The Nervous System: The Nervous System Of The Human Body

The nervous system is the body's decision and communication center. The central nervous system (CNS) is made of the brain and the spinal cord and the peripheral nervous system (PNS) are made of nerves. The brain is made of three main parts which are the forebrain, midbrain, and hindbrain. The forebrain consists of the cerebrum, thalamus, and hypothalamus. The midbrain consists of the tectum and tegmentum.

In each tissue, the endocannabinoid system performs different tasks but the overall aim is the same. This is that of homeostasis (TruthOnPot.com, 2013). Homeostasis is the control of a stable internal environment. The endocannabinoid system is a unique system in the brain that affects important functions such how a person feels, moves and reacts (The Science of the Endocannabinoid System, 2011).

The auditory nerve, much like the optic nerve of the visual system is composed of ganglion cell fibers. In the case of the auditory system, these fibers originate from ganglion cells in the spiral of the cochlea.112 The fibers of the auditory nerve carry signals to the brainstem where they then synapse with neurons within the cochlear nucleus. Information from the left ear is transmitted to the left cochlear nucleus and information from the right ear to the right nucleus, however, much like in the visual system, many of the fibers that leave the cochlear nucleus cross over to deliver signals to the contralateral side of the brain.112 The area of the brainstem that is believed to process information about where sounds are coming from, the superior olive to be exact, receives input from fibers on both sides of the nucleus.112 The auditory system differs from the visual system in that in the auditory system, the cochlea is unable to produce an exact placement of the location of a stimulus, whereas the retina, within the visual system, can directly identify where a stimulus originates.114 This, again, is where the superior olive comes into play computing very small time differences between the signals that arrive in each of the

The Mudra therapy is a very unique concept and it deals with the stimulations of the nerves in the hand and the brain. The nerves play a very major role in the concept of Mudra therapy. The nerves in the hand get stimulated on holding a particular hasta mudra; they travel via the spinal cord and reach the brain. The brain gets stimulated and sends impulses to the respective parts of the body, depending on the fingers involved in holding the hasta mudra, as each finger in the hand corresponds to a particular part in the body. Hence the knowledge of the nervous system of the hand is required to understand the therapeutic effect of the hasta mudras effectively.

TAQ 1: a) b) The mammalian nervous system is split into two. The central nervous system consists of the brain and the spinal cord, which coordinates and controls the movement and activities of the body and the peripheral nervous system, made up of the somatic and autonomic system, which forms the connections between the organs and the central nervous system. The brain and the spinal cord work together to aid the coordination of the body.

All these components can be easily purchased off-shelf. In contrast, gene editing tools such as zinc finger nucleases cost approximately five thousand dollars, and their use require professional laboratory equipment, making it even more expensive. Thirdly, CRISPR works incredibly quickly. Thermo Fisher Scientific states that Cas9 takes at most three days to identify and cut the target DNA. In other gene editing techniques, such as TALENS, custom proteins need to be produced by scientists for each different segment of DNA targeted.

The diencephalon, alongside the cerebrum make up the two major divisions of the forebrain. The main structures of the diencephalon include the hypothalamus, thalamus, epithalamus (including the pineal gland), and also the subthalamus. Moreover, located within the diencephalon is found the third ventricle, which is one of the four brain ventricles or cavities filled with cerebrospinal fluid. The function of the diencephalon is to relay sensory information between brain regions and control many autonomic functions of the peripheral nervous system.

They have the ability to transmit the signals among the nerve cells. They had known as neurons. Also, communicate the information throughout the body and brain. The brain utilizes neurotransmitters to inform the lungs, heart and stomach to do their functions. Those like, lungs to breath, heart to beat and stomach to digest.

Introduction Brain to Brain Interface (BBI) has been made likely as the way brain cells interact with each other. A process is known as synaptic transmission in which cell to cell communication occurs, chemical signals passing among cells ensuing electrical spikes in the other or the receiving cell. Synaptic transmission formulates the base of all brain activity, these activities are motor control, memory, observation, and emotion. Since cells are linked together in a network, brain activity produces a harmonized pulse of electrical activity, which is called a brainwave. Changing in the brain waves conferring to the perceptive procedures that the brain at the present time is working through and are characterized by the time-frequency outline of the up and down states or oscillations.

It ranges from a snap and lip twitching, to eye movement. As nurses, it is important to be sensitive and considerate that there’s more to observe on a patient’s overt body

Five Critical Thinking Questions 1. How do neurotransmitters function? Neurotransmitters are chemicals located in synaptic vesicles. These chemicals are inside neurons and convey information.

Biofeedback is the use of instrumentation to bring physiological events to conscious awareness. It overall allows you to see what you muscles are doing in a quantified way and learning from that. There is also electromyographic biofeedback, which permits awareness of neural recruitment of muscles by transducing the electrical activity during muscular contraction into audio or visual signals. This is a way to look at how outside signal will be affecting you neural recruitment of your muscles. You can enhance your ability to check visual feedback by using mirrors with your original test.

It also has parts that are important for the level of consciousness and for sleep.

The Somatic nervous system has two neutrons. Those two neutrons are sensory neurons and motor neurons. The sensory neurons job is to carry information to the central nervous system. The motor neurons job is to carry information from the brain and spinal cord to the muscle fibers throughout the

The hypothalamus communicates to each lobe differently. The hypothalamo-hypophyseal tract system is the specific way the hypothalamus communicates with the posterior lobe of the pituitary gland. It is a nervous system connection with direct connecting neurons. The neurons are located in the hypothalamus and then axons extend down to the posterior lobe of the pituitary gland. The neurons produce hormones that slide down the axons and end up in the posterior lobe.
