Patellar Reflex Lab Report

Discussion
In the patellar reflex experiment, the class results have shown the reaction is faster with performing the Jendrassik's maneuver. Our group hypothesis was proven incorrect. The source of error in this experiment would be the subject can easily control the skeletal muscles which would be voluntarily because the subject was not blindfolded. Therefore, the subject can see the rubber coming at their knee and is expecting the knee to jerk. It's hard to consider this exact result when the subject can control their movement. Using the experiments provided in the lab such as ruler measuring how far the knee jerks can also be very inaccurate because the leg moves up and back fast, it's hard to get an exact measure because the leg did not
Sensory tactile reflex reaction time is faster than auditory and visual. The speed of somatic auditory reaction reflex reaction plays an important role, is essential in humans everyday life, and to prevent further injuries. For example. if the subject touches a hot boiling kettle their initial reactions steps are: 1) somatic receptor received stimuli a "danger" stimul 2) afferent nerve senses signals to CNS 3) integrate information to decide what to do next 4) efferent nerve carry motor impulse ti muscle 5) effectors then will quickly remove hand away from kettle to aggravate anymore pain. In contrast, slow reaction time may come with unaffordable consequence. the given example is not only crucial but it is also a nature reflex that are quick, involuntary (sometimes), stereotyped reaction of muscles to stimulation. Furthermore, sensory tactile must be faster that visual and auditory because we live in a everyday exposed environmental life: externally (sensory tactile) we have to react fast to any stimuli to integrate and protect yourself. Unlike visual and auditory sensory reflex is slower and have time to process to react to a stimuli. In conclusion the result of our hypothesis is proven that tactile sensory reflex reaction time is
