The spinal cord is a single structure, whereas the adult brain is described in terms of four major regions: the cerebrum, the diencephalon, the brain stem, and the cerebellum. A person’s conscious experiences are based on neural activity in the brain. The regulation of homeostasis is governed by a specialized region in the brain.

Stimuli from varying sources, and of different types, are received and changed into the electrochemical signals of the nervous system. This occurs when a stimulus changes the cell membrane potential of a sensory neuron. The stimulus causes the sensory cell to produce an action potential that is relayed into the central nervous system (CNS).

The cerebrum is divided into different regions called lobes: frontal, parietal, occipital, temporal and insula. Each lobe performs a specialized function through their cerebral cortex. Overall, the functions of the cerebrum are motor initiation and coordination, processing of general and special senses, and high level functions such as judgment, reasoning, problem solving, and learning.

The signal is transmitted to the brain where it is interpreted, and then signals are quickly sent to the hand to pull away from the hot stimuli. All sensory signals, except olfactory system input, are transmitted to the thalamus and to the appropriate region of the cortex of the brain.

The general sense of somatosensation (touch) contains receptors spread throughout the body. Taste and smell belong to the special senses and rely on chemoreceptor cells. Taste transduction depends on gustatory receptor cells of the taste buds within papillae. Smell transduction depends on olfactory receptor neurons within the olfactory epithelium.

The nervous tissue can be visibly differentiated between white and gray matter. This difference is due to a substance called myelin, that insulates neurons. The nervous system (NS) can be divided anatomically in central nervous system (CNS) which includes brain and spinal cord, and peripheral nervous system (PNS) which includes nerves and ganglia. Functionally the NS can be divided in somatic, autonomic and enteric divisions.
