Excitatory postsynaptic potential

devices, an angled ramp is used to bring waves to a height where they can drop into an elevated (relative to sea level) reservoir right behind the plate. The difference in height between sea level and the captured water within the reservoirs creates potential energy that can be harnessed kinetically by draining the water through low head turbines back to sea.…

Introduction: Temperature can affect the rate at which an action potential is generated to excite an action potential within a given skeletal muscle. Maximum contraction is the ability of the muscle to recruit and produce its greatest force during a contraction, and we can observe these effects by using a grip force transducer, which records the functional grip force of the hand. Therefore, the purpose of this lab was to discern how varying temperatures affect maximum contraction. I…

The human body is a unique formation that represents how every component, whether it’s a chemical, cell, or organ all have an important role to have a healthy physiological and anatomical system. Dividing into which part of the body they control most, they create the organ systems that are the nervous, respiratory, articulatory, digestive, endocrine, and the cardiovascular system. The neurological, or the nervous, system is our control system that regulates impulses, chemicals, and commands to…

1. Discuss what a neuron is and the functions of its basic parts (dendrites, soma, axon, myelin sheath). A neuron is a nerve cell. There are about 10,000 specific types of neurons, but there are three most common neurons: sensory, motor, and interneurons. A sensory neuron sends signals to help your brain understand what is going on around you in your environment. Sensory neurons are what make up your senses, (smell, touch, see, taste, and hear.)…

Long Jump Procedures: The participant has to stand behind the line and has to jump off of both feet and attempt to jump as far as possible while landing on both feet. The participant gets three chances to jump as far as they can, then they record their data. Advantages: This test does not take very long to do and it does not require a lot of equipment. Disadvantages: It takes some form to know how to do this properly so some participants may have an advantage over others. Validity: it is a good…

Neurological Factors Affecting Movement Voluntary human movement is regulated and controlled by complex interactions within our central and peripheral nervous systems. The three major types of sensory input come from the visual (eyes), vestibular (inner ear), and somatic (body) sensory systems. The somatic sensory receptors found in muscles, tendons, ligaments, joint capsules, and skin are collectively known as proprioceptors and they gather information about body position and the direction and…

1. The peripheral nervous system, which is divided into the sensory and motor divisions, is involved in physical sensation. Sensory impulses move though the body by being stimulated by a receptor in the skin. It then travels to the sensory neurons and through the afferent fibers, were it will end up at the spinal cord as well as the brain. 2. The motor division of the nervous system are involved in skeletal muscle movement. Motor impulses move through efferent fibers. A motor unit is a motor…

My simple task was to pop a balloon. The item we used to pop the balloon was a mousetrap. I am going to go step by step through how I created my Rube Goldberg machine. First, we started out with a ramp that we dropped the ball on. That was our potential energy. Next, we had a ball drop down a tub at approximately 180°. That was mechanical energy. After that, the ball went through an elbow and hit another ball causing more mechanical energy and thermal energy from a ball hitting the other ball.…

In the first experiment, the acceleration of a falling mini-basketball, the results gathered disagreed with my predicted outcome. Originally, I could not imagine how the graph might appear. I could not visualize an object falling and what its acceleration, position, and velocity might be on the graph. However, after completing the first experiment, I realized that the graphs would look somewhat the same in relation to the basketball since this object was not affected as much as the lighter…

action potentials spontaneously and coordinating contractions during the cardiac cycle. All the cardiac muscle fibers in each region of the heart are electrically linked together. The intercalated disks are connections that electrically join the muscle fibers of the heart into a single unit that can conduct electrical impulses through the entire wall of the heart chamber without stopping. Four structures are embedded in the wall of the heart and responsible for generating the action potentials…
