Nervous System Outline

The central nervous system (CNS) is the processing center for the nervous system. It receives information from and sends information to the peripheral nervous system. The two main organs of the CNS are the brain and spinal cord. The brain processes

The respiratory and cardiovascular systems work together to supply oxygen to the body’s cells, remove carbon dioxide and regulate the Ph of the body’s fluids. This system of regulation is called homeostasis. (www.wiki.answers.com, 2013)

The esophagus receives food from the mouth after swallowing and then delivers it to the stomach. The stomach holds food which it is being mixed with enzymes which continue the process of breaking down the food into a useable form. When the contents of the stomach are processed they are released into the small intestine. In the small intestine food is broken down by enzymes released from the pancreas and bile from the liver, the food is moved through and mixed with digestive secretions. The small intestine is made up of three segments the duodenum, jejunum and the ileum, the jejunum and the ileum are mainly responsible from the absorption of nutrients in to the bloodstream. These contents start out semi-solid and end in a liquid form after passing through the organ. Water, bile, enzymes and mucous change its consistency, one the nutrients have been absorbed it then moves onto the large intestine. The large intestine connects to the rectum and is specialised in processing water so that emptying the bowels is easy.

Veins and arteries- The arteries are perceived as caring oxygenated blood to the tissue and the veins carry deoxygenated blood back to the heart.

Many of these have elements that maximise or increase the surface area. The human body is a specialized organism that has many body systems working together to provide the necessities to survive. The five main systems are circulatory, respiratory, digestive, excretory, nervous and hormonal. The circulatory system is responsible for transporting blood through the body. It is pumped by the heart through the arteries and capillaries to the individual cells, where O2 and nutrients are exchanged for CO2 and other waste products. In the veins, transported back to the heart, CO2 gets eliminated after reaching the lungs/respiratory system. The respiratory system provides the body with oxygen, and eliminates CO2, its main organ is the lungs. The digestive system takes in food and fluids to supply the body with nutrients, which are made usable and then absorbed. The non absorbable leftovers and the waste get eliminated from the body. Important organs of the digestive system are the stomach, intestines, pancreas, and liver with the gallbladder. The excretory system eliminates ammonia/nitrogen waste. Main organs are the kidneys, ureter, bladder, and urethra, which concentrate, channel and store the urine. The nervous system controls the body, as well as the senses. The main organ is the brain and spinal cord, the essential nerve cell is called a neuron. The human body connects to evolution

Role in Body: The digestive system is responsible for digestion (mechanical + chemical), absorption, and movement along GI tract.

The digestive system is one of the body’s largest systems (about 8-10 metres long) and it is made up of a series of organs and glands. Its processes include: food ingestion, enzyme secretion, digestion, absorption and defecation. Its organs form the gastrointestinal (GI) tract.

The peripheral nervous systemcontrols all voluntary amd involutary muscles and glands. Peripheral nervous system contains all your nerves amd nerve bundles excluding the brain and spinal cord. The Central spinal cord. The CNS receives sensory infpormation from the nervous system and controls the body's responses. The diffrence between peripheral and central nervous system are th CNS, collections of neurons are called nuclei. In the PNS, collection of neurons are called ganglia. another diffrence would be the CNS, collections of axons are called tracts. In the PNS, collections of axons are called nerves.

The nervous system is made up of two sections, the Central Nervous System, which is composed of the brain, cerebellum, and the spinal cord. Whereas, the Peripheral Nervous System contains nerves that allows your body to move, also known as sensory and motor nerves.

Peripheral Nervous system- Consists of the Cranial nerves, Spinal nerves, and Autonomic nervous system (ANS).

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

The peripheral nervous system is abbreviated as PNS. This system is the part of the nervous system that consists of the nerves and ganglia on the outside of the brain and spinal cord. In this system the nerves extend from the brain and the spinal cord. Two nerves that are included in the peripheral nervous system are spinal and cranial nerves. The spinal nerves carry impulses to and from the spinal cord. The cranial nerves carry impulses to and from the brain. The function of the peripheral nervous system is to serve as a communication lines among sensory organs, the brain and spinal cord, and glands or muscles. This system consists of mixed, sensory and motor nerves. The mixed nerves consists of both sensory and motor nerves. The sensory nerves run from stimulus receptors that inform the central nervous system of the stimuli. The sensory nerves are considered afferent. The motor nerves run from the central nervous system to the muscles and glands, called effectors that take action. The motor nerves are considered efferent. The peripheral nervous system is split into the sensory-somatic nervous system and the autonomic nervous system. The sensory-somatic nervous system consists of twelve pairs of cranial nerves and thirty-one pairs of spinal nerves. This nervous system transmits sensory information from the body to the brain and motor movements from the brain to the body. The autonomic nervous system is the

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

The part of the nervous system encompasses the brain and spinal cord. There is both white and grey matter in the central nervous system (CNS). Its main function is to send, receive and interpret motor, sensory and cognitive information around the entire body.
