1 X-Inter neuron, Y-Cell body of motor neuron
2 X-Cell body of motor neuron, Y-Dorsal root ganglion
3 X-Inter neuron, Y-sensory neuron
4 X-Inter neuron, Y-Dorsal root ganglion
Explanation:
B Motor neurons are nerve cell responsible for transmitting signal from the central nervous system (brain and spinal cord) to the muscles and glands enabling movement and physiological responses. The dorsal root ganglion is a cluster of sensory along nerve cell bodies located along the dorsal root of each spinal nerve. It contain cell bodies of sensory neurons that transmit signal from the body's periphery (skin, muscles, organs) to the spinal cord and brain.

3 sense organ, motor neuron, spinal cord, sensory neuron, muscles
4 sense organ, motor neuron, spinal cord, sensory neuron, muscle
Explanation:
B When a sensory receptor is stimulated signals pass from it through a sensory neuron to the spinal cord. The message travels out of the spinal cord along a motor neuron to the effectors organ (e.g. a muscle or a gland) which acts accordingly. Such a pathway is called a reflex arc.

Sensory receptor of warmth located principally at the tip of fingers is known as:
1 Weber's organ
2 Organ of Giraldes
3 Ruffini's corpuscles
4 Organ of Zuckerkandl
Explanation:
C Ruffini's corpuscles are slowly adapting lowthreshold mechanoreceptors that are found in the dermis of the skin. They are responsible for perception of warmth and pressure. They are most abundant in the fingertips, palms, soles of the feet and lips.
