Exercise 1: The effects of nerve stimulation A. Describe briefly what you have done for this section (maximum 100 words). Basically I am the volunteer. Two students handle the system while one student helps to spread the adequate electrode cream on the volunteer’s left wrist. The system is set to continuous‚ frequency is 1Hz‚ pulse duration at 200μs and pulse current at 10mA. The stimulator is switched off to disconnect the isolated stimulator terminals. The stimulus is then switched on and

Anatomy & Physiology I Cranial Nerve Lab Report: Zoe’s Case Annastelle L. Cohen‚ Brandi Brown‚ Mariann Killen Howard Community College BIOL-203: Anatomy & Physiology I Professor Canham April 26‚ 2016 Introduction There are twelve pairs of cranial nerves associated with the human brain that all have individual and essential functions. They are represented by a name that is followed by a Roman numeral. The cranial nerves are organized in a cranial to caudal sequence (Howard Community

Cnidarians have radially symmetrical bodies organized around a gastrovascular cavity. In hydras‚ neurons controlling the contraction and expansion of the gastrovascular cavity are arranged in diffuse nerve nets. The nervous systems of more complex animals contain nerve nets‚ as well as nerves‚ which are bundles of fiber like extensions of neurons. With cephalization come more nervous systems that are complex. Neurons are clustered

There are three main nerves in your hand radial nerve‚ median nerve‚ and ulnar nerve. Each one of these gives movement and feeling to different areas of the hand. The ulnar nerve is one of the three main nerves in your arm. It travels from your neck down into your hand. The most common place for this nerve is behind the inside part of the elbow. The radial nerve descends down the arm with in the triceps with in the upper arm. Then moves down the arm within the humerus also known as the radial

Sara Otto Intro to Literature (MTWR‚ 8AM) In Class Writing Assignment on “A & P” July 8‚ 2013 Professor Sullivan Word Count: 916 Impulse The short story “A & P” by John Updike is a corky and humorous read. The casual‚ self-venting‚ adolescent depiction of an absurd event that unfolded in a small town grocery store is a peculiar and yet entertaining read for all audiences. The theme of this story has to do with adolescent stressors‚ choices and consequences‚ and standing up for what one

experiment is to examine the results of stimulation on a frog’s sciatic nerve by looking at its compound action potential‚ the conduction velocity‚ and by quantifying the total and absolute refractory period between the nerve at room and cold temperature. An oscilloscope‚ preamplifier‚ and stimulator were used to stimulate the frog’s nerve located in the nerve chamber. Threshold voltage was determined by stimulating the nerve at increasing voltages until a compound action potential resulted. Absolute

carrier impulses from the CNS to the periphery‚ the peripheral nerves in turn have the funsion to carry messages from one part of the organism to another‚ so we can understand the action of these drugs. They act in the prevention‚ generation and propagation of the nervous impulse. Acting on the blocking of the depolarization initiation‚ allowing Na + to enter the nerve cell from rest to the trigger threshold (- 50a - 60 mV) would consequently impede the initiation and propagation of the impulse. Therefore

Homeostasis and Exercise Lab Living Environment/Lab #7 Ms. Iadanza December 2012 Problem: How does exercise affect a person’s heart rate‚ breathing rate‚ and perspiration level? Background Information: Homeostasis is the maintaining of a balanced condition in the body despite changing external conditions or demands on the body. The circulatory system works with the respiratory system in order to deliver nutrients to the body’s cells. The respiratory system is made of the mouth and

reliability. This will ensure that all data collected and measured in the lab are accurate and reliable as well. The process of testing an instrument’s accuracy is known as calibration. The purpose of this lab was to calibrate a variety of equipment frequently utilized in the Exercise Physiology lab and to become familiar with the operation of the calibrated equipment (Lab manual). The equipment calibrated in the exercise physiology lab was the speed of the Parvo treadmill‚ the incline of the Cosmed treadmill
