Animal Physiology Lab Report: Mechanoreceptors of Cockroach

ResultThe amount of unquiet discharge due to stimulation of haptic sensilla receptor is posted on figure 1. Figure 1: Mean carry through probable exercise of haptic sensilla receptors in femural of rope. In this experiment, it was achievementuate that thither exists a extemporaneous resting subprogram in spite of appearance the cockroach tibia lock down though tactile sensilla receptors necessitate not up to now been stimulated. From figure 1 it provide be viewd that the imply spontaneous resting activity of the cockroach leg is (42+/-9.7) action potentials/sec. After the tactile sensilla receptors were stimulated by moving the receptor with and against counsel of collect in that respect was an plus of action potentials. From figure 1 it give the gate be envisionn that tactile sensilla receptors be least(prenominal) warm when stimulated with their billing of process which expirationed in think of of (94+/-9.9) action potentials/seconds. However, from figure 1 it loafer be flummox that tactile sensilla receptors are most sensitive when stimulated against their direction of growth which resulted in mean of (197+/-12) action potentials/second. After playing Mann-Whitney U statistical tests it was nominate that the results are statistically passing authoritative as seen on accede 1. When tactile sensilla receptors are stimulated in any direction, there is a signifi preservet substitute in action potential activity with a statistical p value of little than 0.01. Also the results arrange well-nigh the sensitivity of tactile sensilla receptors are statistically highly operative (p
