What tissue is on the slide? The tissue is ciliated simple cuboidal epithelia. How I identified this? I knew it was epithelia as the cells on the slide were connected to form sheets that were attached to a basement membrane, two characteristics of epithelia tissue. (Urry, L.A. et al., 2017) Epithelia cells are polar meaning that they always have one side of the cell facing a lumen (cavity) which is another way I identified these cells as epithelial. (Urry, L.A. et al., 2017) I identified it was simple epithelia as there was only one layer of cells and they were all connected to the basement membrane. (Urry, L.A. et al., 2017 ) It was identified as cuboidal as the cells looked like squares. They were also identified as this as they had their nucleus placed centrally in the cells. (Mitchell, B.S. & Peel, S 2009) The tissue is also ciliated and this can be seen in the lumen as there are areas that are blurred in the slide which suggest cilia as the cells are smaller that of epithelia.

Simple cuboidal epithelia can be from many glands but since the tissue in the slide is ciliated it is likely to be a gland or organ that would absorb molecules such as kidney tubules, lining of ducts in the liver. (Mitchell, B.S. & Peel, S 2009) (Urry, L.A. et al.,
Question 1: Briefly describe, in 500 words or less, the normal structure and function of your chosen cell type. In your answer, discuss specific features in your chosen cell type, including cell organelles.
Hair is considered one of the components of the integumentary system, along with the skin, nails, glands and nerves. Mammalian hair has many functions including protection from environmental factors and the ability to disperse sweat gland products such as pheromones. Almost every part of the human body is covered by hair except for the palms, hands and bottoms of the feet. On average, every person has about five million hairs; each of these hairs is born from a follicle or tiny tube-like structure that grows into the dermis layer of the skin. Oftentimes this follicle even reaches the subcutaneous layer, which is made of fat and connective tissue. (UXL Complete Health Research, 2001)

Simple epithelia: Epithelia tissue can have cell shapes these are the Columnar, Cuboidal, and Squamous Cell Shapes. All this cells shapes are part of a type of an epithelia tissue which is the simple Epithelia. There are columnar cells, which means column-like cells and squamous cells, which are flattened and scale-like cells, simple squamous epithelia is found in walls of lung alveoli, blood capillaries and bowman’s
The Spleen by Anne Finch, the Countess of Winchelsea, presents an interesting poetic illustration of depression in the spleen. The spleen for Finch is an enigma, it is mysterious, shape-shifting, and melancholic. Melancholy leads the subject to flashes of a grander, terrifying emotion: the sublime. The subject of Finch’s Pindaric ode experiences the sublime, and yet has the uncanny ability to reflect and reason on the feeling with acuity--even though the subject suffers from depression, which in effect dulls sensory information. The fact that she intensely perceives the sublime suggests a paradox where dulled senses can produce a penetrative emotional episode. To understand the paradox, the theory of the sublime and Finch’s engagement with the sublime in The Spleen must be traced to conceive the state of the dulled mind in the thrall of an infinite, and transcendent wave of emotion. The focus of this essay is that Finch understands that Dullness, as a by-product of depression, enables rational thought during a sublime experience. Furthermore, she thus illustrates her experience through images where she emphasizes her sensory information and her feelings, which were supposedly numbed by depression. Her feelings, indicated in The Spleen, are the crux to how Finch is able to simultaneously feel numb, and process the sublime.
Epithelial tissue covers the surface of the human body and lines most internal cavities. Epithelial tissue is found in the body’s skin, lining of the stomach and intestines, the kidney, and glands, as well as other locations within the body (Amsel, 2012). The two types of epithelial tissue are (1) covering and lining epithelium and (2) glandular epithelium. The covering and lining epithelium are found lining the integumentary, digestive, cardiovascular, and respiratory systems as well as the ventral body cavity and the organs this cavity houses (Hoehn, et al., 2007, p. 118). The glandular epithelium is found within the glands of the entire human body. Not only are their two types of epithelial tissue found in the human body, there are also multiple classifications and various shapes. These classific...
Depending of the localization, there are three main types of uterine fibroids (see fig 3)
c solution and sucked up some of the water in the cells. When we observed the cheek cells we found they were very different from the plant cells. The nucleus was in the middle of the cheek cells and there were a few cell organelles. The Planaria cell was all red and had lines running down it.
The reproductive system was mainly located towards the anal area and inferior to the stomach. The penis was located in the middle. It was white in color and looked like a mealworm. The seminal vesicles were located on both sides of the penis. They were grayish pink in color and looked like walnuts.
The placenta is composed of two structures: the maternal decidua basalis and the foetal chorion composed of the foetal membranes such as the syncytiotrophoblast. (University of Michigan Medical School, 1999...
The kidneys lie on the posterior abdominal wall, with one on each side of the vertebral column, and are held in position by a mass of fat called ‘Adipose’. (Innerbody.com, 1997). Kidneys are the primary organs of the urinary system that filters waste, water and electrolytes from the blood forming urine, through a continuous process called ‘Filtration’. (Innerbody.com, 1997). Each kidney has millions of nephrons, these are the functional units of the kidneys where filtration takes place. (Freudenrich, 1997). Nephrons have three functions known as Ultrafiltration, Selective reabsorption and tubular secretion. They are lined with a cellular membrane called ‘Microvilli’, this increases the surface area within the tubule to enable substances to secrete and reabsorb the filtrate. (Innerbody.com, 1999)
All types of cilia have a length of about 10-15 μm and comprises of the same basic structure. A cilium is a microtubule-based organelle, which extends from a microtubule organizing chamber- the basal body, a centriole and at the apical surface of the cell bears microtubule cytoskeleton called the ciliary axoneme surrounded by a specialized ciliary membrane. The primary or the non-motile cilia consist of the ‘9+0’ arrangement of the axoneme, with the normal nine outer microtubule doublets and no central microtubule pair. Since the primary cilia are non-motile, therefore they usually lack dynein arms and radial spokes connected to the microtubule doublets. Primary cilia can receive signals from the extracellular biochemical and physical environments. Nodal cilia like primary cilia, occur solitary, having the 9+0 arrangement of axoneme, however, nodal cilia bears L, R...
Dynamic equilibrium functions in the three semicircular ducts, the saccule and the utricle. The two ventical ducts are the anterior and posterior semicircular ducts. The lateral semicircular duct is horizontal. In the dilated portion of each duct, the ampulla, is a small elevation called the crista. This contains hair cells and supporting cells which are also covered by a mass of gelatinous material which is called cupula. When the head moves the attached semicircular ducts and hair cells move with it.
Geographical processes can result in the creating of magnificent landscapes that one would expect to see in a sci-fi movie or read of in a fairy tale. A wonderful example of such a natural creation is the complex yet intriguing region of Cappadocia, Turkey. It is riddled with bizarre sites such as mushroom rocks, pillars and the tunnels that were once the largest underground city. Nature has shaped and allowed humans to shape this area into a natural and historical landmark. This essay will examine the history behind the human creations here and the geography that allowed them to happen as well as the naturally occurring features.
