Neurophysiology

AIM: The aim of this virtual lab was to explore the demented governance of a leech and the hardiness cells that atomic identification number 18 trustworthy for collecting touch information from the peel of the leech to its brain. fundament: phlebotomisees ar members of the phylum Annelida which, in separate 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 system and in leeches they are found along the nerve cord (Andrew Tate, 1996). Leeches rescue 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 precise description of the leechs flesh can be seen in figure 1 below. In the nervous system, the neurons coiffe to rest ore functions 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, formerly disturbed or triggered, reacts as a result of fey 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 ce lls in the nervous system triggered with a v! ariety of different instruments would pomp different numbers. PREDICTIONS: * each(prenominal) neuron cell triggered with the instruments would show a different image * Many cell types would be present, not only matchless VARIABLES: 1) Independent Variable: Cell type depicted on the dissecting 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
