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

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.

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 central nervous system is made of the brain and spinal cord, where the brain is the control center for integration and motor output.

This controls our thoughts, our emotions, movements that our boy makes. Our system also controls what our body does by our heart rate, body temperature, our breathing, and our hormones that we carry in our system. When it comes to our eyes the optic nerve, olfactory nerves that we have, and olfactory epithelium they consider to have a part in our nervous ssystem. Theseare directly connected to our brain tissue that intermediate never connects. This comes to the brain complex in our bodies the cerebral can contains an estimated 15-33 billion for each that is connected to a thousand neurons. When it comes to the brain our body can use twenty percent of the energy that we carry. Our brain is the central coordination for the activity for our body structures. When it comes to the spinal portion this will run the full llengthof our body that has a very big amount for our body and brain to interact that carries out task. When the spinal cord meet up with our brain that carries thirty one of the nerves that is running through our spinal cords. This connects the peripheral system that will run through our whole body to our muscles and all our

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 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.

There are two ways to classify the nervous system: structural and functional classifications. Structural classification includes all the organs of the nervous system. There are two groups that forms nervous system: central nervous system (CNS) and peripheral nervous system (PNS). CNS covers the brain and spinal cord of the human body. It unites and gives orders to the nervous system. It translates incoming sensory information and gives directions based on past experiences and the current environment. PNS covers parts of the nervous system outside the CNS. It includes the cranial and spinal nerves which extends from the brain and spinal cord of the human body. Spinal nerves transports impulses to and from the spinal cord; yet, cranial nerves

Integumentary System, happens to be one of the most fascinating systems of the body, and contains the largest organ, being the skin itself. Three layers make up skin which are the Epidermis (epi meaning upon or above) the outer most layer, the dermis which is the middle layer and lastly, the subcutaneous or the hypodermis (hypo meaning below). Hair, one of the things that are included in the system and if helps with the regulation of body temperature. Nails help protect the end of the fingers and toes because if not there would be exposed skin. Lastly, we have the glads which are the sudoriferous (eecrine and apocrine) or the sweat glands and sebaceous or the oil glands, they are help with the protection and the regulation of body temperature in the Integumentary system, which truly when you read about it makes it so interesting. It is always growing and making new cells, and tissues.

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.

The nervous system is in many ways the most vital system of the body. It is responsible for monitoring and regulating homeostasis, coordinating voluntary and involuntary responses and integrating sensory information. Anatomically, it is divided into two sections: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS controls the brain

The nervous system is a multiplex web of nerves and cells that carry information from the the brain (spinal cord) to the rest of the body. The nervous system has two main parts: the central nervous system and the peripheral nervous system. The central nervous system contains the brain and spinal cord. The peripheral nervous system consists of the nerves, which relay the messages from the central nervous system to various parts of the body via electrochemical means.
