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
