Digestion is a necessary part of the absorption process. Food first enters the stomach after you chew and swallow it. The stomach stores the food and liquid you swallow and mixes it with digestive juices that the stomach makes.
Processing primarily occurs in the primary somatosensory area in the parietal lobe of the cerebral cortex: information is sent from the receptors via sensory nerves, through tracts in the spinal cord and finally into the brain.he sensory information (touch, pain, temperature etc.,) is then conveyed to the central nervous system by afferent neurons. There are a number of different types of afferent neurons that vary in their size, structure and properties.
Previous chapters described the ways in which the different somatosensory receptors respond to specific types of somatosensory stimuli and that the receptors, by virtue of their selective sensitivities, extract specific information about the somatosensory stimulus.he somatosensory association cortex is located in the superior parietal lobe (a.k.a. posterior parietal cortex), which is posterior to SI. The highest degree of convergence of somatosensory information occurs in the posterior parietal cortex.
