NEMA 503 STRUCTURAL AND FUNCTIONAL ORGANIZATION OF NEMATODES                                                                                 (2L+2P) I

Objective
  Familiarization with morphology, anatomy, histology, ultra-structure and functions of various organs and systems to enable the students to understand biology, physiology, evolutionary trends and classification of nematodes.

Theory

UNIT I
  Introduction and general organization of nematode body; Morphology and anatomy of nematode cuticle, hypodermis, musculature and pseudocoelom.

UNIT II
  Digestive system- structural variations of stoma, oesophagus, intestine and rectum in nematodes.

UNIT III
  Reproductive system- Variations in female and male reproductive systems, types of reproduction, spermatogenesis and oogenesis

UNIT IV
  Types and structure of excretory-secretory systems; nervous system and associated sense organs.

UNIT V
  Embryogenesis, Cell lineage and postembryonic development; Process of hatching and moulting.

Practicals
  Studies on variations in nematode shapes and sizes, morphological details of cuticle, cuticular markings and ornamentation, variations in stoma, oesophagus, rectum; types and parts of female and male reproductive systems, sense organs, and excretory system.
