Nov 17, 2022 · The central nervous system (CNS) consists of the brain and spinal cord. The CNS is the body and mind's control center. Like a central communication hub, it receives, processes, and responds to all types of sensory input. The CNS also controls voluntary muscle movements and motor functions. "Nervous system " is an umbrella term for the bodily ...
Oct 10, 2022 · The nervous system is a complex network that enables an organism to interact with its surroundings. Sensory components that detect environmental stimuli and motor components that provide skeletal, cardiac, and smooth muscle control and control of glandular secretions are coordinated in a system to compel appropriate motor responses to the stimuli or sensory inputs that have been received ...

Sep 19, 2022 · The central nervous system (CNS) is a biological computer responsible for conscious and unconscious processes. It controls automatic systems, voluntary movements, thoughts, emotions, logic, and sensory interpretation. This article describes the CNS function and structure. It also covers some of the conditions that can affect it.
The central nervous system consists of the brain and spinal cord, both derived from the embryonic neural tube. Both are surrounded by protective membranes called the meninges, and both float in a crystal-clear cerebrospinal fluid. The brain is encased in a bony vault, the neurocranium, while the cylindrical and elongated spinal cord lies in the ...

Nov 12, 2023 · Function. The CNS controls our body’s voluntary (e.g. walking) and involuntary (e.g. breathing) functions. The brain is responsible for generating our thoughts as well as interpreting information from the PNS and responding appropriately. This process is made possible by tracts of nerve cells in the spinal cord which connect the brain to the PNS.
May 13, 2022 · The nervous system can be divided into two major regions: the central and peripheral nervous systems. The central nervous system (CNS) is the brain and spinal cord, and the peripheral nervous system (PNS) is everything else (Figure \(\PageIndex{1}\)). The brain is contained within the cranial cavity of the skull, and the spinal cord is ...
