The different chemicals that were used in this experiment were Pilocarpine, Atropine Sulfate, Epinephrine, Digitals, Potassium, Sodium, and calcium ion concertation. Pilocarpine stimulates the effect of parasympathetic nerve stimulation by enhancing acetylcholine release. Atropine Sulfate is a drug that blocks the effect of the neurotransmitter acetylcholine which is liberated by the parasympathetic nerve endings. Cardiac muscle and skeletal muscle are both different in functionally and in fine structure. Epinephrine is the fight or flight neurotransmitter that is released to increase awareness. Digitalis is a drug that is prescribed for heart patients with congestive heart failure. In cardiac muscle, it depolarizes spontaneously in the absence of external stimulation while skeletal muscle is electrically stimulated. Automaticity is due to the plasma membranes that have reduced permeability to potassium ions but still allow sodium ions to slowly leak …show more content…
The pilocarpine makes the heartbeat slowdown, which was proven to be correct in this experiment. The chemical atropine makes the heartbeat go up and was proven true in this experiment. Epinephrine, makes the heartbeat increase massively, and was proven correct in this experiment. The digitalis, make the heartbeat decrease and was proven in this experiment. Calcium ions make the heartbeat decrease, and this was proven to be true through this experiment. Sodium ions make the heartbeat decrease, and was proven correct in the experiment. Potassium ions make the heartbeat decrease, and this was all proven to be true through the experiment. All the ions make the heartbeat decrease, while all the chemicals made the heartbeat increase. Going into this experiment, I didn’t think that all the chemicals would be proven correct. I thought that some would have been proven to be false or increase/decrease way more than they

    Sasha Scanlon WCCC/ Spring Semester 2015 A&P II/ Matt S. The Effects of Varied Substances on a Daphnia’s Heart Rate. Introduction: The purpose of this experiment was to compare the resting heart rate of a Daphnia, to its heart rate after 5 different substances were tested on it: Aspirin, Nasal Spray, Alka Seltzer, Coffee and Tea. Daphnia’s are often used as an experimental animal in lab settings because they are small, have a short life span and are easily maintained, only needing water to survive. For this specific lab, it was important that we have a test subject whose heart is visible under a microscope.…

    There are three types of muscles in the human body: cardiac muscle, smooth muscle and skeletal muscle. For the purpose of our lab we will be focusing only on skeletal muscle. Skeletal muscle is the only voluntary muscle tissue found in the human body. They're attached to bones by tendons and are responsible for all the movements that are consciously controlled such as writing, walking, running, etc. [1].…

    Predatory Conus Hormones

    2.0 Experimental Approach Predatory cone snails (genus Conus) produce a rich array of venoms that collectively contain an estimated 100,000 small, disulfide-rich peptides (i.e., conotoxins, or conopeptides). Over the last few decades, the conopeptides have revealed a remarkable diversity of pharmacological function and utility. An evolutionary rationale for the existence of such a large and pharmacologically diverse set of gene products can be premised on the complexity of intra- and interspecies interactions that define the ecology of Conus snails. Insights into these evolutionary trends, moreover, have been exploited with great neuropharmacological success, so that research into the Conus snails effectively recapitulates a new concerted…

    Calcium channel blockers can also cause side effects, and may need to be avoided if you have heart failure or low blood pressure. Sometimes medications or cardioversion to control atrial fibrillation does not work. In those cases, the doctor may recommend a procedure to destroy the area of heart tissue that’s causing the erratic electrical signals and restore the heart to a normal rhythm. These options can include: • Catheter ablation. In many people who have atrial fibrillation and an otherwise normal heart, atrial fibrillation is caused by rapidly discharging triggers, or “hot spots”.…

    Summary Of Daphnia's Heart Rate

    It was expected that caffeine would raise the heart rate even more than it did. Our results indicate that the heart rate only went up a very small margin of 2%. This reason was not significantly higher than its base rate could be that the daphnia was stressed from already having other chemicals given to it. It also could have been stressed from the beginning due to being squished by the petri dish cover and this would have given us a higher baseline heart rate to begin…

    Atropine Inhibition

    Lignocaine is a widely used local anaesthetic. This drug shows inhibition of peristalsis due to its ability to block sodium ion protein channels in the nerves of the body. This prevents the initiation and rapid increase of nerve action potentials, this allows for its use as a local anaesthetic by acting on nociceptive neurons (Dale et al., 2015). This will then result in diminished amplitudes of contractions and indicates that only partial inhibition was occurring.…

    Homeostasis Blood Pressure

    Blood Pressure Blood pressure , as a physiological variable of humans, is a hydrostatic pressure, utilized by blood on the walls of blood vessels.(Tortora and Derrickson 2011). It is caused by the contraction of the ventricles and the amount of blood in the whole cardiovascular system. The mean blood pressure (the average pressure in the cardiac cycle) is coordinated in order to provide adequate blood transfer to the tissues.(Saladin,2001). The decrease of blood pressure is followed by an increase of heart rate. The normal blood pressure is 120 mm HG systolic and 80 mm HG diastolic blood pressure There are three main types of blood pressure regulation considering homeostasis: Neural regulation…

    Gastric Secretion Research Paper

    The regulation of acid and pepsin secretion is associated with a balance of chemo-transmitters delivered to the gastric mucosa by pathways that facilitate stimulation and inhibition. The physiologic stimulation of acid secretion is divided into the cephalic, gastric, and intestinal. The main component of gastric secretion is HCL which is a product of the parietal cells. The parietal cells are epithelial cells that secrete HCL and essential factors. Parietal cells are located in the gastric glands in the lining of the fundus and in the body of the stomach.…
