Neurophysiology

AIM: The aim of this virtual lab was to explore the queasy agreement of a leech and the pump cells that atomic tour 18 trustworthy for collecting touch information from the discase of the leech to its brain. fundament: poriferanes be members of the phylum Annelida which, in different words, are section worms (Satoshi Amagai et.al, 2012). The medicinal leech used in hospitals for its anesthetic properties has 34 Ganglia. Ganglia are a bundle of nerve cell tissues which are non central to the nervous dodge and in leeches they are found along the nerve cord (Andrew Tate, 1996). Leeches ca-ca a brain unlike some of the invertebrates such as the squid( go in 2).Also, the leeches conk to a minority called class Hirudinea (Satoshi Amagai et.al, 2012) and they are distinguished by the suckers at the ends of their bodies. A tiny description of the leechs figure of speech can be seen in figure 1 below. In the nervous system, the neurons service of process to restore fu nctions if disturbed, as a sign of negative feedback. Neurons are cells which carry out galvanizing impulses throughout the nervous system(Minka Peeters Weem et.al,2008).The leech, at a time disturbed or triggered, reacts as a result of touched(p) neurons and sends information from the ganglion to the brain and in conclusion results in a reaction (Dr.Richard Emes et.al, 2012). Figure 1: flyaway system and anatomy of a medicinal leech (Andrew Tate, 1996). Figure 2: Leech Anatomy (Aaron Harden, 2012). HYPOTHESIS: If the dyed canvas shows the nervous system of the leech then the different cells in the nervous system triggered with a variety of different instruments would pomp different renders. PREDICTIONS: * distributively neuron cell triggered with the instruments would show a different image * Many cell types would be present, not only sensation VARIABLES: 1) Independent Variable: Cell type depicted on the dissectin g microscope (Type N, T, P, X or R) 2) ! Dependent Variable(s): *...If you want to drag a full essay, order it on our website: OrderCustomPaper.com
