Answer 2

The Most Protective Body Cavity

Answer 3

Great question!

My first impulse answer is the cranial cavity. Of course I'm also considering that the the cranium has a blood-brain barrier too. So its protected on the outside and the inside.

In my mind its pretty obvious the abdominal-pelvic cavity (which includes the abdominal and pelvic regions, so I guess this is sort of a trick question) it not well protected. There are few bones that area that protect, but rather offer support (or they offer protection for cranial extensions).

Although the vertebral cavity (which includes both dorsal and ventral [another trick question]) is well surrounded by bone, and then muscle, they still seem to be a source of problems for many people. Maybe its the way that the bone surrounding the vertebrae articulates. Its not smoothe bone (like the skull), its bone with lots of protrusions.

I guess I will stick with my first answer. Because the smooth bone seems to offer the best protection.

Plus between the bone and the brain is a cushion, so in case the brain is forced to move suddenly, it has a water bed to soften the blow.

Thanks for asking this question. I learned a lot.

Pass on the good Karma!

Answer 4

Gotta be the cranial...it is completely surrounded by bone except for the foramen oval, where the spinal cord starts.
