Resting potential

Amyotrophic Lateral Sclerosis Neurologist Jean-Martin Charcot in 1869 discovered Amyotrophic Lateral Sclerosis (The ALS Association, 2015). ALS is more commonly referred to as Lou Gehrig’s disease after Lou Gehrig, a great American baseball player whose career unfortunately ended abruptly due to this incurable degenerative disease. ALS is the deterioration of motor neurons in the brain and spinal cord that leads to muscle weakness. This significant decrease in muscle strength eventually…

My phone is sitting next to me on my desk when I hear it begin to ring. I pick it up in my hand and look at the screen to see who is calling me. When I recognize my mother’s caller ID, I tap a button to accept the call. I bring the phone to my ear and hear my mother’s voice through the speaker. We talk for a few minutes, and then eventually we say goodbye. I end the call and place the phone back onto my desk. The body system that enables me to successfully complete this phone call is the…

Fill the flat beaker with water. 6. Place a plastic bag over the top of the cylinder and place it, upside down, in the flat beaker. Make sure the bottom of the beaker is always underwater. 7. Fasten the beaker in place using the stand, clamp and boss. 8. Place one end of the tube inside the large beaker and fasten the other to the cynical flask’s arm. 9. Quickly pour the CaCO3 into the cynical flask, plug in the rubber stopper and start the stop watch. 10. Every 10 seconds,…

Justification and Relevance of Lesson Energy is the ability to do work. It has the potential to make changes, and any changes are due to work being done. This is significant because work can generate energy, and energy itself can do work (i.e., work done on windmills by the wind produces energy, and energy is used in homes to do work). Standards and Learning Objectives Content Learning Standards (s) HS-PS3-2: Energy at the macroscopic scale. • PS3.A: At the macroscopic scale, energy manifests…

Before a Trebuchet is fired, there is a large amount of potential gravitational energy in the counterweight. This is turned into kinetic energy as the counterweight falls. Since the law of the conservation of energy states that the energy has to go somewhere, the energy in the counterweight also needs to go somewhere…

hillock and initial segment where action potentials begin (an area called the “trigger zone”). Sometimes axons have side branches called collaterals, which usually branch off at a 90 ° angle and allow a neuron to communicate with many cells at once. Each axon branch ends in a thin extension series called telodendria, which ends at the synaptic terminals.

experiment was to understand kinetic and potential energy and verify the Law of Conservation of Energy. Kinetic and potential energy are both forms of energy that usually coincide with each other; potential energy usually changes into kinetic energy and vice versa. While potential energy results from an object’s position or arrangement of parts, kinetic energy results from an object’s motion. Together, the sum of an object’s kinetic energy and the potential energy at that instant is its total…

Fish’s consist of a diverse amount of species each known for their characteristics that set them apart from the rest. The characteristics that make the general understanding of a fish are, vertebrate, aquatic, Gills rather than lungs, paired limbs(fins) for locomotion, and are covered with scales. When we see fishes in aquariums we have an irresistible urge to tap the glass, and in doing so, a lot of the fishes get startled and move away performing a sequence of steps called an c-start used as…

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.…

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…
