Somatic components

Although the nervous system is often discussed in terms of peripheral and central components, it should be regarded as a highly integrated whole in which the central nervous system (brain and spinal cord) plays a critical information gathering and processing role. The peripheral nervous system is often divided into the autonomic and somatic components. The somatic system controls the voluntary functions of the body, like those of the skeletal muscles. The... 

The penis is innervated by autonomic and somatic nerves. The somatic component is controlled by the pudendal nerve, which is responsible for penile sensation and the contraction and relaxation of the bulbocavernosus and ischiocavernosus striated muscles. Blood flow during erection and detumescence is regulated via the cavernous nerves, consisting of sympathetic and parasympathetic nerve fibers, which merge to form these nerves in the pelvis. 

The somatic component of the disease process may be catrsed by a direct bodily injtrry (such as a blow to the skeletal stmctrrres), or it may represerrt the resporrse of viscera to pathology. 

The somatic component is often discussed as a totally independent, voluntary system respon-... 

Finally, entry of Ca + through somatic and dendritic Ca + channels activates calmodulin-dependent protein kinases to modulate transcription, and thereby plays a crucial role in certain components of neural development and plasticity. 

The afferent division carries sensory information toward the CNS and the efferent division carries motor information away from the CNS toward the effector tissues (muscles and glands). The efferent division is further divided into two components (1) the somatic nervous system, which consists of motor neurons that innervate skeletal muscle and (2) the autonomic nervous system that innervates cardiac muscle, smooth muscle, and glands. 

Another characteristic to take into account is that ATP is an endogenous component of the cells, both somatic and bacterial. Therefore, an extraction step must to be included in the assay protocol it is very simple and quick to perform. Several extraction methods have been reported, both physical and chemical, such as heating and the use of surfactants, trichloroacetic acid, and organic solvents [89, 120, 121], The chemical methods are generally preferred the addition of a surfactant can be effective in most cases. The use of mild or strong extraction... 

Somatic motor and sensory neurons that give rise to PNS axons maintain large fractions of their total protoplasmic bulk within the CNS. Many of the extracellular matrix components and axonal guidance molecules involved in... 

Beach and Amir have demonstrated that with a given sample using the same procedures, some markers of depression may define a taxon, while others do not. In other words, both continuous and taxonic forms of depression exist. However, questions remain about the nature of the identified taxon. Is it really a depression taxon or has the exclusive focus on vegetative symptoms changed the nature of the construct Interestingly, certain somatic symptoms, such as sleep and appetite disturbance, are common in many disorders and can be considered the physical component of nonspecific distress (Clark Watson, 1991). Thus, perhaps the identified taxon is not a depression taxon at all and actually reflects general somatic complaints. Only construct validation can address these concerns. 

Vomiting is a protective reflex of high complexity and integration involving autonomic and somatic nervous system components which results in an ejection of the gastrointestinal (GI) contents. This reflex is widely distributed among animals, including some insectivores [39], but absent in laboratory rodents [40].

Lateral efferents of the MPOA innervate septum, amygdala, other hypothalamic regions, ventral tegmental area (VTA) of the midbrain, and midbrain central gray matter (Numan, 1986). Studies have shown that the MPOA-VTA-basal ganglia (BG) circuit is believed to be of importance in maternal behavior because the BG is a major component of the extrapyramidal system (EPS) (Numan, 1986). Perhaps MPOA neurons relevant to maternal behavior via the BG to EPS promote the somatic-motor processes underlying maternal responsiveness (Numan, 1986).
