Suggest Two Ways That Relax Reactions Help Maintain Homeostasis

This week I was able to practice in relaxation techniques with my patient. The patient was benefited from this technique and helped him to manage his stress. Late in the afternoon we joined another relaxation technique and helped patient to relax.

Neurons transmit information to each other and to muscles, organs and glands. The nerve impulse is sent from the axon of one neuron to the dendrite of another neuron. The neuromuscular junction as labeled in Part A of this assignment, shows that there is a space between the axon of a neuron and the motor plate of the muscle cell. The two parts do not actually touch each other. When the football player’s brain sends a message to move during the game, the nerve impulse is sent from neuron to muscle cell. The space (synapse) between the axon of a motor neuron and a muscle cell is called a neuromuscular junction. The axon of the motor neuron contains synaptic vesicles which contains thousands of molecules of the neurotransmitter acetylcholine. This acetylcholine is released into the space between the axon and the muscle cell. The muscle cell membrane has receptors to accept or to bond with the acetylcholine. This region is called the motor end plate. When the acetylcholine bonds with the protein receptors in the motor end plate, sodium and potassium gates in the region open at the same time

Often called the fight or flight reflex, stress has been known to save people’s lives, whether it be on a battlefield or some dangerous situation back home. Too much stress ultimately leads to health problems, but too little stress isn’t good for us either. When we go too long without a sharp stimulating response, the body loses its ability to handle stress properly (Tom Scheve, 2009). Somewhere between too much, and too little stress can actually be good for you, helping you perform under pressure. It is when someone cannot turn off that fight or flight feeling that it begins to show its negative effects. Ranging from lack of concentration and sleeplessness to depression, PTSD and suicide, prolonged exposure to stress can be

Post Traumatic Stress Disorder is very serious issue when it comes to war veterans. However it is abused by many people in an attempt to fraud the government for personal gain.

If we imagine that an individual has begun exercising, the oxygen uptake increases because there is a higher demand for energy. Oxygen is the ultimate source of energy that allows ATP to be generated. More ATP must be made in order for homeostasis to be maintained. After a prolonged period of exercise, lactic acid accumulation begins to occur in the tissues of the body because the energy for oxygen uptake can no longer be supplied after a certain period of time of exercise. When the individual ends exercising, it takes time for the oxygen uptake to return to its resting level because the lactic acid that had accumulated in the tissues must be broken down into CO2 and H2O. The individual breathes deeply during this time because heavy breaths of oxygen must be taken in for the lactic acid to be broken

The cognitive level of analysis aims to study how the inner processes of the mind processes information gained, and how they are interpreted and applied into the real world. Within this level of analysis, it was found that the cognitive and biological factors of our mind influence how we feel, or in other words, our emotions. Emotion can be defined as the body’s response to any specific situation. As all human beings can express how they feel through facial expressions, this suggests that emotions are biological rather than cognitive. However, emotions can be dependent on both the cognitive and biological factors of our body. Cognition is defined as the mental processes of obtaining and processing knowledge through experiences and information gained from our surroundings whereas biology is the study of the internal and physiological mechanisms of behavior of living organisms. There is a set of theories of emotion psychologists came up with in order to explain how the two factors interact in emotion. For example, Darwin’s evolutionary theory, the James-Lange theory, the Cannon-Bard theory, Le Doux’s theory, Schachter and Singer’s theory, and Lazarus’ theory. In order to determine to what extent cognitive and biological factors influence emotion, the theories that supports both

After the six hour resting period is over, subjects will wake and take a reaction time test on their smartphones (The application consists of tapping the screen as soon as possible after its color changes. The reaction is recorded in seconds.) three times and record their data.

A reflex arc consists of five essential components – a receptor, sensory neuron, integration center, motor neuron, and an effector. A reflex arc is an automatic response that protects a person from injury by allowing for immediate withdrawal from harmful stimuli. This response is present in situations that call for immediate action, such as when a person steps on a sharp object; instead of sending sensory information to the brain to be processed, a reflex arc rapidly processes and produces the protective response without having to wait for directions from the brain. The process begins when a receptor, which can be specialized cells or the dendrites of a sensory neuron, is activated by the arrival of a stimulus, and ends with the response by an effector.

Doing regular breathing exercise routines will calm your nerves and also practice progressive muscle relaxation (slowly tense and relax each of your muscles in your body) over time.

Its main focus points is manual muscle test and evaluation. Professionals such as doctors, nurses, physical therapists, athletic trainers and personal trainers use this book to search a specific muscle in the body to find a correct test to evaluate a particular muscle. Each chapter offers an expanded treatment and exercise sections to be able to evaluate personal injuries or pains suffered from training. Each chapter goes over a particular section of the body starting out with chapter one being about posture to the last chapter being lower extremities. It explains each muscles purpose, preforming test and proper treatment of each muscle and muscle

Although the accuracy was part of the measurement, the data analyzed only includes reaction time. Therefore, the similar average reaction time between male and female could be due to the difference in accuracy. For example, fast reaction time could have easily been achieved by continuously pressing the same response for every trail. Consequently, the reaction time would be as fast, but the accuracy would be very low. However the finding will not have reflected this important factor. Secondly, because the experiment was conducted online, it is not clear whether the participants actually read and followed the instructions. Prior to the trails, the instructions reminded the participants that “accuracy is more important than speed”. It is possible that the participants missed the instructions and tried to strive for better reaction times rather than accuracy. In addition, the sample size was relatively small compared to the previous experiments which could be another confounding factor.

An analysis of how our body reacts to various social behaviors is needed for the biophysiological perspective regarding interpersonal communication.

There are several types of memory. They include explicit, episodic, semantic, implicit, and procedural memory. Explicit memory is one of the two main divisions of long-term memory. It consists of all information that requires consciously remembered. An example of explicit memory is remembering what was done in class the day before or a sibling being born. Episodic memory is a memory of an autobiographical experience. It is a type of explicit memory. Normally, these memories are emotional and in great detail. A personal episodic memory for me is the Henryville tornado on March 2, 2012 which destroyed my elementary school. This memory for me is episodic because it was very emotional and I can remember almost every detail. Another type of explicit memory is semantic. It includes a person’s memory

According to Martini, F., Tallitsch, R., Nath, J., (2018), the ANS functions outside of our conscious awareness and makes routine adjustments in our body’s systems (Martini, Tallitsch, & Nath, 2018, p. 450). The autonomic nervous system helps maintain the homeostasis of our bodies by regulating body temperature and coordinating cardiovascular, repertory, digestive, excretory, and reproductive functions. Efferent axons innervate the visceral organs and the efferent nerve fibers and ganglia of the ANS organize in two systems or divisions. The sympathetic division and the parasympathetic division. The sympathetic division is most active during times of stress, exertion, or emergency, also known as “flight or fight”. Thus, the sympathetic nervous system increases heart rate, and the forced contractions widen the airways making it easier to breathe. Your body now releases stored energy, which allows for increased strength in muscles, and can also cause your palms to sweat, pupils to dilate, and hair to stand up. The parasympathetic division is most active during resting conditions, hence, why it can also be called, “rest and digest”. This division controls body processes during ordinary situations. It generally slows down your heart rate and decreases your blood

Almost half of a human 's body weight is composed of muscle. There are three distinct types of muscle tissue: cardiac muscle, skeletal muscle, and smooth muscle. Each of the muscle tissues have different structures, properties, characteristics, and roles in our body. Properties of muscle tissues include excitability, contractility, extensibility, and elasticity. Contractility is the ability to shorten, which causes movement of the structures to which the muscles are attached. Excitability is the ability to respond or contract in response to chemical and/or electrical signals. Extensibility is the capacity to stretch to the normal resting length after contracting. Elasticity is the ability to return to the original resting length after a muscle
