Anatomy chapter 5
| Question | Answer |
|---|---|
| The outer layer of the skin is the | epidermis |
| The inner layer of the skin is the | dermis |
| The outer layer of the skin is the epidermis which is made of | stratified squamous epithelial tissue |
| The inner layer of the skin is the which is dermis made of | fibrous connective tissue |
| The layer of the skin that is made of stratified squamous epithelium is the | epidermis |
| The layer of the skin that is made of fibrous connective tissue is the | dermis |
| The dermis is made primarily of the proteins | collagen and elastin |
| The new cells of the epidermis produce the protein | keratin |
| The cells of the epidermis produce antimicrobial chemicals called | defensins |
| The cells of the epidermis that phagocytize pathogens are the | Langerhans cells |
| The cells in the epidermis that carry ingested pathogens to lymph nodes are the | Langerhans cells |
| The outermost layer of the epidermis is the | stratum corneum |
| Living skin cells are protected from exposure to ultraviolet rays by | melanin |
| Human hair helps keep dust out of the | eyes; nasal passages |
| Human hair has an insulating function for the | head |
| The living part of a hair is the | root |
| The shaft of a hair is made of | keratin; dead cells |
| The ends of fingers and toes are protected from mechanical injury by | nails |
| The living part of a nail is the | root |
| A nail grows by the process of | mitosis |
| The visible portion of a nail is made of | keratin |
| Scratching an itch is efficient with the use of | fingernails |
| Information about the environment outside the skin is provided by | receptors |
| For the cutaneous senses of pain and heat, the receptors are | free nerve endings |
| For the cutaneous receptors of touch and pressure, the receptors are | encapsulated nerve endings |
| Most cutaneous receptors are found in the | dermis of the skin |
| Drying of the skin is prevented by | sebum |
| The glands that secrete sebum are called | sebaceous glands |
| Sweating promotes heat loss by means of the process of | evaporation |
| In a cold environment, the arterioles in the dermis will | constrict |
| The arterioles in the dermis will constrict when the external environment becomes | cold |
| When the arterioles in the dermis constrict, the loss of body heat will be | decreased |
| In a warm environment, the arterioles in the dermis will | dilate |
| The arterioles in the dermis will dilate when the external environment becomes | warm |
| When the arterioles in the dermis dilate, the loss of body heat will be | increased |
| The precursor molecule for vitamin D is | cholesterol |
| The subcutaneous tissue layer is also called the | superficial fascia |
| Between the dermis and the muscles is the | subcutaneous tissue; superficial fascia |
| In the superficial fascia, the tissue that stores potential energy is | adipose tissue |
| In the superficial fascia, the tissue that contains many white blood cells is | areolar connective tissue |
| In the integumentary system, areolar connective tissue is part of the | subcutaneous tissue; superficial fascia |
| The layer of the integumentary system that cushions some bones is the | subcutaneous tissue |
| The layer of the integumentary system that provides some insulation from cold is the | subcutaneous tissue |
| The layer of the integumentary system that stores potential energy is the | subcutaneous tissue |
| whats missing? arterirs->arterioles->_______->venules->veins | capillaries |
| the subcutaneous tissue stores | fat |
| where is the skin the thickest | palms and soles |
| the basal of the skin is what | the base,the lowest part |
| what happens to cells as they get farther away from capillaries | they die |
| how do you increase melanin | UV light |
| what dose collagen and elastin do to skin | make it strong and elastic |
| True or false do cutting hair make it grow faster | false |
| what dose the pilomotor muscle do | make hair stand uo |
| how is the pilomotor muscle stimulated | cold and emotion |
| True or false cells die to become nails | True |
| what are the the 3 types of glands | sebaceous,ceruminous and sweat |
| what does sebaceous glands secrete | sebum |
| The dermis is made primarily of the proteins | collagen and elastin |
| The lowest layer of the epidermis is the stratum germinativum, and its function is | mitosis |
| In the epidermis, new cells are produced by the process of | mitosis |
| what type of molecule helps make the skin relatively waterproof | protein |
| Langerhans cells are found in the | epidermis of the skin |
| The stratum corneum is made of several layers of | dead cells |
| The stratum corneum is made of several layers of dead cells which in turn are made of | keratin |
| Prevention of water loss or entry is a function of the stratum | corneum |
| Prevention of the entry of pathogens is a function of the stratum | corneum |
| If intact, the stratum corneum is a very good barrier to | pathogens and water |
| Melanocytes produce the protein | melanin |
| Ultraviolet rays stimulate the production of melanin by cells called | melanocytes |
| The sebum secreted by the what inhibits the growth of bacteria on the skin. | sebaceous glands |
| The cerumen secreted by the what prevents drying of the eardrum | ceruminous glands |
| what happens during hot weather to make sweat glands increase their secretion | eccrine |
| The purpose of sweating is to increase the loss of | heat |
| The purpose of sweating is to increase the loss of heat but it has the disadvantage of leading to | dehydration |
| when The skin is charred and may not be painful at first what degree burn is that | Third degree |
| when the skin is painful but not blistered what degree burn is that | first degree |
| when the skin is painful and blistered | second degree |
| name the secretion that prevents drying of the eardrum | cerumen |
| name the secretion that prevents drying of the skin and hair | sebum |
| what is the function of melanin | protects living skin cells from exposure to UV rays |
| what maintains normal body temperature | eccrine |
| producced in follicales in the scalp | hair |
| what tissue connects the skin to the muscles | Subcutaneous |
| what detect changes in the environment | receptors |
| what produces melanin | melanocyte |
| in cold weather the arterioles in the dermis will | constrict to conserve heat |
| In the dermis the receptors for pain are | free nerve endings |
| The adipose tissue contains cells that are specialized to store | fat |
| what are two functions of subcutaneous fat | histamine and inflammation |
| what is the proteins that gives the dermis elasticity | elastin fibers |
| The cells that produce collagen and elastin | Fibroblasts |
| produce a lipid substance called sebum | sebaceous glands |
| the protein that gives the dermis its strength | collagen fibers |
| extensive third degree burns may be serious because of the loss of which layer of the epidermis | stratum corneum |
| In a warm environment the arterioles in the dermis will | dilate |
| Name the two types of connective tissue in the subcutaneous layer | areolar connective tissue and adipose tissue |
| the subcutaneous yissue is located between the | dermis and the muscles |
| what is the other name for subcutaneous tissue is the | superficial fascia |
| where are merkel cells are found in | statum |
