The Pathway carries information on pain, temperature, deep pressure, and coarser aspects of the sense of touch stimuli that we are aware of but cannot localize precisely.

The somatosensory pathway.

Explanation:

The somatosensory pathway is a sensory pathway that carries the perceptions of pain, temperature, touch and pressure. The neurons of the somatosensory pathway are distributed throughout the body. The pathway has sensory receptors in the skin, muscles and organs.

The somatosensory pathway typically has three neurons which are the primary neurons, secondary neurons and tertiary neurons.

The primary neurons carry sensory stimuli like touch and temperature from the receptors in the skin to the spinal cord. The secondary neurons convey these stimuli, specifically through the spinothalamic neurons to the thalamus and brainstem.

The tertiary neurons then take up these stimuli to the cerebral cortex.

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.
