Principle
Electronystagmography (ENG) is an electrophysiological diagnostic procedure for measuring the movement of the eyes. Several electrodes measure the potential differences that are caused by the eye movements. When looking at a moving, regular, repetiti ...
The heart is a hollow, muscular organ that comprises several secondary muscles. These secondary muscles contract and relax successively, thus pumping the blood through the heart. These muscle activities can be measured electrically as a whole at the ...
With the exception of the heart muscle, the contractions of striated muscles can be controlled at will. This characteristic enables the observation of the activities of individual muscle groups. An electromyogram (EMG) can be used to measure (record) ...
With this experiment, you can find evidence of the electrical activity that is generated during the movement of your eyes. Several electrodes attached to the skin of the face measure all the changes of the electrical voltage that are caused by the mov ...
The cell membrane controls the transport of nutrients and water into the cell as well as the transport of waste products and water out of the cell. This can be passive, i.e. caused by osmotic processes, as well as active. The aim of this experiment is ...
An electrocardiogram (ECG) enables you to observe the regular sequence of heart contractions as well as to determine your heart frequency by determining the interval between two heart contractions. In a second experiment, you will measure the heart f ...
An electrocardiogram (ECG) can record the sum of the electrical activities of all of the heart muscle fibres. Under stress, cardiac activity increases in order to maintain the stability of the cardiovascular system. The heart contraction cannot be con ...
With this experiment, you can determine your own personal reading speed. One's reading speed can be trained and is an important prerequisite for the proper handling of all kinds of texts. You can precisely study the movement of your eyes during the m ...
Principle and tasks
The potential difference between two electrolyte concentrations separated by a membrane (cellophane or cation permeable) is detected by two silver chloride electrodes and measured with a mV meter. The measured and calculated values are compared.
To record an electrocardiogram (ECG) between the left leg and the right and left arm (lead II according to Einthoven). To relate the ECG segments to the course of heart contraction (P wave, P-Q segment, QRS complex, T wave).
Didactical blood pressure measurement system for wireless data transfer of measurement data from test person to computer, thereby permitting flexible and mobile experimental setup.
Tasks
To prepare a plot of blood p ...
