Animal tissues form the structural foundation of all human organ systems. This comprehensive guide covers the four primary tissue types – epithelial, connective, muscular, and nervous – with clinical correlations for medical students:
- Epithelial Tissue: Classification of simple/pseudostratified epithelia (squamous, cuboidal, columnar) by location (skin, alveoli, intestines) and functions like barrier protection, absorption, and mucus secretion .
- Connective Tissue: Analysis of extracellular matrix components, including loose/dense connective tissues, specialized forms (blood, bone, cartilage), and adipose tissue roles in energy storage .
- Muscle Tissue: Comparison of striated (skeletal, cardiac) vs. smooth muscle ultrastructure, contraction mechanisms, and location-specific functions .
- Nervous Tissue: Neuron-glia interactions, signal transmission pathways, and sensory receptor biology .
Includes high-yield exam content: histological identification tips, tissue-specific diseases, and NCERT-aligned diagrams (Chapter 7: Structural Organisation in Animals) . Free PDF download contains summary tables, concept maps, and practice questions for NEET/AIIMS preparation.
