Connective tissueMajor types of connective tissue:

Areolar

Adipose

Fibrous connective

Bone

Cartilage

Blood

Hemopoietic

Areolar tissuemost widely distributed, gives form to organs, consists of webs of fibers

Blood tissuematrix is liquid, used in transport, protection

Blood smear

Bonematrix is hard and calcified, circular arrangement of cells called

osteons, storage for calcium, provides support and protection

Dense fibrous tissueconsists of bundles of strong collagen fibers, composes tendons,

anchors muscles to bones

Cartilage tissuesmatrix is consistency of firm plastic, cells called chondrocytes

Adipose tissuefat tissue, store lipids

Hemopoietic Tissuefound in red marrow cavities of bones, spleen, tonsils and lymph nodes

involved in formation of blood cells

Muscle tissue

• 3 kinds: skeletal, cardiac and smooth

Skeletal muscle tissue“Striated”, voluntary, attaches to bone

Cardiac Muscle tissueInvoluntary, intercalated disks, walls of heart

Smooth muscle (Visceral)involuntary, walls of blood vessels and hollow organs

Nervous tissue - communication

• Composed of cell body, axon and dendrites
