Keratinized Stratified Squamous Epithelium (White Skin): Vertical Section (Slide 7) List of Tissue: This section shows white skin which is composed of keratinized stratified squamous epithelium. The structures of the white skin includes the keratinized stratified squamous epithelium, merocrine sweat glands, apical (free) surface, basal membrane, sebaceous gland, dense irregular connective tissue, collagen fibers in bundles, a blood vessel, and nuclei of the epithelium. Description of the tissues:
region. Thickest on the soles of the feet and thinnest in the area around the eyes. The epidermis is divided into 4 layers from the bottom are stratum basale, stratum spinosum, stratum granulosum, and stratum corneum. For the hand palms and the foot soles, between stratum corneum and stratum granulosum also has a transparent layer called stratum lucidum. Stratum Basale is the bottom layer of the epidermis, directly adjacent to the
In this discussion post, I'll discuss how the structure of the epidermis and dermis contribute to their functions. I'll also describe all the structures of each and describe how each structure contributes to the function of their respective tissue layer. The epidermis and dermis are tissue layers that make up the skin (integument) covering the body. The layers (strata) of the epidermis range from four to five, depending on where they are on the body; and are classified into two types of skin: thin
The Integumentary system contains the hair, the skin, nerves, nails and glands. There are four types of glands of the Integumentary system. 1.) Sudoriferous glands. 2.) Cerminous glands. 3.) Sebaceous glands. 4.) Mammary glands What are the functions? The Integumentary system protects the body from infections and regulates temperature. It also, protects your body living organs. The integumentary system helps to get rid of waste and sensation plays a big role in this system. It plays as your touch

generally divided into two layers, the epidermis and the dermis. Below the dermis a subcutaneous fat layer is found. The epidermis can be further divided into several sub-layers. These are the stratum corneum, the stratum lucidum, the stratum granulosum, the stratum spinosum, and the stratum germinativum. The stratum germinativum is usually referred to as the basal layer. Skin optics is the manner in which skin reflects and transmits light of different colors, or wavelengths, is determined by the
It is much thicker than the epidermis and contains collagen, reticular and elastic fibers, and is vascular. The area where the dermis meets the epidermis is unique in that the epidermis contains ridges at the stratum basale layer which interlocks with the dermal papillae, which are upward projections, like waves, on the uppermost surface of the dermis. The dermis had two sublayers. The papillary layer is in the dermal papillae and near it and is made up of areolar

are Langerhans cells, melanocytes, Merkel cells and sporadic T-lymphocytes. Epidermis is subdivided into the following strata (beginning with the outermost layer): stratum corneum (SC), stratum granulosum, stratum spinosum (SS) and stratum basale (SB). In the thick skin on the soles of the feet and the palms of the hands, the stratum lucidum (SL) can be found (Murphy, 1997, James et al.,
The Integumentary System is the organ system that act as the protector. It shields the body from many types of harmful things and damages, such as viruses, bacteria, and pollutions. One way of harmful things to enter the body is if the skin was somehow opened by getting cut or torn. Within the Integumentary System there is the skin. The skin is the largest organ of the humans body. It covers more than three thousand square inches of the body and weighs over six pounds. I believe the skin is the most
epidermis, which is the outer layer of the skin, is made up of four to five layers in some parts (Shier, Butler, & Lewis, 2009). In the majority of the areas, just four layers can be differentiated: the stratum basale, stratum spinosum, stratum granulosum, and stratum corneum (p.119). Another layer is the stratum lucidum which can be found in the thicker part of the skin of the palms and ... ... middle of paper ... ...be also highly affected in people with albinism.

The ANS is part of the peripheral nervous system, being split into sympathetic pathways, which prepare the body for action and parasympathetic pathways which prepare the body for rest. This regulates the functions of the body and some of the muscles automatically. Sympathetic pathways change nerve activity during times of stress, exercise, low blood glucose levels, excitement or fear, due to the flight or fight response. These changes can have an effect on homeostasis by increasing heart rate, increasing
Background Acne vulgaris is the most common cutaneous disorder affecting adolescents and young adults. Acne vulgaris is a disease of pilosabaceous follicles with four pathogenic factors. These factors are follicular hyperkeratinization, increased sebum production, infection with Propionibacterium acnes within the follicle, and resulting inflammation. Follicular hyperkeratinization is increased proliferation and decreased desquamation of keratinocytes lining the follicular orifice. This results
