Transcript of Tissues

TISSUES
Tissues come from different Germ Layers
Ectoderm=
Skin, Lining of Mouth, Sweat Glands, Hair, Nervous System, Eyes
Mesoderm=
Muscles, Skeleton, Blood, Blood Vessels, Dermis,
Connective Tissue, Epithelials
Endoderm=
Lining of digestive tract, Bladder, Lining of Urethra, Secretory Glands
Epithelial
Muscle
Connective
Nervous
Functions of Epithelial Tissue
Protection
Sensory Function
Secretion
Absorption
Excretion
All epithelial tissue has a Basement Membrane
The basement membrane protects the underlying tissue from damage.
This structure helps
the tissue adhere to
the underlying tissue
Epithelial tissue is avascular meaning it has no blood vessels.
Therefore the epithelial tissue must be fairly thin.
Epithelials come in 3 Shapes
Squamous
Cuboidal
Columnar
Also in 3 Layer Types
Simple
Stratified
Psuedostratified
It can also Be
Transitional
Simple Squamous
One layer of flattened Cells.
Located in the Alveolus of the lungs
and lines all organs.
Simple Cuboidal
One layer of cube shaped cells
Simple Cuboidal tissue is found
in the tubules of the kidneys
Simple Columnar
Simple columnar tissue is found in the small intestines. They have goblet cells that produce mucous to line tissues to moisten.
Stratified Squamous
Stratified squamous tissue is found in the skin. Keratin is a protein that waterproofs the skin preventing loss of water.
Pseudostratified Columnar
Pseudostratified columnar epithelial tissue are located in the respiratory and female reproductive systems.
They have many goblet cells to produce mucous.
Transitional
Transitional epithelium has a special property
of the ability to stretch.
What organs need to stretch?
Glandular Epithelium
Endocrine and Exocrine glands are found all over the body

Exocrine=glands that secrete fluids or products onto the surface of tissue or another organ, i.e. Sweat Glands, Salivary Glands, and Digestive Glands

Endocrine=glands that secrete products directly into blood stream. Pancreatic glands, Hormonal glands
Function of Connective Tissue is to
Connect structures together.
Made of mostly collagen and elastin fibers
Loose
Most Widely Distributed Connective tissue.
Between most body tissues.

Composed of a good mix of
Collagen and Elastic Fibers
Adipose
Also known as
FAT tissue.
Surrounds all internal organs.
Dense (Fibrous) Regular
Found in Tendons and Ligaments
Collagen Fibers are tightly packed
Dense Irregular Fibrous
Found mostly as scar tissue in the body
Hyaline Cartilage
Most common, mix of Collagen and Elastic
Found in Nose and Rings of Throat

Elastic Cartilage
Mostly Elastic Fibers
Found in outer ear and inner nasal passage

Fibro Cartilage
Tough cartilage made of Fibrous Collagen
Found in Intervertebral Disks and Ends of long bones.

Bone
Bone is also Connective Tissue

Blood? Why would Blood Be Connective Tissue?
The Inflammatory Response
Rubor (Redness)
Calor (Heat)
Tumor (Swelling)
Dolor (Pain)
Pus
Skeletal Muscle
Attached to Skeleton
Moves the Bones
Characteristics
Striated
Multi-nucleated
Voluntary
Smooth Muscle
Moves objects through tubular organs
Process called Peristalsis (squeezing)
Characteristics
Tapered
Single Nucleus
Non-Striated
Involuntary
Cardiac Muscle
Heart Muscle moves blood through Body
Characteristics
Branched
Single Nuclei
Striated
Intercalated Disks
Involuntary
Function to conduct electrical impulses
Function to Move objects in the body
Neurons
Conduct impulses through the body
Glia
Support cells of the nervous system.
Tissue Repair
If wound is too deep or too wide
for normal healing scar tissue (Dense
Irregular) will fill in the space to prevent further damage
