Characteristics of Epithelial Tissues (different from others)
spars
polarity- membranes always have one free surface
specialized contacts- cells fit closed together and are bound by
specialized junctions
supported by connective tissue- cells are attached and supported by
basal body membrane
Avascular but inverted- are supplied by nerves but have no blood
supply of their own
regeneration- can easily divide to regenerate the tissue
Epithelia consists of one layer of cells attached to the basement membrane.
Simple
Epithelial consist of two or more layers of cells.
Stratified
Covering and Lining Epithelial are classified by TWO things:
arrangement OR number of layers and cell shape
Based on Cell Shape: Epithelial are classified into THREE categories
scc
squamous (scalelike)
cuboidal (cubelike)
columnar (column-shaped)
An acellular material secreted party by the epithelial cells (basal
lamina) and connective tissue cells (reticular lamina) that lie next
to each other
Basement Membrane
Simple epithelium (one layer of cells) that gives the false
appearance of being stratified
Pseudostratified Epithelium
SIX Epithelial Cells that provide PROTECTION

FIVE Epithelial that provide SECRETION

Outward messengers (Nervous Tissue)
Motor Neurons
Inner messengers (Nervous Tissue)
Sensory Neurons
Nervous Tissue is made up of TWO major cell population
neuroglia
neurons
Cells talk to each other through these (Nervous Tissue)
Axon
Afferent means (Sensory Neuron)
Toward
Efferent means (Motor Neuron)
Away
Special supporting cells that protect, support, and insulate the more
delicate neurons
Neuroglia
Highly specialized to receive stimuli and to generate electrical
signals that may be sent to all the parts of the body (conductivity)
