four types of tissue

Most of the organisms you are familiar with – including yourself

New properties arise with each step upward the hierarchy of life. These are called

covers and lines body cavities both inside and outside of the body.

Protects and insulates vital organs and fills body cavity spaces. Connects different type of tissues to each other.

Functions in locomotiondigestive and cardiovascular functions.

Communicate electrical impulses which facilitates the action of both muscles and glands

Epithelial Tissues Location and function

This type of tissue is commonly seen outside the body as coverings or as linings of organs and cavities. Epithelial tissues are characterized by closely-joined cells with tight junctions (i.e., a type of cell modification).

Being tightly packed, __________ serve as barriers for pathogens, mechanical injuries, and fluid loss.

Cells that make up epithelial tissues can have distinct arrangements:

is a rare type of epithelial tissue composed of column shaped cells arranged in multiple layers.

are found in the conjunctiva of the eye, in parts of the pharynx, anus, the uterus, and the male urethra and vas deferens.

for secretion

brick-shaped cells; for secretion and active absorption

plate-like cells; for exchange of material through diffusion

multilayered and regenerates quickly; for protection

singled layer of cells; may just look stacked because of varying height; for lining of respiratory tract; usually lined with cilia (i.e., a type of cell

cells stretch readily in order to accommodate fluctuation of volume of the liquid in an organ.

made up of loose connective tissue that is found in the skin and fibrous connective tissue that is made up of collagenous fibers found in tendons and ligaments.

tissues that store fats which functions to insulate the body and store energy.

characterized by collagenous fibers embedded in chondroitin sulfate.

are the cells that secrete collagen and chondroitin sulfate.

mineralized connective tissue made by bone-forming cells called osteoblasts which deposit collagen.

Bone mineralized connective tissue made by bone-forming cells called _______ which deposit collagen.

type of muscle tissues

These tissues are composed of long cells called _______ that allow the body to move voluntary or involuntary.

These tissues are composed of long cells called muscle fibers that allow the body to move voluntary or involuntary.

striated; voluntary movements

striated with intercalated disk for synchronized heart contraction; involuntary

These tissues are composed of nerve cells called neurons and glial cells that function as support cells. These neurons sense stimuli and transmit electrical signals throughout the animal body.

These tissues are composed of nerve cells called _____ and _____ that function as support cells.

is the part of the neuron that receives impulses from other neurons

is the part where the impulse is transmitted to other neurons.
