Tissues Flashcards
what are the four basic tissues of the human body?
epithelial tissue
connective tissue
muscle tissue
nervous tissue
what are the three types of epithelial tissue?
squamous
cuboidal
columnar
what are the four different arrangements of epithelial tissue?
simple
stratified
pseudostratified
transitional
are pseudostratified and stratified different?
yes- “pseudo” means false so it’s not actually stratified but it LOOKS like it is. All of the cells touch the basement membrane which makes it not stratified.
simple squamous epithelium- appearance, where it’s found, function
single layer of flat cells
alveoli in lungs
absorption
stratified squamous epithelium- appearance, where it’s found, function
stacked flat cells
skin, mouth, throat
protection
simple cuboidal epithelium- appearance, where it’s found, function
square-ish
walls of kidney
absorption
simple columnar epithelium- appearance, where it’s found, function
columns
disgestive system, reproductive organs
secretion, absorption
pseudostratified columnar epithelium
looks like it’s stratified but it’s not
nasal cavity, trachea
cilia and mucous secretions help collect foreign materials so you can cough or sneeze them out
transitional epithelium- appearance, where it’s found, function
differing shapes allow cells to stretch but don’t absorb
lines urinary bladder, ureters, urethra
undergo a change in their shape and structure to prevent absorption
what are the four main types of connective tissue?
connective tissue proper
cartilage
bone
blood
what are five major functions of connective tissue?
binding and supporting protecting insulating storing reserve fuel transporting substances (blood)
what are six major functions of epithelial tissue?
Protection Sensory reception Secretion Absorption Filtration Excretion
what are three major functions of muscle tissue?
provides posture and body support
locomotion
heat production
what are three major functions of nervous tissue?
controls the body’s movements
sends and carries signals to and from the different parts of the body
has a role in controlling bodily functions such as digestion
