What are the four basic tissues? |
1) Epithelial Tissue 2) Connective Tissue 3) Muscle Tissue 4) Nerve Tissue |
|
What is Epithelial Tissue? |
Epithelial Tissue - Covers exposed surfaces - lines hollow organs, internal passageways and ducts (digestive tract, urinary tract, reproductive) - forms glands |
|
What is Connective tissue? |
Connective Tissue - Material found between cells - Support and binds structures together - Stores energy as fat - Provides immunity to disease |
|
What is Muscle tissue? |
Muscle Tissue - Cells shorten in length producing movement |
|
What are the two types of muscle tissue? |
Voluntary, which includes skeletal Involuntary, which includes cardiac and smooth |
|
What are Nerve tissues? |
- Cells that conduct electrical signals - Detects changes insides and outside the body |
|
What are the general features of Epithelial Tissue?
|
- Cellularity - Special contacts - Polarity - Basement membrane - Avascular - Regeneration |
|
What is the basement membrane? |
Basement membrane - Supported by connective tissue; reticular and basal laminae |
|
What are the functions of epithelial tissue? |
- Physical protection - Absorption - Excretion - Produces secretions - Provides sensation - Specialized Epithelium |
|
If epithelial tissue has microvilli then what would be its specialization? |
- Absorption/ secretion - It would most likely be found in the digestive and urinary tracts |
|
If epithelial tissue has cilia, then what would be its specialization? |
- Movement - It would mostly likely be found in the respiratory tracts, the synchronized beating moves mucous up from lungs to throats |
|
Where can you find Simple Squamous Epithelium? |
You can find it in the - Lining of ventral body cavities - Alveoli of Lungs - Inner lining of Cornea - Lining of heart and blood vessels |
|
When can you find Stratified Squamous Epithelium? |
- Surface of skin - Lining of mouth - Throat - Esophagus - Rectum - Anus - Vagina |
|
Where can you find Simple Cubodial Epithelium? |
- Glands - Ducts - Portion of kidney tubules |
|
Where can you find Stratified Cubodial Epithelium?
|
- Linings of sweat gland ducts - male uretha |
|
Where can you find Simple Columnar Epithelium? |
- Lining of stomach - Intestine - Gall bladder - Uterine tubes |
|
Where can you find Stratified Columnar Epithelium? |
- Small areas of pharynx - Epiglottis - Mammary Glands - Salivary Glands Ducts - Urethra |
|
Where can you find Pseudostratified Ciliated Columnar Epithelium? |
- Lining of nasal cavity - Trachea - Bronchi - Portion of the male reproductive tract |
|
Where can you find transitional epithelium? |
- Urinary Bladder - Ureters |

Transitional Epithelium |
|
What type of tissue is this? |
Pseudo stratified Epithelium |
|
What type of tissue is this? |
Pseudo stratified Epithelium |
|
What are exocrine glands? |
- Cells that secrete - sweat, tears, milk, ear wax, saliva, digestive enzymes onto free surface of epithelial layer
- Connected to the surface by tubes (ducts) |
|
What are endocrine glands? |
- Ductless glands (e.g. thyroid, pituitary, adrenal glands) - Secrete hormones into the bloodstream |
|
In connective tissues, do the cell touch? |
They rarely touch due to extracellular matrix |
|
What is the connective tissue matrix? |
The matrix is made up of fibers & ground substance secreted by cells |
|
What are the three (3) connective tissue? |
* Connective Tissue Proper * Fluid Connective Tissue * Supporting Connective Tissues |
|
What are the connective tissue proper? |
* Loose Connective Tissue * Dense Connective Tissue |
|
What are Loose Connective Tissue? |
Fibers create loose, open framework - areolar tissue - adipose tissue - reticular tissue |
|
What are Dense Connective Tissue?
|
Fibers densely packed - dense regular - dense irregular elastic |
|
What are the Fluid Connective Tissues? |
- Blood - Lymphs |
|

|
What are cartilage?
|
- Solid, rubbery matrix - Hyaline cartilage - Elastic cartilage - Fibrocartilage |
