Abstract

Nervous system is the major communication system in animals. Neurons are the structural and functional unit of the nervous system. There are numerous specialized contact areas known as synapses, which mediate signals from one neuron to others. Neurotransmitters are the chemical messengers liberated at the nerve endings and help to transfer the nerve impulses in the presynaptic neuron to adjacent postsynaptic neurons or muscle or glands. The nervous system has two main subdivisions, the central nervous system (CNS) and peripheral nervous system (PNS), which act together in a synchronous pattern with each other. The central nervous system is the major processing center in the body, which is composed of the brain and spinal cord. The sensory receptors are present throughout the body, which continuously monitor the external as well as the internal environment and send the information to the CNS via PNS. The information is then analyzed in the CNS, which sends signals to the target organ through PNS. Then the particular organ takes necessary action according to the need. The two main subdivisions of PNS are somatic nervous system and autonomic nervous system. The somatic nervous system is associated with the voluntary movement of skeletal muscles, whereas the autonomic nervous system regulates the involuntary functions of organs and tissues.

Graphical Abstract

A diagram of the sensory receptors, via the sensory neurons to the interneurons to the muscle and gland effectors.

Description of the graphic: Receptors are sensory structures to detect changes in the internal or external environment (1). The sensory division of the PNS brings information to the CNS from receptors in peripheral tissue and organs (2). Information processing includes the integration and distribution of information in the CNS (3). The motor division of the PNS carries motor commands from the CNS to peripheral tissue and systems (4). Effectors are target organs whose activities change in response to neural commands (5)
