Our body is a store of wonders. Amazing organs, incredible skeleton, awe-inspiring functions and inter-relations among them form the complex machine called human body. The study of anatomy describes the structures and relationships between the body parts which may vary for different people only in shape, size and color.
No more dependence on Cadavers
Although dissection of human cadaver used to be the only way to investigate anatomy in the early days, it is the high quality anatomical models now, which have reduced the need for the anatomical specimens and the cadaver for the purpose of anatomical education.
Owning and preserving a cadaver or the anatomical specimens involves spending large amount of money and chances of facing ethical and legal issues. And after obtaining them there come the risks of damage, theft or simply getting destroyed or decomposed over time and usages. Instead, use of high quality and exactly alike( cast from the original) anatomical models serve the same purposes but without the hassles.
Anatomical models are the better alternatives.
Today the anatomical models have become essential tool to study and explain internal and external structure of the human body and also the functions of various systems. On part of the students there is no need to struggle, enduring the strong smell of medicines in the laboratory, for a chance to look at the body part under study. Now it is the same organ, artificial but hard to differentiate from the original, is available for study anytime. There is no hassle with respect to preservation; one can buy them for personal use as well.
The use of anatomical models in the anatomical education has been proved to be a big success in the teaching and learning. Models help to focus on specific characteristics of an anatomical structure that are important in the educational objectives of the curriculum. For medical and dental students and professionals accurate models are helpful in guiding cadaver dissection by providing clear idea and knowledge about approach to a structure or region.
The application of analytical models in a medical curriculum enables and enhances students’ learning. The model is either presented as a standalone learning object or it can be a part of the larger group of parts representing a functional area of the body.
While the models of different organs lead to specialized medical training include heart organ models, skin and dermatology models, immunity and cancer models, ear-nose- throat models, etc., the function based human organ models include respiratory models, urinary models, vascular system models and digestive models. The skeletal anatomy models representing the various joints and associated bones and cartilage caters to bone specialists while the eye models showing the various parts of our visual system including the cornia, pupil, lens, retina, etc. in the identical look as the original used extensively by optometrists. Also to help instruct patients and students on physical fitness, there is a range of diet and exercise models.
3D models help in better visualization
Spatial visualization is very important in the study of human parts, for students need to know not only the structures and functions but also the spatial relationships to surrounding structures. While books and charts provide two-dimensional illustrations, a three dimensional model helps to perceive the relative position of a part with respect to the changed position of a connected part.
Students can rotate and manipulate the structures from various views. This visual-spatial ability helps students to mentally manipulate objectives in three dimensions. Such ability is important for medical students to understand anatomical structures and is also important to surgical trainees and surgeons.
The anatomical models play the crucial role in acquiring the special skills for the medical and dental students in terms of correctly visualizing and mentally manipulating the parts inside the human body when the anatomy is presented in various planes and positions.
