4 major types of tissue
neural/nervous system
Muscle tissue
Connective tissue
Epithelial tissue
Is found in:
Functions:
.
Is found in:
Cardiac muscle
Smooth muscle
Skeletal muscle
Responds to stimulation and contracting to provide movement, and occurs as three major types: skeletal (voluntary) muscle, smooth muscle, and cardiac muscle in the heart.
Example:
The heart pumping blood throughout the body
Is found in:
.
nerves
Spinal cord
Brain
Functions:
allows the propagation of electrochemical signals in the form of nerve impulses that communicate between different regions of the body
example:
The brain sends signals to the rest of the body to perform functions
Lining of GI tract organs and other hollow organs
Skin surface (epidermis)
Functions:
the sheets of cells that cover exterior surfaces of the body, line internal cavities and passageways, and form certain glands.
examples:
the skin
is found in:
functions
binds the cells and organs of the body together and functions in the protection, and support, of all parts of the body
.
Fat and other soft padding tissue
Bone
Tendon
examples:
The bones supporting the whole body
.
Supporting and Protecting: The skeleton, tendons, and ligaments create a bony framework to support the body, protect delicate organs, and surround and interconnect other tissues
Transporting Materials: Fluid connective tissue (blood and lymph) quickly move dissolved materials from one part of the body to the other
Store Energy Reserves: Stores energy in adipose (fat) tissue until needed - fat also provide insulation and padding
Defending the Body: Specialized connective tissue cells form our immune system, which protects us from foreign invaders
Different types of connective tissue:
Types:
stratified
transitional epithelial
pseudostratified columnar epithelium
Simple
simple squamous epithelium
structure
location
Kidney, air sacs of lungs, lining of heart, blood vessels, and lymphatic vessels; lining of ventral body cavity(serosae)
Function
Allows passage of materials by diffusion and filtration, secretes lubricating substances in serosae.
flat, one layer, not perfect squares
simple cuboidal epithelium
function
structure :
location
secretion and absorption
( 
)
Kidney tubules; ducts and secretory portions of small glands, ovary surface.
flat, one layer, almost perfect squares
simple columnar epithelium
structure
function
location
digestive tract (stomach to anal canal), gallbladder and excretory ducts of some glands; ciliated variety lines small bronchi, uterine tubes, and some regions of the uterus.
flat, one layer, long, can be ciliated or not
( 
)
Absorption; secretion of mucus, enzymes
stratified squamous epithelium
.
Supporting connective tissue come in two types, cartilage and bone. These tissues are less diverse and have a matrix of dense ground substance and closely packed fibers, which give them the strength and rigidity to support the rest of the body.
Fluid connective tissue have distinctive populations of cells suspended in a watery ground substance that contains dissolved proteins. The two fluid connective tissues of the body are blood and lymph.
Connective tissue proper refers to connective tissues with many types of cells and fibers surrounded by a syrupy ground substance. Examples are tissue that underlies the skin, fatty tissue, tendons, and ligaments.
stratified columnar epithelium
structure
function
location
forms the moist lining of the esophagus, mouth, and vagina
( 
)
like the simple squamous but multiple layers and seem more distorted
protects underlying tissues in areas subject to abrasion
stratified cuboidal epithelium
structure
function
location
Largest ducts of sweat glands, mammary glands, and salivary glands.
( 
)
like the simple cuboidal epithelium except there are multiple layers. in this pic it looks more like squares than cubes
protection and secretes
structure
function
location
small amounts in male urethra and some glands
( 
)
protection and secretion
like simple columnar but it has multiple layers
location
structure
function
lines the ureters, urinary bladder, and part of the urethra
stretches and expands urinary organs
many different epithelium shapes on different layers
structure
function
location
Linings of respiratory passages
Protection, secretion, movement of mucus
messier and less straight version of columnar epitheliums
