FOUR TYPES OF ANIMAL TISSUES
EPITHELIAL TISSUE (COVERING) Tightlyjoined closelypacked cells One side of exposed to air or internal fluid, other side attached to a basement membrane Covers outside of the body and lines internal organs and cavities Barrier against mechanical injury, invasive microorganisms, and fluid loss Provides surface for absorption, excretion and transport of molecules
TYPES OF EPITHELIAL TISSUE Cell shape Squamous Cuboidal Columnar Number of cell layers Simple Pseudostratified Stratified RELATE STRUCTURE TO FUNCTION!
CONNECTIVE TISSUE (FRAMEWORK) Binding and support of other tissues Large amount of extracellular matrix with fewer cells ECM network of fibers in liquid, jellylike or solid matrix
MUSCLE TISSUE Composed of long cells called muscle fibers (MOVEMENT) Contraction movement
NERVOUS TISSUE (CONTROL) Senses stimuli and transmits Axon nerve impulses Dendrite Single cell Cell body body with long extensions (axons and dendrites)
Tissue Type Epithelial Connective Muscle Nerve Cell Shape Flattened, Irregular or round Elongated Cell appendages cuboidal, branched columnar Cell Single Scattered in In sheets or Isolated or Arrangement multilayered matrix bundles networked Location Body covering or Supports other Lining internal Concentrated in lining organs or organs organs, make brain and spinal cavities skeletal muscles cord + all over the body Surface Feature Cilia, microvilli - - - of Cells Matrix Type Basement Varied – protein - - membrane fibers + liquid, gelatinous, firm to calcified Matrix Amount Minimal Extensive Absent Absent Unique Feature No direct blood Cartilage has no Can generate Can generate supply, except for blood supply electrical signals, electrical signal glands force and movement
