Axon consists of elongated fibers that extend from the cell body to the terminal endings and aids in transmitting signals. Some axons have a fatty substance called myelin, which acts as an insulator and can transmit signals much faster than other neurons. Axon elongated fibers connect with other cells in the body through the synapses (Stern, Fava, Wilens, & Rosenbaum, 2016) 2.The major components that make up the subcortical structures include the cerebellum, basal ganglia, and the thalamus, hypothalamus, pituitary, and brainstem. The frontal lobe is involved in functions such as planning, attention, problem-solving, judgment, and initiative. The following components play a role in learning, memory, and addiction. The cerebellum is responsible for motor coordination and learning. The ventral striatum plays a vital role in emotion and learning via connections with the hippocampus, amygdala, and prefrontal cortex. The two critical neurotransmitters located in the nigra striatal region of the brain that plays a significant role in motor control is Dopamine and GABAergic neurons (Sonne, 2020) 3.Glia cells are non-neuronal cells in the central nervous system and do not produce electrical impulses. Glia cells maintain homeostasis, form myelin, and provide support and protection for neurons. Glia cells are divided into two groups, microglia cells and macroglia cells; Macroglia cells can be further divided into astrocytes and oligodendrocytes. Microglia cells act as a primary immune defense of the central nervous system, travel and remove damaged substances, pathogens, or other foreign substances. Glia cells also play a role in neurotransmission and synaptic connections and the physiological processes of breathing. Astrocytes are star-shaped glia cells with many fun
