Muscle

Biopac Science Lab comes with two lessons focused on muscle activity:

Lesson 1 — EMG I Electromyography: Motor Unit Recruitment
- Lesson 1 investigates the properties of skeletal muscle. Students record the EMG data associated with the maximum clench strength for their dominant hand and non-dominant hand. The system records and displays both the raw and integrated EMG signals. Students compare clench strength between their two arms and listen to the sound of their EMG. It is also possible for students to perform a cross-group analysis.
Lesson 2 — EMG II Electromyography: Mechanical Work
- Lesson 2 examines motor unit recruitment and skeletal muscle fatigue. Students lift hand weights to demonstrate the use of skeletal muscle and record EMG while inducing muscle fatigue. Students see the level of motor unit recruitment associated with the amount of applied force.

Name	Description	Cart
General-purpose Electrodes	These pre-gelled disposable electrodes have a circular contact and are most suitable for short-term recordings, including surface EMG, ECG, EOG, etc. The small vinyl backing allows close electrode placement where necessary, and a slightly less firm adhesive allows "ouchless" removal. The electrodes incorporate liquid electrolyte gel and moderately-high chloride salt concentration for quick, accurate readings.…	$45.00 - $340.00Select options

Headphones – Monaural	These monaural headphones are used with Biopac Science Lab MP40 and Biopac Student Lab MP45* for stimulus response experiments and to listen to EMG signals. The 40HP is a wide-response, high-efficiency headphone. * BSL 4.0.2 and above includes a headphone output option for monitoring stethoscope sounds through OUT1/OUT1A/40HP via the MP Analog Output or headphone jack.	$30.00Add to cart
