Name the 4 tissue types

Epithelium, connective, muscle, nervous

Epithelium tissue characteristics

• linings, coverings, glandular tissue

• tightly packed continuous sheets

• ex. outer layer of skin, stomach lining, air sacks in lungs

Connective tissue characteristics

• protects, supports, binds

• cells integrated into a non living matrix

• ex. bones, cartilage, fat, blood, ligaments, tendons

Muscle tissue characteristics

• contracts and causes movements

• skeletal- attached to skeleton, movement, voluntary

• smooth- digestive tract, pushes liquids/objects through body, involuntary

• cardiac- heart, squeezes heart/pumps, involuntary

Nervous tissue characteristics

• composed of neurons

• sends and receives signals in body

• ex. brain, spinal cord, nerves

Epithelium tissue

Connective tissue

Muscle Tissue

Nervous tissue

Osteon

columns of bone tissue

central canal/ haverisian canal

longitudinal canal that contains blood vessels, carrying blood to and from the osteon

lamella

layers of matrix around the central canal

lacuna

site of osteocytes

osteocytes

mature bones, scattered throughout lamella

canaliculi

narrow passageways connecting osteocytes

Compact Bone

Spongy Bone

epiphyses

ends of long bone, contain spongy bone and red bone marrow

diaphysis

middle of long bone, contains medullary cavity and yellow bone marrow

compact bone

located around perimeter of long bone, surrounds medullary cavity

periosteum

covers entire long bone, allows blood and nutrients to enter

metaphysis

neck portion of long bone

irregular bones

maxilla, mandible, sacrum, hip bones

short bones

carpals, tarsals

long bones

humerus, femur, tibia

flat bones

parietal bones, sternum, shoulder blades, ribs
