Spinal Cord with Nerve Endings

The model illustrates the composition of the spinal cord, magnified to a scale of about 5:1.
The spinal cord is formed by a central channel surrounded by " grey matter" with an outer layer of "white matter". The base features illustrations of various cross-sections through the white and grey matter at the neck, torso, lumbar and sacral regions. Supplied on a base.

IMP 280

Stages of Fertilisation and Development of the Embryo, 2-times magnified

The model illustrates schematically how the ovum matures, how ovulation and fertilistaion occur and how the fertilised ovum develops to the stage where it embeds itself in the uterine wall to begin the growth into an embryo.

The various stages are shown in larger-than-life model form in an ovary, fallopian tube and uterine. An even more enlarged illustration of each is also printed on the base. Supplied on a base. 35x21x20 cm, 1,2 kg

MICRO anatomy Bone Structure

This extremely detailed model depicts a three-dimensional section of a lamellar bone, showing the typical structure of a tubular bone enlarged 80 times. Various planers are shown in cross and longitudinal section through all levels of the bone, as well as a2-plane section through the inner structure of the bone marrow. The typical elements of a lamellar bone are easily identified and help to understand its structure and function with the characteristic osteons , also referred to as Haversian systems. This model allows a graphics illustration of the interplay of the individual components, such as spongy and compact substance, endosteum, cortical substance, osteocytes, Volkmann and Haversian canals. Supplied on base.

IMP 282

MICRO anatomy Liver

This 2-part model shows a highly magnified diagrammatic view of a section of the liver. It illustrates the structure components of the liver in two different enlargements. The left part of the model shows a section of the liver that comprises several liver lobules. The right part of the model is a highly magnified view of the sectioned liver lobule on the left.

Kidney Stone Model

This model is a helpful tool to inform patients about kidney stones (nephrolithiasis) and urinary stones (urolithiasis). It shows an opened right kidney in natural size. The renal calices, the renal pelvis and the ureter are opened as well so that concretions or stones can be identified in the following typical positions :

IMP 284

MICRO anatomy Kidney

This extremely detailed model shows the morphologic/functional units of the kidney greatly magnified. Six model zones illustrate the following fine-tissue structure that serve the production or urine :

IMP 285

MICROanatomy Eye

The model illustrates the microscopc structure of the retina with choroid and sclera. The left block-like, layered side to the model side shows the complete structure of the retina including the supplying vascular layer and parts of the sclera from a light microscopic view. The right part of the model is a sectional enlargement. It shows the microscope structure of the photoreceptors and the cells of the pigmented layer

IMP 286

MICRO anatomy Digestive System

The model illustrations the structure of the fine tissues of four characteristic sections of the digestive system:

The front of the model, from top to bottom, shows a magnified view in histological section of the individual sections of the digestive system and their fine tissue structures. On the back of the model, highly magnified views of didactically interesting areas of each of the digestive system sections shown on the front are emphasized.

IMP287

MICRO anatomy Artery and Vein

The model shows a medium-sized muscular artery with two adjacent veins from the antebrachial area with adjoining fat tissue and muscle enlarged 14 times. The model illustrates the reciprocal anatomical relationship of artery and vein and the basic functional techniques of the venous valves ("valve function" and"muscle pump"). The left vein and the middle artery are fenestrated in the upper anterior segment, revealing the various layers of the wall structure in a cross and longitudinal section and in top view. The right vein is opened throughout in the anterior segment, revealing the orifice of a feeder vein and two venous valves, i.e. "flap valves" formed by a duplication of the tunica intima. On the rear of the model, the relief of two veins is shown to illustrate the functional aspect of the venous valves. Supplied on base.
