Tissue
integrated group of cells working together
Muscle tissue
movement (smooth, skeletal, cardiac)
Smooth muscle
not striated, involuntary (internal organs)
Skeletal muscle
striated, voluntary
Cardiac muscle
striated, involuntary (heart)
Connective tissue
connections (cells imbedded in extra-cellular matrix)
Loose connective tissue
cells & fibers embedded in semifluid matrix
Areolar tissue
internal cushioning
Fibrous connective tissue
collagen fibers matrix arranged in bundles
Tendon connects___
muscle to bone
Ligament connects ____
bone to bone
Adipose
apidocytes store triglycerides (fat cells)
Blood
blood cells in a liquid matrix (plasma)
Cartilage
chondrocytes in a collagen matrix
Bone
osteocytes in calcified collagen matrix
Nervous tissue
relay information

covering
Simple
one layer of cells
Stratified

Squamous
flat shape
Cuboidal
square
Columnar
tall rectangle
Organ
part of body that performs a specific function
Organ system
set of cooperating organs
Integumentary system
protective outer layer (skin, fat, nails)
Muscular system
muscles for movement
Skeletal system
internal support structure (Bone, cartilage, ligaments, tendons)
Circulatory system
pumps blood throughout body
Endocrine system
broadcast signaling, hormones
Nervous system
point to point signaling, nerve impulse (Brain, spinal cord, nerve fibers)
