Integumentary system ANSWERV V Made up of skin and it's appendage integumentary system functions ANSWERV ¥ protects against environmental hazards, helps regulate body temperature, provides sensory information How much does skin weigh a. Slbs b. 10lbs c. 6lbs d. 4lbs ANSWERVV How many layers of skin do we have? a2 b.3 cl d.4 ANSWERVV a Name the layers of the skin ANSWERY ¥ epidermis and dermis Epidermis layers ANSWERV ¥ Is a layer of epithelial tissue that can be divided into sub categories. It is found on top of the Dermis Dermis layers ANSWER¥ ¥V Layer of dense connective tissue that connects the skin to tissue below it. Beneath the dermis is a subcutaneous layer sometimes call the hypodermis. Desmosomes ANSWERY ¥ interlocking cellular bridges that hold skin cells together. These are responsible for the unique flexibility, entirety, and whole continuous structure of the skin Epidermis ANSWERV ¥ is composed of keratinized, stratified squamous epithelium. It is made of four or five layers of epithelial cells, depending on its location in the body. It does not have any blood vessels within it (i-c., it is avascular). Keratinization ANSWERV ¥ a process by which epidermal cells of the skin change shape, composition and lose water as they move to the upper layers and become mainly protein and die Karatin ANSWERV ¥ A protein that is the main component of the skin; the main substance of the hair, skin and nails Strata ANSWERV V The process of keratinization produces distinct layers of the epidermis is called stratum corneum ANSWERY ¥ outermost layer of the epidermis, which consists of flattened, keratinized cells. Commonly called the horny or leathery layer. Yes cells move up from the basement membrane, they eventually ANSWERV V Die The protein material of hair and nails is ANSWERV ¥ keratin There are Layers of epidermis ANSWERV V Five Dead cells converted to protein make up the ANSWERY ¥ Stratum corneum A callus on the foot is called an ANSWERV ¥ Corn Cells Lose their nuclei and become compact and brittle in the ANSWERV ¥ Stratum granulosum The stratum Spinosum contains cells that are in structure ANSWERVJ Polyhedron Cells of the epidermis are capable of dividing are found in the - ANSWERYV ¥ stratum germinative Those cells responsible for skin colour are ANS WERV V Melanocytes Ratio variation in certain colour is determined by ANSWERV J Melanin And absent of melanin produced as a condition called ANSWERV ¥ Albinism True skin is the ANSWERV V Dermis A specialist concern with implemtoryory responses of the skin and reactions of the immune system is ANSWERV ¥ Allergist Besides memory glans Is a main characteristic of mammals ANS WERV V Hair blueish tinge to the skin colour is called ANSWERV V Cyanosis Goosebumps are caused by What muscle ANSWERY ¥ arreetor pili Hair growth begins in the ANSWERV ¥ hair bulb Hey nail will grow from the ANSWERV V Nail bed The Eponychium is: ANSWERV V cuticle What is the oily substance responsible for lubrication of the skin ANSWERV ¥ Scbum What gland is Sebum excreted from ANSWERV V Sebaceous gland The dermis is also known as the ANSWERV Vv corium Skin modifications ANSWERV V appendages epidermal cellular links ANS WERV V desmosomes clear layer ANSWERV ¥ stratum lucidum varies skin pigmentation ANSWERV V melanin Affected by first degree burns ANS WERY V epidermis subcutancous layer ANS WERV V hypodermis hair's principal portion ANSWERV ¥ cortex Harris visible portion ANSWERV ¥ Shaft hair texture ANSWERV ¥ Keratin Visible nail ANSWERV V nail body oily gland ANSWERV V sebaceous Salty liquid secretion ANSWERV V Sweat Skin function ANSWERV ¥ -thermoregulation sensation -metabolism of vitamin D -protection from shear -protection from water loss Skin cancer ANSWERV ¥ melanoma Human Papillomavirus (HPV) ANSWERV ¥ warts, 1.
