Regeneration of the axolotl is dependent upon the blastema (Aguilar et al 2015). The blastema formation takes place during dedifferentiation. (Satoh et al 2010). The blastema is formed from progenitor cells in the uninjured limb by re-expressing embryonic genes. The origin of these blastema cells are controversial, as many have a hypothesis of where are originally derived. (Whited & Tabin 2009). For instance, Aguilar et al (2015) suggests that the formation of the blastema is dependent on nerve…

The skin protects you from ultraviolet radiation because the melanocytes, cells in the epidermis, produce melanin which is a pigment that gives skin its color. Melanin is an absorbent of light and is able to dissipate most of the absorbed UV radiation. It is for this reason that people with more melanin, a darker skin color, have a lower rate of skin cancer than those who have less melanin. The epidermis is the outer layer of the skin and it serves to protect us from the harsh outside world. The…

The skin is a major component of the integumentary system and forms a defensive barrier that protects the internal environment against external forces (Seeley, 2008). Studies carried out by Lowes, Suárez-Fariñas, and Krueger (2013), Cargill et al. (2007) and Tsoi et al. (2012) show that psoriasis vulgaris is a homeostatic disorder of the skin that interrupts the normal proliferation, differentiation and maturation of epithelial cells in the stratum corneum. The focul site of psoriasis vulgaris…

1. A neighbor is walking her dog to the park during her lunch break on a beautiful sunny day. Explain how her skin is working to protect her from ultraviolet radiation due to intense sun exposure. Be sure to discuss the specific structures and substances involved in this protection. Given that skin is broken down into three layers, the layer of the skin that would be directly exposed to the ultraviolet radiation from the sun is the epidermis. Her skin has melanin in it which protects it from the…

block in the flea’s gut which prevents it from fully digesting and metabolizing its food source. The flea is starving and full at the same time and as it sucks the blood from its victim it is also regurgitating contaminated blood back up and into the dermis of the victim. The bacteria is then drained via interstitial fluid into the nearby lymph node. Another way for the bacteria to be transmitted is through contact with an infected rodents blood or tissue such as might happen when hunting and…

occupied the whole epidermal thickness in 14 cases (40%) and the basal cell layer in 21 cases (60%). Epidermal H score had a mean ± SD value of 113.4±50.8. Epidermal H score category is low in 25 cases (71.4%) and high in 10 cases (28.6%) (Table 2). (b) Dermis: 14 of the examined samples contained dermal adnexa. The dermal adnexal LXR-α expression was positive in all of them. All of them showed cytoplasmic pattern. Dermal localization occupied the whole thickness in 10 cases and the outer root…

Should this particular scenario present itself, an MLT should consult the (SDM) and discuss the appropriate course of action. The MLT will assume consent via the test orders and via communication with the (SDM). The MLT will make sure to involve the patient in the discussion as much as possible. Since the patient is both visually and hearing impaired; verbal and visual conformation are considerably harder to obtain. The (SDM) should have a list of tools and techniques required for that…

Fentanyl can be administrated through transdermal route. Drugs must across many layers of epidermis and dermis before getting into bloodstream, so the absorption rate of Fentanyl is low. However, the bioavailability of Fentanyl by transdermal route is quiet high(80-100%) because no Fentanyl is metabolised by liver before absorption. Fentanyl can also be administred by sublingual route and buccal route. By sublingual route, the rate of absorption is also high because there are many capillaries…

The use of tanning bed associates to almost 76percent of melanoma cases found. Skin is the largest organ of ones body and must be well taken care of. Damage may cause harmful effects to the layers of the skin not only in the epidermis but to the dermis and hypodermis as…

This mutant humanoid was found performing at a carnival freak show with a sign above him, dubbing him “Lobster Man.” He was cognitively normal and appeared normal except for his hands and feet (Basel, Kilpatrick & Tsipouras 2006; and van Silfhout, et al. 2009). The 1st digits were also normal, but on each hand/foot, digits 2 and 3 looked as if were fused together as were digits 4 and 5. Upon further investigation, it was seen that the 2nd, 3rd, and 4th rays weren’t present at all (Gulia & Marwah…
