4 Primary Tissues

Epithelium, Connective, Muscular, & Nervous

Epithelium Tissues

layers of closely spaced cells that cover organ surfaces form glands, and serve for protection, secretion, and absorption. Inner lining of digestive tract

Connective Tissues

With more matrix than cell volume, often specialized to support and bind together and protect organs

Muscular

Specialized for contraction

3 embryonic germ layers and some adult tissues derived from each

Ectoderm(outer layer), Endoderm(inner layer), and Mesoderm(more loosley organized cells.

Ectoderm

outer layer that gives rise to the epidermis and nerve system

Endoderm

inner layer gives rise to mucsous membrane of the digestive/respiratory tracts

Mesoderm

Loosely organized cells..eventually turns into gelatinous tissues..rise to muscle, bone, bld

8 types of Epithelium

Simple squamous Epithelia, Simple Cubodial Epithelium, Simple Columnar Epithelium,Simple Pseudostratified ,Stratified Squamous Epithelium, Stratifed Cubodial Epithelium,stratified columar epithelium, Transitional

Simple Squamous

flattened cells--lung tissues

Simple Cuboidal

cubodial shape.basement memebrane,liver, thryoid, absorption and secretion production of protective mucous coat

Simple Columnar Epithelium

single layer of tall narrow cells, inner linning of stomach intestines, gallbladder, uterus, and uterine tubes, some kidney tubles,absorption, secretion ofmucus and other products, movement of egg and embryo in uterine tube

Stratified Squamous Epithelium(Keratinized)

Multiple cell layers with cells becoming increasingly flat @ scally toward the surface;surface covered with a layer of ompace dead cells without nuclei, Epidermis, palms and soles are especially heavly keratinized, resists, abrasion, retards water loss through skinn, resists penetration by pathogenies organisms

Stratified Squamous Epithelium(NonKeratinized)

Same as keratinized epithelium but w/0 layer of dead cell. tongue oral mucous, esophagus, anal canal, vagina..

Stratified Cubodial Epithelium

2 or more layers of cells, surface cells square or round, sweat glands ducts, egg-producing vesicles of ovaries, sperm-producing ducts, contributes to sweat secretions, secretions of ovaries, produces sperm

Transistional Epithelium

surface cell are rounded, not flatened and oftern buldge @ surface, urinary tract, bladder, duct in umbilical cord..sretches to allow filing or urinary tract

8 functions of connective tissues

Binding of organs,support, physical protection, immune protection, movement, storage, heat production, transport

Binding organs

tendons bind muscle 2 gone. lingamnets gind 1 bone 2 another, fat holds the kidneys and eyes in place. and fibrous tissue binds the skin 2 musle

Support

bones support the bod and cartilage, supports the ears, nose, trachea, and bronchi

Physical Protection

cranium, ribs, sternum protect delicate orgasn .

Immune Protection

forms a battle field under the skin and mucous membrane where immune cells can be quickly mobilized against diease agents

Movement

provide the lever system for body movement,

Storage

fat is the body's major energy reserve

Heat protection

brown fat generates heat in infants and children

Transport

Blood transport gases, nutrients, wastes, hormones, & bld cells

6 types of cells found in fibrous connective tissues

Fibroblasts, macrophages, leudocytes(wbc), plasma cells, mast cell, adipocytes(fat cell)

Fibroblasts

Large, flat cells that often appear tapered at the ends and show slender, /form matrix of the tissue

Leukocytes(wbc)

travel briefly in the bloodstream, /spend most time in connective tissues

Plasma Cells

certain lymphocytes turn into plasma cells when they detect foreign agents. the plasma cells are rearely seen except in the walls of the intestines and inflammed tissues

adiposytes(fat cells)

large rounded cells filled mainly with a droplet of triglycerides, which forces the nucleus and cystoplasm to occupy only a thin layer jus beneath the plasma membrane.

3 types of tissues found in fibrous connective tissue

Collagenous, Elastic fibers, and Reticular fibers

Collagenous

tough & flexible and resist sretching. collegen is about 25% of the body's protein, the most abudant type. white apperance.as seen in tendons

Elastic fibers

thinner than collagenous fibers,made of protein called elastin, whose recoil like a rubber band.ablitly of the skin, lungs, and arteries to spring back after they are sretched

Reticular fibers

thin collagen fibers cated with glycoprotein. forma a spongelike framework for such organs as the spleen adn lymph nodes

10 types o connective tissues

loose connective , areolar, reticular, adipose, dense regular, dense irregular, elastic,
