If you touch a hot stove, sensory receptors in your fingertip sense the dangerous heat and convert this stimulus into an electrical signal. This signal leaves your fingertip via nerve cells called SENSORY NEURONS (AFFERENT NEURONS). These nerves are part of an anatomical division of the nervous system called the PERIPHERAL NERVOUS SYSTEM. The signal travels along these nerves, and then to the spinal cord and brain. These two structures make up an anatomical division called the CENTRAL NERVOUS SYSTEM . Within this part of the nervous system, specialized nerves called INTERNEURONS integrate this information, formulate a response, and then communicate these instructions as nerve impulses to MOTOR NEURONS (EFFERENT NEURONS) . These neurons bring the message to the muscles in your arm to pull your hand away.

Explanation:

Receptor is the first component of the sensory pathway with the function to receive signal (it detects the change in environment, external or internal). Sensory neuron is responsible for the transport of signal from the receptor to the interneurons  which is then connected with the motor neuron.Motor neuron further sends the signal to the effector which produces the response (e.g. muscle contraction).

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
