Literature Review On The Nervous System

1.An extensive network of specialized cells that carry information to and from all parts of the body is called the nervous system.

The nervous system is one of the body’s complex functions that contain a network of cells and nerves that transmit signals from the brain and spinal cord to different areas of the body. It is categorized into two groups; the central nervous system which is made up of the brain and spinal cord, and the peripheral nervous system which contains the body’s nervous tissue and is where neurologic responses occur. Homeostasis, which is the process in which thermoregulation is maintained, also happens in this area.

The nervous system consists of the brain, spinal cord, and a complex network of neurons. This system is responsible for sending, receiving, and interpreting information from all parts of the body. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment. This system can be divided into two parts: the central nervous system and the peripheral nervous system. Let 's take a look at the central nervous system.

The nervous system is split up into two main organizations, the central nervous system (CNS) and the peripheral nervous system.

The nervous system is made up of basic units called neurons. The main role of the neurons is to receive, integrate and transmit information throughout the body. There are some neuroglial cells found in nervous system aswell which provide support to the neurons by giving protection and nourishment Neurons have nerve processes that looks like finger like projections extended from the nerve cell body. They also contain axons and dendrites which enable them to transmit signals throughout the body. Normally, axon carry signals away from the cell body and dendrites carry signals toward the cell body according to Regina Bailey (2013). Neurons have three different shapes: bipolar, unipolar and multipolar where bipolar has two neuronal processes coming out of the cell body, unipolar has only one neuronal process coming out of the cell body and multipolar has many neuronal processes coming out of the cell body.

In the organization of the Human Nervous System it is divided into sections such as the sensory system, which gathers and process information from the surrounding environment: motor systems which responds from environment by sending signals and information to facilitate movement behavioral responses and the associational system which is a meditator from most multifaceted and least problematic brain functions. Within these different functions of the nervous system it is divided into two components where these functions can happen the central nervous system that comprises of brain and spinal cord and peripheral nervous system that embodies nerves and ganglia.

The Central nervous systems include the brain and spinal cord which transfers voluntary nerve impulse to skeletal muscles, skin, muscles, and glands.

Our nervous system is there to help to transfer the things our body feels and what we need. The nervous is broken up into two parts, the central nervous system (CNS), and the peripheral nervous system (PNS). The CNS controls the brain and the spinal cord, the PNS controls the nerves and the ganglia (a small mass of gray matter). Our body uses the spinal cord to send messages to the nerves so that it can control our organs and muscles.

The nervous system is made up of trillions of nerve cells, or neurones, even though we don’t use

There are two main divisions that comprise the nervous system: the central nervous system consisting of the brain and the spinal cord and the peripheral nervous system consisting of somatic and autonomic nervous systems (Kalat, 2013). The brain and the spinal cord make up the central nervous system and is responsible for the transmission of nervous impulses as well as receiving sensory information (Siegal, 1999). The peripheral nervous system, consisting of cranial nerves, spinal nerves, and peripheral ganglia, is responsible for transmitting information to the central nervous system as well as the rest of the body (Hubbard, 2013).

The nervous system has two overarching areas: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is known as the control center as it includes the brain and the spinal. Whereas the PNS includes the nerves leading all around the rest of the body, running to places like your fingers and toes.

The anatomical and functional divisions of the nervous system are divided into two categories the central nervous system (CNS) and the peripheral nervous system (PNS).

The peripheral nervous system (PNS) is connected directly to the central nervous system, and consists of neurons and nerves that send information back and forth the CNS. Furthermore, the peripheral nervous system can be divided into two sections, the sensory nervous system and the motor nervous system. The Sensory The sensory nervous system is in charge of transmitting data from a variety of internal organs or from external stimuli to the central nervous system using sensory nervous cells. On the other hand, the cells of the motor nervous system (motor neurons), take the impulse from the CNS to effectors, which include glands and muscles. In addition, the motor nervous system can be further divided into the somatic nervous system, controls voluntary actions of the skeletal muscle and external sensory organs, whilst the autonomic nervous system operates

The nervous system is divided into two major sections: There is the central nervous system and the peripheral nervous system.

The human nervous system is divided into two parts, the central nervous system and the peripheral nervous system. The central nervous system, CNS, is just the brain and spinal cord. The peripheral nervous system, PNS, includes the nerves and neurons that extend outwards from CNS, to transmit information to your limbs and organs for example. Communication between your cells is extremely important, neurons are the messengers that relay information to and from your brain.
