Evoked potential

Membrane Potential in the RMP The membrane potential in the Resting Membrane Potential, or the RMP, is the little bit of voltage or electrical potential going across from the membrane of its regular resting voltage. This is caused because of gradients that make the ions go across the membrane of a cell through ion channels because ions are not soluble so they have to go through channels. These channels are called ion channels that are watery pores allowing ions to get through according to their…

Music is a part of our everyday lives. We listen to music to focus or feel energized when we work, exercise, and go to lively events. In other cases, we use music to relax or clear our minds. In each situation, we are pacing ourselves with the tempo of the songs that we are listening to. Music actually has underlying effects on our bodies that we are not conscious of. When listening to music, the autonomic nervous system and respiratory system are affected. As we receive auditory information…

If muscle membrane potentials vary as a function of ionic composition of the extracellular solution, changes in [K+]o should alter VM values. Moreover, EK, given by the Nernst equation, should accurately predict changing VM values. As extracellular potassium concentration is systematically increased, membrane voltage should be rendered more positive (less negative). Indeed, if [K+]i is 140 mM (according to Bernstein’s model), extracellular [K+] much smaller than 140 mM (e.g., 5.4 mM, 10 mM)…

As with the male counterpart, the ovaries are derived from the genital ridge later descending to their final position in the pelvis. In adults, the ovaries have an ovoid shape and are usually 3-5cm long. They are a layered structure with an outer layer germinal epithelium, tunica albuginea, cortex and medulla that is innermost (fig. 1). Although now challenged by recent discoveries (1), the germinal epithelium; a continuation of the peritoneum, is inaptly named due the mistaken belief that germ…

Hersheypark inside the water park. The roller coaster, is filled with many twists, turns, and loops. This roller coaster is not just any roller coaster, it has a fabulous view of the whole park. The tallest point on this ride, where you feel the highest potential energy, is over 4,586 feet tall. This ride is over four football fields long!! While you are waiting in line you can see that the cars have three rows and in each row there are eight seats. The coaster cars you see as the buckles come…

At the spinal level, the PNS and CNS are bilaterally symmetrical. And studies have shown that the two sides of the spinal cord are not independent due to the findings that unilateral peripheral nociception results in contralateral responses (Koltzeburg, 1999). The contralateral pain was perceived at a lesser magnitude and has a delayed response. This contralateral pain phenomenon can be attributed to a similar pathway as central sensitization leading to secondary hyperalgesia. Primary…

Roller coasters with loop-the-loops are generally rides that appeal to thrill seekers, however without the use of dynamics, these rides would not be able to function. A roller coaster loop-the-loop is a type of large scale centrifuge, as one approaches the loop, the rider's inertial velocity is straight ahead. However the track of the roller coaster keeps the car and therefore the rider, from travelling in a straight path. The force of a rider's acceleration pushes them from…

https://www.youtube.com/watch?v=NcmF5lDL8MM Have you ever been to an amusement park and wondered how a rollercoaster goes around the loop of the track? Well I sure have, this is all due to centripetal force. This is a force that acts on a body moving in a circular path and is directed toward the center around which the body is moving. The curves of these loops on rollercoasters resemble the curves of a circle. The coaster is continuously changing its direction while…

When a baby sees the mom disappears, an electric signal is sent from the eye to the brain’s neurons. The neurons pass the signal down from one another through the different parts of the cells. The neuron sends the signal that the mother has disappeared from the soma down the axon. The axon then sends the impulse out the axon terminals through the synapses, the space between neurons. The impulse gets released as a chemical substance, called a neurotransmitter, through the synapse and the…

Regulatory Behavior Paper The nervous system is in charge of receiving and relaying the information that is collected; it is also in charge of monitoring and responding to both the internal and the external changes that help to control and coordinate the body’s functions. The sensory stimuli is able to become more apparent with the help of a strong and productive nervous system; this would include any change in emotion, memory or the environment. Neurons are known as the messengers of the body.…
