The Sense of Smell
In this animated object, learners trace the olfactory pathway from the nasal cavity to the olfactory cortex.
The Transfer Function and Frequency Response of a Low Pass Filter
Students learn how to predict how circuits will respond to varying frequency. They solve for the magnitude and phase angles.
Series-Parallel DC Circuits Analysis
Learners follow a methodical approach for the dc analysis of series-parallel circuits.
Voltage Drops in a Series Circuit
Students study the concept that the voltage drop across a series circuit resistor is proportional to its resistance. They then complete a brief quiz.
The Structure of the Muscle Organ
In this animated object, learners examine the various connective tissue layers of the muscle organ. The terms "prime mover," "synergist," "antagonist," "origin," and "insertion" are defined.
Oscilloscope AC Voltage Measurements
In this animated learning object, students view the operation of an oscilloscope that is used to measure AC voltages. A brief quiz completes the activity.

Interpreting Hematology Lab Results
By Kathleen Lee
Learners examine a CBC and study the functions of blood cells, the normal range for each item on the CBC, and possible reasons for increases or decreases from the normal range.
Biomolecules - The Lipids (Video)
By Becky Polk-Pohlman
In this animated object, learners examine neutral fats, phospholipids, and cholesterol. The molecular formula and general function for each are shown.
Physiological Events at the Neural Synapse
In this learning activity you'll review information on the neural synapse.
