The
earthworm dissection model, with its large size and vibrant anatomy, is an
excellent tool for studying the structure and function of earthworms. Key
anatomical parts, such as the mouth, buccal cavity, pharynx, spermathecae,
aortic arches, esophagus, crop, gizzard, intestine, dorsal blood vessel, setae,
cuticle, lymph gland, ventral nerve cord, accessory gland, common spermatic
duct, prostate gland, vas deferens, ovary, oviduct funnel, testes, and seminal
vesicle, can be observed in detail. This model offers a visually and
kinesthetically effective approach to understanding earthworm anatomy.
