The nervous system is a complex network of cells, tissues, and organs that coordinates the body's responses to internal and external stimuli. It consists of two main parts: the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which consists of all the nerves that lie outside the CNS. The nervous system plays a vital role in maintaining homeostasis, the state of balance within the body, and is responsible for three primary functions: sensory input, integration, and motor output.
Sensory input: The nervous system receives and processes sensory information from the external environment and internal organs. This includes information about temperature, pressure, pain, taste, smell, and sight, as well as information about the body's own movement and position. Specialized sensory receptors in the skin, eyes, ears, nose, and other organs detect these stimuli and send signals to the CNS through sensory neurons.
Integration: The CNS receives and interprets the sensory input it receives and coordinates the body's response. The brain and spinal cord process the information and decide how to react to it. For example, if a person touches a hot stove, the sensory receptors in the skin will detect the heat and send a signal to the CNS. The CNS will then interpret this as a harmful stimulus and send a signal to the muscles to move the hand away from the stove.
Motor output: The nervous system also sends signals to the muscles and organs to produce a response to the stimuli it receives. Motor neurons carry these signals from the CNS to the muscles, causing them to contract and produce movement. The nervous system also sends signals to glands, which release hormones and other chemical messengers into the bloodstream to regulate various bodily functions.
In summary, the three primary functions of the nervous system are sensory input, integration, and motor output. It receives and processes sensory information, interprets it, and coordinates the body's response through the actions of muscles and glands. The nervous system is essential for maintaining homeostasis and enabling the body to adapt to its environment.
What are the functions of nervous system?
The brain is protected by the skull the cranial cavity and the spinal cord travels from the back of the brain, down the center of the spine, stopping in the lumbar region of the lower back. Remaining neurons, and associated cells, distributed throughout the body form the PNS. First, the nervous system collects sensory input from the body and external environment. CNS sends out nerve impulses to effector organs muscles and glands in response to sensory input. When these signals reach the end of a neuron, they stimulate the release of chemicals called neurotransmitters. These are found housed within the skull and vertebral column respectively. First, the basic functions of the nervous system are sensation, integration, and response.
