13808.	Question : Neural system and computers share certain common features. Comment in five lines. (Hint - CPU, Input - Output devices).
Answer» Solution :Sensory NEURONS are present in various organs of the body. They receive stimuli from the environment and send it to brain. So it works like input device of computer. Brain ACTS as CPU (Central Processing Unit). INFORMATIONS collected from sensory neurons are analysed in the brain and instructions relayed to various organs accordingly. Such messages are transmitted through motor nerve, which serves as OUTPUT device.

Answer» SOLUTION :DENDRITES,AXON

Discussion

13815.	Question : Nerve impulses are conducted more rapidly in myelinatedfibres than in non-myelinated fibres.
Answer» Solution :The PRESENCE of a myelin sheath in myelinated fibres increases the velocity of conduction and also reduces the energy expended in the process of conduction. In myelinated fibres, the conduction takes place by JUMPING of the action potential from one NODE of Ranvier to another, instead of TRAVELLING along the NERVE membraneas in a non-myelinated fibre.

Discussion

13816.	Question : Nerve fibres transmit the nerve message by _____means.
Answer» chemical physical electrochemical ELECTRICAL Solution :Due to a gap of 200Å in between two NEURONS, the electrical transmission of nerve impulse is not possible because the post-synaptic membrane cannot be depolarised WITHOUT the aid of NEUROTRANSMITTERS (chemicals).Hence, in this way, the transmission of nerve impulse is an electrochemical INCIDENCE.
