Anatomy and Physiology
The body system that I have chosen is the Nervous System. The nervous system is a complex network of nerves and cells that carry messages to and from the brain and spinal cord to various parts of the body. It has three main functions: an interpretative function, a sensory function and a motor function. The sensory function gathers information from inside the body and the outside environment, than the Sensory information is brought to the central nervous system (CNS) and is than processed and interpreted. The motor function finally conveys the information from the central nervous system (CNS) and travels it to the muscles and glands in the body. The nervous system also consists of three small systems in the one big system. …show more content…

The brain is the “powerhouse” of the nervous system and the body in whole. The brain and spinal cord are included in the (CNS) both are covered in hard like bone to ensure their protection because these are such delicate and very important parts of the body and its functions. Included also in the nervous system is what’s called cells. Cells are microscopic units that each plays a vital role in the growth, development and day to day maintenance of the body. These cells are found everywhere in the body, many cells include blood cells, bone cells, immune cells etc. Each and every cell is used and needed to function the nervous system. The nervous system also contains an organism called nerves. It is made up of 4 major nerve families- the cervical nerves, thoracic nerves, lumbar nerves and sacral nerves. These nerve groups are spread across all areas of the body each and every one holds energy which it sends signals to and from the brain. Nerves control our emotions, feelings, actions and thoughts. The nerves send messages to the brain and down the signal cord which then tells your muscles to move a certain way or do a certain thing. All nerves are connected to either your brain or your spinal cord. From here they then branch off to different areas of the body, this is where the different types of nerves come in. When nerve cells are bunched together to create a body on which the nerve fibres break off into separate parts from one main point this is called a ganglia. These are a part of the (PNS) and lay near the major attach parts on the spine. The ganglia form a breakaway point of which the nerves branch off throughout the body. A final component of the system is the digestive tract. This comes in play when the (ENS) recalls to the regulation of the digestive system, the digestive tract is involved in the function of the body’s organs and glands it
