The neuron which carries nerve impulses from receptors to spinal cord is called sensory neuron.

Q. Question 5

(b) Receptors→ Motor neuron → Spinal cord → Sensory neuron → Muscle
(c) Receptors → Spinal cord → Sensory neuron → Motor neuron → Muscle
(d) Receptors → Sensory neuron → Spinal cord → Motor neuron → Muscle

Q. One of the following gives the correct sequence of the components in a reflex arc. This is :
(a) Receptors → Muscle → Sensory neuron → Motor neuron → Spinal cord
(b) Receptors → Motor neuron → Spinal cord → Sensory neuron → Muscle
(c) Receptors → Spinal cord → Sensory neuron → Motor neuron → Muscle
(d) Receptors → Sensory neuron → Spinal cord → Motor neuron → Muscle

Q. Which of the following statements are true?
(i) Sudden reaction in response to the stimulus is called reflex action.
(ii) Sensory neurons carry signals from the spinal cord to muscles.
(iii) Motor neurons carry signals from receptors to spinal cord.
(iv) Reflex arc is the process in which the nerve impulse is carried and the response is generated.
