Nervous System Response Paper

Among various types of organ systems, the nervous system is one of the most important one in human body. It is responsible for producing, controlling and guiding our thoughts and responses to the world around us according to James W. Pennebaker (2012). During embryological development, the cells that form nervous system are incredibly specialised and work complexly than the cells that form skin or other body parts. Neurosecretory cells are one of the examples of specialised nervous system cells that produce neurosecretions. Neurosecretions are hormones which carry information from sensor cells to target cells and they can be released directly into the bloodstream

The components of the nervous system involved in the skeletal muscle movement is the motor division. The motor impulse moves through the body by traveling through efferent fibers. A motor unit is a neuron and also that is where all the other muscle fibers are connected.

The somatic nervous system controls the contractions of skeletal muscles and is under voluntary control.

The Central nervous systems include the brain and spinal cord which transfers voluntary nerve impulse to skeletal muscles, skin, muscles, and glands.

Our nervous system is there to help to transfer the things our body feels and what we need. The nervous is broken up into two parts, the central nervous system (CNS), and the peripheral nervous system (PNS). The CNS controls the brain and the spinal cord, the PNS controls the nerves and the ganglia (a small mass of gray matter). Our body uses the spinal cord to send messages to the nerves so that it can control our organs and muscles.

The nervous system is composed of two separate systems: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS includes the brain and spinal cord while the PNS consists of the nerves that are outside of the brain and spinal cord. The brain receives information sent from the PNS via neurons. The CNS contains neurons which are the basic units of the nervous system. There are three different classifications of neurons: motor, sensory, and interneurons. The motor neurons transfer signals from the central nervous system to the muscles to help with movements. Sensory neurons transfer information to the central nervous system from external stimuli such as environmental factors. The interneurons transfer signals between the motor and sensory neurons. If a person is diagnosed with Parkinson’s the neurons that receive the information begin to fail and eventually die. A person that does not have sufficient amount of neurons is not able to receive dopamine and begin to lose coordination thus limiting their movement.

The peripheral nervous system, or PNS, is the part of the nervous system responsible with carrying sensory information (a person’s senses) and motor information (a person’s coordination) to and from the central nervous system (CNS, the part that takes the information and applies it to the body), as well as throughout the whole body. Both parts of the nervous system are made up of nerve cells, or neurons, which carry the electrical impulses that contain the information sent between the PNS and CNS. The neurons

These are only some examples the muscle system does. In the video, talked about the muscles cells that are also known as muscle fibers. Each muscle fiber is surrounded by an excitable membrane called a sarcolemma and bundles that receive signals from the nervous system that contact them creating force and motion; this produces almost all the movements. The skeletal muscles are connected to the somatic nervous system. This gives control to the person over their movements. In the video, “How your muscular system works,” it also went over the fast fibers and slow fibers. Fast fibers react very quickly, but it easily fatigues. On the other hand, slow fibers are slow to react and slow to fatigue. The video also mentioned the Autonomic Nervous System and that the cardiac muscle and smooth muscle. The Autonomic Nervous System contracts and relaxes the smooth muscle. For example, it pushes food through the digestive system. Also, The Autonomic Nervous System contains cardiac muscle that supplies the heart with blood and

The musculoskeletal involves the muscles and skeletal system which consist of bones supporting the bodyweight. The muscles and bones help in movement and maintaining body position through the physiological process of contraction and relaxation, muscles pulling on the bones. The skeletal systems also consist of cartilages and ligaments important for bone connection and stability with connective tissue. The muscles get attached to the bone by the connective tissue enhancing contraction and relaxation in movement. The muscles contain long muscle fibers responsible for the contraction and relaxation. The fibers contain bundles some of which allow slow movement described as slow twitch and fast twitch which ensure fast movement. The process of movement involves coordination between the musculoskeletal system and nervous system. In the process of muscle contraction to enhance movement the following takes place.

Sympathetic Nervous System: Mobilizes bodily resources to respond to the stressor. Emergency response is often called fright or flight response.

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 peripheral nervous system (PNS) is connected directly to the central nervous system, and consists of neurons and nerves that send information back and forth the CNS. Furthermore, the peripheral nervous system can be divided into two sections, the sensory nervous system and the motor nervous system. The Sensory The sensory nervous system is in charge of transmitting data from a variety of internal organs or from external stimuli to the central nervous system using sensory nervous cells. On the other hand, the cells of the motor nervous system (motor neurons), take the impulse from the CNS to effectors, which include glands and muscles. In addition, the motor nervous system can be further divided into the somatic nervous system, controls voluntary actions of the skeletal muscle and external sensory organs, whilst the autonomic nervous system operates

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.

The two components of the central nervous system (CNS) are the brain and the spinal cord. Communication between the brain and the spinal cord happens through motor neurons, which are nerve cells that enable motor movement. Each motor neuron is made up of a cell body, which holds all the cell components, dendrites which send information it receives to the cell body, and an axon which sends nerve impulses to the muscle (Porth & Matfin, 2009). As electrical impulses are sent through the motor neuron, it stimulates the muscle fibers in the body to move. This is the process in which motor function happens. Therefore, the basic abilities to breathe, speak, swallow, walk and button a shirt are

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.
