Module Summaries

In each of these zip files there are two or three documents: Introduction- This should be read before lab each week.

Procedure This is the directions for you to reference out of class if needed.

Questions These are questions from the previous version of the course materials and may or may not be in every lab zip file. Many of the questions are the same; some have been added/removed. These question sections are to help guide your lab write up and make sure you understand the key points.

Full text of Modules 8, 9, 11, and 14 for optional lesson lab session

EMG I (Lab 1):
EMG I investigates the properties of skeletal muscle. The students will record the maximum clench for their dominant hand and then do the same for their non-dominant hand.

EMG II (Lab 2):
EMG II explores the role of skeletal muscle in performing mechanical tasks. The lesson uses a hand dynamometer to demonstrate the use of skeletal muscle when recording the maximum grip strength for both hands.

EEG I (Lab3):
This lesson demonstrates how the brain's electrical activity varies, dependent upon the task being performed. The students will examine different EEG frequency bands (alpha, beta, delta, theta) of the EEG.

EEG II (Lab 4):
Students will record EEG during relaxed and attentive states. The system will display raw EEG, alpha band, and alpha-RMS (integrated alpha) activity so students can determine how state of mind influences the brain's electrical activity in the alpha frequency.

ECG I (Lab 5):
This lesson provides an introduction to the electrocardiograph and recording the heart's electrical signal. The lesson familiarizes the students with a Lead II ECG recording and with the components of the ECG complex.

ECG II (Lab 6):
This lesson explains Einthoven's triangle and allows the students to record their ECG using bipolar Leads (I, II & III). The students will attach Leads I and III and the software will calculate Lead II for them, using Einthoven's law.

ECG and Pulse (Lab 7):
This lesson examines the mechanical action of the heart and peripheral pulse pressure. The lesson uses a pulse plethysmogram transducer and Lead II ECG to demonstrate how the heart pumps blood throughout the body.

Respiratory Cycle I (Lab 8):
This lesson demonstrates the effects of cerebral influence and chemoreceptor influence on the medullary control centers. The students will record chest contraction and expansion using a respiration transducer and correlate the changes with ventilation. A temperature transducer located beneath one nostril will record the ventilation date.

GSR and Polygraph (Lab 9):
This lesson will familiarize students with the standard physiological measures recorded by a polygraph. The lesson looks at the effects of cognitive behavior and emotion. The students will record changes in respiratory rate, heart and skin resistance.

Electrooculogram (EOG) I (Lab 10):
This lesson allows students to record horizontal and vertical eye movement. It demonstrates eye fixation and tracking. Students will perform a number of tasks that will allow them to record the duration of saccades and fixation.

Reaction Time I (Lab 11):
This lesson demonstrates the effect of learning and physiological processes on reaction times. The students will hear two schedules of clicks through a set of  headphones and react by pressing a pushbutton hand switch as quickly as possible.

Pulmonary Function I (Lab 12):
This lesson introduces the students to pulmonary function tests. The students will perform a variety of pulmonary measurements such as: Tidal volume, Inspiratory capacity, Expiratory capacity, Functional residual capacity, Vital capacity and Total lung capacity.

Pulmonary Function II (Lab 13):
Pulmonary Function II builds on the principles established by the previous pulmonary function lesson. The lesson demonstrates how to record and analyze Forced Vital Capacity, Forced Expiratory Volume (FEV 1,2,3) and Maximal Voluntary Ventilation (MVV).

Biofeedback (Lab 14):
This lesson demonstrates the principles of biofeedback training for relaxation purposes. The students will record ECG, heart rate and galvanic skin response. Subjects control the position of a bar graph by influencing their heart rate and GSR.

Aerobic Exercise Physiology (Lab 15):
The Aerobic Exercise Physiology lesson allows the students to record ECG, heart rate, airflow and skin temperature under a variety of conditions. Students will see how their data changes to meet changing metabolic demands.

Systemic Blood Pressure (Lab 16):
The System Blood Pressure lesson allows students to record arterial blood pressure using the auscultatory technique. Student will record blood pressure using a cuff, Korotkoff sounds using a stethoscope, and ECG using Lead II.

Heart Sounds (Lab 17):
Students will listen to heart sounds using a stethoscope placed on the chest over the four heart valves then record heart sounds and ECG Lead II, and correlate mechanical and electrical events of the cardiac cycle.
