Key Anatomical Features Of The Integumentary System

It is a barrier against the effects of the ultraviolet rays of sunlight. For example the human epidermis undergoes gradual tanning as a result of an increase in melanin.

Talking about skin aging is a sensitive topic these days as no one would like to actually picture the whole process of their skin losing that youthful appeal after a few years. However, it is essential to know that our skin is like any other part of our body. To be more scientific, skin is the largest organ of the human body. This organ is the first layer which serves as the line of defense and prevents the entry of harmful microbes as well as harmful particles. Apart from this, the body temperature is regulated and the moisture content in the body is also regulated to a certain extent by the skin.

Vitiligo is a skin disease that makes white patches of skin appear on different parts of the body it can even turn hair white . This happens because the cells that make our skin the colour it is (melanin) are destroyed in certain areas, then the cells are called Melanocytes. This disease also only affects 1%of the population.

The purpose of the experiment was to understand how strong a bessbug by using weights and observing the time the best bug takes to travel to a certain distance.

Spongy bone also knowns as cancellous contain red and yeallow bone marrow. Red bone marrow produces roughly 200 million of red blood cells (RBC) per a day. Yellow bone marrow contains primary fat cells. This can be transformed into red bone marrow to provide RBC if needed (Ivy Rose Holistic,n.d). The sponge is light and have low density which balance the heavier parts of bone. Sponge tend to form a long line of stress which gives strength and flexibility in that area (Biology dictionary, n.d). articular cartilage is smooth elastic tissue which decreases friction and distribute load. Cartilage exhibits stress-shielding of the solid matrix components due to its high-water content, the incompressibility of water and the structural organization of the proteoglycan and collagen molecules (Derek Moore,n.d). Epiphyseal line is area of developing tissue and everyone has at least two, one at each end of bonePeriosteum is outer membrane which contains connective tissue, nerves and capillaries. It allows blood in and out of bone and help with growth and repair (PubMedhealth,n.d). compact bone provides the strength and protection of bones. It provides strong mechanical layers which with

The reflex process begins when the tack, or stimulus, makes contact with 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 contains Meissner’s corpuscles, touch receptors that are sensitive to light touch, which would be able to sense the feeling of the tack making contact with the epidermis. Within the reticular layer are Pacinian corpuscles, touch receptors that can detect deep pressure and vibration, such as the pressure of the tack against the foot. However, when the mechanical pressure of the tack against the tissue of the foot becomes so strong that it causes damage, pain receptors known as nociceptors take over. Once the tack

Tropomyosin is a long strand. It loops around the actin chains in the thin filament. It covers the myosin binding site of the actin and tropomyosin molecules and prevents muscle

Chapter six welcomes us into the skeletal system by presenting functions,types,structure, and development of bones. We are also presented the ideas of fractures and even the spine- curling snap of a broken bone which means a band aid simply won 't do! For example, Hematoma formation , Fibrocartilaginous callus, Bony callus ,and Remolding must occur to heal ,aka 3-10 weeks in a signature infested cast ,and if the break eventuated* on your arm, a complementary farmer 's tan. The Axial Skeleton makes an appearance by explaining itself as lying in the middle of the body and consisting of the skull, hyoid bone, vertebral column, thoracic cage, and middle ear bones. The complexity, physiology and delicate fashions of each member of this group is expressed. The Appendicular Skeleton compliments the axial for without the appendicular you would be unable to walk or wave "Hi" because you guessed it , it is composed of your appendages or if you will arms and legs. Until this point in

As soon as a paw pad abrasion shows keratinization on the brand new epithelium, it is safe to stop bandaging the wound.

Their disposal tends to be similar to that of normal epidermis: immature/basal cells at the periphery, becoming more mature to the centre of the tumor masses. Tumor cells transform into keratinized squamous cells and form round nodules with concentric, laminated layers, called "cell nests" or "epithelial/keratinous pearls". The surrounding stroma is reduced and contains inflammatory infiltrate . Poorly differentiated squamous carcinomas contain more pleomorphic cells and no keratinization. and squamous-cell carcinoma. There is little evidence that it is effective in preventing basal-cell carcinoma. Other advice to reduce rates of skin cancer includes avoiding sunburning, wearing protective clothing, sunglasses and hats, and attempting to avoid sun exposure or periods of peak exposure. The U.S. Preventive Services Task Force recommends that people between 9 and 25 years of age be advised to avoid ultraviolet

The cells that play an important role in the skin are the keratinocyte and the melanocyte. The keratinocyte is the formation of the keratin layer that protects the skin and the underlying tissues from the environmental damages. Melanocytes are the cells that are involved and responsible for the person's skin and hair color which produce a skin pigment called melanin. One of the functions of the melanin is to protect the skin from the sun damage and Ultraviolet (UV) radiation. Melanocytes cells are commonly found in part of the outer layer of skin, which is known as the epidermis. The color of any individual’s skin is produced by melanin. When skin is being exposed to the sun, melanocytes are producing more melanin, or pigment, causing the skin to gradually darken (Melanoma).

Choose five pathological conditions of the skin or Integumentary system. Describe each condition including symptoms; and cite treatment for each condition.

These regions of the skin that are often scratched turn out to be thick and weathered in appearance, and the patches can be red and darker than whatever is left of the skin. Constant scratching can prompt perpetual changes in skin shading. See a doctor if encountering exceptional tingle and/or there are perceptible changes in the skin. Our skin is the boundary to the outside world, is to some degree waterproof, and keeps our inner organs and frameworks safe from the components and from microorganisms attacking our bodies. Atopic dermatitis patients have impeded hindrance capacity. This implies the skin boundary is separated, loses dampness, and can permit microbes to develop and enter the body. The loss of water leaves the skin dry and broke. The objective of eczema administration is to renew dampness, and make a boundary to ensure the skin. This is the reason creams can offer assistance.

The human skeletal system consists of 206 bones and associative tissue such as joints, cartilage, ligaments, and tendons. Each bone is a complex living organ that is made up of cells, minerals, and protein fibers. When joined together, the skeletal system provides the base framework, giving shape to the unique human body and provides support and protection for the soft tissues that make up the rest of the body. The skeletal system also provides attachments points for muscles enabling movements at the joints. In addition, new red blood cells are produced by the bone marrow inside of our bones. You see, bones act as the "body 's warehouse" by storing or preserving calcium,

The epidermis is the layer of skin that we can see. It varies in thickness. The thickest layer is on the soles of the feet and the palms of the hands. The thinnest layer is on the eyelids and nipples. The cells on the surface are constantly coming off (shedding) this is known as desquamation. They are also constantly being 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:
