I know there's already a forum for sore and tender scalps but naturally, I can't find it! I needed to register before posting...so it's GONE. For about a year my scalp has been so sore and so tender that it hurts 24 hrs a day. At first I thought perhaps I was allergic to my shampoo so I changed brands. No improvement. Next I wondered if my shower was too hot.
Although small in size, the eye is a very complex organ. The eye is approximately 1 inch (2.54 cm) wide, 1 inch deep and 0.9 inches (2.3 cm) tall. The tough, outermost layer of the eye is called the sclera. It maintains the shape of the eye.
Researchers from the UK have identified other differences. They measured the orbit size (eye socket) of 32 anatomically modern human and 12 Neanderthal skulls from Europe and the Near East. These remains date between 27,000 and 75,000 years in age. The researchers used orbit size as a proxy for eye size, noting that a tight relationship exists between primate eye size and the cortical primary and downstream visual areas of the brain. Neanderthals possessed larger eye sockets than modern humans.
