Purpose: The purpose of this lab is to show reflexes and how the nervous system arcs and nerve impulses work in order to test out a certain reflex.
Hypothesis: The reflex testings’ will show no abnormalities in our nervous system. If we reacted to all the trials then we will not have any abnormalities in our reflexive nervous system.
Materials: Lab Partner
A rubber hammer (Triangular)
A Yard Stick
A chart to record your reflexes
1)
2) When the hammer hits the patella the sensory fiber leads into the central nercous system and connects to one or more interneurons. These interneurons communicate with motor neurons and then leads outward to the effectors.
3) Muscular tension dumbs out the signal responses for reflexes due to the amount of concentration and energy concentrated onto the clenched part of the body. When clenching your fists during a fight or athletic contest your reflexes are not as effective because most of the energy is used to clench your fists.
4) The involuntary jerks in the muscles after the reflex tests are similar in every trial
5) It is hard to catch the card because the reflexes and the impulses do not act quickly enough for us to catch the card within a short time span. The synapse uses chemicals to transfer impulses which slow down the reflex even more.
Results: We obtain misleading results due to the gaps in our lab on how we did not respond to a certain reflex trial.
Problems: We ran into a couple of errors while doing the experiment. Two of our reflex
