No. Sinuses are cavities (not bumps) and are located in the front part of your skull behind your eyes and nasal areas.
Not really, there are tiny lumps all over most of it.
They could have been there from birth and grown larger into adulthood and you never really paid attention to them. I have done a lot of research on this and found nothing on this sort of thing. Think about what you have been doing. If the lumps seem to be on the same spot on each side of your skull then perhaps you are wearing a bike helmet or if you are male, helmets in sports and it's irritating your skull causing the lump. It could also be bony spurs, but this is unlikely. Any lumps should be checked out by your doctor.
this is called the Occipital Gonoyle... look it up - very common in men at the base of the neck/skull
Cysts
Yes. An element of scar tissue can build up from the puppies teeth. However, if any large lumps; weeping lumps, or lumps that grow noticeably bigger over time, seek veterinary assistance.
Nothings wrong as long as they aren't massive. It's the shape of your skull!
All fish have a backbone and a skull.
all of them, the brain is inside the skull
the difference between a head and a skull is that a head has tissue and a skull is all bone
To get the first skull on Sierra 117 you have to get to the part where the first brute and grunts are. after you kill them wait for the Phantom to drop more covenant on the ledge below you. KIll all of them, then go to the right to where the tree is and look over the edge. you should see the skull, All you have to do is jump on the rocks until you get to it. From the top of the ledge the skull is about 40 yds. away. (remember you have to be on at least the Normal difficulty to get the skull.) Hope this tip helps. Brassmonkey#10
I believe yes. these can be found all over the body but mostly on the breasts or testicles. Chances are it's just nothing but i would get them checked out.
