c) How does one nerve cell communicate with another? - Nerve cells communicate with one another through neurotransmitters. 2. a) Explain what neurotransmitters are? - Neurotransmitters are chemical messengers that cross the synaptic gaps between neurons. When released by the sending neuron, neurotransmitters travel across the synapse and bind to receptor sites on the receiving neuron, thereby influencing where that neuron will generate a neural impulse.
Substance P has been implicated in pain syndromes such as low back pain, fibromyalgia, and arthritis. What are the other signs and symptoms? The main fibromyalgia signs and symptoms include deep muscle pain, painful tender points, and morning stiffness. Other major symptoms of fibromyalgia include sleep problems, fatigue, and anxiety. “Common symptoms of fibromyalgia -- also known as fibromyalgia syndrome or FMS -- may include: *
Use: A Hypnotic used for Short-term treatment of insomnia in adults. Side Effects: Drowsiness, dizziness. A bitter or metallic aftertaste, dry mouth. Feeling or being sick.
Normal aggressive behaviour involves an interaction of a system of structures, as opposed to being dependent on separate brain structures. One part of this system is the Amygdala. This is a structure inside the temporal lobe which, plays an important role in the mediation of affective activities and on the expression of mood; mainly fear, rage and aggression. The amygdala is connected to many structures in the brain including the hippocampus, thalamus and pre frontal cortex. It is fundamental for self-preservation as it enables the identification of danger; therefore exhibiting clear links to aggression.
Dreaming is the byproduct of your brain going through your thoughts. You see what your brain is going through at the moment. That is why they seem so random ("Fear-Induced Hallucination: How Sleep Paralysis Triggers Hallucination."). Your body generally goes from NREM sleep to REM sleep about two or three times during the whole sleep cycle. While you're falling asleep, your body slowly starts to shut your muscles down in order to prevent you from rolling around and acting out your dreams.
At the point of delivery the therapist will ask the patient to find a position that they feel comfortable in, this could be seated or lying down. The therapist may ask at this point for the patient to close their eyes and take a deep breath in and out. Then progressing onto the relaxing of the patients muscles. This may start by asking the patient whilst eyes shut and concentrating on their breathing to visit the top of their head feeling the skin on their forehead relaxing and their jaw muscles dropping. By using this technique the therapist will continue down the body expressing to the patient how relaxed they are feeling all the way to the tips of their toes.
If you have lupus you may be extremely tired, have skin rashes or have joint pain. If the disease is more serious, you may have problems with your kidneys, heart, lungs, blood or nervous system. Nearly all people with lupus have a mild to extreme fatigue. Even mild cases of lupus causes an inability to engage in daily activities and exercises. Increased fatigue is a normal sign that a symptom flare about to occur.
It is believed that it expresses how tired we really are. Although that is what majority of us think is the true reason why we yawn, it may not be for some of us. It has been linked to heart disease, number of brain diseases, spinal cord issues, lack of oxygen, and of course fatigue. You often find yourself yawning when you see someone else yawn, or if you're feeling tired. Cooling of the brain is a theories that some researchers have found is the reasoning of yawning.
Tension headaches are the most common type of headache that affects the majority of adults. In this paper I plan on discussing the definition of a tension headache, causes and triggers, muscles involved, treatment and techniques through massage therapy, and at home treatment the client can do for themselves. Tension headaches are usually mild to moderate pain often described as feeling like a tight band around your head. (Mayo, 2011) Also referred to as stress headaches they may appear “episodic” or periodically or “chronic” which is defined as occurring daily. Episodic tension headaches usually begin gradually, and will often occur later in the day.
The human brain can be considered the most complex organ in the human body and also the centrepiece of the nervous system. Although the brain works as a unified whole, neuroscientists can identify areas within it that perform specific functions. Your brain is organized into three interconnected layers: the central core, limbic system and the cerebral cortex, all of which contain structures that regulate everyday life. (The Human Brain, Discovering Psychology) The central core is found in all vertebrates. Its five main regions help regulate basic life processes, including breathing, pulse, arousal, movement, balance and sleep and the early stage of processing sensory information.
