Assertion:This PNS comprises of all the nerves of the body associated with CNS.
Reason:PNS is the site of information processing and control.

Which of the following is known as the site of information processing and control?

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.

All the nerves of the body associated with the CNS (brain and spinal cord), comprised in

Site whre all the information are processed & controlled is

Read the following statements (A – D) : (A) The nerve fibres of PNS are two types afferent and efferent fibres (B) PNS comprises of all nerves of body associated with the brain only. (C) Efferent fibres transmit regulatory impulses from CNS to pheripheral tissues. (D) Brain, ganglia and neural tissues found in neural system of insecta. How many of above statements are right?

Site where all the information are processed & controlled is___________.

Assertion:Reflex arc comprises of at least one afferent neuron, one efferent neuron and a part of PNS. Reason:The efferent neuron receivers signal from a sensory organ and transmits the impulse via a ventral nerve root into the PNS.
