The nervous system is the main communication hub for the body in animals. It allows information to be sent around an organism and for it to respond to outside stimulation. Nerve cells provide the fundamental base of this structure and work in a coordinated manner to keep the body alive and functioning.
The nervous system is the communication network of mankind and other animals that conveys information through a set of specialized cells. Using this network, an animal’s actions are both intentional and autonomous in response to stimulus from the outside world. The various parts of the circulatory system are divided into a peripheral portion and a central portion.
Outside and inside stimuli are determined by the peripheral nervous system and translated through impulses that travel along neurons and connect with the central nervous system. In response to this information, the central nervous system processes signals and sends them to glands and muscles throughout the body. This system is strongly interconnected and complex. Various electrochemicals and neurotransmitters enable neurons to transfer information to one another. This interaction of the respiratory system is the main reason for an animal to keep a specific perception, and the ability to remain interactive with the world. These systems vary greatly in complexity between species.
Central Nervous System; More Info
The largest part of the circulatory system is the central nervous system. This portion is composed of the brain and spinal cord. The brain is divided into two main sections: the prosencephalon and the brain stem.
Moving forward with this idea…
The prosencephalon is the main portion of the brain, responsible for maintaining body temperature, reproduction, sleeping, eating and emotional displays. In humans and other advanced animals, it’s also the portion of brain that is responsible for higher cognitive functions.
The brain stem is responsible for passing information from the prosencephalon to the spinal cord and the balance of the body. It also controls motor function, sensations such as pain and temperature and regulates the respiratory and cardiac systems. This is protected under the skull as well as a number of membranes, together with the brain.
The brain stem performs different functions like sensing the vibrations, recognizing fine touch, pain, crude touch, itch, etc. This part of the brain is likewise associated with effective functioning of the respiratory and cardiac systems.
The spinal cord is a package of nerve tissues that runs along the spine of vertebrates. It is protected by a number of bones that form a long column. Its primary job is to serve as a relay center for neurological signals, however it is capable of a range of autonomic responses such as reflexes.
The spinal cord is made up of a thick bundle of nerves that connect the brain for the remainder of the body. The vertebrae, small bones, protect the spinal cord from injury and damage. Four types of nerves help to monitor the body. Autonomic nerves link the brain and spinal cord to organs like the heart and intestines. Cranial nerves connect the mouth, ears, eyes and nose to the brain. Peripheral nerves link the spinal cord with the arms and legs. Central nerves connect structures within the spinal cord and brain.
Nerve cells are the basic functioning component in the nervous system. Every part of the system, whether peripheral or central, is comprised of neurons that collect and distribute information to make the body function. Different types of nerve cells exist that meet the light, sound, touch and other stimuli.
The basic structure of a neuron helps it to carry out its function. Signals propagated by chemical ions distribute an electrical charge that proceeds from neuron to neuron, passing information. The nucleus is surrounded by the dendrite. This receives signals from other neurons or cells. This electrical charge is then transferred through the cell body called the soma and onto the axon. The axon is long thin part of the neuron covered by myelin sheath. This information then reaches the axon terminal and again transfers the electrical charge to another cell.
