Exam 1 chap 4 & 5 anatomy and physiology

list 3 functions and 3 locations of eptihelial tissues throughout the body

protection, absorption, secretion. epidermis, lining of digestive tract, and lining of blood vessels

list 3 functions and 3 locations of connective tissues throughout the body

supports and binds tissues, protects organs, stores energy. bone, tendons and ligaments, adipose

list 3 functions and 3 locations of muscle tissue

movement, posture, and heat. heart, skeletal muscles, smooth muscle

list 3 functions and locations of nervous tissue

detects stimuli, processes information, and transmits nerve impulses. brain, spinal cord, peripheral nerves

what is the basal surface of epitheal tissue? what does it connect?

it is the bottom surface of epthielial cells. attaches to the basement membrane

which surface (basal or apical) touches the lumen of a blood vessel?

apical surface

can epithelial tissue regenerate and is this of any significance?

yes, it repairs itself quickly after injury because it experiences frequent wear and tear

whats the difference between simple and stratified epithelium

simple is one layer and stratified is multiple

what is the function of cilia? are they on the basal or apical surface

moves mucus or other materials across cell surface. apical

true or false, adipocytes each store many small fat droplets

false

list 2 characteristics of elastin fibers

stretch easily, return to original shape

what is the importance of ground substance in connective tissue

supports and binds cells and fibers

true or false tightly packed collegan fibers compose dense regular connective tissue such as tendons, ligaments, and aponeuroses

true

which type of connective is highly calcified and used to support weight

osseous tissue

what is a major difference betweenmucous and serous membranes

mucous lines passages that open to the outside, serous lines closed body cavities.

true or false, immflamation is a hinderence for healing and tissue repair

false

true or false, the cutaneous membrane is composed of the outer epidermis and the inner dermis

true

true or false, the subcutaneous layer us part of the epidermis

false

list 3 functions of the integumentary system

protection, regulation of temperature, sensation

what tissue type dominates the epidermis

keratinized stratified sqamous epithelium

true or false, the epidermis is vascularized

false

list the five strata of thick skin from most superficial the deepest

corneum, lucidum, granulosum, spinosum, basale

stem cells that replace superficial keratinocytes are found in which layer

basale

what is the difference between insensible and sensible perspiration

insensible has water evaportating without noticing and sensible is like sweat

true or false, a cut made perpendicular to tension lines remians shut and heals well

false

list two things that nerve fibers in the skin influence

sensory perception and control of sweat glands and blood vessels

what two pigments influence skin color and where are they found

melanin in epidermis and carotene in adipose

what parts of the body do hairs not cover

palms and soles, lips, nipples, portions of genitalia

what are the functions of hair

protection, insulation, sensation

what functions do sebaceous glands produce

secrete sebum, prevent dryness, lubrication

what are the four phases of injury repair to the integumentary system

inflammatory, migratory, proliferative, remodeling

in which layer of the integumentary system do the accessory structures originate

the dermis
