Functions of the Somatic Nervous System

The somatic nervous system is responsible for controlling voluntary movements and transmitting sensory information from the body to the central nervous system. It consists of nerves that originate from the brain and spinal cord and innervate the skeletal muscles, skin, and sense organs. Here are the functions of the somatic nervous system:

1. Control by the Central Nervous System: The somatic nervous system is controlled by the central nervous system, which includes the brain and spinal cord. The central nervous system sends signals to the somatic nerves to initiate voluntary movements and receive sensory information from the body.

2. Nerves Originating from the Brain and Spinal Cord: The nerves of the somatic nervous system originate from both the brain and spinal cord. The cranial nerves arise from the brain and innervate the muscles and sense organs of the head and neck. The spinal nerves arise from the spinal cord and innervate the muscles and skin of the rest of the body.

3. Division into Sympathetic and Parasympathetic Nervous Systems: The somatic nervous system is distinct from the autonomic nervous system, which controls involuntary functions. The autonomic nervous system is further divided into the sympathetic and parasympathetic nervous systems. The sympathetic nervous system prepares the body for "fight or flight" responses, while the parasympathetic nervous system promotes "rest and digest" responses.

4. Innervation of Sensory Organs, Internal Organs, Muscles, Skin, and Sense Organs: The somatic nervous system innervates various structures in the body. It provides sensory innervation to the skin, allowing us to perceive touch, temperature, and pain. It also innervates the skeletal muscles, enabling voluntary movements. Additionally, the somatic nervous system innervates the sense organs, such as the eyes, ears, nose, and tongue, allowing us to perceive the external environment. It does not directly innervate internal organs.

5. Regulation without Conscious Awareness: The regulation of the somatic nervous system occurs without conscious awareness. This means that we do not have to consciously think about or control the movements of our skeletal muscles or the sensory information we receive from the body. The somatic nervous system functions automatically, allowing us to perform daily activities effortlessly.
