Tissue
Epithelial Connective Nerve Muscle
• 4 types; epithelial, connective, nerve, muscle
• Group of similar cells and function

Epithelial
Simple Squamous Simple Cuboidal Simple ColumnarStratified Squamous Stratified Cuboidal Stratified Columnar Psuedostratified Columnar TransitionalTissue
• Composed of almost entirely of cells
• Apical and basal surfaces
• Supported by connective tissue
Google.com
Simple Squamous
Epithelial
• Has one layer of tissue• A flatten looking tissue• Has a disc-shaped
nucleus and cytoplasm is sparse
Google.com
Simple Cuboidal
Epithelial
• Cube-like cells in a single layer
• Secretion and absorbtion
Simple Columnar
Epithelial
• These are tall; single layered tissues
• Have oval nuclei• Also functions in
absorption and secretion
Stratified Squamous
Epithelial
• Thick membrane• Composed of several
layers of cells
Stratified Cuboidal
Epithelial
• Rare in body
Stratified Columnar
Epithelial
• Limited distribution in the body
Psuedostratified Columnar
Epithelial
• Single layer of cells with different heights
• Some cells don’t reach the free surface
Transitional
Epithelial
• Several layers• Basal cells are cuboidal,
surface cells are done shaped
Connective
Areolar Reticular Adipose Tissue
• Functions are protection, insulation, transportation, and binding
• Mesenchyme is their tissue of origin
• Have a nonliving extracellular matrix
Google.com
Areolar
Connective Reticular Adipose
• Has a gel-like matrix• Has all 3 connective
tissue fibers
Reticular
Connective Areolar Adipose
• They lie in a fiber network
• Are a loose ground substance with reticular fibers
Adipose
Connective Areolar Reticular
• Matrix is similar to that of the areolar tissue
• Have closely packed adipocytes
Proper Dense Regular
Connective
• Have parallel collagen fibers
• They also have a few elastic fibers
Google.com
Proper Dense Irregular
Connective
• Irregularly arranged collagen fibers
• Some elastic fibers found
Google.com
Bone
Connective Blood Hyaline Cartilage Fibrocartilage Elastic Cartilage
• Also known as osseous tissue
• Hard and calcified matrix
• Collagen fibers found in bone
Blood
Connective Blood Hyaline Cartilage Fibrocartilage Elastic Cartilage
• Contained in vessels
Hyaline Cartilage
Connective
• Amorphous and firm matrix with imperceptible networks of collagen fibers
• Chondrocytes lie in the lacunae
Fibrocartilage• The matrix is similar to
that of hyaline cartilage• Less firm with thick
collagen fibers
Google.com
Elastic Cartilage• Also similar to hyaline
cartilage• Has more elastic fibers
Nerve• Have branched neurons• Have long cellular
processes
Muscle• Composed of the
muscles and tendons• Allows manipulation of
the environment, locomotion, and facial expressions
Google.com
Skeletal• Long and cylindrical
shape• Have multinucleate cells
with very pronounce striations
Google.com
Smooth• Spindle shaped cells• Central nuclei and no
striations
Cardiac• Branching and striated
cells• Uninucleate cells
interlock at intercalated discs
