A sophisticated network of specialized cells and structures called the human nervous system carries messages from one area of the body to another. It is essential for regulating and coordinating a variety of body processes, such as movement, sensation, cognition, and others. The central nervous system (CNS) and the peripheral nervous system (PNS) are the two primary divisions of the nervous system

.Central Nervous System (CNS):

The brain and spinal cord make up the CNS. It acts as the body's command and control center, processing data, making judgment calls, and issuing orders. The spinal cord serves as a communication link between the brain and the rest of the body, whereas the brain is in charge of many cognitive processes, emotions, and voluntary movements. Brain: The brain is organized into many areas, each of which performs a certain function. Higher-order thinking, sensory perception, motor control, and language are all functions of the cerebral cortex, the outermost layer of the brain. Basic bodily processes including breathing, heart rhythm, and digestion are controlled by the brainstem. The cerebellum orchestrates posture, balance, and movement. a bundle of nerves that runs from the base of the spine to the base of theThe CNS is made up of the spinal cord and brain. It serves as the organization's command and control center, processing information, making decisions, and giving directives. The brain controls a variety of cognitive functions, emotions, and voluntary actions, while the spinal cord acts as a communication channel between the brain and the rest of the body. Brain: The brain is divided into several regions, each of which has a certain job to do. The cerebral cortex, the brain's outermost layer, is responsible for higher-order reasoning, sensory perception, motor control, and language. The brainstem regulates fundamental biological functions including breathing, heartbeat, and digestion. The cerebellum coordinates movement, balance, and posture. a string of nerves that extends from the

Peripheral Nervous System (PNS):

The PNS connects the CNS to different organs, muscles, and tissues by way of nerves and ganglia (clusters of nerve cell bodies) that run throughout the body. The somatic nervous system and the autonomic nervous system are additional divisions. The somatic nervous system regulates voluntary movements and sends sensory data from the body's sensory receptors to the central nervous system (CNS). It helps us to actively engage with our surroundings. The Autonomic Nervous System (ANS) controls automatic body processes including breathing, digestion, and heart rate. It is further split into the sympathetic and parasympathetic divisions, which have opposing effects on distinct physiological processes and enable the body to react suitably to varied circumstances. Through specialized cells called neurons, the nervous system transmits information.Through the body's network of nerves and ganglia (clusters of nerve cell bodies), the PNS links the CNS to various organs, muscles, and tissues. Additional divisions include the autonomic nervous system and the somatic nervous system. The somatic nervous system controls voluntary movements and communicates sensory information to the central nervous system (CNS) through the body's sensory receptors. It enables us to actively interact with our environment. Breathing, digestion, and heart rate are among the automatic bodily functions that are under the direction of the autonomic nervous system (ANS). The sympathetic and parasympathetic divisions of it are further divided, and they both have opposing impacts on different physiological functions, allowing the body to respond to various situations in a way that is appropriate for the situation. Information is transmitted by the nervous system through specialized cells called neurons.
