What is the Somatic Nervous System?
The somatic nervous system (SNS) is a crucial part of the peripheral nervous system. It works in conjunction with the central nervous system to control voluntary muscular movements. The SNS consists of sensory nerves and motor nerves. Sensory nerves provide feedback to the brain about bodies external environment, while motor nerves control body movements by transmitting signals from the brain and spinal cord to the skeletal muscles.
Role and Functionality
The principal function of the somatic nervous system is to transmit sensory and motor signals, back and forth, from the central nervous system. The SNS plays a vital role in our daily activities like reading, walking, talking and generally interacting with our surrounding environment. It is often considered our 'conscious' nervous system because it lets us control our bodily actions.
Comparison with Other Nervous Systems
The human nervous system is divided into two main parts; the central nervous system (CNS) and the peripheral nervous system (PNS). The Somatic Nervous System, as part of the PNS, differs from other parts of the nervous system in some key ways.
- Peripheral Nervous System (PNS): The PNS is responsible for carrying messages from the CNS to the rest of the body. Its two main divisions are the Somatic Nervous System and the Autonomic Nervous System.
- Autonomic Nervous System (ANS): Unlike the SNS, which covers voluntary actions, the ANS governs involuntary functions like heartbeat, digestion, and breathing.
Clinical Relevance and Common Disorders
The somatic nervous system disorders often result in motor and sensory deficits. Some of the common disorders include radiculopathy, carpal tunnel syndrome, and brachial plexus injuries. Understanding the nature and functionality of the SNS is critical to managing these conditions. It is also central to the field of neurophysiotherapy.
Training in Nervous System Fields
For those interested in specializing in the nervous system fields, neuroscience training is a crucial starting point. This branch of biology not only explores the structure, function, and development of the nervous system but also investigates how the nervous system can be manipulated, treated, or repaired.
FAQs
Q1: What is the main function of the somatic nervous system?
The primary role of the SNS is to control voluntary actions. It does this by transmitting sensory and motor information between your central nervous system and your muscles.
Q2: How does the somatic nervous system differ from the autonomic nervous system?
The somatic nervous system controls voluntary actions, and the autonomic nervous system controls involuntary functions, such as heart rate, digestion, and breathing.
Q3: How is the somatic nervous system related to mental health?
Although the SNS primarily controls physical responses, it's indirectly tied to mental health. Increased understanding of these connections can help in developing therapies for mental health conditions like anxiety disorders and depression.
Q4: What are some common disorders of the somatic nervous system?
Some common disorders include radiculopathy, carpal tunnel syndrome, and brachial plexus injuries.
Q5: What kind of training is available for those interested in studying the nervous system?
Students can pursue a variety of disciplines, including neuroscience, neurophysiology, and neuropsychology. These fields offer in-depth studies about the structure, function, and disorders of the nervous system.
Understanding the human somatic nervous system is a key component of advancing our knowledge of body functions, and improving the way we treat many disorders. With ongoing research and focused training, we can continue to make significant strides in this exciting and crucial field of health care.
