Stratum corneum 2. Stratum lucidum 3. Stratum granulosum 4. Stratum spinosum 5. Stratum basale Stratum corneum Stratum corneum also called as horny layer is the outer most layer and it mainly consists of dead cells called corneocytes. These corneocytes under pressure lose their nucleus and become dead cells. Due to keratin, a fibrous protein the cytoplasm is usually flattened in nature. These cells also contain phospholipids and glycogen as their components. Stratum Lucidum Stratum lucidum

have, at most, five stratums (layers) of skin in the epidermis. The layer that can be seen is the stratum corneum which is made up of

not receive or give blood, but it has up to five strata. They are the stratum basale, spinosum granulosum, lucidum, and corneum. Multiple epidermises deliver keratin and the protein allows the epidermis to become a muscular protective coating for the skin.   o Stratum basale- These cells are the deepest coating of the epidermis because it is near the dermis. The cells are also attached to the dermis. o Stratum spinosum and stratum granulosum - Both layers are filled with keratin. When the cells leave

extremely thin due to her condition, which means that one specific layer, known as the stratum lucidum will be absent. The layer stratum lucidum is only present in thick skin. The four layers of Stephanie’s epidermis that are affected are known as the stratum basale, stratum spinosum, stratum granulosum, and stratum corneum. In case you are unaware of the importance of these layers of skin, let me inform you. The stratum basale is known as the deepest layer of the epidermis, which allows it to be attached

Stratum Lucidum III. Stratum Granulosum IV. Stratum Spinosum V. Stratum Basale 1.2.2. Dermis It is middle layer which contain connective tissue, sweat gland, hair follicles, collagen, blood vessels, nerves and various glands. Function of dermis layer is to provide strength, elasticity

It is a group of similar cells that have the same functions in human body. Tissues outcomes in the formation of organs made primarily of tissues. (Cinnamon L. , 2) The epithelial tissue’s function is to secret substance, prevent, cover and line ultimately all of the body’s cavities and surface. (Cinnamon L. , 71, 72) Connective tissue is known to bind, support, and separate other organs and tissues. There are five kinds of connective tissue which are cartilage, bone, blood and loose and dense connective

the integument on the bottom of the foot; this is the arrival of a stimulus. The stimulus’ pathway starts at the epidermis, where it will penetrate all five layers, from the outermost stratum corneum, it travels through the stratum lucidum, stratum granulosum, and stratum spinosum, all the way to the innermost stratum basale. From there, it will continue into the dermis, where there is an extensive network of nerve endings and nerve fibers throughout the two layers of the dermis. The papillary layer

replaced from below as cells from the basal layer of the epidermis multiply and are pushed up to the surface. The basal layer of the epidermis receives its blood supply, nutrients and fluids from the dermis. There are five layers of the epidermis: Stratum Corneum (surface): •

: Skin protects the body from ultraviolet rays of sunlight. Exposure to sunlight or to any other source of ultraviolet rays increases the production of melanin pigment in skin. Melanin absorbs ultraviolet rays. At the same time, the thickness of stratum corneum increases. This layer of epidermis also absorbs the ultraviolet rays . 2. Sensory function:-Skin is considered as the largest sense organ in the body. It has many nerve endings, which form the specialized cutaneous receptors). These receptors

Skin is the largest organ of the human body. Skin is part of the integumentary system, the physiological functions include protection with chemical, physical and biological barriers, aids in homeostasis regulation, sense receptors, maintenance, blood storage, as well as excretion by means of sweat. The anatomical structure of the skin can be divided into two main parts, the epidermis and dermis. The third part of the epidermis is the hypodermis, it is also known as the superficial fascia, where it

partitioning and diffusion step. In this route drug passes through cytoplasm of cells. This route is suitable for hydrophilic drugs and highly hydrated keratin gives aqueous pathway to the hydrophilic drugs. The drug passes through the corneocytes of stratum corneum. iii) Intercellular route :- Intercellular pathway the drug diffuses through the continuous lipid matrix present between the cells. The barrier of this route is due tortuous structure formed by corneocytes and the drug has to pass through

1.3. Oral mucosa 1.3.1. Anatomy and histology The oral mucosa is the mucous membrane lining the inside of the mouth and consists of stratified squamous epithelium termed oral epithelium and an underlying connective tissue termed lamina propria (Nanci and Elsevier, 2013). At the lips the oral mucosa is continuous with the skin, and at pharynx the oral mucosa is continuous with the moist mucosa lining the rest of the gut. thus the oral mucosa is

The skin is the largest organ of the body, covering about 1.7 m2 and comprising approximately 10% of the total body mass of an average human being. The primary function of the skin is to provide a barrier between the body and the external environment. This barrier protects against a range of noxious assaults like UV radiation, mechanical, chemical and biological insults like allergens and microorganisms. Its physical strength and elasticity provide optimal mechanical support; semi-permeability to
