Answer 2

Cell transmits impulses from (C) receptor cells to spinal cord.

Explanation:

• Changes inside and outside the body are detected and responded to by the neurological system.
• Receptors are structures at the terminals of nerve fibres that detect and convert environmental changes (stimuli) into electrical impulses. Specialized sense organs such as the ear, eye and skin could be the receptors.
• Electrical signals (impulses) from receptors or sense organs are carried to the CNS (Central Nervous System) by sensory neurons. Afferent neurons are another name for them.
• The brain and spinal cord make up the central nervous system. Motor neurons transport CNS impulses to effector organs. Efferent neurons are another name for them.
• Muscles or glands that act in response to the motor neurons stimulation are known as effectors.
• Hence the correct sequence is: Receptor→Sensory Neuron→Spinal cord→Motor neuron→Effector
