CHAPTER 2, SECTION 3 NOTES● Types of Tissue

○ Epithelial tissue - _____________________________________________○ Connective tissue - ___________________________________________○ Muscle tissue - ______________________________________________○ Nerve tissue - _______________________________________________

● Epithelial Tissue○ What is Epithelial Tissue?

■ __________________________________________________________________________________________________________

■ Includes epithelia and glands■ Is replaced frequently

○ Functions of Epithelial Tissue■ ___________________________________________■ Control substances entering and leaving the body■ Provide sensory information■ ___________________________________________

○ Types of Epithelial Cells■ Squamous - Flat cells■ Cuboidal - _____________________■ Columnar - Column like, tall

○ Epithelial Cell Arrangements■ Simple - ____________________________________________■ Stratified - ___________________________________________■ Transitional - _________________________________________

○ Simple Squamous■ Found in _________________________________ (gas exchange)■ Lining of the abdominal cavity■ Endothelium of blood vessels■ ___________________________________________________

○ Simple Cuboidal■ Renal tubules (tubes in the kidney)■ Secretory glands■ ___________________________________________________

○ Simple Columnar■ Also found in kidneys■ ___________________________________________________■ Have secretory and absorptive properties too

○ Stratified Squamous■ Skin surface

■ Mouth and throat■ Anus and rectum■ _____________________________________________________

_____________________________________________________○ Stratified Cuboidal & Columnar

■ Cuboidal● ______________________________

■ Columnar● Pancreatic ducts● ______________________________

○ Glands■ _____________________________________________________■ Endocrine glands secrete __________________________

● Pancreas/Insulin■ Exocrine glands secrete ___________________________

● Skin/Sweat● Connective Tissue

○ Functions of Connective Tissue■ Strengthens the body and organs■ _____________________________________________■ Maintains the shape of organs■ Provides rigid framework for muscles to pull

○ Types of Connective Fibers■ Collagen - _______________________________■ Reticular fibers - __________________________■ Elastic fibers - ____________________________

○ Classes of Connective Tissue■ Connective tissue proper

● Wide variety of locations and functions● Plays a role in immune defenses

■ Cartilage● Provides support and flexibility● _______________________________________________

■ Bone tissue (osseous tissue)● Provides framework, protects organs, supports body

■ Blood● Provides transportation, regulation● Carries oxygen and nutrients, and carbon dioxide

○ Types of Connective Tissue■ Connective tissue proper can be divided into two categories

● Loose - Tough, but flexible

○ Areolar - Underneath epithelia. Holds stuff together○ Reticular - Found in lymphnodes, bone marrow,

spleen○ Adipose tissue - Padding, insulation, shock absorption

● Dense - Many collagen fibers. Strong○ Provides tensile and structural strength○ Can be regular or irregular○ Makes up:

■ Cartilage■ Tendons■ Ligaments■ Bone

■ Cartilage● Connective tissue found on the ends of bones at the joint

surfaces■ Types of Cartilage

● Chondroblasts - Cartilage cells○ Secrete extracellular matrix

● Hyaline Cartilage○ ___________________________________________

● Elastic Cartilage - Springy○ ___________________________________________

● Fibrocartilage - Tough○ ___________________________________________

■ Bone - Osseous Tissue● Protects organs● Supports the body● Cortical Bone - ____________________________________● Cancellous Bone - _________________________________

● Muscle Tissue○ Types of Muscle Tissue

■ Skeletal - _____________________________________________■ Cardiac - ______________________________________________■ Smooth - ______________________________________________

● Nervous Tissue○ Conveys information by electrical signaling○ Divided into two sections

■ Central Nervous System● __________________________● __________________________

■ Peripheral Nervous System● Sensory nerves throughout body

○ Neurons■ The cell that makes up neural tissue is called the Neuron.

■ They generate, transmit, and receive electrical signals
