1. Explain how cells specialize to form specific tissue and organs. Cells specialize to form specific tissue and organs by stem cells being able to develop into every type of cell in the body and eventually recreate a person’s tissues. With organs, after you gather the cells which can be from the patient’s own organs you have to go towards how they grow and specialise. The cells need to be put in the right environment, and exposed to the forces that they would normally experience in the body.…
Also it can be found in blood vessels and nerves. This tissue can be found in mucous membranes, nerves or around blood vessels. Its functions are to provide strength, elasticity and support to the skin and muscles. d) Compact Connective Bone Tissue: this tissue contains collagen and calcium phosphate which gives to the bone strength and firmness. The functions of this tissue is to support other softer tissues, to protect internal organs, to help in the movement of skeletal muscles attached to bones, to storage minerals such as calcium and phosphorus, to product platelets, blood cells such as leucocytes and erythrocytes.…
Within the epididymis, there are several types of cells that make up the epithelium, some of which are the main, basal, apical, clear, intraepithelial lymphocytes, and intraepithelial macrophages. Clear cells are predominant in the tail region of the epithelium. The ways in which these cells are involved with V-ATPases are as follows. Osteoclasts use plasma membrane V-ATPases to acidify the extracellular space between the bone and cell. This is vital for the resorption of bone.…
City brings her 6-year-old child to see her primary care physician, complaining that her child has seemed “off” for the past month. The child has been extremely fatigued and taking multiple naps during the day that do not seem to refresh her. She is normally a good sleeper at night and recently has begun to have trouble with multiple awakenings. The child has also complained multiple times of frequent headaches throughout the week. She has also been seen to exhibit some confusion while playing in the woods in their backyard with her friends.…
At time=0 minutes, average number of cells were immotile and as we reached closer to time=60 minutes, the cells were becoming motile. Our data in tube #1 (positive control) and #3 shows that the number of immobile cells decreased, which means that the cells were mobile. In tube #1, the cells regenerated their flagella and in tube #3, the cells were never deflagellated so the addition of colchicine did not have an effect on the flagella. Colchicine affects polymerization of flagella, but in tube #3, polymerization already occurred beforehand. The class data shows similar results to our results.…
The Effects of Temperature on Cellular Membranes Kean University: Biology 1300 Section 3 Liyet Iran Partners: Paoline Medina, Jennifer Yuen, Christian Gonzalez, D’wan McCrary, Nicole Piscatelli November 12, 2015 Abstract The cell membrane is an essential structure of any cell. It’s the structure that protects and support the cell. To determine whether this structure can withstand hot or cold environment, a beet specimen is put to test. Six consistent cylindrical beet will each be placed into different temperatures ranging from -5℃ to 70℃.…
To begin this experiment, make sure that the laptop computer is turned on and connect the Conductivity Probe to the computer interface. Set the Conductivity Probe to the intermediate setting, 2000 μS/cm (0 to 1000 mg/L TDS). Open the file “01A Membrane Diffusion” from the Advanced Biology with Vernier folder of Logger Pro to prepare for data collection. The first portion of this experiment will test whether the different concentration gradients affect the rate of diffusion.…
These terminally differentiated cells maintain a columnar alignment in the hypertrophic zone. The processes of chondrocyte proliferation, hypertrophy, and cartilage matrix secretion result in chondrogenesis.…
Description and Prevalence Esophagus is part of the gastrointestinal (GI) system located in the upper body, posterior to the trachea (Huether and McCance, 2012). The esophagus consists of four layers (from outermost to innermost layer): adventitia, musculairis propria, submucosa and mucosa. The submucosa and the mucosa layers are very important because they are the common sites for cancer development.…
Product Description PROKERA® is a therapeutic device used by eye doctors around the world to protect, repair and heal damaged eye surfaces. PROKERA® is made by clipping a piece of amniotic membrane tissue in between two rings made out of a clear, flexible material. What is amniotic membrane tissue? Amniotic membrane is part of the placenta. It is the tissue closest to the baby throughout development in the womb.…
Imagine waking up one day and not being able to walk properly or feeling numbness in your legs. You’ve just experienced one of the most common symptoms of multiple sclerosis (MS). Multiple sclerosis is a lifelong autoimmune disease typically found in young adults. Multiple sclerosis is a degenerative disorder of the myelin sheath. Loss of myelin followed by subsequent lack of neural communication and neuronal death is accepted as the primary cause of disability in MS patients (Dutta 2007).…
How is the membrane structure related to the transport of materials across the membrane? The membrane structure plays an important role in the transportation of materials across the membrane. The Cell membrane is a barrier that separates a cell from its surrounding environment. This is composed of Phospholipids, Proteins, Cholesterol and Carbohydrates. The Membrane Structure has a very important role in the transportation of materials across the membrane.…
The integumentary system is comprised of the skin’s two layers, the dermis and epidermis, as well as hair, nails, glands, and nerves. Underlying the skin is the subcutaneous layer, or hypodermis, this layer is not a part of the integumentary system but is vital to its function. Made up of a layer of loose connective tissue the hypodermis serves to connect the skin to underlying muscle and bone (142). The hypodermis also assists the overlying skin by supplying it with blood vessels and nerves (Vanputte, Regan, & Russo 149). Superficial to the hypodermis is the deepest skin layer, the dermis.…
1.Introduction: Background/Aim. 1.1 Nature of the microorganism: Enterococcus faecalis was placed under group D streptococci because of similar lysis characters; Identified as Gram positive, non-motile, anaerobic fermentative, lactic acid bacteria; are commensal inhabitant of intestinal bacteria and opportunistic pathogens. They occur singly or in pairs or chains. 1.2 Economic importance: Enterococcus faecalis is also used as a probiotic for production of Mediterranean cheese and meat products that is normally responsible for organoleptic nature of final product in fermentation reactions. 1.3 Habitat: Enterococci are extremely hardy microbes such that they are able to inhabit at wide range of temperatures (10°and 45°C), pH values (4•6 and…
The first layer is the endothelium of the capillary. In the glomerulus, this single layer of cells has thousands of gaps. * The basement membrane between the two cell layers is composed of glycoprotein and collagen fibres.…
