In this animated object, learners trace the olfactory pathway from the nasal cavity to the olfactory cortex.

In this screencast, learners read about the parts of the eye.

In this screencast, learners examine hearing and balance. Detailed drawings of the outer, middle, and inner ear structures are included.

In this animated learning object, learners examine the regulation of inducible operons in bacterial systems.

In this interactive object, the learner views examples of the neutral position of the back and compares that stance to the flat back and swayback positions. A brief quiz completes the activity.

In this screencast, students view a basic wheelchair and identify its parts.

In this interactive object, learners examine the locations of major body cavities and their protective membranes. A drag-and-drop exercise completes the activity.

In this interactive object, the learner reads a case study and then determines appropriate assessment, planning, and intervention strategies necessary during the detoxification phase.

In this animated object, learners examine the major events that occur at the neuromuscular junction.

Learners study two diagrams of the lymphatic system and then test their knowledge in drag-and-drop exercises.

In this lesson on atomic structure, learners examine how the binding energy of electrons affects light production in certain phosphors used in x-rays.

Explore the location, structure, and function of the juxtaglomerular (JG) apparatus.

Using a game show format, learners test their knowledge of various pathologies as organized by body system.

In this screencast, learners identify the parts of the cardiovascular system and examine blood flow.

In this animated object, learners examine synthesis, decomposition, exchange, and reversible reactions.

Learners answer questions about medication from a game board with the headings "Pituitary," "Thyroid," and "Adrenal." Up to three people can play at one time. Contestants "buzz in" their answers to accumulate points.

In this animated object, learners view the "T" and "P" waves and the "QRS complex." A brief quiz completes the activity.

Learners examine the components of the x-ray tubehead, a sealed, heavy metal housing that contains the x-ray tube that produces dental x-rays. This object is designed to help students understand the functions and safety features of the tubehead.

In this animated activity, learners examine the components of the dental x-ray tube and how dental x-rays are generated.

In this animated object, learners examine the major descending tracts of the nervous system. A matching exercise completes the activity.

In this animated object, learners pop balloons to see the medical term for a color or condition.

Explore what passive transport osmosis is and how it moves water through a semipermeable membrane.

In this animated object, learners examine water molecules moving through a semipermeable membrane.

Explore what passive transport diffusion is and how it moves water through a membrane.

In this animated object, learners view molecules as they collide and move between two different solutions. They also observe what happens when the temperature of the solutions is raised or lowered.
