Unit 3:Tissues

Tissue

A group of similar cells that perform a specific function.

Epithalamus (pineal gland)

Found in the posterior epithalamus

epithelial tissue

Tissue that covers the outside of the body and lines organs and cavities.

simple columnar epithelium

Made up of a single layer of tall cells that fit closely together

simple squamous epithelium

a single layer of flattened cells

connective tissue

A body tissue that provides support for the body and connects all of its parts

muscle tissues

specialized for contraction, which brings about movement

nervous tissue

A body tissue that carries electrical messages back and forth between the brain and every other part of the body.

mutation

tissue specifically being observed for cancer caused by spontaneous mutations in cells tissue as well as tumors caused by inherited mutations

cancer tissue

The tissue shows uncontrolled growth of cells and abnormal tissue arrangement and cell structure, which do not remain within the original location.

benign neoplasm

noncancerous growths are composed of the same type of cells as the tissue in which they are growing

malignant neoplasm

tumor that invades surrounding tissue and is usually capable of metastasizing (spread to other sites of the body; can be located in any organ or tissue in the body

simple cuboidal epithelium

a single layer of cube-shaped cells

stratified squamous epithelium

Cells arranged in layers around the basal membrane

stratified cuboidal epithelium

rare type of epithelial tissue composed of cuboidal shaped cells arranged in multiple layers.

pseudostratified columnar epithelium

tissue that consists of a single layer of irregularly shaped and sized cells that give the appearance of multiple layers; found in ducts of certain glands and the upper respiratory tract

allows filtering and humidification of incoming air

transitional epithelium

type of stratified epithelium that changes shape in response to stretching (stretchable epithelium). The transitional epithelium usually appears cuboidal when relaxed and squamous when stretched.

glandular epithelium

Composed of cells that are specialized to produce and secrete substances

Neurons (Nervous Tissue) connective tissue

Specialized for sending and receiving information (motor neurons, cortical interneurons).

Bone (Osseous) connective tissue

cells in lacunae (cavities) / Composed of: a hard matrix of calcium salts, and large numbers of collagen fibers / Used to protect and support the body

dense connective tissue

Binds body parts together

areolar connective tissue

soft packing material that cushions that protects body organs

blood connective tissue

fluid extracellular matrix used to transport substances throughout the body.

cardiac muscle tissue

The cardiac muscle is responsible for the contractility of the heart and, therefore, the pumping action

smooth muscle tissue

Involuntary muscle is found in the intestines where it pushes food along the digestive tract. Also found in arteries and veins.

Filtration

Epithelial

fit closely together

Epithelial tissue

Red dots

blood

Insulations

Connective tissue

Blue teal

Cartilage connecting tissue

Specialize in contract or shorten

Muscular tissue

Con system and extracellular matrix

Connetive tissue

Involuntary and voluntary

Muscle tissue

High Vascular

Muscle Tissue

Cartilage connective tissue

A connective tissue that is more flexible than bone and that protects the ends of bones and keeps them from rubbing together and cushions the spaces in your joints where bones meet.

creates electrochemical impulses

Nervous tissue

Nervous and Epithelial tissue

Are Avascular but inverted

Avascular

A- Without Vascular- Blood Vessels

Regulate and control body functions

Nervous tissue

Irritability and conductivity
