2. SIMPLE SQUAMOUS
It consists of only one layer of flat, scale
like cells. Substances can readily diffuse
or filter through this type of tissue. The
microscopic air sacs of the lungs are
composed of this kind of tissue, as are
the linings of blood and lymphatic
vessels and the surfaces of the
pleura, pericardium, and peritoneum.
3. STRATIFIED SQUAMOUS
It is characterized by multiple layers
of cells with typical flattened
squamous cells at the free of the
epithelial sheet. The presence of
keratin in these cells contributes to
the protective qualities of skin
covering the body surface.
4. TRANSITIONAL EPITHELIUM
It is a stratified tissue found in body
areas, such as the wall of the urinary
bladder, that are subjected to stress and
tension changes. As tension
increases, the epithelial sheet is
expanded, the number of observable cell
layers decreases, and cell shape
changes from cuboidal to squamous in
appearance.
5. SIMPLE COLUMNAR EPITHELIUM
It composes the surface of the
mucous membrane that lines the
stomach, intestine, uterus, uterine
tubes, and parts of the respiratory
tract. It consists of a single layer of
cells, many of which have a
modified structure.
6. STRATIFIED COLUMNAR
It has multiple layers of columnar
cells, but only the most superficial cells
are truly columnar in appearance. It is
found in few places in the human body
and it’s located in segments of the male
urethra and in the mucous layer near the
anus.
7. PSEUDOSTRATIFIED COLUMNAR
EPITHELIUM
It is found lining the air passages of
the respiratory system and certain
segments of the male reproductive
system such as the urethra. Only a
layer of irregularly shaped
columnar cells touches the
basement membrane.
8. SIMPLE CUBOIDAL
It is composed of one layer of
cuboidal cells resting on a
basement membrane. This type is
seen in many types of glands and
their ducts, and it’s also found in
the ducts and tubules of other
organs such as the kidney.
9. STRATIFIED CUBOIDAL EPITHELIUM
It serves as protective function. It
can be located in the sweat gland
ducts, in the pharynx, and over
parts of the epiglottis. Two or more
rows of low cuboidal cells are
arranged randomly over a basement
membrane.
10. GLANDULAR EPITHELIUM
It is specialized for secretory
activity. It depends on complex
and highly regulated cellular
activities requiring the
expenditure of stored energy.
11. CONNECTIVE TISSUE MEMBRANES
-They don’t contain epithelial components
-Synovial membranes- line the spaces between the bones
and joints that move are classified as connective tissue
membranes
-They help reduce friction between opposing bones in
movable joints
-They have smooth and slick membranes that secrete the
synovial fluid
-Helps in reducing friction between opposing surfaces in a
movable joint
-Synovial membranes also line bursae sacks.
12. MUSCLE TISSUE
Skeletal: form of striated muscle tissue existing
under control of the somatic nervous system . It
moves and supports the skeleton. Used to
facilitate movement, by applying force to bones
and joint.
Smooth: found in various parts of the body
like, the arteries, the bladder and the digestive
tract.
Cardiac: found in the heart. Cell are joined to one
another by intercalated discs which allow the
synchronization of the heart beat. Cardiac
muscle is branches, striated muscle
13. NERVOUS
The nervous system is a complex network of
nerves and cells that carry messages to and
from the brain and spinal cord to various parts
of the body.
The nervous system includes both the central
nervous systems and peripheral nervous
system
The central nervous system Is made up of the
brain and spinal cord and the peripheral
nervous system is made up of somatic and the
autonomic nervous systems
