Tissue

Group of cells that usually have a common origin and function together to carry out specialized actuviries

Histology

Study of tissues

Pathologist

A physician who examines cells and tissues to help other physicians make accurate diagnosis

4 types of body tissue

Epithelial


Connective


Muscular


Nervous

3 characteristics of epithelial tissue

1. Covers body surfaces lines hollow organs body cavities and ducts


2.forms glands


3. Allows body to interact with both its internal and external environments

3 characteristics of connective tissue

1. Supports and protects


2. Binds organs together


3. Stores energy reserves as fat

Function of muscle tissue

Has the ability to contract to produce movement

Function of Nervous tissue

Generates an action potential or nerve impulse that activates glandular secretions and muscular contractions

9 features of epithelial tissue

Closely packed cells


Arranged in sheets


Sits on basement membrane


Plentiful cell junctions


Surfaces


Avascular


Has a nerve supply


High mitotic rate


Protection, filtration, secretion and absorption are the function


Function of simple cells

Diffusion, osmosis filtration secretion and absorption

Function of stratified cells

Protection

Function of pseudostratified cells

Secretion. May have cilia or goblet cells

Function of squamous cells

Rapid movement of substances

Function of Cuboidal cells

Secretion and absorption

Function of columnar cells

Secretion or absorption. May have cilia or microvili

Where are simple squamous cells found?

Sites of filtration; lungs and kidneys

Where are simple cuboidal cells found

Ovaries lines kidneys small ducts and many glands. Makes up secreting portion of some glands

Where are nonciliated columnar cells found (contains goblet cells or microvili)

Gastrointestinal and gallbladder

Where are ciliated simple columnar cells found?

Falopian tubes and some bronchials of the respiratory tract

Where are pseudostratified columnar cells found

Secretes mucus that traps particles in the respiratory tract

Where are keratinized stratified squamous cells found?

Superficial layers of the skin

Where are nonkeratinized stratified squamous cells found

Areas that want to retain moisture. Vagina mouth esophagus

Where are stratified cuboidal cells found

Rare. Found in adult sweat glands

Where are stratified columnar cells found

Protection and secretion. Found in urethra and ducts of some glands

How do transitional cells change in the bladder or urethra

Stratified cuboidal —-> stratified squamous

How do holocrine glands function

Cells ruptures in the process of secreting product. (Oil goands)

How do merocrine glands function

Most common gland. Works through exocytosis. (salivary, pancreas)

How do apocrine glands work

Product is made within the cell and pinched off and secreted (mammary glands)

Function of connective tissue

Supports and protects

5 features of connective tissue

1. Widely spaced cells with a lot of variety that float in abundant extracellular matrix


2. Does not usually occur on free surfaces


3. Has a nerve supply except cartilage


4. Has a rich blood supply except for cartilage and tendons


5. Matrix may be fluid semi fluid or calcified. Matrix is created by connective tissue

What is the most common cell found in connective tissue

Fibroblasts

Function of collagen fibers

Strength and elasticity

Elastic fibers function

Creates elasticity that allows tissue to be stretched up to 150%

Reticular fiber function

Branching. Creates stroma that supports soft organs

Macrophage function

Phagocytosis. Type of white blood cell

Plasma cell function

Develop from lymphocytes and create antibodies. Found in nonkeratinized tissue

Mast cells function

Release histomine and tend to tissue damage. Most abundant in red blood cells

Where does connective tissue develop from

Mesenchyme

Areolar loose connective tissue function

Forms subcutaneous layer that attaches skin to underlying tissues and organs

Function of reticular loose connective tissue

Forms stroma that supportssoft organs

Function of dense regular connective tissue

Designed for pulling in 1 direction. Found in tendons and ligaments and mainly made of collagen

Function of dense irregular connective tissue

Withstands pulling in many directions. (Heart valves pericardium)

Dense connective elastic tissue function

Stretch. (Lungs, arteries trachea)

How does cartilage form

Chondroblasts lay the matrix then mature into chondrocytes

What is the most abundant cartilage

Hyaline. Found where long bones meet bone. (Larynx, nose and knee)

What is the strongest cartilage and where is it found

Fibrocartilage. Veryebral discs and miniscus (pads between bones)

Where is elastic cartilage found and what is its function

Strength and elasticity. External upper ear.

What is the difference between tendons and ligaments

Tendons attach muscle to bone ligaments attach bone to bone

What is the difference between an osteon and trabeculae

Osteon is found in compact bone trabeculae is found in spongy bone

Features of skeletal muscle

Multinucleated striated and voluntary

Features of cardiac muscle

Striated and involuntary

Features of smooth muscle

Involuntary and non striated. Spindle shaped cells found in arteries gastrointestinal tract and uterus. Function is motion

What is the difference between neurons and neuroglia

Neurons generate the nerve impulse neuroglia support neurons

6 functions of the skin

1. Thermoregulation


2. Blood reservoir 8-10% of blood is moving through skin


3. Protection


4. Sensations


5. Excretion and absorption


6. Synthesis of vitamin d

What compound is formed from vitamin d synthesis

Calcitriol

What is the name of the receptor that detects pressure in the skin
