Epithelial, Connective, Muscle, and Nervous Tissues Flashcards
simple squamous epithelium (define and give examples)
one layer of flat epithelial cells
allows for exchange of nutrients, gases, and wastes
air sacs of lungs, heart, blood vessel linings
simple cuboidal epithelium (define and give examples)
one layer of cube shaped epithelial cells
functions in absorption and secretion
kidney tubule linings, and glands
simple columnar epithelium (define and give examples)
one layer of tall column shaped epithelial cells
carries out absorption and secretion
gut lining and respiratory tract
pseudostratified columnar epithelium (define and give examples)
one layer (but appears to be multiple) of tall, column shaped epithelial cells
carries out absorption and secretion
stratified squamous epithelium (define and give examples)
multiple layers of flat epithelial cells
protects body against abrasion, infection, and drying out
skin surface, mouth lining, esophagus, vagina
epithelial tissue (define and give examples)
forms boundaries between different environments, protects, secretes, absorbs, filters
skin surface, GI tract lining
transitional epithelium (define and give examples)
lines urinary tract
exocrine modified epithelial tissue (define and give examples)
secrete material outside the body
sweat glands, sebaceous glands, salivary glands
endocrine modified epithelial tissue (define and give examples)
secrete chemicals inside the body
hormones
areolar loose connective tissue (define and give examples)
wraps and cushions organs
under skin, around organs and blood vessels, between muscles
adipose loose connective tissue (define and give examples)
used for insulation and energy storage, can also cushion organs
under skin, around kidneys and heart
reticular loose connective tissue (define and give examples)
used for support and structure
lymph nodes, spleen, tonsils, bone marrow, and liver
regular dense connective tissue (define and give examples)
Can withstand a lot of stress
tendons and ligaments
irregular dense connective tissue (define and give examples)
contains lots of collagenous fibers to give the skin support
dermis layer of skin
elastic dense connective tissue (define and give examples)
provides elasticity and resistance to breaking
within the walls of arteries
dense vs loose connective tissue
loose connective tissue has fewer cells and more ECM while dense connective tissue has more cells and less ECM.
connective tissue (define and give examples)
used as glue or filler for the body
connective tissue has cells spread far out creating a space called the extracellular matrix
hyaline cartilage (define and give examples)
smooth and tough to provide support and allow bones to slide past each other
joints, ribs, nose, larynx, trachea
fibrocartilage (define and give examples)
tough and flexible
intervertebral discs
elastic cartilage (define and give examples)
lightweight and flexible
external ear
cartilage (define)
provides flexible support and cushions
compact bone (define)
dense outer layer of the bone
spongy bone (define)
porous interior layer of the bone
blood (define)
transports nutrients, waste, gases, hormones, and fights infections.
