Somatic Nervous System
What is the Somatic Nervous System?
The somatic nervous system is responsible for voluntary control of skeletal muscles and the transmission of sensory information to the central nervous system.
What are the 31 Pairs of the Somatic Nervous System?
The somatic nervous system comprises 31 pairs of spinal nerves, including 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal nerves, each contributing to voluntary muscle control and sensory perception in specific regions of the body.
What is the Difference Between the Autonomic and Somatic Nervous Systems?
The autonomic nervous system controls involuntary bodily functions, while the somatic nervous system controls voluntary movements.
What is the Function of the Somatic Sensory System?
The somatic sensory system processes sensory information from the body’s external environment.
What is the Somatic Response System?
The somatic response system coordinates voluntary movements and reflex actions.
What is the Difference Between the Central Nervous System and the Autonomic Nervous System?
The central nervous system includes the brain and spinal cord, while the autonomic nervous system regulates involuntary functions like heart rate and digestion.
Somatic Nervous System
The somatic nervous system (SNS) controls voluntary movements and reflex arcs by transmitting sensory information to the central nervous system (CNS) and motor commands from the CNS to skeletal muscles. It consists of motor neurons that stimulate muscle contractions and sensory neurons that relay information from sensory organs. The SNS enables conscious control over bodily movements and responds to external stimuli. It plays an important role in activities such as walking, grasping, and reflex actions.
In this article, we will study the somatic nervous system, its components, functions, mechanism of action and disorders in detail.
