  1. WORM VOCAB ONLY

  2. Seta (Setae) One of the external bristles on annelids ______________ A pair of nerve clusters that serve as a brain at the anterior end of some invertebrates _________________ A thickened section around an earthworm’s body that ______________ produces mucous for reproduction Cerebral ganglia clitellum

  3. Flame cell In a flatworm, a cell that collects excess body water and transfers it to the excretory system ______________ An organism that produces both male and female gametes (sperm & eggs _________________ An infolding of the intestinal wall of an earthworm that increases surface area to absorb more nutrients ________________ hermaphrodite typhlosole

  4. prostomium Fleshy flap of skin that overhangs and protects the mouth of an earthworm ________________ A NON-CELLULAR LAYER in parasitic round worms that protects them from the host’s digestive and immune system (also seen in earthworms)_________________ A structure in a female or hermaphrodite that receives sperm ________________ cuticle Seminal receptacle

  5. tegument A continuous sheet of FUSED CELLS that covers the external surface of a fluke or tapeworm & protects the worm from the host’s digestive and immune system __________________ Tubule through which some invertebrates (like segmented and round worms) eliminated nitrogen waste _________________ A thick wall that divides an organ ________________ nephridia septum

  6. pharynx In a flatworm, a muscular tube that leads to the gastrovascular cavity; in animals with a digestive tract, the part of the tract between the mouth and esophagus ______________ 5 pair of muscular tubes which connect the corsal and ventral blood vessels and force blood through the circulatory system ________________ A knob shaped organ bearing hooks and suckers that lies at the anterior end of a tapeworm ________________ Aortic arches scolex

  7. proglottid One of the many body segments of a tapeworm containing reproductive organs ______________ The structure that stores soil waiting to be digested in earthworms _________________ A muscular region in the digestive tract of earthworms that crushes and grinds food ________________ crop gizzard

  8. Intermediate host The host from which the larvae of a parasitic worm derive their nourishment ______________ A disease characterized by muscle pain and stiffness caused by a parasitic blood fluke of the genus Schistosoma _________________ A carbohydrate found in the cocoons of earthworms and the exoskeletons of some arthropods ________________ schistosomiasis chitin
