A&P final unit 5 Flashcards
4 main types of tissue
Connective, epithelial, muscle and nervous
Muscle
Contractile
Thermogenic
Multi-nucleated
Types of muscle tissue
Skeletal
Cardiac
Smooth
Skeletal muscle
Attaches to and moves bones
Striated
Multinucleated and voluntary
Cardiac muscle
Muscle tissue of the heart
striated
involuntary
Smooth muscle
Muscle tissue in vessels and organs
Nonstriated
Appears smooth
Involuntary
Nervous tissue
Communication among body systems
* Coordination of systemic activities
* Brain, spinal cord, nerves
Neuron
transmit signals
dendrites, axons and cell bodies
neuroglia
support and protect neurons
Epithelial tissue
Coverings, linings and glands
Cells packed tightly
Reproduce rapidly
Avascular
Apical surface and basement membrane
Functions of epithelial tissues
Protection
Absorption
Filtration
Secretion
Classifications of epithelial tissue
Squamous
Cuboidal
Columnar
Transitional
Layers of epi tissue
simple, stratified, psuedostrat
Simple squamous
One layer, flat, thin barrier
Allows rapid movement of molecules across membrane
Simple cuboidal
One layer
cube shaped
secretion
mostly glandular
simple columnar
one layer
tall and narrow for absorption
can be ciliated (respiratory) or non-ciliated (digestive)
Pseudostratified Columnar Epithelium
One layer but looks like more
Large passageways of respiratory tract
Keratinized Stratified Squamous Epithelium
skin
Non-Keratinized Stratified Squamous Epithelium
mouth, vagina, throat, anus
