Brain model in eight parts
Denna åttadelade hjärnmodell visar hjärnstammen i två delar, lillhjärnan i 2 delar, 2 delar med samlad frontal, parietal lob och två delar med temporallob. Visning av strukturer som corpus callosum, hippocampus, kranialnerver är tydligt …
Compared to the other brain models in our range, this model has the most naturally occurring surface, which is both relatively shiny and has small thin blood vessels in the grooves between the brain's windings. It can be separated into eight parts and therefore one can easily see the inner structures of the brain. The model is a cheap alternative to our brain models in higher price ranges.
The model is molded in sturdy hard plastic. Unlike many of our other brain models that are molded in flexible, hollow plastic, this model's material can neither be compressed nor changed. Some people probably think that it is not so comfortable to touch and work with, others think it is of no importance.
The eight parts are held together by small, discreet magnets. The different areas of the brain each have a color tone and below you can read about the anatomical details such as. the limbic system. The model is a bit smaller than the brain of an adult. The dimensions are 11 x 12 x 15 cm. It weighs 700 grams and comes on a white removable bar, which is also very sturdy.
Important anatomical structures are numbered on the model. An overview with naming is included in the purchase, compare the mentioned numbers. Naming only in English
NB The numbering and naming are indicative. Therefore, be critical, since speech at one anatomical structure may be located on the border of another structure
Anatomically, the model shows the human brain which can be divided into the cerebrum, cerebellum and trunk (truncus encephali).
These three structures are clearly separated by different color tones and the difference between gray and white substance is clearly seen in this model.
In the big brain (telencephalon and diencephalon) you see first and foremost the brain lobes and the thalamus and hypothalamus (and the pituitary gland).
In the cerebellum you can see the vermis cerebelli and the cerebellar hemispheres (hemisperium cerebelli).
In the brain stem you see the three parts (the central brain, the brain bridge and the extended marrow) and the roots of the cranial nerves (also called the brain nerves).
Other structures such as e.g. the brain vault, fornix, some of the ventricular system and the first two cranial nerves (the olfactory and optic nerve), which do not originate from the brain stem.
The pictures on the left show how the model can be separated into eight parts. In this way the internal structures of the brain can be studied. Several of the structures are seen in three dimensions.
The numbering is seen on the left side of the model, the cranial nerves are clear in a strong yellow color and in general you can see the small thin blood vessels both on the model's surface and on some of the internal structures.
The limbic system
Many of our customers ask about the limbic system when buying models of the brain. Therefore, this description.
The limbic system encompasses various anatomical structures in the central nervous system (CNS), and is primarily responsible for emotional functions such as anxiety, aggressiveness, mood, memory, and social adaptability. Clinically, therefore, it is often related to psychiatric disorders.
The limbic system includes amygdala, hippocampus, gyrus parahippocampalis, hypothalamus, fornix, corpus mammillar, prefrontal cortex and brainstem monoaminergic system. The list is a bit longer - especially since numerous fiber connections link the limbic structures. Many customers especially demand amygdala and hippocampus (that's why they are mentioned first in this section).
NB: In this model you see the hippocampus and some of the other limbic structures such as. fornix - but not amygdala.
Amygdala i is involved in anxiety and emotional staining of mental impressions. It lies as an almond-shaped nucleus IN FRONT of the hippocampus in the foremost part of the temporal lobe (the amygdala and hippocampus are therefore separated.)
The hippocampus is involved in memory. It lies as an irregular twisted structure in the medial part of the temporal lobe.
Since the amygdala is FRONT of the hippocampus (hence further forward "toward the forehead"), both of these structures can only be seen on a brain model, if the model comprises at least two frontal incisions through the temporal lobe - or if the brain model is partially translucent (the frontal section corresponds somewhat to one incision "from ear to ear").
We have not yet seen a model of the brain showing two sections through the temporal lobe - so that both the amygdala and the hippocampus are seen. In our assortment, on the other hand, we have a partially transparent model of the brain that shows both structures - in the highest price range. See the model here: LINK
All our models of the brain can be separated into different parts. All models (both with and without educational colors) which can be divided into four or more parts, show the hippocampus. In addition, on almost all of these models, the hippocampus is numbered and named on an overview that can be downloaded from the product descriptions of the brain models. This also applies to this brain model.
