Types of Tissues

Areolar

Wraps and cushions organs; its phagocytes engulf bacteria; plays important role in inflammation; holds and conveys tissue fluid

Stratified Squamous

Protects underlying tissues in areas subjected to abrasion

Pseudostratified

Secretion, particularly of mucus; propulsion of mucus by ciliary action

Simple Cuboidal

Secretion and absorption

Transitional

Stretches readily and permits distension of urinary organ by contained urine

Simple Columnar

Absorption; secretion of mucus, enzymes, and other substances; ciliated type propels mucus by ciliary action

Adipose

Provides reserve food fuel; insulates against heat loss; supports and protects organs

Reticular

fibers form soft internal skeleton (stroma) that supports other cell types

Four Types Of Tissue

Connective, Muscular, Epithelial, Nervous

Dense Connective

Attaches muscles to bones or muscles; attaches bones to bones; withstands great ensile stress when pulling forces is applied in one direction

Hyaline Cartilage

Supports and reinforces; has cushioning properties; resists compression

Skeletal

Voluntary movement; has striations

Nervous

Transmits electrical signals from sensory receptors and to effectors (muscle and glands) which control the activity

Smooth

Involuntary; no striations

Cardiac

Involuntary movement; has striations and intercalated discs

Simple Squamous

Allows passage of materials by diffusion and filtration in sites where protection is not important; may secrete lubrication substances

Bone (Osseous Tissue)

Supports and protects; provides levers for the muscles to act on; stores calcium and other minerals and fat; marrow inside bones is the site for blood cell formation (hematopoiesis)
