Section 1

Question Answer
Integumentary System: Functionthe skin 1)protecting2) temperature regulation, 3) houses sensory receptors 4) secretes important fluids
Organs of the integumentary systemskin, nails, hair, sebaceous glands, sweat glands
The skin and accessory organs have 2 types of membrane:integument and cutaneous
Primary function of the skin is protection, keeping _______ & _______ _______ from entering the bodypathogens , harmful chemicals
Other protective functions of the skin:stops critical body fluids from leaving the body 2)prevents injury to internal organs
sensory receptors (in the skin) detect:temperature, pain, touch and pressure
Two types of ways fluids are produced in the skin:1) sweat glands - for maintaining internal temp 2)sebaceous glands - produces oily substance that lubricates the skin
Other ways of the skins temperature regulation:1) dialting superficial blood vessels (cooling) 2) constricts superficial blood vessels (heat conserve) 3) fat in the subcutaneous layer acts as insulation
The skin is composed of two layers:superficial epidermis and deeper dermis
One other layer that is not skin is ________ or ____________ layer which assists the functions of the skin.hypodermis or subcutaneous layer

Section 2

Question Answer
Five parts to the epidermis:1) basal layer 20 keratin 3) melanin 4) melanocytes 5) stratified squamous epithelium
What is the composition of stratified squamous epithelium?epithelial tissue consists of flat scale-like cells arranged in overlapping layers or strata; NO Blood suply
Deepest layer of the epidermis is called the basal layer where cells _____ & ______ then are pushed upward toward the ____ layer.grow and multiply, outer
basal cells that are pushed outward, ______ & ________ becoming filled with a hard protein called _____________.shrink & die, keratin
basal layer also contains ____________ (special cells) which produce black pigment called _________. melanocytes, melanin

The epidermis replaces itself every ___ days.25
The dermis is also know as the _______ and is the ______ layer of the skincorium, middle
The dermis is composed of ________ and _________ ______ which are made of strong fibrous ______ that provide strength.connective tissue, collagen fibers, protein
The subcutaneous layer of ________, is a continuous layer of ____ the separates the ______ from deeper layers.fat, dermis
Subcutaneous layer is composed of fat cells called ______ that have what functions?lipocytes; protection, insulation, source of energy

Section 3

Question Answer
Accessory organs located in the skin within the dermis are what five structures:hair, nails, sebaceous glands, and sweat glands
The hair is composed of what parts?arrector pili, hair root, hair follicle, hair shaft
Fibers that make up hair are composed of:protein keratin
The deeper cells in the hair root for older ________ cells to move upward to form the ______ _____.keratinized, hair shaft
The hair shaft grows toward the skin surface with the ______ follicle
________ gives hair its color.melanin
Each hair has a small slip of smooth _______ attached to it called the ______ _____ which causes the hair shaft to ______ ___ when it contracts.muscle, arrector pili, stand up
Nails are a flat plate of ______ called the _____ ____keratin, nail body
The nail body is connected to the tissue underneath by the ____ ____.nail bed
Nails grow longer from the _______ _____ and are protected by the soft tissue _____.nail root, cuticle
The ______ _____ is the exposed edge that is trimmed when nails become too longfree edge
The light-colored half-moon area at the base of the nail is the ___lunula

Section 4

Question Answer
Sebaceous glands (in the dermis) secrete the oil _____ which ______ the hair and skin to keep it from drying out.sebum, lubricates
Sweat glands are also calledsudoriferious glands
sweat glands (highly coiled) travels to the surface of the skin in a ____ ____ that has an opening called a _____ ____.sweat duct, sweat pore
Sweat or perspiration usually are odorless and colorless but when found in the pubic or underarm areas are called ___ _____ that secrete a thicker sweat that produces an oder when it comes in contact with bacteria on your skinapocrine glands
