Epithelial Tissue
Simple Squamous
Stratified Squamous
Single layer, basement membrane to the free surface - gas can easily diffuse across Ex: lungs
More than 1 layer, only deepest layer attaches to basement membrane - protection and reduce water loss Ex: epidermis skin
Cell Types of Connective Tissue
"blasts" – create/form bone
"cytes" - maintain bone
"clasts" - break it down
1) a cell body
2) dendrites
3) an axon

Stratified Cuboidal
Functions of Epithelial Tissue
Covers and lines cavities/ducts
Avascular- no blood
Is capable of cell regeneration
Free/ basal surface
Simple Cuboidal
Stratified Cuboidal
Active transport, facilitated diffusion, and secretions Ex: kidney, glands, ducts
Provides protection Ex: Parts of reproductive system, Larger ducts of sweat glands
Fibroblasts produce 3 types of fibers
Collagen fibers: thick, great strength; bone, cartilage, ligaments, tendons
Elastic fibers: thin, easily stretched; vocal cords, skin, lungs, blood vessels
Reticular fibers: thin, supporting networks; spleen, lymph nodes
Nervous tissue can be found here
brain
spinal cord
nerves

Endoplasmic Reticulum
Functions of Connective Tissue
Most abundant/ primary tissue of the body, binds
supports, strengthens, insulates, and transports
Simple Columnar
Pseudostratified Columnar
Provides protection and contains cilia Ex: respiratory ad digestive tract
Provides protection and secretes mucus Ex: respiratory system
Loose
Dense
Loose: most common, binds tissues together
Dense: strong collagen, makes tendons and ligaments
Cardiac
Located in the heart
Striated
Involuntary control (unconscious control)
Picture 3
Simple Columnar
Function of Muscle Tissue
Mobility, stability, posture, circulation
Transitional Epithelial
Accommodates changes in fluid volume
Ex: Bladder, urethra, ureters
Cartilage
Bone
Cartilage: avascular, heals poorly, covers articular surfaces (joint)
Bone: Protection and attachment site for muscles
Skeletal
Attaches to our skeleton and allow the body to move
Striated
Voluntary control (conscious control)
Picture 4
Bone tissue
Function of Nervous Tissue
Coordination and control of body activity
Glandular epithelium
Supported by a network of connective tissues
Endocrine Gland- no ducts, hormones
Exocrine Gland- ducts, sweat and saliva
Blood
Transportation of gas, nutrients, and hormones
Smooth
Not striated
Involuntary control (unconscious control)

Nervous Tissue
What are the four tissue membranes
Skin, mucous, serous, synovial
