Nematode Nervous System Overview, Anatomy
The ventral nerve cord is a major structure of the invertebrate central nervous system. It is the functional equivalent of the vertebrate spinal cord. The ventral nerve cord coordinates neural signaling from the brain to the body and vice versa, integrating sensory input and locomotor output. Because arthropods have an open circulatory system,decapitated insects can still walk, groom, and mate - illustrating that the circuitry of the ventral nerve cord is sufficient to perform c… WebThe ventral nerve cord, connected to the brain by the circumesophageal connectives, is composed of a double row of ganglia connected longitudinally by connectives and … Conditions or injuries that may affect the basal ganglia include: 1. Head trauma 2. Brain tumors 3. Infection 4. Poisoning 5. Drug overdose 6. Stroke 7.
