Epithelium

It represents approximately one third of the total uterus size, or approximately 2-5 cm long. Approximately half of it lies above the vagina and half extends into the vagina. The cavity is termed the cervical canal. It is a spindle-shaped and communicates with the cavity of the body through the internal os, and with that of the vagina, through the external os. The endocervix is the mucous membrane lining the cervix. The cells of the cervical lining secrete mucus to provide a lubricated surface…

The olfactory system, the sensory system contributing to the sense of smell, is often overlooked by the average person causing distortion as to how it functions, coupled with the gustatory system, to differentiate the different flavors in food which in turn allows us to classify food as delicious, good, unpleasant, or disgusting. In the other hand, the same can’t be said for the food industry, who spent numerous resources into understanding this specific sensory systems with the aim of…

infection. One of the more modern approaches to dealing with a UTI involves the intake of cranberry juice. Studies have shown that cranberries contain a tannin that prevents adhesins from being able to attach to or penetrate the outermost layer of the epithelium. A tannin is a combination of different molecules derived from Gallic acid, and they are common in many plant tissues, including bark, cutaneous tissues enveloping fruits, stems and seeds. Gallic acid is the primary reason that cranberry…

Biology 1A The Biology of Disease Thyroid Cancer Cancer is a disease that plagues many people word-wide and can prove to be extremely deadly with a high mortality rate, or not as much so with a high survival rate. This is because some cancers prove to be more difficult to manage and remove while others do not require to be removed and may just cause minor complications. Thyroid cancer happens to have characteristics from both these types of cancers; it can be subtle and cured easily if caught…

In a DALK graft, only the outermost epithelium and about 80 % of corneal stroma are replaced; the patient's rearmost endothelium layer and the Descemet's membrane are left, giving some additional structural integrity to the transplanted cornea [9]. Comparisons indicate that outcomes are similar…

All five of our different senses are important to have for a variety of reasons. They allow us to see, to feel, to hear, to smell, and to taste. There are also a lot of different parts of the body that allow us to experience these senses. If I had to choose which sense to lose though, I would choose to lose my sense of taste. One of our five senses is taste. The primary function of taste is to have us evaluate what we are eating. There are a few different areas that give us the ability to…

Diets are influential of growth quality and leave imprints on enamel. Consumed substances can have selective effects on different regions of each particular tooth. This can be seen by looking at the topographical variances that are caused by mastication patterns from diets. Mastication forces are applied more heavily in certain areas, where areas of greater thickness endure greater mastication forces. Average enamel thickness, determined with more precise measurements, gave more detailed…

from the soft palate to the hyoid bone and opens anteriorly into the mouth. It contains the posterior third of the tongue, the lingual tonsils, palatine tonsils and the superior constrictor muscle. It is lined by non-keratinized squamous stratified epithelium (Teach me Anatomy, 2017). The oropharynx functions as an airway and as part of the alimentary canal. It works with both the respiratory and digestive systems, and is involved in the voluntary and involuntary phases of swallowing. Because…

are coverd by cilia and microvilli, and represent critical regulators of stem cell self-renewal and neuronal determination by releasing neurogenic factors, such as noggin, which inhibits gliogenesis and promotes neurogenesis [27], and the pigment epithelium-derived factor, which participates in the maintenance of neural precursor cells [28]. Neurogenic niches are closely located to the vasculature [29, 30], where endothelial cells provide an important promotor of adult neurogenesis, the vascular…

Introduction Has environment pressure of sunlight contributed to the variation in iris pigmentation? Only 10,000 years ago, someone who lived near the Black sea developed a mutation, which resulted in blue iris pigmentation (Eiberg, 2008). The iris consists of small connective tissue surrounded by muscular structure with a central opening known as the pupil (Sturm, 2008). This pupil allows the eye to control the amount of light, which enters to allow they eye to focus the lens to the retina.…
