The neural organisation is very simple is lower invertebrates iii. Neural system of Hydra is composed of a network of neurons. iv. The neural system is better organised in insects, where a brain is present along with a number of ganglia and neural tissues V. The vertebrates have a more developed neural system . vi. Neural system of earthworm is composed of a network of neurons

The human neural system consists of central neural system (CNS) and peripheral neural system (PNS), how many statements correct for human neural system? i. The CNS includes the brain and the spinal cord ii. The PNS comprises of all the nerves of the body associated with the CNS iii. PNS consist of cranial nerve and spinal nerve iv. The PNS is divided into two divisions called somatic neural system and autonomic neural system v. The efferent nerve fibres of PNS transmit impulses from tissues/organs to the CNS vi. Afferent fibres of PNS transmit regulatory impulses from the CNS to the concerned peripheral tissues/organs.
