TISSUES
MUSCLES
The skeletal muscle are the muscles that when you touch your skin you can feel and move. they are muscles that are attached to your bones, to help you move and protect your bones.(4)
The smooth muscle can
be found in the wall of
hollow organs, like the
stomach. Its there to
protect the organs but
isn’t as colorful as the
skeletal muscles, they
blend in with the walls
of the organs. (4)
The cardiac muscle is the muscle in the
walls of the heart, its a lot like the
skeletal muscle and the smooth muscle
because it can be involuntary like the
skeletal, which means that it is
controlled by the nervous system, but if
it didn’t have a nervous system it would
also be voluntary like the smooth
muscle, which controls itself. (4)
NERVOUS
Nervous tissue is made of neurons and neurological cells, that transmit electrical signals. (4)
Soma:
The part
of the cell
that
contains
the
nucleus.
(4)
Dendrites:
extending from
the soma,
receives
information and
moves it toward
the soma. (4)
Axon (nerve fiber):
Transports
information away
from the soma. (4)
Simple Squamous-Physically flat, scalelike cells. Substances can easily diffuse through this tissue. The microscopic air sacs in the lungs are made of this tissue. (4)
Stratified Squamous-
Keratinized is made up
of multiple layers of cells
with flattened squamous
cells at the outer
surface. Possesses
keratin which
contributes to its
protective qualities (ex.
Skin) (4)
Transitional- stratified;
found in body areas
that are subjected to
stress and tension
changes (ex. Urinary
bladder) As tension
increases, the cell will
change from a cuboidal
shape to squamous.
This transition protects
the distensible
structures from tearing.
(4)
Stratified
Columnar-
multiple layers of
columnar cells,
although only the
closest cells to the
surface look
columnar in
shape. Rare in the
human body,
found only in the
male urethra and
in the mucous
layer near the
anus. (4)
EPETHELIAL
Pseudostratified- found in the lining of air passageways in the respiratory system and in areas of the male reproductive system. Only a single layer of irregularly shaped columnar cells touches the basement membrane, and because of the differing heights, many are not tall enough to reach the upper surface of the epithelial sheet. (4)
Simple Cuboidal-
made of one layer of
cuboidal cells resting
on a basement
membrane and
makes up glands and
their ducts (ex.
Kidney) (4)
Stratified Cuboidal-
Protective function; at
least two rows of low
cuboidal cells are
randomly arranged at
the basement
membrane. Located in
sweat glands ducts,
pharynx and parts of the
epiglottis. (4)Glandular- specialized for
secretory activity in the
glands. Able to function
unicellular or in clusters or
specialized follicles like
multicellular glands. (4)
EPETHELIAL
Fiber types include:
•Collagenous fibers:
strong and flexible
fibers that appear as
wavy bundles in
tissue sections.
•Reticular fibers: thin
collagen fibers
coated with a
glycoprotein. They
tend to branch
extensively forming
delicate networks.
•Elastic fibers:
consist of the protein
elastin, which allows
for stretching and
recoiling. (5)
Areolar connective
tissue consists of a loose
arrangement of fibers. It
contains all of the cell
types mentioned, as
well as all three fiber
types. Areolar also has
an abundance of ground
substance, which
appears white in tissue
preparations.(5)
Adipose tissue
consists of adipocytes,
which store fat
droplets. The nucleus
of the adipocyte is
located adjacent to
the plasma
membrane.(5)
