Epithelial Tissue
Simple Squamous
Outer layer of skin aka “epidermis”
Simple Squamous
Cheek Cell Smear
Lung tissue is simple squamous for
gas exchange!
Simple Squamous
Stratified Squamous
(more than one layer of cells)
Stratified Squamous
Simple Cuboidal
Single layer of “square” cells
Cuboidal cells are designed to
secrete, like those found in the
kidneys
Simple Cuboidal
Transitional epithelium includes
squamous and cuboidal cells.
• This tissue is found in the bladder and other
organs that are designed to stretch!
Simple Columnar
In the small intestine (jejunum)
• Columnar cells
ABSORB, ABSORB,
ABSORB!!
• What do they absorb
in the intestines?
Pseudostratified columnar cells can
also have cilia, like in the trachea.
The cilia are hair-like
structures that . . .
• AID IN MOVING
SUBSTANCES like
mucus, dust, and
foreign particles
Connective Tissue
Adipose (Fat Cells)
Adipose
Hyaline Cartilage
(Chondrocytes)
• Found in the rib cage
and septum of the
nose
• Allows expansion of
lungs while breathing
Hyaline Cartilage
Elastic Cartilage
(Chondrocytes)
• This is the bendable cartilage found in the ears.
Bone
(Osteocytes)
Bone
Blood
(Erythrocytes and Leukocytes)
Muscle Tissue
All cells are called fibers!
Smooth
• Smooth muscle is
stringy
• Found in all major
organs
• Involuntary with one
nucleus per cell
Smooth Muscle
Skeletal Muscle
• Has striations that
make the fibers
appear banded
• Tissue is voluntary
and attached to
bones
• Several nuclei per
fiber
Skeletal Muscle
Cardiac Muscle
• Fibers have striations
but are also branched
• Tissue is involuntary
and found in the heart
• One nucleus per fiber
Cardiac Muscle
Nervous Tissue
All tissue is made of neurons.
• Neurons appear as starshaped cells in the brain
(cerebrum and cerebellum)
and the spinal cord
Nerve Cells
