serous membranes - CORRECT ANSWER--serous membranes
-A duals membrane lining that "covers organs" and "lines the cavity wall".
Produce
"serous fluid",

parietal layer. - CORRECT ANSWER-layer that lines the internal body
wall/cavity=

visceral/viscera - CORRECT ANSWER-lines the organs

Serous Membranes of Lungs? - CORRECT ANSWER-Visceral Pleura

Serous membrane lining rib cage? - CORRECT ANSWER-Partiera Pleura

Tissues - CORRECT ANSWER-collection of cells functioning together providing
an overall collective function

Muscular tissue - CORRECT ANSWER--Tissues for contraction ( body
movemen)

-Molecules that interact to generate movement? - CORRECT ANSWER--Actin
and myosin (cytoskeleton proteins)

Neural (nervous) Tissue - CORRECT ANSWER--Sends fast, electrical impulses
or signals
-Rapidly senses internal or external environment
-Processes sensory information and controls responses

*Neurons - CORRECT ANSWER-conduct electrical impulses for quick
communication

-Neuroglial - CORRECT ANSWER-supporting cells that maintain composition of
neural fluid;

,Cell body (neuron) - CORRECT ANSWER-houses? Nucleus, nucleolus,
organelles

Dendrites, - CORRECT ANSWER-short branches extending from the cell body,
that function to? Receive incoming signals;

Axon (nerve fiber - CORRECT ANSWER-=long,thin extension from the cell body
that functions to?
-send outgoing electrical signals

axon terminal - CORRECT ANSWER--Stores neuron's communication chemical
messenger.
-Neurotransmitter

-Neurotransmitter - CORRECT ANSWER-chemical messenger.

Epithelial Tissue - CORRECT ANSWER-layer/sheet of adjacent cells that cove
internal & external surface.
-internal lining (lines lumen[open space] of organs)

Lumen - CORRECT ANSWER-open space

gland - CORRECT ANSWER-(a specialized type of epithelial
tissue),
*cells that produce and release cellular products
known as secretion

Adjacent cells are tightly connected/linked preventing
material form escaping/leaking unless? - CORRECT ANSWER-tissue has a
gland

Characteristics of Epithelial Tissue - CORRECT ANSWER-1)Cells are tightly
bound together
2)Tissue has polarity (2 different "poles" or sides)
3)Seperated from other tissues by attaching to a basement membrane
4) No blood vessels tissue obtains nutrients from deeper tissues
5) Regenerative - old cells are constantly replaced

, *Apical Surface - CORRECT ANSWER-exposed surface

*Basal surface - CORRECT ANSWER-deep surface

Functions of Epithelial Tissue - CORRECT ANSWER-Physical protection of
organs and tissues,
Control permeability (ch3 review)
-All substances that enter/leave body cross epithelia
Provide sensations via receptors
-Allows response to enviornment
Produce specialized secretions via glandular epithelium.

Exocrine glands - CORRECT ANSWER-Exocrine glands secretes substances
that are released where? On the surface or
into a cavity (Relies on ducts!)

Endocrine gland - CORRECT ANSWER-secrete where? Into surrounding
fluid/blood

Integrity Maintenance, - CORRECT ANSWER--Ensuring the issue is completely
closed/sealed so it performs its functions properly

1)Intercellular connections? - CORRECT ANSWER-*Connections shared among
adjacent cells
*Forms. Wall/sheet of cells

*Ex. A cut in skin exposes body to pathogens

2)Attachment to the basement membrane - CORRECT ANSWER-*Separate
"epithelial tissue" form the deeper "connective tissue"

Epithelial cell maintenance and repair. - CORRECT ANSWER-*via high rate of
cell turnover/division by germinative cells

germinative cells - CORRECT ANSWER-- stem cells of epithelial tissue
