It can be split into the papillary and reticular layers. indicates ways in which this system affects other systems indicates ways in which other systems affect this one. Adipose tissue consists primarily of cells called adipocytes that are capable of storing fat droplets. It has a variety of additional functions; it may serve to waterproof, and protect the deeper tissues, excrete wastes, and regulate body temperature, and is the attachment site for sensory receptors to detect pain, sensation, pressure, and temperature. Lubrication. In animals and plants, an integument is any natural outer covering, such as skin, shell, membrane, or husk. This process is called keratinization and takes place within about 30 days. We grow old by deserting our ideals. STUDY. ThoughtCo. The most obvious function of the integumentary system is the protection that the skin gives to underlying tissues. Layers of Skin. The sympathetic nervous system is continuously monitoring body temperature and initiating appropriate motor responses. Hair. Antibacterial and antifungal roles. Hair follicles originate in the epidermis and have many different parts. Skeletal System Contains organs and glands that are vital to protecting the body and regulating temperature. The integumentary system is everyone’s first line of defense. The basic components of the mammary gland are the alveoli (hollow cavities, a few millimetres large) lined with milk-secreting epithelial cells and surrounded by myoepithelial cells. By using ThoughtCo, you accept our. The fingernail root produces most of the volume of the nail and the nail bed. Nail Bed The nail bed is part of the nail matrix called the sterile matrix. Did you have an idea for improving this content? Check out our video library. The integumentary system is the body's first line of defense against bacteria, viruses, and other pathogens. give skin pigmentation and protects from UV rays. Protects and covers the body Regulates body temperature Includes organs such as: skin and nerve receptors Has three layers: epidermis, dermis, … At the time of birth, the baby has lactiferous ducts but no alveoli. While studies conducted up until the 1960s found little evidence supporting an antibacterial role for cerumen, more recent studies have found that cerumen provides some bactericidal protection against some strains of bacteria. Emotional stress increases the production of sweat from the apocrine glands, or more precisely: the sweat already present in the tubule is squeezed out. Terminal hair, the fully developed hair, which is generally longer, coarser, thicker, and darker than vellus hair, and often is found in regions such as the axillary, male beard, and pubic. The suckling of the baby causes the release of the hormone oxytocin which stimulates contraction of the myoepithelial cells. The cerumen in the canal is also carried outwards, taking with it any dirt, dust, and particulate matter that may have gathered in the canal. The integument as anorgan, and is an alternative name forskin. It serves as a protective plate and enhances sensation of the fingertip. As the interface with the surroundings, it plays the most important role in protecting against pathogens. Epidermis and dermis. Earwax is partly sebum, as is mucopurulent discharge, the dry substance accumulating in the corners of the eye after sleeping. Heat regulation: The skin contains a blood supply far greater than its requirements which allows precise control of energy loss by radiation, convection and conduction. As a system it has contributions from all embryonic layers. Authors. The integumentary system includes hair, scales, feathers, hooves, and nails. The papillary layer is outermost and extends into the epidermis to supply it with vessels. Mammary glands are the organs that, in the female mammal, produce milk for the sustenance of the young. Below these layers lies the hypodermis or subcutaneous adipose layer, which is not usually classified as a layer of skin. All body systems work in an interconnected manner to maintain the internal conditions essential to the function of the body. The human integumentary system is made up of your skin, nails, hair and some glands. Skin is composed of two main layers, the epidermis and dermis. The reticular layer is more dense and is continuous with the hypodermis. dermis . Bathe every day and wash your hands regularly. Specialties. The epidermis can be further subdivided into the following strata (beginning with the outermost layer): corneum, lucidum, granulosum, spinosum, basale. The concentration of sodium varies from 35–65 mmol/l and is lower in people acclimatised to a hot environment.

Integumentary system works with the excretory system

answer explanation . These cells constantly divide to produce new cells that are pushed upward to the layers above. This portion of the nail is actually beneath the skin behind the fingernail and extends several millimeters into the finger. Also found in the basal layer of the skin are touch receptor cells called Merkel cells. Start studying Chapter 6 - The integumentary system. The sweat glands are controlled by sympathetic cholinergic nerves which are controlled by a center in the hypothalamus. The skin is composed of two main layers: the epidermis, made of closely packed epithelial cells, and the dermis, made of dense, irregular connective tissue that houses blood vessels, hair follicles, sweat glands, and other structures. The Integumentary System What does it do? It also contains DNA repair enzymes which reverse UV damage, and people who lack the genes for these enzymes suffer high rates of skin cancer.
