A
Somatic Nervous System
B
Autonomic Nervous System
C
Enteric Nervous System
D
Central Nervous System
Verified step by step guidance1
Understand the basic divisions of the human nervous system: the Central Nervous System (CNS) and the Peripheral Nervous System (PNS). The CNS includes the brain and spinal cord, while the PNS includes all the nerves outside the CNS.
Recognize that the Peripheral Nervous System is further divided into the Somatic Nervous System and the Autonomic Nervous System. The Somatic Nervous System is responsible for voluntary movements, while the Autonomic Nervous System controls involuntary functions.
Identify the role of the Somatic Nervous System: it carries signals from the CNS to skeletal muscles, enabling voluntary movements such as walking, typing, or lifting objects.
Differentiate the Autonomic Nervous System, which is responsible for regulating involuntary body functions like heart rate, digestion, and respiratory rate. It is further divided into the sympathetic and parasympathetic nervous systems.
Conclude that the division of the human nervous system that carries signals to skeletal muscles is the Somatic Nervous System, as it is responsible for voluntary control of body movements.
