Sensory System

Even though the brain is the major control center if the body, its job would not be possible without the spinal cord. The spinal cord is the major organ that helps information travel between the body and the brain. Nerves branch in the peripheral system from, either the brain stem or spinal cord, each nerve attaches to a specific area of the torso and limbs it 's responsible for communication to and from those regions. There are three very important

For this essay, I decided to talk about the nervous system. The nervous system “The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body”(Inner body). These organs work together in control of the body and communication between the parts. The brain and the spinal cord combine together to control the center, which is known as the Central Nervous System (CNS). The Central Nervous System is where the information is evaluated and decisions are made. The sensory nerves and sense organs of the peripheral nervous system (PNS) control the conditions inside and outside of the body and they send information to the CNS.

The most dominant sensory system is the visual sensory system. In the case of humans, vision is the dominant sense for various reasons. While auditory, olfactory, and tactile sensory systems are important in their own respect, the visual sensory system takes up a large portion of the human brain. The occipital lobe is primarily responsible for the visual sensory system, and it is one of the four major lobes of the human brain. In addition to the occipital lobe the thalamus, brainstem, dorsal system, and the eye, are also involved in the detection, analysis, and perception of vision (Carlson, 2007). No other sensory system uses as much of any other lobe than the visual sensory system uses the occipital lobe. The human eye is also very complex. The eye relies on rods to maintain vision in low light, and cones to for color perception and high spatial acuity (Carlson, 2007). The eye’s retinal circuitry involves a photoreceptor layer, which contains the rods and cones; a bipolar cell layer, which contains bipolar, amacrine, and horizontal cells; and a ganglion cell layer, which contains ganglion cells. With that being said, physiologically, the vision sensory system if the dominant system.

The skeletal system which performs important function such as support, movement, blood cell production, calcium storage, as well as endocrine regulation. The nervous system consists of CNS which is composed of the brain and the spinal cord, and consists of PNS which are the main control centers for all body activities. The skeletal and nervous systems work together to function correctly. For instance, the nervous system sends signals to the skeletal muscle to contract which causes the skeletal system to react and move.

The sensory system is a part of the nervous system. It is responsible for processing our sensory information, and it is the way in which we make contact in our everyday lives through our five senses – sight, touch, hearing, smell and taste. (IML Training, 2012) Our sensory receptors allow us to pick up information – ears, eyes, nostrils, tongue and skin. All senses evolve to collect their distinct type of information about our environment and to inform us of our status within it. (Goldstein, 2009)

The muscular system works closely with the nervous system. The brain knows the body position because of receptors in muscles. The nervous system also regulates how fast smooth muscles digest food.

Every move that our bodies make, thinking about a film you saw last night or an essay you need to write for school, shaking off a little bug from the leg, deciding between two things or drinking tea after it cools a bit, every action, reaction is driven by our nervous system. All the information taken in is processed and executed by electrical and chemical signals to and from nervous cells. The nervous system controls all our physiological and psychological reactions. All animals have nervous system, except for very simple ones like sponges (The Nervous System, 2015). Human’s nervous system is probably the most complex one, all of our thoughts, emotions and actions are based on the three principle functions: sensory input, integration,

There are eleven systems in the human body which one of them is known as the nervous system. Like most systems in the human body, the nervous system is composed of organs such as the brain, spinal cord, nerves and ganglia. The nervous system has been known to be the bodys primary communication and control system.

Due to fewer serious side effects and reduced cost, exercise intervention is considered as an attractive alternative to medication. Moreover, it facilitates in improving balance and fall reduction.

The peripehal nervous system is broken into two brances which include the somatic nervous system and the autonomic nervous system. The somatic nervous system transmits the messages between the central nervous system and your sensory organs. It regulates movement, posture and balance. It contains your sensory and motor neurons. Once messages are transmitted through sensory neurons our brain can interpret the picture you are seeing in front you you, the food you are tastign and even a hot flame touching your finger tip. Once the message gets to the CNS it sends messages back through the motor neuron that controls movements. It has voluntary control. For example, if you touch a flame, the sensory neuron from your finger tip will send the message that it is hot and your brain will deliever a message back to move your finger. It happens almost instantly. The other branch which is the autonomic nervous system controls the internal body processes. You body does these things automaticallt without having to think about it. Although, you could still have control over some of the processes, such as breathing. The ANS is broken into two different parts which is the sympathetic nervous system and the parasympathetic nervous system. The sympathetic nervous system speeds up bodily processes. It is considred an “alarm

It is well established that the aging process adversely affects a number of neurocognitive functions. Increasing our understanding of the neurocognitive aging process remains a significant public health issue. A large body of cross-sectional data (Anstey, Lord, & Williams, 1997; Anstey, Luszcz, & Sanchez, 2001a; Anstey & Smith, 1999; Baltes & Lindenberger, 1997, 1997; Lin et al., 2011; Lindenberger & Baltes, 1994; Salthouse, Hancock, Meinz, & Hambrick, 1996) and longitudinal data (Anstey, Luszcz, & Sanchez, 2001b; Lin et al., 2014) has demonstrated age-related declines in sensory functions that often happen in tandem with declines in cognitive ability. Age-related declines in sensory functions also profoundly affect quality of life (Carabellese et al., 1993).

To work on the athlete balance stabilization, a few exercises can be implemented into their training program. Some exercises consist of single-leg balance progression, single-leg balance reach progression, and single-leg balance with dynamic movement progression. These exercises can help assist in the sensitization of muscles spindles leading to improvements in neuromuscular efficiency (Clark, pg. 216).

The differences between male and female brains and how the work have been a very controversial subject in the science world even in present time. In my project featuring the science of Neurology, the study of the human brain; I will undergo an experiment to see whether male or female have a faster sensory response time. Sensory response, or ASMR (Autonomous Sensory Meridian Response), is the response in the brain sorting gathered information of sensory such as touch, smell, hearing, taste, and sight by relevant and irrelevant information. The response time is the speed differences in the male and female brain in how it gather the information, sort it, and react to what is given, (Google Search, N.D.). In easier term - My experiment will

Sensory processing (SP) refers to how the central and peripheral nervous systems manage incoming sensory information, including the reception, modulation, integration, and organization of sensory stimuli (Miller et al., 2000). Based on the work of Ayres, Dunn (1997; 2001) developed a model of sensory processing. According to Ayres (1995), senses provide information about the body and surrounding environment to the brain which then organizes and integrates the sensory input. Well organized sensations are believed to contribute towards the formation of perceptions that facilitate behavior and learning. In contrast, poor organization and integration of sensation will result in learning difficulties and behavioral problems (Bundy et al., 2002; Schaaf et al., 2010). Sensory processing disorder refers to a set of impairments where sensory information is not adequately processed in the brain resulting in different functional difficulties in many aspects of the daily lives of the affected persons.
