why does our knee have a reflex to kick when you get hit in the kneecap? any other reflexes we have like this?
In: Biology
We are born with many Primitive Reflexes but most of them eventually integrate and no longer respond in the same way to the stimulus. A very well known one is when you put your finger in a baby’s palm and it curls its own fingers around it. But there are more – for example, if you simulate dropping a baby (don’t actually drop it), it will throw all of its limbs out and straighten its spine. Similarly, running your finger down the sole of a baby’s foot will make it curl its toes and spread them. Most of these seem to be leftover from evolution and most integrate by toddler/early childhood age. Google “Primitive Reflexes” to learn more 🙂
