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
