I have another break from gymnastics. This is both annoying and pleasant. Joey and I maddened Dad at the beginning of school. We were doing biology and Joey and I couldn't stop laughing about the Babinski reflex. Now if you heard about a reflex that baby have called the Babinski reflex you would laugh too, right? The babinski reflex is a reflex that makes them flex there feet and pull away if you put a sharp object an their feet. If you're not a baby then you curl your feet and pull away. So when I heard it I giggled a little while joey was laughing his nerves off. Joey's laughing was contagious so in the end Dad yelled at us to get us serious and ended the biology lesson. I was very serious in spelling. Dad continued the biology lesson after lunch. We learned about nerves. The sense nerves are put all over the body but in some places more than others. if you take your fingers and put them against someones back they they can be an inch apart, but to the person it feels like one finger. But to the hand you have to have them together. on the cornea it doesn't feel heat but it feels very sharply if anything touches it. The liver only feels if it is being stretched you could burn it or cut it but it would hurt if it was stretched.

Hey Theresa!
ReplyDeleteThat's great that you are learning all this Biology! I learned about the Babinski reflex in my neuroanatomy class last year. Did you learn that this reflex is the reason babies look like they are trying to walk when you stand them on their feet? They can't actually learn to walk until they grow out of it.
