Reflexes Lab

In this lab, we tested each others reflexes through a serious of activities. A reflex arc is a pathway to nerve impulses which do not go to the brain. The first activity was the photopupillary reflex. We tried to see what light did to your pupils after they were closed for 2 minutes. This was an autonomic reflex because we could not really control what they did. The knee jerk reflex automatically cause your leg to jerk out once it was hit lightly. The blink reflex was also autonomic because our eyes closed as a first instinct to prevent the cotton ball from reaching the inside. The plantar reflex was a somatic reflex because our muscled contracted and flexed by themselves and it was not something we could have controlled. The last activity we did was our reaction time to a ruler when dropped. This was a somatic reflex because it stimulated our skeletal muscles. Texting changed my response time but .1 seconds because i was distracted. My time without texting averaged to .14 and my average time while texting was .24.
This was the class average. Females had a faster reaction while texting than males did but males had a faster reaction time than females without texting.
