The Peripheral Nervous System

The spinal cord is the final common pathway from the brain to the muscles. It controls all the sensory inputs received from different locations throughout the body. The spinal cord also controls voluntary muscle responses. Some elementary reflexes are local to the spinal cord, but voluntary muscle

The central nervous system is composed of the brain and spinal cord and the peripheral nervous system is composed of the body’s sensory receptors, muscles, and glands. The peripheral nervous system is made up of somatic and automatic. Somatic is the voluntary movement of our skeletal muscles. When we hear the bell ring, our somatic nervous system carries the message to the brain and the brain reports back to our muscles. The autonomic nervous system controls our glands and muscles in our internal organs. Some things this nervous system does is taking control of our digestive system and our heart beat. There are two functions of the autonomic nervous system- the sympathetic and the parasympathetic nervous system. The sympathetic nervous system arouses and expands energy. If someone gets excited or nervous in a situation, their blood pressure will rise, their digestion will slow down, their heartbeat will accelerate, their blood sugar will rise, and they will sweat to cool down. The parasympathetic is the opposite. It tries to conserve energy by decreasing your heartbeat, lowering your blood sugar, and so

activities of the skin, muscles and many peripheral tissues. This includes the 12 cranial nerves

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.

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 CNS contains the brain and spinal cord. Its main functions include: processing, integrating, and coordinating sensory information and motor instructions. The sensory data conducts information that is being processed from internal and external conditions the body is experiencing. Motor commands regulate and control peripheral organs (skeletal muscles). The brain functions under memory, emotions, learning, and intelligence. The PNS consist of the neural tissue found outside of the CNS. It functions in sending data to the CNS which motor commands are than carried out to the peripheral tissues/systems. Multiple nerve fibers send sensory data and motor commands in the PNS. The nerves that assist with transmitting data include the cranial nerves and spinal nerve. However, the PNS can be divided into afferent (to bring in) and efferent (to bring out) divisions of transferring data. The afferent division functions in bringing in sensory data to the CNS. Sensory structures are receptors that detect internal/external environmental change and adjusting accordingly. The efferent division functions in carrying out motor commands from the CNS to glands, muscles, and adipose tissue. The efferent division contains somatic

The central nervous system (CNS) is part of the human body which includes the brain and spinal cord (Lewis, Heitkemper, Dirksen, & Bucher, 2014). The cells of the nervous system are known as neurons, which is protected and nourished by neuroglia (Lewis et al., 2014). The spinal cord includes ascending and descending tracts which controls sensory and muscle movements (Lewis et al., 2015)

The nervous system helps maintain homeostasis by controlling and regulating the other parts of the body. A deviation from a normal set point act as a stimulus to a receptor, which sends nerve impulses to a regulating center in the brain. For example, “breathing is involuntary, the nervous system ensures that the body is getting much needed oxygen through breathing the appropriate amount of oxygen.” This shows that the nervous system plays a role in making sure that the breathing patterns of a human stays constant in order to maintain homeostasis. This system is the control center of the human body. The Control center sets the range of value to be maintained and is made up of the brain, spinal cord and nerves. The nervous system is important to the human body because its an organ system in charge of sending messages to and from the brain and spinal cord to and from all parts of the body. What helps send these messages are nerves, one or more bundles of fibers forming part of a system that conveys impulses of sensation, motion, etc, between the brain or spinal cord and other parts of the body. Nerves act as highways to carry signals between the brain and spinal cord and the rest of the body. The Central Nervous system is the complex of nerve tissues that controls the activities of the body, it consists of two parts: the brain and the spinal cord. The brain is arguably the most important organ in the human body. It controls and coordinates actions and reactions, allows us to think and feel enables us to have memories and feelings- all the things that makes us human. Three main parts of the brain is the forebrain, midbrain, hindbrain. The Forebrain consists of the cerebrum, thalamus, and hypothalamus, The Midbrain consists of the tectum and tegmentum, The Hindbrain is made of the cerebrum, pons and medulla, brainstem.

Whereas the spinal cord (often referred to as the brainstem) is the pathways that enables nerve impulses to reach their various destinations in the body. The central nervous system main function is to receive information from the different parts of the body, in which must be analysed and stored in order for it to send out instructions based on those pieces of information. The central nervous system’s main function is to coordinate the numerous organs and muscles required to perform the individual’s desired action(s) (Walker, 2005).

The nervous system is a complex network which is composed of nerves and cells that transport information to and from the brain and spinal cord toward different body parts. The nervous system is composed of the central nervous system and the peripheral nervous system. The central nervous system is constituted of the spinal cord and the brain. The central nervous system comports the glycerin, which acts as a neurotransmitter and plays an important role in the processing of motor and sensory information that control movements, vision, and audition (Hossain, Al-Dirini, & Sakafidas, 2014). Findings from O’Connor (2016) reveals that the Central nervous system serves as the human body major control system; it is responsible for synchronizing body

Central nervous system- Consists of the Brain, Spinal Cord, and Autonomic nervous system (ANS). The brain is the center of the nervous system.

The central nervous system and the peripheral nervous system work together to collect information from within the body and from the environment outside it. The systems process all the collected information and send instructions to the body; to obtain an appropriate response. Once the data arrives, the brain will sort and file it before sending out any commands on what to do. The central system is the main command center of the body that contains the brain as well as the spinal cord. The peripheral nervous system contains a network of nerves that connect the rest of the body to the central nervous system.

It is made up of many branches that coordinate different nervous activities in our bodies. The two main parts are the central nervous system (CNS), which is composed of the brain and spinal chord (Fig. 1), and the peripheral nervous system (PNS), which has several more extensions. The PNS consists of the nerves that radiate from the CNS; this includes the 12

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.
