Study Notes
Coracobrachialis Muscle Innervation
- The musculocutaneous nerve pierces the coracobrachialis muscle.
- The musculocutaneous nerve is responsible for innervating the coracobrachialis muscle.
- The axillary nerve does not penetrate the coracobrachialis muscle.
pH Meter Functions in Acid-Base Titrations
- The pH meter measures the acidity or alkalinity of a solution during titrations, providing real-time pH readings.
- The voltage generated between the integrated electrodes reflects the hydrogen ion concentration in the solution, which correlates to the pH level.
- A basic rule for recording the titration curve is to plot pH on the y-axis against the volume of titrant on the x-axis.
pH Meter Structure and Components
- The combined glass electrode in a pH meter contains a glass membrane sensitive to hydrogen ions and an internal reference solution.
- The evaluation unit connected to the sensor processes the voltage signal from the electrodes, converting it to a pH value for display.
