Product Information

Introduce junior and senior high school students to the world of microscopy with inexpensive, unbreakable microslides. Microslides consist of a strip of film with eight photomicrographs, each reproduced exactly as you would see them through a professional microscope under ideal conditions. You can supply all your students with their own microslides. A detailed text folder is included. Viewers are available separately.

When a nerve cell is stimulated, a remarkable series of reactions takes place. In this lesson, students study how a stimulus travels to a muscle cell and how a muscle cell contracts under this stimulus through a group of integrated electro-chemical and physical reactions

1. Single cell (100X)
2. Synapses (200X) - em (300,000X)
3. Axons (400X and 200X)
4. Myelinated axons (600X)
5. Nerve - muscle junction (400X)
6. Synaptic knobs - em (300,000X)
7. Striated muscle cell (1,000X)
8. Sarcomeres - em (45,000X and 31,000X)
