The nervous system transmits signals between the brain and the rest of the body, including internal organs. In this way, the nervous system's activity controls the ability to move, breathe, see, think, and more. 1 The basic unit of the nervous system is a nerve cell, or neuron. The human brain contains about 100 billion neurons.

The nervous system is a network of special cells, neurons and ganglia, that work together to carry out the transmission and reception of signals between different parts of our body. The signals are transmitted in the form of electrochemical waves or chemicals.

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 12.2 ).

The nervous system or the neural system is a complex network of neurons specialized to carry messages. The complexity of the nervous system increases as we move towards higher animals. For instance, cnidarians such as jellyfish have relatively simple nerve nets spread throughout their body.

The nervous system produces a response in effector organs (such as muscles or glands) due to the sensory stimuli. The motor ( efferent) branch of the PNS carries signals away from the CNS to the effector organs. When the effector organ is a skeletal muscle, the neuron carrying the information is called a somatic motor neuron; when the effector.

In biology, the nervous system is the highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from different parts of its body. The nervous system detects environmental changes that impact the body, then works in tandem with the endocrine system to respond to such events. [1]

Table 11.2.1 11.2. 1: Name of structures depend on the location. A group of neuron cell bodies within the gray matter is called a nucleus in the CNS and a ganglion in the PNS. A bundle of axon within the white matter is called a tract or column in the CNS, and a nerve or nerve fiber in the PNS. CNS.

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.
