Human nervous system is divided into the Central Nervous System (CNS) and the Peripheral Nervous System (PNS). The CNS contains the brain and the spinal cord and it is responsible for receiving and processing information; initiating actions. On the other hand, The PNS consists of sensory and motor neurons; also it has two parts the somatic system and the autonomic system and its main role is to transmit signals between the CNS and the rest of the body. Human nervous system receives information from internal environment (our bodies) and external environment through our five senses, hearing, vision, smell, taste and touch. Also our system responds to different type of stimuli (response caused by a change in an organism’s environment) consistently. …show more content…
Discriminative touch and proprioceptive information carried and processed from the body through medial lemniscal pathway to the cerebral cortex which requires three type of neurons, first order neuron that carries action potentials from the receptors ( the hand and the eyes) into brain stem or spinal cord, second-order neuron to carry action potentials from the brain stem or spinal cord to the thalamus and third-order neuron to carry action potential to the somatosensory area in the cerebrum or the cerebellum . The vestibular system is important to maintain balance, sensory information sent over the Medial Longitudinal Fasciculus (MLF) to the occulomotor nuclei, descending tract sent back through the medial vestibular to control head movement and amalgamate head and eyes …show more content…
Action potentials originate in the motor cortex that controls voluntary skeletal muscles movement on the opposite side of the body where the lower motor neurons arise. So to complete a swing, it is necessary to know various kind of information from the various lobes in the brain, information from the frontal lobe about the goal to be achieved and the required strategies to achieve that goal, the temporal lobe where motor cortex receives information about memories of past methodologies followed in softball training; add on information about the initial starting point of the limb as well as any applied forces to the limb; this type of information is provided by muscle spindles and Golgi Tendon Organs (GTO). After receiving all that kind of information, the motor cortex descends singles through direct motor pathway (Croticospinal) that consists of three types of neurons, upper (Motor cortex to brain stem or spinal cord), interneurons (Brain stem or spinal cord to lower neuron), lower (excite muscles in head and body) to control voluntary movement of limb (swing). Or indirect motor pathways (Medial or Lateral) to maintain balance, response to visual stimuli or regulate muscle tone. The motor nerve stimulates the required
The nervous system controls both voluntary action (like conscious movement) and involuntary actions (like breathing) and sends signals to different parts of the body. The central nervous system includes the brain, spinal cord, sensory organs, and all of the nerves that connect these organs to the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts. The brain and spinal cord form the control center, also known as the central nervous system, where information is
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 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.
Let’s say that there is a mechanical sense. If someone touched your hand, your somatosensory system will detect various stimuli by your skin’s sensory receptors. The sensory information is then conveyed to the central nervous system by afferent neurons. The neuron’s dendrites will pass that information to the cell body, and on to its axon. From there it is passed onto the spinal cord or the brainstem. The neuron's ascending axons will cross to the opposite side either in the spinal cord or in the brainstem. The axons then terminates in the thalamus, and on into the Brodmann Area of the parietal lobe of the brain to process.
Second, the nervous system then processes and interprets the sensory input. And finally, the third fundamental function of the nervous system is to acknowledge appropriately to the sensory input.
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 within it.
Neurobiology is a theory that deals with the brain and your nerves. It determines if you are a left or right brain person. One of the theorists is named Roger Sperry. He was a very big neurobiologist. A disease that deals with this theory is ADD/ADHD.
Breaking Stereotypes: The Diverse World of Male Strippers in Nashville Even though it is commonly referred to as "Music City," Nashville is not only a center for honky-tonks and country music concerts. Male strippers are redefining attitudes and defying preconceptions, and beneath its bright surface lies a community of male strippers that is diverse and active. Within the scope of this essay, we go into the multidimensional world of male stripping in Nashville, examining the people, stories, and reasons that are behind this fascinating industry. 1. What is the difference between a. and a. Beyond the Clichés: Diverse Backgrounds Contrary to popular belief, male strippers in Nashville come from a wide array of backgrounds.
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.

The human body is divided into many different parts called organs. All of the parts are controlled by an organ called the brain, which is located in the head. The brain weighs about 2. 75 pounds, and has a whitish-pink appearance. The brain is made up of many cells, and is the control centre of the body. The brain flashes messages out to all the other parts of the body.
The human body is very complex. It is like a job. You have to do a million things in one day to make it through the day. The body uses nine systems to do all of those jobs. They all have separate functions, but some work together. Each system is also made up of organs. There are many ways to care and protect the systems from the many different problems they can have. There are also many interesting facts about each system.
Within the human anatomy, an intricate and complex network of specialised nerve fibres and neurons works in collaboration with the central nervous system and peripheral system, designed to carry out the various actions humans perform every day. The nervous system is also known as the master control unit of the human body, as it operates other major functions such as the circulatory and respiratory systems (Jakab, 2006). It is composed of the central nervous system (CNS) and the peripheral nervous system (PNS). The neurons established within the various sections of the nervous system, is structured with three main parts: a dendrite which is a cluster of branches that operates by receiving information from the receptor and neurons and transferring nerve impulses to the cell body; furthermore, a cell body is composed of a nucleus, that works to provide energy and nutrients for the neuron; lastly is an axon, electrically conducted by the myelin sheath, the axon is a pathway nerve impulses pass through from the cell body. In addition, this is the process in which nerve impulses travel by to be able to access the rest of the system (Core Science, 2010). The correct function of the nervous system is vital to the daily survival of an individual, as it obtains a significant role in the control and co-ordination of the human body. Furthermore, if a situation occurs where the nervous system dysfunctions or develops a disease (such as multiple sclerosis), it would in that case threaten the current status of one’s health and cause havoc in the system.
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 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 even blinking. It is made up of nerve tissues to receive and transmit stimuli to nervous centers and initiate response. Neurons are nerve cells that transmit signals from one location of the body to another. With damage to the nervous system the body would not be able to function properly. The body has to be well taken care of in order to insure proper regulation. The two anatomical divisions that work hand in hand to help regulate the nervous system are the central and peripheral nervous system. According to the Campbell’s seventh edition biology book the nervous system is the most intricately organized data processing system on earth. It is a complex collection of nerves and specialized cells.
The sensory system is not a system by itself in the human body; it is actually a sub system or a part of the nervous system. When sensory receptors/neurons from the sensory organs detect a stimulus, this information is sent to the brain through sensory neurons and the reaction to that stimulus is sent back to that area of the body where the stimulus was present. Another strong relationship between the nervous system and the sensory system is that there are parts of the brain (the brain is part of the central nervous system) that are involved in sensory perception such as thalamus as well as the lobes of the brain such as the parietal lobe (this is mainly involved in the senses of smell, touch, and taste).
