Dr Ayisha Qureshi Assistant Professor MBBS MPhil DIVISIONS OF THE PERIPHERAL NERVOUS SYSTEM Differentiating between the somatic amp autonomic nervous system SOMATIC NERVOUS SYSTEM AUTONOMIC. It influences the function of internal . organs. It acts largely unconsciously. The autonomic nervous system. It . regulates bodily functions such as heart rate, digestion, urination, respiratory rate . The efferent nervous system has two components:. the somatic and . the autonomic. . These two systems differ in a number of ways but are chiefly distinguished by the types of effector organs they innervate and the types of functions they control. . Introduction.
