1 Tissues Human Biology

2 Tissues Groups of cells that are specialized in function or structure
Epithelial Connective Muscle Nervous

4 Epithelial Tissue Cover all body surfaces Line all organs
Major part of glands Have “free” outside Tightly packed cells Functions: Lining, sensory, secretion, absorption, excretion

5 Definitions Squamous Cuboidal Columnar Stratified
Think “squat” flattened cells Cuboidal Cube shaped Columnar Elongated cells Stratified “Layered”

6 Epithelial Tissues Types
Make a table in your notes like this: (8 X 3) Epithelial Type Location (lining) Function

7 Simple & Stratified Squamous Tissue

8 Epithelial Type Location (lining) Function Simple Squamous Air sacs of lungs, blood vessels lubrication Stratified Squamous Skin, mouth... protection Simple Columnar Pseudostratified Columnar Stratified Columnar Simple Cuboidal Stratified Cuboidal Transitional

9 Simple & Stratified & Pseudostratified Columnar Tissue

19 What are tissues? Groups of cells that are specialized in function or structure What are the four types? Epithelial Connective Muscle Nervous

20 Connective Tissue Fucntions “connects” substances Protect Act as frame
Fill spaces Produce blood Repair tissue damage

21 Connective Tissue Make a table in your notes like this: (7 X 3)
Connective Tissue Type Location (lining) Function

22 Connective Tissue Types
Loose Fibrous Contains elastin Connects skin to organs Provides blood vessels to skin Fills muscle gaps

23 Connective Tissue Type
Location (lining) Function Loose Fibrous Under skin, in muscle Nourishment, stretch

24 Connective Tissue Types
Adipose Similar to loose fibrous Contains fat storage Insulation, cushions joints, energy reserve Fat droplet

25 Connective Tissue Type
Location (lining) Function Loose Fibrous Under skin, in muscle Nourishment, stretch Adipose Spaces throughout body Insulation, cushioning

26 Connective Tissue Types
Dense Fibrous Contains elastin Very strong (dense) Slow tissue repair Protection

27 Connective Tissue Type
Location (lining) Function Loose Fibrous Under skin, in muscle Nourishment, stretch Adipose Spaces throughout body Insulation, cushioning Dense Fibrous Ligaments & Tendons Pulling/pushing, forces

28 Connective Tissue Types
Cartilage Partly rigid, partly flexible Elastic(ears) Hyaline(bone ends) Fibro-(backbone) Hyaline

29 Connective Tissue Types
Elastic Cartilage Fibrocartilage

30 Connective Tissue Type
Location (lining) Function Loose Fibrous Under skin, in muscle Nourishment, stretch Adipose Spaces throughout body Insulation, cushioning Dense Fibrous Ligaments & Tendons Pulling/pushing, forces Cartilage Ears, nose, bone ends Cushion, support

31 Connective Tissue Types
Bone Supports organs Attachment point Bone cells are called osteocytes. Well nourished

32 Connective Tissue Type
Location (lining) Function Loose Fibrous Under skin, in muscle Nourishment, stretch Adipose Spaces throughout body Insulation, cushioning Cartilage Ears, nose, bone ends Cushion, support Dense Fibrous Ligaments & Tendons Pulling/pushing, forces Bone Skeleton Support, protection

33 Connective Tissue Types
Blood Red & white blood cells Platelets Plasma Regulates temperature Transportation system

34 Connective Tissue Type
Location (lining) Function Loose Fibrous Under skin, in muscle Nourishment, stretch Adipose Spaces throughout body Insulation, cushioning Cartilage Ears, nose, bone ends Cushion, support Dense Fibrous Ligaments & Tendons Pulling/pushing, forces Bone Skeleton Support, protection Blood Veins, arteries, heart transport

35 Muscle Tissue Cardiac (involuntary) HEART Smooth (involuntary) ORGANS
Skeletal (voluntary) BONES Cardiac Muscle Smooth Muscle Skeletal Muscle

36 Nerve Tissue Found in the brain, spinal cord, and peripheral nerves
Conducts electrochemical impulses Basic cell is called a NEURON

37 What is tissue regeneration?
Tissue can be manmade in a lab Tissues are made from embryoic stem cells Totipotent 500 cell size embryos Research is being done with adult stem cells (taken from bone marrow), but so far is unsuccessful

38 What can tissues do? Help burn victims (epithelial) Repair muscle
Repair organs (heart, liver) Repair nerves/brain/spine Build bone (osteoporosis) Help heal bone ALS, MS, Parkinsons, etc, etc
