Topics covered in Structural Organisation in Animals for CUET (UG) Biology.

Topics in Structural Organisation in Animals

1

Basic Concepts and Tissue Types

  • In unicellular organisms, all functions are performed by a single cell, while in multicellular organisms, specialized groups of cells perform specific functions
  • A tissue is a group of similar cells with intercellular substances having similar origin and performing a specific function
  • All complex animals have only four basic tissue types: Epithelial, Connective, Muscular, and Neural
2

Epithelial Tissue

  • Epithelial tissue has a free surface facing body fluid or external environment
  • Cells are compactly packed with little intercellular matrix
  • Simple epithelium: single layer - Squamous (diffusion), Cuboidal (secretion/absorption), Columnar (protection/secretion)
3

Connective Tissue

  • Most abundant and widely distributed tissue; connects and supports other tissues
  • Contains cells, fibers (collagen/elastin), and matrix between cells and fibers
  • Loose connective tissue: cells and fibers loosely arranged in semi-fluid ground substance
4

Muscular and Neural Tissue

  • Muscular tissue contains contractile fibers (myofibrils) in cytoplasm (sarcoplasm)
  • Skeletal muscle: striated, voluntary, attached to bones, bundles in connective tissue sheath
  • Smooth muscle: non-striated, involuntary, spindle-shaped, found in internal organs
