Contraction of cell membrane

Contraction of cell membrane

In this learning activity you'll study the structure of the cell membrane and construct it using the correct molecules.

Muscle Cell Contraction

In this animated activity, learners examine muscle cell contraction and relaxation and consider the role of calcium ions.

The Neuromuscular Junction

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

Eukaryotic Cells: Assembling the Cell

In this interactive object, learners read the definitions of the parts of a cell and assemble a basic eukaryotic cell in a drag and drop exercise. A matching quiz involving cell terms and their definitions completes the activity.

The Cell Membrane and Nanotechnology

In this animated activity, learners examine nanotechnology applications that are based on cell membrane structure and function.

The Cell: Passive Transport Osmosis

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

The Cell: Passive Transport Diffusion

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.

The Cell Cycle

In this animated object, learners examine the different phases of a cell's life.

Antigen Presentation T and B Cell Differentiation.

This learning object demonstrates the process by which antigens are identified, processed, and presented to mediators of the cellular immune system.

Identifying Eukaryotic Animal Cell Organelles

In this animated object, learners are introduced to the structure and function of animal cell organelles.

Red Blood Cells

In this animated and interactive object, learners examine the red blood cell's life cycle and function. A brief exercise completes the activity.

White Blood Cells

In this animated and interactive object, learners examine the structure and functions of granulocytes and agranulocytes. Two exercises complete the activity.

The Summary of the Development of the "H", "A", and "B" Antigens of the ABO System.

In this learning object, students will learn about the attachment process of specific sugars to red cell membranes and how the sugars determine ABO antigenic activity.

Phagocyte Chemotaxis

This animated object illustrates the events leading to the migration of phagocytes into areas of tissue damage and/or bacterial presence. Learners view bacterial cell phagocytosis, its subsequent enzymatic digestion, and exocytosis.

Interpreting Hematology Lab Results

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.

The Organization of the Human Body: Body Cavities

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

Classification of Joints

In this animated object, learners examine the different types of joints and their movements.

Muscle and Connective Tissue

In this colorful and interactive object, learners examine the structure and function of muscle and connective tissues. A quiz completes the activity.
