The Central Nervous System is the most important organ system in the human body because it is how we control our body. It consists of the spinal cord, nerve cells, and parts of the brain (Organ System Skit). “The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain” (How Does the Nervous System Work? NCBI). In addition, when the body wants to move, the brain sends a message to the…

under the same concept. Most roller coasters start out by ascending to a higher surface which is done to build up enough potential energy to power the carts throughout the entire ride. Energy is usually defined as the ability or capacity to perform work, there are many different types of energy all of which can be grouped into two groups: kinetic energy and potential energy. Potential energy according to "Study.com" is the stored energy that an object has made by positioning, and the idea behind…

The Archers Paradox What is it? Have you ever heard the term “Straight as an arrow”? Well, this isn’t exactly accurate. Arrows don’t exactly fly straight, they twist and bend as they fly. When you draw back and release your bowstring the large force of kinetic energy stored in the limbs gets transferred into the arrow and this force causes the spine of the arrow to start bending as it gets pushed forward. The archer’s paradox is this bending of the arrow around the bow as it is being loosed…

About 8 months ago my husband and my life changed. My husband was diagnosis with a disease called Multiple Sclerosis. I have heard of this disease but I never knew what exactly it is. I didn’t know what the symptoms was, the life expectancy, and it was a very foreign matter for both my husband and I. Since we found out I have done tons of research trying to find out everything I can to get some type of knowledge for this. Overview Multiple Sclerosis or M.S. is a chronic disease. This disease…

the cell. 2. Resting membrane potential is the difference in voltage of the fluids inside a cell and outside a cell. It is measured by the difference in voltage inside and outside of the cell. 3. On the outside of the resting membrane potential it would remain at 0, however on the inside it dropped the voltage from -70 to -40. This happened because with the increase of K+, there was more K+ to pass through the leak channels, resulting in a lower resting membrane potential. There are less leakage…

The refractory period is when the nerve or muscle cell fires during which the cell can’t respond to stimulation not until the resting potential is re-established. This process is called the refractory period. The first part of the refractory period this is called the absolute refractory period. It reaches the start of the action potential until the K+ begins to shut. During this process, the sodium channels are active, so the membrane will not respond to the stimuli. The second part…

The human body is a phenomenal system that is skilled in working with a handful of diverse thought functions. For example, neurons are the building blocks of the nervous system. They interact with one another from the nervous system to transmit messages throughout the body, as well as sensory information. In fact, neurons change from different size and shape. The nervous system contain three separate functioning components: the sensory division, the motor division, and the interneurons. First,…

1. Describe a roller coaster design that the cart was not able to travel through safely. There was only a few things that would make a roller coaster design dangerous for the cart. One example would be how pointy the angle was for of each hill. The more pointy the hills, the more dangerous the landing of the cart would be. Another example would be the height of the loop of the roller coaster. The loop should be high enough so that the cart could travel with more energy. 2. Describe a…

somatosensory and vestibular terminals. Previous studies in guinea pig and rat have shown that cochlear damage results in a decrease of VGLUT1-labeled puncta and an increase in VGLUT2-labeled puncta. This indicates cross-modal compensation that is of potential importance in somatic tinnitus. In order to confirm this hypothesis, knock-out studies in a mouse model of tinnitus…

Cell-Cell Communication in Taste Buds: Activation of Type II cells by taste stimuli causes the release of ATP through pannexin hemichannels and/or CALMH1 channels. The released ATP or sour stimuli can activate Type III cells and causes release of different hormones such as 5-HT and NE via Ca2+-dependent exocytosis. In some instances NE is co-released with 5-HT (Dvoryanchikov et al., 2007; Huang et al., 2008a). The ATP released by Type II taste cells acts as a paracrine as well as an autocrine…
