These important ions help regulate homeostasis in our bodies‚ as well as allowing us to move‚ absorb food‚ heal‚ and reproduce. Understanding how these ions work within our bodies will allow us to comprehend the physiology behind muscle contraction‚ nerve signaling and cell signaling. Upon learning about calcium‚ we already briefly know how

Handout Lab 5 - Cranial Nerves: Assessment of Functions INTRODUCTION The central nervous system (CNS) consists of the brain and the spinal cord. The CNS receives sensory information from other parts of the body or the body’s external environment and transmits motor information to other parts of the body by way of the peripheral nervous system (PNS). The PNS of the human includes 31 pairs of spinal nerves and 12 pairs of cranial nerves. Some nerves contain only motor nerve fibers (efferent fibers);

The nerve impulse The information is transmitted by polarity changes in the membranes of cells due to the presence of neurotransmitters that alter the ionic concentration inside the cell. Moreover‚ inside the neuron proteins and ions are negatively charged . This difference in ion concentration also produces a potential difference between the outer membrane and within the cell . The value reached is about -70 millivolts (negative inside with respect to the value of positive charges outside

The article “The Shaking Women or A History of My Nerves” is an intriguing piece to read as it captures the idea of what it’s like struggling with an unknown disorder. The author‚ Siri Hustvedt‚ provides readers with a vision of her journey through the search of a diagnosis for her mysterious‚ shaking episodes. While on her journey‚ the author provides readers with an insight on various theoretical paradigms‚ historical views of abnormal behaviours and disorders as well as personal experiences living

Lab #3: Initial Velocity of a Projectile | | | Abhishek Samdaria | Pd.4 and 5 | | Lab #3: Initial Velocity of a Projectile Theory: How can we determine the initial velocity of a projectile? Experimental Design: The purpose behind this experiment was to determine the initial velocity of a projectile. Projection motion consists of kinematics of motion in the x and y directions. With two dimension kinematics‚ there are the x and y components in any given velocity. In projectile

at a velocity of 80 km/h when he sees an old woman crossing the road 45 m away. He immediately steps hard on the brakes to get the maximum acceleration of 7.5 m/square second. how far will he go before stopping? Will he hit the old woman? 3. the time a male bungee jumper if freely falling is 1.5 seconds (a) What is the velocity of the jumper at the end of 1.5 s? (b) how high did he fall? 4.

Introduction: This lab is an experiment in terminal velocity‚ the speed an object cannot surpass due to frictional forces. To begin‚ it is important to note that the objects in this lab are not in a free-fall scenario. A free-fall scenario is a situation where an object is dropped in a frictionless environment‚ and the only force that is acting upon it is the force of gravity. In a free fall environment‚ terminal velocity would not occur‚ because no frictional forces would act on the object to
