Here are some key similarities and differences when comparing the CNS (Brain & spinal cord) and PNS (somatic/autonomic & sympathetic/parasympathetic). Show CENTRAL NERVOUS SYSTEM (brain & spinal cord) Similarities: The brain stem and spinal cord both control involuntary processes (e.g. the brain stem controls breathing and the spinal cord controls involuntary reflexes). Differences: The brain provides conscious awareness and allows for higher-order thinking, while the spinal cord allows for simple reflex responses. The brain consists of multiple regions responsible for different functions, whereas the spinal cord has one main function. PERIPHERAL NERVOUS SYSTEM (somatic/autonomic & sympathetic/parasympathetic) Similarities: The sympathetic nervous system (part of the autonomic nervous system) and the somatic nervous system respond to external stimuli. The sympathetic nervous system responds to external stimuli by preparing the body for fight or flight and the somatic nervous system responds to external stimuli (by carrying information from sensory receptors to the spinal cord and brain). Differences: The autonomic nervous system consists of two sub-components, whereas the somatic nervous system only has one. The somatic nervous system has sensory and motor pathways, whereas the autonomic nervous system only has motor pathways. The autonomic nervous system controls internal organs and glands, while the somatic nervous system controls muscles and movement. The brain consists of multiple regions responsible for different functions, whereas the spinal cord has one main function. What are the similarities and differences between CNS and PNS?Central nervous system (CNS) consists of brain and spinal cord of the body. Peripheral nervous system (PNS) consists of dorsal and ventral root nerve cell heads, spinal and cranial nerves. Central nervous system (CNS) Controls all the voluntary functions of the body.
What are the differences between the central nervous system and the peripheral nervous system?The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.
Which of the following is a similarity between the CNS and the PNS?Which of the following is a similarity between the central nervous system and the peripheral nervous system? Their structures are composed of neurons and neuroglia.
