Types of Tissues

Four Types Of Tissue

Connective, Muscular, Epithelial, Nervous

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

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)
