilage. (some people don"t like it so plastic surgery, cut and reshape) The nasal bone can regrow and form back into it"s shape, if it is changed through plastic surgery. Difficult to breathe through, may be broken and reset. Fix: breaking ethmoid and vomer by aligning to the midline. Parietal bone form the side of the brain, strong, thick. Separated from the frontal bone by coronal suture. Not midsagittal, but not straight in the middle because it is jagged. Back of the head is the occipital bone, separated by the parietal bone, suture lambdoidal suture.
