Anatomy and Physiology Lab 1

Histology

study of tissues

“MICROSCOPIC ANATOMY”

-study of tissues

-Many diseases are diagnosed at the tissue level

What are tissues made from?

Tissues are made of cells and extracellular material

-all tissues arise from stem cells

-Hematoxylin stains the nucleus purple and eosin colors cytoplasm pink

Why is histology important ?

Many diseases are diagnosed on the tissue level

What are Stem cells?

-unspecialized and undifferentiated cells that have the ability to produce more stem cells

Four types of tissue

1. Connective

2. Epithelial

3. Nervous

4. Muscular

What is the Epithelial tissue?

squamos,cuboidal, columnar, simple and stratified

Epithelial slides

Simple squamos

simple columunar

simple cuboidal

pseudostratified columnar

stratified squamous

transitional epithelium

Muscular Tissue

Smooth

Skeletal

Cardiac

Connective Tissue

adpose tissue

Epithelial Tissue

squamos

cuboidal

columunar

simple

stratified

Simple Epithelium

Simple Squamous epithelium lines the air sacs and blood vessels

Endothelium

simple squamos epithelium of blood vessels

Mesothelium

surface layer of many membranes

Simple Cuboidal Epithelium

-these cells form many major glands and glandular organs of the body

-sceretion of fluids(sweat and oil)

Simple Columanr Epithelium

=mucus secretion goblet cells

-uterine tubes

Pseudostratified columunar

-rests on respiratory passage

Stratified squamos Epithelium

vaginal canal and mouth
