Muscular System Lab Report
The vertebral body is made up of different types of muscular systems that allow the body to maintain posture, move and also circulation of the blood. In this experiment, we focused primarily on the skeletal muscle system. The skeletal muscles work simultaneously with bones of the skeleton. The muscles are able to attach to the bones through tendons. They are under voluntary control of the Peripheral Nervous System and specifically the Somatic Nervous System. Through this joint association, both the skeletal muscles and the bones allow the animal to perform mechanical movement of the body. On a microscopic level, skeletal muscles are composed of muscle fibers, which are also known as muscle cells that allow the muscle to appear striated.
Unit 4 P4 Research Paper
1903 Words | 8 PagesP4 – Describe the three structures of the skeletal muscle (Epimysium, Perimysium and Endomysium) There are three structures of the skeletal muscle: Epimysium is a thick layer of irregular connective tissue that pulls the entire muscle as well as protecting the muscle from friction that may be caused by other muscles and bones surrounding them. Also, it is the fibrous tissue which covers and surrounds skeletal muscles. The Epimysium carries on past the end of bones in order to create muscle tendons. Perimysium surrounds a bundle of muscle fibres, it is a casing of connective tissue.
Jelly Bones Lab Report
666 Words | 3 PagesOn Januray 26, 2023, Jelly Bones was found dead in room W1106, a lab in Huntley Highschool’s science wing. The victim was a caucasian female who appeared to be roughly in her mid to late teens with straight, shoulder length blonde hair. When investigator’s arrive on scene it seemed evident that a homicide had occured in the school. The body was discovered by chemistry and foirensic science teacher Mrs. Zuniga, lying unresponsive in the lab. The victim was wearing light blue jeans with a pale gray colored t-shirt.
Sports Suspension Lab Report
519 Words | 3 PagesThe experiment overall was nicely conducted, and results were found through the information gathered. The dependent variable was established very quickly; furthermore, we can find the dependent variable was whether the athletes played a contact sport or a sport like baseball, where most concussions come from being hit by the ball. The independent variable is the number of concussions the test subjects obtained. Ultimately they could not control how many concussions each individual obtained but they controlled which individuals were chosen and what test were ran. The results that ran throughout the whole experiment was an overall success, the results show that multiple compared to single occurring concussions do not have an effect on P3 suppression.

Lab Report
1244 Words | 5 PagesST Report In the experiment, the problem was the contaminants that were affecting the quality of the water samples. To fix this issue, three scientists had to determine the contaminants that were present in the samples. One sample was from the school sink and the second sample was from an unknown source. The scientists conducted many tests to figure out what pollutants were present in the water.
Virtual Skeleton Lab
333 Words | 2 PagesIt is also noted that where two bones meet is called a joint. There are many types of joints that allow for the body to move in different ways, notable ones: hinge, ball and socket, pivot and some in the skull. The materials used was a virtual skeleton, a cursor, a box, bones, and brains.
Skeletal Muscles Lab Report
1007 Words | 5 PagesPhysiology of Skeletal Muscles L. D.G. Valerio, C. M. Villegas, R. H. Vito, L. R. Zamora Department of Biological Sciences, College of Science, University of Santo Tomas, España, Manila, Philippines Keywords Skeletal Muscles, Twitch, Kymograph, Fatigue, Ringer’s solution Summary The experiment was conducted to be able to determine the effect of graded response, load, pules, frequency, tetanus and muscles fatigue on the contraction of the muscle, specifically the gastrocnemius, by doing the procedures and a series of experiments to get various data. Introduction First we ask the question, what is a kymograph?
Summary: Skeletal Muscles
1789 Words | 8 PagesFile one Summary: Skeletal muscles are made out of striated subunits called sarcomeres, which are made out of the myofilaments actin and myosin. Skeletal muscles contain myofibrils. Every myofibril is striated with dull and light bands. I bands contain just thin fibers, made fundamentally out of actin.
Tn 4351 Unit 5 Lab Report
506 Words | 3 PagesTn 4351 was originally isolated from bacteroides fragilis [30] . The transposon was successfully introduced into Cytophaga succinicans, Flavobacterium meningosepticum, Flexibacter canadiansis, Flexibacter strain SFI and Sporocytophaga myxococcoides by conjugation [25]. Tn 4351carries two antibiotic resistance gene. One of the codes for resistance to erythromycin and clindamycin which is expressed in bactroides but not in E.Coli. The other gene codes for resistance in tetracycline and is expressed in aerobically grpwn E. coli, but not in anaerobically grpwn E. coli or in bacteroides.
Bio 13 Lab Report
1009 Words | 5 PagesIn this three-week long experiment conducted in the Bio 13 Lab, we were able to analyze a single nucleotide polymorphism (SNP) in our own genomic DNA and then determine our genotype at this specific SNP. In week one, we extracted genomic DNA from our cheek cells with swabs and prepared our DNA for PCR (Polymerase Chain Reaction) that would amplify the region with the intended SNP of interest. After one week and after the PCR was run outside of the lab section, the resulting PCR product was purified and treated with restriction enzyme Ahdl in order to prepare for the final analysis of our genotypes. In the third and final week of the project, we analyzed our PCR products by means of agarose gel electrophoresis. By the conclusion of the experiment, we had completed the analysis at the SNP of interest and determined our genotypes for this SNP.
Heart Rate Lab Report
1675 Words | 7 PagesConclusion: In conclusion, as doing a jump rope increased the heart beat per minute and as doing more numbers of exercise, that increased the heart rate even more. In the first graph above (Average initial heart rate VS Average heart rate after jumping), all the blue bars are below the green bars, this represent that no matter the amount of exercise, in all set, the heart rate anyway increased. The result showing in the first graph transformed into a second graph in order to show the changes of heart rate: In the second graph, the average change in heart rate is continually increasing as doing more numbers of jumps. The reason of why this relationship between the numbers of jumping and average change of heart rate is showing as increasing is because of heart beat and exercise are related.
Heart Rate Lab Report
381 Words | 2 PagesIn the experiment, I thought that running in place would raise your heart rate, and that proved to be true. In our experiment group members ran in place for five minutes and took their heart rate every minute, and at the end of five minutes every group member’s heart raise rose. After five minutes one group member’s heart rate rose from 100 beats per minute to 176 beats per minute, an increase of 76 beats per minute. Another group member had their heart rate raise from 60 to 88 beats per minute, an increase of 28 beats per minute.
Mri Machine Lab Report
889 Words | 4 PagesChemical Technology of MRI Machines In Chemistry there are multiple forms of different chemical reactions for a variety of reactions. In order to have a chemical reactions there must be a subject in which will be examined on how it was formed and the stages it has went through. For every chemical reaction, it requires at least two reactants or more in order to combine to form the final product of the subject. For instance, MRI machines are used on a day to day basis because of its effective results, but how is an MR image created?
Biochemical Test Lab Report
1371 Words | 6 PagesBiochemical tests are the tests used for the identification of bacterial species based on the differences in the biochemical activities of different bacteria. Bacterial physiology differs from one species to the other. These differences in carbohydrate metabolism, protein metabolism, fat metabolism, production of certain enzymes and ability to utilize a particular compound help them to be identified by the biochemical tests. Gram’s stain was originally devised by histologist Hans Christian Gram in 1884. Gram-positive bacteria stain purple, while Gram-negative bacteria stain pink when subjected to Gram staining.
