epithelial membranes

__ composed of epithelial and connective tissues and covers body surfaces and lines cavities

serous, mucus, and cutaneous

What are the 3 types of epithelial membranes known as:

serous membranes

line the body cavities that do not open to the outside of the body (cover organs)

thorax and abdomen

serous membranes line the inner portions of the __

simple squamous epithelium + areolar connective tissue

serous membranes are known as __ (more superficial)

serous fluid

serous membranes secrete __ for lubrication, reducing friction between organs and cavity walls

mucus membranes

lines, cavities, and tubes that open to the outside of the body

digestive, respiratory, urinary, and reproductive tracts

mucus membranes line the __

epithelium + areolar connective tissue

mucus membranes consists of __

goblet cells

__ secrete mucus

cutaneous membranes

__ covers the body surface commonly known as skin

protective barrier

Cutaneous membranes are __ against physical damage, water loss, and pathogens

synovial membranes

__ are different from epithelial membranes and are composed entirely of connective tissues

joint cavities

synovial membranes line __

synovial fluid

cells secrete __

muscle tissue

responds to stimulation and elongates the cells by contracting and thickening

muscle fibers

elongated cell are known as __

fibers pull ends

stimulation —> __ —> movement

skeletal muscle tissue

voluntary

multi-nucleated

striated with alternating light and dark bands

naked eye

Skeletal muscle tissues are long, cylindrical, and __`

nerve cells

skeletal muscle tissues are stimulated by __ to contract when movement is needed

smooth muscle tissue

non-striated

involuntary

spindle-shaped fibers that are shorter than skeletal muscle tissue because it allow them to contract and elongate

single nucleus

hollow organs and blood vessels

smooth muscle tissues have walls of __ the move food through the digestive tract; arteries contract to move blood

cardiac muscle tissue 

striated cells

junctions are intercalated discs

involuntary

in the heart

cardiac muscle tissue is only found __

nervous tissue

found in the brain, spinal cord, and peripheral nerves

neurons

Basic cells of the nervous tissue are highly specialized cells that coordinate, regulate, and integrate many body functions

neuroglia

cells that support and nourish neurons & “nerve clue”

oligodendrocytes

astrocytes

microglia

do not

neuroglia (do/do not) produce electrical impulses

phagocytosis

neuroglia support bind, carry on __, provide nutrients and communicate
