There are three atlantoaxial joints: one median and two lateral: The ligaments connecting these bones are: The atlantoaxial joint in common terminology is actually a
Cold and heat adaptations in humans as desert conditions. Dry heat is also very dangerous as sweat will tend to evaporate extremely quickly, causing dehydration. Both humid heat and dry heat favor individuals with less fat and slightly lower body temperatures. When humans are exposed to certain climates for extended periods of time, physiological changes occur to help the individual adapt to hot or cold climates. This helps the body conserve energy. The Inuit have more blood flowing into their extremities, and at a hotter temperature, than people living in warmer climates. A 1960 study on the Alacaluf Indians shows that they have a resting metabolic
