Assertion : The chemical stored in the synaptic vesicles are termed as neurotransmitters.
Reason : Synaptic vesicles release these chemicals in the synaptic cleft.
Assertion : Nerve impulse can never be transmitted from dendrite or cell body of one neuron to the axon of the next neuron, across a synapse.
Reason : This happens because of the synaptic delay at each synapse.
Assertion : Nerve conduction is the one way conduction.
Reason : Nerve impulse is transmitted from dendrite terminals to axon terminals.
Assertion : After hearing a sound, nerve impulse passes from neurons to the brain.
Reason : The neurons which pass nerve impulses from the body organ to the brain is called afferent neuron.
Assertion : Cerebrospinal fluid is present throughout the central nervous system.
Reason : CSF has no such function.
Assertion : A person has lost most of its intelligence, memory and judgement.
Reason : A person has operated a tumour located in the cerebrum.
Assertion : Some areas of the brain and spinal cord look white.
Reason : This is because cell bodies of neurons are situated in those areas.
Assertion : Motor neuron terminates on a motor end plate at the neuromuscular junction.
Reason : Motor end plate acts as receptor for detecting changes in the muscle fibres.
Assertion : The brain stem contains centres for controlling activities.
Reason : Brain stem is very sensitive.
Assertion : Spinal cord has a column of both grey and white matter.
Reason : Grey matter forms the central spinal canal.
