4 Types of Tissue
|
Epithelial
Connective- Holds tissue (60%) Muscular - Skeletal,Cardiac Neural - Makes up Brain & Spine |
|
|
Epithelial Functions
|
Protection (Form Barriers)
Controls Permeability |
|
|
Epithelial Characteristics
|
Cells have polarity
Cells sit on basement membrane May have cilia & Microsvilli CELLS CAN REGENERATE THROUGH MITOSIS |
|
|
Simple Epithelial Tissue
|
Single layer of cells
|
|
|
Stratified Epithelial Tissue
|
Many Layers of cells - Resists wear and tear
|
|
|
Pseudostratified Epithelial Tissue
|
Looks like many Layers, but cells sit on basement membrane
|
|
|
Squamous Epithelial Tissue
|
Flat cells
|
|
|
Columnar Epithelial Tissue
|
column Shaped
|
|
|
Simple Squamous
List Function & Location |
Function :Regulate exchange of materials
Locations: Line blood vessels, Line Heart, Alveoli |
|
|
Simple Cuboidal
List Function & Location |
Function: Absorption / Secretion
Locations: Ducts of kidneys |
|
|
Simple Columnar
-> Pseudostratified Ciliated List function & Location |
Function: Move Material over surface
Locations: Line respiratory tract Line uterine tubes |
|
|
Simple Columnar
--> Non ciliated ( No cillia) List function& Locations |
Functions: Absorption/ Secretion
Locations: Line digestive tract ( May have microvilli) |
|
|
Stratified Sqamous *MOST COMMON*
List function & Location |
Functions: Protection/ Wear n tear
Location: Forms skin lines vagina mouth Esophagus |
|
|
Stratified Cuboidal
List function & Location |
Functions: Secretion ( GLANDS)
Locations: Forms sweat, salivary & Mammary glands |
|
|
Stratified Columnar
List function & Location |
Functions: protection (RARE)
Location: Lines some large ducts (URETHRA) |
|
|
Stratified Transitional
|
Functions: Flexibility (STRETCH)
Location: Lines bladder * Changes shape when stretched cuboidal --- > Squamous |
|
|
What are the two basic types of GLANDS?
|
Endocrine - Secrete hormones into blood
Exocrine- Secrete onto body surface or into body cavities |
|
|
Exocrine Cells
--> Unicellular -- > ? |
Goblet cell
|
|
|
What does Goblet cells do?
|
Secretes mucin
Mucin + water --> Mucus |
|
|
Exocrine Cells
---> multicellular --> consists of what 2 parts? |
Secretory Unit
Duct |
|
|
Classify Duct Structure
|
Simple( Unbranched)
Compound (Branched |
|
|
Classify Secretory unit
|
Tubular ( Tube like)
Alveolar ( Sac like) |
|
|
Mammary glands are what structural classification?
|
Compound Alveolar ( Branched/Sac like)
|
|
|
Intestinal glands are what structural Classification?
|
Simple Tubular ( Unbranched/Tube-like)
|
|
|
Functional Classification
Merocrine Glands |
Most exocrine glands
ex Pancreas, salivary glands, Sweat glands |
|
|
Functional Classification
Holocrine Glands |
(Holocost)
Accumulates secretory products --> cell rupture --> Release Secretion Ex. oil producing glands |
|
|
Functional Classification
Apocrine Glands |
Secretory product accumulates at tip (Apex) of cell --> tip breaks off
Ex.Mammary glands (Milk) |
|
|
Connective Tissues
Matrix -> |
What cells are embedded in
Matrix = Protien Fibres(ex elastin collagen) + Ground Substance (Ex proteins, mineral salts) |
|
|
Cells that secret fibers are called what?
|
FIBROBLASTS
|
|
|
Functions of Connective tissue
|
Supports, surrounds, connects
Transports Fluid Protects / Cushions |
|
|
What are the three types of connective tissue
|
Connective tissue Proper (eg. Loose & Dense)
Fluid C.t ( eg. Blood or lymph) Supporting C. t (eg. Bone or cartilage) |
|
|
Connective tissue proper
|
Contains Fibers ( Made of protien)
Collagen ( Strong) Elastin ( Strtechy - nose n ears) Reticular (Forms networks of fibers) |
|
|
Loose Connective tissue -
what are the three types |
Areolar
Adipose Reticular |
|
|
Arrangement & Function Of
Areolar Tissue |
Network of 3 fibers
Functions: Bind/ Hold/ Cushions |
|
|
Arrangement & Functions of
Adipose Tissue |
Around eyes *
Cells = Contain adipocytes Functions: Cells storing fat droplets |
|
|
Arrangement & Functions of
Reticular Tissue |
Network of reticular fibers
Forms Spleen/ Lymph nodes/ Bone marrow Functions: Stabilizes functional cells in these organs |
|
|
Connective Tissue Proper
What are the three types of DENSE connective Tissue |
Regular
Irregular Elastic |
|
|
Dense Connective Tissue
Regular Forms what ? & Arrangement of fibres |
Parallel Collagen fibers
Forms Ligaments, Tendons. Fascia |
|
|
Dense Connective Tissue
Irregular Forms what ? & Arrangement of fibers |
Dense network of collagen fibers
Forms DERMIS of skin |
|
|
Dense connective Tissue
Elastic Forms what? & Arrangement of fibers |
Thick parallel elastic fibers ( STRONG & STRETCHY )
Forms Vocal cords, aorta |
|
|
Cartilage
|
Lots of collagen
Holds water forms a gel (50% water) Cells - Chondrocytes (Sit in spaces called lucunea) PIC ON PAGE 2-8 |
|
|
Function of Cartilage?
|
Cushioning / Flexability
|
|
|
Types of Cartilage? x3
|
Hyaline-Supports/ cushions
Location: ends of long bones Elastic- Most flexable cart. Location Outer Ear, Epiglottis Fibrocartilage- Parallel bundles of collagen- > resist compression Location: Intervertebral discs, Knee joints- |
