I decided to palpate the spine of the scapula. I did this because the scapula is more defined in the back making it easier to feel on my partners back. I was able to locate the scapula on the rib cage and also the scapulae surface. I was capable of palpate the indentations at the superior and inferior halves of the bone as well. The easiest place to palpate was the scapula surface. The surface was very visible when my partner extended his arm out to his side. The most challenging to palpate was the indentation because I had to really feel for it. Even with my partner extending his arm out I could barely find it. I had to have my partner put his arm down and extend it back out to find the indentation. Lab Report A chicken wing bone
The unknown bacterium that was handed out by the professor labeled “E19” was an irregular and raised shaped bacteria with a smooth texture and it had a white creamy color. The slant growth pattern was filiform and there was a turbid growth in the broth. After all the tests were complete and the results were compared the unknown bacterium was defined as Shigella sonnei. The results that narrowed it down the most were the gram stain, the lactose fermentation test, the citrate utilization test and the indole test. The results for each of the tests performed are listed in Table 1.1 below.
The protocol and conceptual overview of these procedures can be found under the header, “Properties of Skeletal Muscle” in NPB 101L Physiology Lab Manual Second Edition (Bautista & Korber, 2009, 9-17). The test subject for this lab was the Northern Leopard frog whose spinal cord and brain were severed. In order to carry out the experiments, the materials needed were one medium length surgical scissor, two hemostats and glass dissecting probes, a nine and four inch string, a cup of Ringers saline solution with an eyedropper, and a hook electrode. The software used to analyze and record the data was the BIOPAC system.
Planarians are free-living, carnivorous flatworms found in the Phylum Platyhelminthes, Class Turbellaria. Although the Phylum Platyhelminthes is known for having the animals with the most parasitic species, the class Turbellaria which consist of the Planaria, are a non-parasitic species. Platyhelminthes which translates to "flat worm" are triploblastic animals. This means that they have three tissue layers, the endoderm, mesoderm, and ectoderm. Planaria also are monoecious organisms, meaning that they have both female and male sex organs in one organism. Another characteristic of the Planaria is that they do not have a true body cavity, meaning that they are acoelomate organisms.

The purpose of this lab was to study the response of the genus Daphnia to chemical stimuli and to examine human responses to different stimuli. A stimulus is an incentive; it is the cause of a physical response. Stimuli can have a physical or chemical change; an example of a physical change is a change in temperature and sound. An example of chemical change would be changes in hormone levels and pH levels. Muscular activity or glandular secretions are responses that occurs when stimulus information effects the nervous and/or hormone system. Daphnia is a genus; it is a small crustacean that lives in fresh water. The body of the daphnia is visible and its internal organs are clearly seen thus it was chosen for this exercise. The
Many advertisements sometimes mislead its consumers when selling out protein powder products. One particular manufacturer is claiming that when testing 1 gram of Tough Guy protein powder in 100 ml of H2O, the final concentration would measure between 0.40 mg/ml protein. To determine if the manufacturer is claiming to be true or not an experiment was conducted. By determining the amount of protein that is presented when Tough Guy protein powder is diluted in water by adding Bio-Rad assay (measuring the concentration of protein within a known and unknown samples). Measurement of color change will be needed by placing the solution into a spectrophotometer at 595 nm. Thus, determining its results.
The vertebral column is composed of seven cervical, twelve thoracic, five lumbar, five sacral, and four coccygeal vertebrae. The lumbar vertebrae are numbered from one through five starting with the highest vertebrae, and preceded by the letter L. (i.e. the lowest vertebral body will be represented as L-5) Between the vertebrae of the cervical, thoracic, and lumbar regions are invertebral discs that serve as shock absorbers that allow the everyday movements of the spine. Discs themselves are represented by naming both of their adjacent vertebral bodies (i.e. a lumbar disc is can be identified as L-4 L-5 or L-4,5). The discs are made up of an outer ring of more dense material called the annulus fibrosus. The annulus fibrosus helps to contain the inner gelatinous material called the nucleus pulposes. Upon a stressful movement of the spine, the nucleus pulposes may rupture through the annulus fibrosus posteriorly toward the spi...
Planaria are one of many free-living flat worms that can be found in marine, aquatic, and terrestrial environments. Certain characteristics of planaria worms include an acoelomate body, a gut with no anus, lack of a blood vascular system, and a simple nervous system. The main reason as to why planaria are subjected to many studies is because of their unique ability to regenerate. Regeneration is the ability to re-grow lost body parts that may have been cut off. This is possible because the organism has the ability to form a blastema, which is an accumulation of undifferentiated cells, at the site of the wound. Regeneration is capable of occurring at various degrees throughout the animal kingdom. This unique process would never be able to be seen in human beings. Humans and other mammals
The collarbone is a big doubly curved long bone that joins the arm to the trunk of the body.Based directly above the first rib it keeps the scapula in place so that the arm can hang freely.
The results supported our prediction, the Daphnia treated with alcohol had a decrease in the heart rate. Ethanol slows heart rate. The 10% ethanol was used in this experiment, the ethanol depresses the nervous system by acting as a non-selective neuro-depressant. The amounts of ethanol necessary to achieve this effect in humans would also be sufficient to depress the respiratory centers of the brain, rather like the effect of an overdose of general anesthetic, resulting in death (GCSE Science).
A minks body function has similarities as a humans body, therefore, we use minks as a understanding of the human anatomy.
When the lab began, we went outside and collected our oven mitts. Then, we were handed our bag of supplies. Students were allowed to take the twist tie off without our oven mitts on, but as soon as we finished, we had to put them on. I then took out my paper and bamboo sticks. I attempted to stick them into the dirt, but the soil was too hard. I tried to tie the sticks together with a twist tie at the top, but the oven mitts prevented me from doing that.
The first step was to obtain the White Rat and to tie it in the supine position, anterior surface facing up in side the dissection pan. To tie the animal, we used butcher’s twine and secured the front and hinds legs using a “lasso” technique, careful not touch the sharp claws. To make the first insicion I had to locate the Xifoid Process of the rat (distal aspect of the sternum). Once I had located the Xifoid Process, I had to use forceps to pull the skin of the animal’s abdomen up and use the scissors to cut. The first incision is made from stem to sternum, cutting through the errectos abdomen muscle down to the groin. The second incision ion is perpendicular to the first below the diaphragm. Because of this technique we were able to open the abdominal cavity first. The third and forth incisions were made bilaterally above the legs. The last two incisions were made in upside down “V” shape on the collarbone, to expose the thoracic cavity. This dissection was both sharp, because of the use of the scissors and scapel and blunt because of the use of the probe and forceps to move organs and skin to expose other organs not yet identified.
Introduction According to an online lab manual, Kirby-Bauer test is a highly standard test used in many labs for antibiotic susceptibility for many years. The use of this test is to determine the sensitivity or resistance of bacteria to antibiotics. It is a highly standardized procedure that makes use of Mueller-Hinton agar. For basic a bacterium is swabbed on the agar surface, and then antibiotic disc containing certain concentrations are placed on the center of a plate, pressed firmly so they don’t move, and then incubated.
The Cell, the fundamental structural unit of all living organisms. Some cells are complete organisms, such as the unicellular bacteria and protozoa, others, such as nerve, liver, and muscle cells, are specialized components of multicellular organisms. In another words, without cells we wouldn’t be able to live or function correctly. There are Animal Cells and Plant Cells. In Biology class the other day we studied the Animal Cell. We were split into groups of our own and we each picked a different animal cell slide to observe. My group chose the slide,'; Smeared Frog Blood ';.
