Tissue types

A tissue is a group of cells, in close proximity, organized to perform one or more specific functions.

There are four basic tissue types defined by their morphology and function: epithelial tissue, connective tissue, muscle tissue, and nervous tissue.

  • Epithelial tissue creates protective boundaries and is involved in the diffusion of ions and molecules.
  • Connective tissue underlies and supports other tissue types.
  • Muscle tissue contracts to initiate movement in the body.
  • Nervous tissue transmits and integrates information through the central and peripheral nervous systems.

 

Key facts about the tissue types
Epithelial Tissue Features – high cellularity, special sensory receptors, forms a barrier, avascular, innervated

Surfaces – basal (hemidesmosomes, basement membrane), apical (lumen, microvilli, cilia, stereocilia), lateral (adhering junctions, tight junctions, desmosomes, gap junctions)

Types – squamous, cuboidal, columnar, simple, stratified, pseudostratified, specialized

Connective Tissue Structure – cells (structural, immunological, defense, energy reservoirs), extracellular matrix (ground substance, protein fibers)

Types of fibers – collagen, reticular, elastic

Classification – proper (dense, loose), embryonic (mesenchyme, mucous), specialized (cartilage, adipose, bone, blood)

Muscle Tissue Features – elastic, extensible, contractile

Types – skeletal, cardiac (gap junctions, intercalated discs), smooth, striated, nonstriated

Nervous Tissue Neurons – soma, dendrites, axons, ganglia (PNS), nuclei (CNS)

Glia – astrocytes, oligodendrocytes, Schwann cells, microglia – blood-brain barrier
