Use this greatly enlarged, vibrantly colored model to study the structure of a typical animal cell. Significant structures within the cell are shown in raised relief, both in full form and in cross section, but cannot be removed from the cell model. These structures include the nucleus, basal membrane, collagen fibers, mitochondria, lysosomes, Golgi apparatus, microvilli, and the smooth and rough endoplasmic reticulum. The full cell model can be removed from the base that depicts adjacent monochromatic animal cells. Size, 21 x 11 x 31 cm.
3B® Scientific. This full-sized replica of the human disarticulated skeleton is perfect for in-depth study of the human skeletal system. The 53-piece product includes a 3-piece skull with cut calvarium and spring-held jaw. Bones of the vertebral column are strung in anatomical order on nylon filament. The bones of 1 hand and 1 foot are loose. The other hand and foot are articulated with wire. The sternum with intracostal cartilage is cast in 1 piece. All other bones are loose. Includes a Human Anatomy Manual. Weight, 4.8 kg.
You have never seen the human eye like this before! Two highly magnified block models depicting human eye microanatomy sit on 1 convenient base. Use the left, layered block model (850x life size) to study the human retina's complete structure, including the supplying vascular layer and parts of the sclera. The right block model (3,800x life size) shows a sectional enlargement of the model on the left and allows in-depth examination of photoreceptor structure. Size, 25 x 23 x 18.5 cm.
