5.1.1 Morphology
Generally, (human) tissue is composed of cell compounds which serve common
functions and tasks in the body. Tissue assemblies organize to organs supplied by
nerves and vessels in a framework of connective tissue (Thews 1999). From a
morphologic and functional point of view, four main tissue groups are distin-
guished: epithelial, connective, muscle and nervous tissue. Epithelial tissue covers
the inner and outer surfaces of the body and carries out secretory (glandular
epithelium), resorption (resorptive-epithelium) or sensory (sensory epithelium)
functions, cf. Fig.

mesenchyme and gelatinous tissue, reticular tissue, cf. Fig.

subdivided into chorda and cartilage-tissue, bone tissue, cf. Fig.
