Cards

Term
tissues
Definition
groups of cells that are similar in structure and perform a common function
Term
histology
Definition
the study of tissues and how they are arranged into organs
Term
connective tissue, epthelial tissue, muscle tissue, and nervous tissue
Definition
what are the 4 primary tissues?
Term
simple squamos, simple cuboidal, simple columnar, stratified squamos, pseudostratified columnar, and transitional
Definition
what are the different types of epithelial tissue?
Term
-found in air sacs of lungs and linings of blood vessels
-function: smooth lining, reducing friction, and allowing simple diffusion
Definition
where do you find the simple squamos tissue/what are its functions?
Term
-form many major glands and glandular organs, major cell type of kidney and pancreas
-functions= secretion of fluid or hormones (Sweat,oil) and re-absorption (kidneys)
Definition
where do you find simple cuboidal tissue/what are its functions?
Term
-inner portion of digestive tract, uterine tubes, often associated with Goblet cells
-provide absorptive areas on inner portions of digestive tract
goblet cells secrete mucin
Definition
location and function of simple columnar cells?
Term
-lining of the respiratory tract and portions of the male reproductive tract
-protection and secretion
**have cilia
Definition
location and function of pseudostratified columnar?
Term
-urinary bladder, renal pelvis, ureters
-permits expansion and recoil after stretching
Definition
location and function of transitional tissue?
Term
fibrous connective tissue, cartilage, bone, and blood
Definition
types of connective tissue?
Term
loose connective tissue and dense connective tissue
Definition
types of fibrous connective tissue
Term
hyaline cartilage, fibrocartilage, and elastic cartilage
Definition
types of cartilage
Term
reticular, areolar, and adipose
Definition
type of loose connective tissue
Term
dense regular, dense irregular, and elastic
Definition
types of dense connective tissue
Term
-deep in skin, padding around eyes and kidneys
-provides padding and cushions shock; insulates
Definition
location and function of adipose tissue?
Term
-found throughout the body in blood vessels
-transport, immune function
Definition
location and function of blood connective tissue
Term
-between tips of ribs and bones and trachea
-reduces friction between bony surfaces
-cells known as chondrocytes
Definition
location and function of hyaline cartilage
Term
-throughout the body
-support, regulates calcium levels, immune function
-cells known as osteocytes
Definition
location and function of bone
Term
skeletal muscle, cardiac muscle, and smooth muscle
Definition
types of muscle tissue
Term
-cells referred to as muscle fibers
-striated, multinucleated, voluntary
Definition
characteristics of skeletal muscle
Term
-cells referred to as myocytes
-striated, branced, multinucleated, involuntary, intercalated disc
Definition
characteristics of cardiac muscle
Term
-intestines (peristalsis), blood vessels, uterus, urinary tract, most organs
-nonstriated, involuntary
Definition
location and characteristics of smooth muscle
Term
neurons and glial cells or neuroglia
Definition
two cell types found in nervous tissue
Term
neuron
Definition
specialized cell that conducts electrochemical impulses
Term
dendrites, cell body (soma), and the axon
Definition
three main regions of the nervous tissue?
Term
glial cells or neuroglia
Definition
play supportive roles for neurons
Term
epidermis
Definition
outer layer of skin composed of keratinized stratified squamos epithelium
Term
stratum corenum, stratum lucidum, stratum granulosum, stratum spinosum, and stratum basale
Definition
5 layers of epidermis?
Term
dermis
Definition
connective tissue attached to epidermis by a basement membrane that supports the epidermis and connects the epidermis to underlying hypodermis.
Term
papillay layer and reticular layer
Definition
two layers of the dermis?
Term
epidermis
Definition
outer layer of skin composed of keratinized stratified squamos epithelium
Term
papillary layer
Definition
functions in adhesion of dermis to epidermis
Term
reticular layer
Definition
large section of dermis that functions in primary sensory functions of the skin. there are nerve and blood vessels present throughout.
Term
keratin
Definition
makes cells more tough
