The Integument system will move against mechanical loads such as friction and vibrations that can detect physical changes in the outside environment, with unpleasant and avoidable stimuli from internal organs as vital functions in the body. Recall that sweat glands, accessory structures to the skin, secrete water, salt, and other substances to cool the body when it becomes warm. As a function of excretion is to secrete sweat, oil and salt. Match. (credit: “Wbensmith”/Wikimedia Commons). Hair is composed of roots that are cells without keratin and stems consisting of keratin cells. The dermis, which is responsible for the elasticity and resilience of the skin, exhibits a reduced ability to regenerate, which leads to slower wound healing.

The integumentary system consists of the skin, hair, nails, glands, and nerves. The integumentary system helps regulate body temperature through its tight association with the sympathetic nervous system, the division of the nervous system involved in our fight-or-flight responses. The Sebaceous gland serves to control the secretion of oil into the space between the hair follicles and the hair stem that will lubricate the hair so that it becomes smooth, supple and soft. When body temperatures drop, the arterioles constrict to minimize heat loss, particularly in the ends of the digits and tip of the nose.

For any form of armor, a breach in the protective barrier poses a danger. Vitamin D is essential for normal absorption of calcium and phosphorous, which are required for healthy bones. The sympathetic nervous system is continuously monitoring body temperature and initiating appropriate motor responses. You might think of a Roman centurion or a medieval knight in a suit of armor. The skin acts as a sense organ because the epidermis, dermis, and the hypodermis contain specialized sensory nerve structures that detect touch, surface temperature, and pain. Meanwhile, sweat glands (sudorifera) serve to secrete sweat when body temperature increases. Hair is found all over the skin except the soles of the feet and the dorsal part of the distal phalanges of the fingers, feet, pe**nis, labia minora and lips. MarketHealthBeauty specialized in Health Beauty Product Reviews, Health Beauty Tips, as well as promotional items to consumer, distributor and wholesaler. The integumentary system functions in thermoregulation—the ability of an organism to keep its body temperature within certain boundaries—even when the surrounding temperature is very different.

The integumentary system is everything covering the outside of an animal's body. In this micrograph of a skin cross-section, you can see a Meissner corpuscle (arrow), a type of touch receptor located in a dermal papilla adjacent to the basement membrane and stratum basale of the overlying epidermis. The hair root plexus surrounding the base of the hair follicle senses a disturbance, and then transmits the information to the central nervous system (brain and spinal cord), which can then respond by activating the skeletal muscles of your eyes to see the ant and the skeletal muscles of the body to act against the ant. Specifically, you will learn about: The functions of the organs of the integumentary system - the skin, hair, and nails - including protecting the body, helping to regulate homeostasis, and sensing and interacting with the external world.

5. Because the needles involved in producing body art and piercings must penetrate the skin, there are dangers associated with the practice. Among these changes are reductions in cell division, metabolic activity, blood circulation, hormonal levels, and muscle strength (Figure 3). Merkel cells, seen scattered in the stratum basale, are also touch receptors. The integumentary system helps regulate body temperature through its tight association with the sympathetic nervous system, the division of the nervous system involved in our fight-or-flight responses. Flashcards. Acts as a receptor for touch, pressure, pain, heat, and cold 7. Protection – The most important function of this system is to protect our body against harmful external agents. Additionally, invasive techniques include collagen injections to plump the tissue and injections of BOTOX® (the name brand of the botulinum neurotoxin) that paralyze the muscles that crease the skin and cause wrinkling. The functions of the integument system include: Here are some examples of integumentary systems, including: Structurally, the skin is divided into 3 main layers, namely: It is the bottom layer of the epidermis and consists of connective tissue. It primarily consists of the skin, nails, hair, and glands. Figure 1. • MILAGROS DE LOS SANTOS. Only $2.99/month. A person with tattoos should be cautious when having a magnetic resonance imaging (MRI) scan because an MRI machine uses powerful magnets to create images of the soft tissues of the body, which could react with the metals contained in the tattoo dyes. The skin and accessory structures perform a variety of essential functions, such as protecting the body from invasion by microorganisms, chemicals, and other environmental factors; preventing dehydration; acting as a sensory organ; modulating body temperature and electrolyte balance; and synthesizing vitamin D. The underlying hypodermis has important roles in storing fats, forming a “cushion” over underlying structures, and providing insulation from cold temperatures. This reduced circulation can result in the skin taking on a whitish hue. Recent studies are also finding a link between insufficient vitamin D and cancer. Choose from 500 different sets of functions 5 integumentary system flashcards on Quizlet. The Integumentary System is a process of cell formation with continuous exchange or change as part of the human cell component that involves the role of living beings for human life. It protects our deeper tissues and organs from infections by fighting harmful bacteria & germs. Wrinkling of the skin occurs due to breakdown of its structure, which results from decreased collagen and elastin production in the dermis, weakening of muscles lying under the skin, and the inability of the skin to retain adequate moisture. The skin assists in homeostasis (keeping differ… Other cells in the skin, such as melanocytes and dendritic cells, also become less active, leading to a paler skin tone and lowered immunity.
