4 General types of Tissues?
1 Epithelial
2 Connective
3 Muscle
4 Nervous
What is the lacation of Epithelal Tissue?
Inner lining of body cavities
hollow organs
In glands
What are the Characteristics of Epithelial Tissue?
One portion is conected to CT by the basement membrane.
No vascular supply recieve nutrients rid wastes by simple diffusion W/ CT. Go through cell cycle alot replaceing damaged tissue.
What are the functions of Epethelial tissue?
Protection for underlying tissue from Physical, Chemical, and infection.
Used in Secretion
Used in excretion "Wastes"
Used in absorption
Simple Squamous
Location & Function
Found in Lungs
Lones blood vessels
Things travel through easly thin
Stratified squamous
Location & Function
Found in Skin, Mouth, Vagina
Provides protein to underlying tissues
Simple cuboidal
Location & Function
Found in pancreas Covers Ovaries.
Secretion forms tubes
Stratified Cuboidal
Location & Function
Found in Mammary glands Salivary Glands.
Secretion
Simple Columnar
Location & Function
Covers uterus and digestive tract.
secretion of enzymes and absorption of products.
Pseudostratified Columnar
Location & Function
Lines passage ways of respiratory systems.
Secrete mucus to trap materials or possess cilia to trap particles,cells.
Stratified Columnar
Location
Function
Found in males, Urethra Van deferens
Glandular
Found embedded in Columnar or cuboidal epithelium and form glands
What 2 glands are found in Glandular
Exocrine Glands- secretes some products onto/into some internal or external surface.
Endocrine Glands-Secretes hormones into the blood
Connective Tissue:
Characteristics1-5
1.Cells farther apart
2.Space filled with non-living material called matrix.
3. reproduce continuously
4.Vascular tissue embedded and typically well nourshed.
5.Contains variety of cells
Connective Tissue:
Functions1-7
1.Bind structures together
2.provide support and protection
3.structural material
4.store fat
5.produce blood cells
6.protect against infection
7.repair some tissue damage
What is a fibroblasts and chondrocytes?
1.Lagre star shaped cells that produce long thread like fibers that form matrix.
2.Mature cells of cartilage produce a non-living spongy matrix.Gives cartliage a spongy consistency shock absorber.
What is matrix?
Space between cells that is made up of Collagen Fibers and Elastic fibers.
Elastic fibers
Collagen Fibers
1.Thin fibers Composed of protein elastin allows matrix to be stretchy.
2.thick fibers composed of protein collagen parrallel bundles flexible and strong.
Where are fibroblasts and chondrocytes found?
1.any tissue with the name connective tissue.
2.only in Cartilage.
DENSE CONNECTIVE TISSUE
Dense Regular CT:
Charcteristics
Location
1.Large collagen fibers run parallel to one another.With stand continuous pulling in one direction.small amount of vascularization.
2.Tendons & Ligaments
Dense Irregular CT:
Charcteristics
Location
1.Large collagen fibers randomnly woven into matrix. Resists pulling in many directions.fibroblasts present few.
2.Heart valves & Dermis
Elastic CT:
Charcteristics
Location
1.Many long elastic fibers found parallel. allows tissue to stretch.
2.Lung tissue & Trachea
LOOSE CONNECTIVE TISSUE
Charcteristics
Location
1.Contains all fibers but few fibers. Provides strength, elasticity and support in all directions
2.Hypodermis and Mucous membranes
Adipose Tissue:
Charcteristics
Location
Specialized form of CT stores fat molecules in cytoplasm. Born with limited amount fat is stored cells get bigger.
2.Beneath the skin & between muscles
Cartilage
No blood vessels or nerves found within cartilage heals slowly.
KINDS OF CARTILAGE:
1-3
1.Hyaline Caqrtilage
2.Fibrocartilage
3.Elastic cartilage
Hyaline cartilage:
Charcteristics
Location
1.Most abundant of all cartilage very fine fiber cant see with microscope Many chondrocytes in lacunae.
2.Ends of long bones & nose
Fibrocartilage:
Charcteristics
Location
Chondrocytes are scattered among clearly visible bundles of collagen fibers.
2.intervertebral discs
Elastic Cartilage:
Charcteristics
Location
Chondrocytes located in between a network of elastic fibers cartilage is tuff yet flexible.
2.external ear
Bone Tissue:
Osteocytes found in lacunae are in tough calicium and collagen based matrix
Two types of bones?
Compact bone
Spongy bone
What are lacunae?
A hollow cavity with cells in them.
Two types of tissue lacunae are found in?
Bone and cartilage
Blood
A connective tissue with liquid matrix called plasma
Three types of blood cells and functions?
1.Red blood cells-Carry oxygen
2.White blood cells-fight disease
3.Platelets-cell fragments used in blood clotting
What does dense refer to?
The density of fibers within the tissue.
What does loose refer to?
Tissue contains few fibers.
What are the three types of muscle tissues?
1.Skeletal muscle
2.smooth muscle
3.Cardiac muscle
Skeletal muscle:
Location & Function
1.Any muscle connected to the skeleton.
2.Move bone or skin moved consciously
