Module Summaries
Full text of Modules 8, 9, 11, and 14 for
optional lesson lab session
EMG I:
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:
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:
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:
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:
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:
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:
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:
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:
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:
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:
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:
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:
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:
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:
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:
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:
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.
