 इस मडउल में हम खलास एरिकश नीट्ट के नरहवास्टदम को दिसक्स करेंगे नरहवास यस्तम कि पाकी आरख़ृपोदः की तरा एरिक नीट्ट स में भी ब॓डी की विनट्रल साइट पोईप्क़ा और इस को हम कहती है, विंट्रल नहवास्सिस्तम यप के अंचश्ट्रल आर्ट्रो पोड़द किटे इंका नवबस्ट्रम अगर लगा मेंगाई मिलता जुलता है. आप स्कोर्पियान्स के लगा नवबस्ट्रम और नवबस्ट्रम जोके आरिक नीट्स का है, this is in the form of thick and nerve masses which we will call ganglions now like other orthropods of the central nervous system there will be a ventral solid nerve cord and along with this series of fused ganglions they are associated with various body segments i.e each segment will have a respective paired ganglion cerebral ganglion which we will call brain this gives rise to the nerves to the eyes and to the calicera then inside this is epistosomal ganglion epistosomal ganglion which is this inner weights the walking legs now nervous system, brain, nerve cord, ganglia, specialized nerve cells in this diagram you will see that ganglion which is present in the head region we will call them cerebral ganglion now cerebral ganglions they will behave like brain and like their brain they will control the different parts of the body apart from this in different body segments there will be thick and nerve masses or each segment will have its own ganglion now the cerebral ganglion each ganglion will have its own nerve cord now this is the cerebral ganglion from cerebral ganglion this nerve cord this is arising and it is passing throughout the body similarly each ganglion will have its own nerve cord and it will run throughout the body now in this ganglions there will be thoracic ganglions abdominal ganglions pharyngeal ganglions in every segment the organ of the body will have its own ganglion now nerve cord if there is one ganglion this will be single some ganglions will be smaller and the two smaller ganglions they are also connected with one another whatever they connect we will call them commissure now the nervous system in case of Eric Nitz it consists of brain nerve cords ganglion and specialized sensory organs like antenna
