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.

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
The first basic function of the muscular system is movement, which is carried out by the skeletal muscles. The primary function of the skeletal muscle is to produce voluntary gross and fine motor movement. This set of voluntary muscles provides the forces that enable the body to move. A skeletal muscle links two bones across its connecting joint. When these muscles contract or sho...
Sensory neurons behave to physical stimuli such as light, sound and touch and send observation to the central nervous system about the body’s surrounding environment. Motor neurons, based in the central nervous system or in peripheral ganglia, disseminate signals to mobilize the muscles or glands.
A bunch of nerves put together is called the Nervous system. The Nervous system helps with body coordination and provides sensory information about external problems. The nervous system controls the brain, spinal cord, sense organs, etc. Without our nervous system, we would not be able to function, since
When a message comes to the brain from body parts such as the hand, the brain dictates the body on how to respond such as instructing muscles in the hand to pull away from a hot stove. The nerves in one’s skin send a message of pain to the brain. In response, the brain sends a message back dictating the muscles in one’s hand to pull away from the source of pain. Sensory neurons are nerve cells that carry signals from outside of the body to the central nervous system. Neurons form nerve fibers that transmit impulses throughout the body. Neurons consists of three basic parts: the cell body, axon, and dendrites. The axon carries the nerve impulse along the cell. Sensory and motor neurons are insulated by a layer of myelin sheath, the myelin helps
All organ system work together; in order to keep and support the conditions that the cells, tissues, and organs need to function properly. Each organ system has an important function in the body. There is one system that is not as well known as other; it is the integumentary system. Most people know the organs of the integumentary system, but they do not know that these organs work together to form this 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 the 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. Nerve cells generate electrical signals to transmit information.
Our nervous system interacts with every other system in your body. The endocrine system works with our brain and central nervous system, to control the creation of specific hormones and enzymes. The digestive and excretory systems work with the nervous system in a conscious and unconscious ways. We can't tell our stomach where the food goes after we ingested it. The body is programed to function voluntarily and
The muscular system is an intricate system that if affected can seriously affect the quality of daily living as well as total life span. Covering the entire body the muscular system consists of skeletal, smooth, and cardiac muscle. And within the three muscle groups five basic functions are executed: movement, protecting vital organs, pumping blood, aiding digestion, and ensuring blood flow. None of these important tasks would be possible without a healthy and strong muscular system.
The brain and spinal cord make up the central nervous system. The brain doesn't just control your organs, but also can think and remember. That part of the brain is called the mind.
When an action potential travels down an axon and reaches the axon terminal, it triggers the release of neurotransmitter from the cell. Neurotransmitter molecules cross the synapse and bind to membrane receptors on the adjacent cell. Other synapses are electrical; in these synapses, ions flow directly between cells. A single neuron can’t do very much by itself, and nervous system function depends on groups of neurons that work together. Individual neurons connect to other neurons to stimulate or inhibit their activity, forming circuits that can process incoming information and carry out a response.
The nervous system is a network of cells that take messages from the brain and spinal cord to other parts of the body. The nervous system is made up of the Central Nervous System and the Peripheral Nervous System. The Central Nervous System has two main parts; the brain and the spinal cord. While the Peripheral Nervous System has the Somatic and the Autonomic Nervous systems included with in it.
The nervous system is composed of all nerve tissue in the body. This organ system forms a communication and coordination network between all parts of the body. It plays a major role in everyday activities such as breathing, walking, and even blinking. It is made up of nerve tissues to receive and transmit stimuli to nervous centers and initiate responses. Neurons are nerve cells that transmit signals from one location in the body to another.
The sensory system’s organs are the sense organs of the body. The purpose of the sensory system is to allow us to experience outside stimuli and identify alterations in the environment by sensory receptors and eyes, nose, ears, tongue, and skin, which are the sensory organs. The sensory system is actually one of the main elements of the body used to process sensory information.
Nervous system is one of the major organ systems that is responsible for the coordination of biological activities inside the body through cells called neurons. It is composed of the brain and spinal cord which are surrounded by protective layers of bone and membrane tissues called meninges. There are two major divisions in the nervous system; first one is the central nervous system (CNS) and the other being the peripheral nervous system (PNS). The CNS is composed of the brain, spinal cord, and retina while the PNS includes the sensory neurons, ganglia, and connecting neurons. The nervous system applies control using nerves; almost as if sending a message by a telephone. The nervous system is fast due to its electrical nature. The nerve cells in this system are connected with each other in a complex manner where the neural pathways would be possible. Neural
The nervous system’s main function is to coordinate all of the activities in the body. The main organs are the cerebellum, which controls and coordinates movement. The cerebrum, is the center for conscious thought, learning, and memory. The last main organ is the brain stem. The brain stem keeps the automatic systems in your body working. Problems of the nervous system include, epilepsy, Alzheimer’s, and multiple sclerosis. You can care for your nervous system by wearing a seatbelt, wearing a helmet, and by not using drugs or alcohol. Something very confusing about the nervous system is that the left side of human brain controls the right side of the body and the right side of the brain controls the left side of the body!
