Answer to Problem 1CC
Correct answer:
1. Interneuron | (c) Integrating centre |
2. Motor neuron | (b) Efferent signal, (e) output signal |
3. Sensory neuron | (a) afferent neuron, (d) input signal |
Explanation of Solution
1. Interneuron - (c). Integrating centre
Interneuron is present in the spinal cord and is an important part of reflex action. It acts as a connective link between the motor neuron and the sensory neuron and hence it is called as integrating centre of the reflex arc.
2. Motor neuron - (b), (e). Efferent signal, output signal
Motor .neuron is the set of neuron that conduct signal called as output signal from the brain to the target muscles. The neurons are also called as efferent neurons and the signal is called as the efferent signal.
3. Sensory neuron - (a), (d). Afferent neuron, input signal
Sensory neuron is the set of neuron that conducts signal called as input signal from the sensory receptors to the processing unit of the CNS such as brain or spinal cord. The neurons are also called as afferent neurons and the signal is called as the afferent signal.
