CRANIAL NERVE Product Description
The human skull is made up of 22-30 separate bones joined together by sutures. It is almost full size already at birth but the eight bones that subsequently give the skull its stability are not yet fused. A baby\'s skull is "flexible" andcan change shape in order to pass through the narrow birth canal more easily. Asfurther growth occurs, the separate bony elements, configured like the pieces ofa jigsaw puzzle, fuse to form a sturdy casing protecting the brain and delicate sensory organs.
On average an adult female brain weighs around 1245 g and that of an adult male around 1375 g.0 The neocranial system is made up primarily of the two cerebral hemispheres, the cerebellum and midbrain, the thalamus, pons Varolii and the medulla. In our central nervous system (CNS) the cranial and spinal nerves are closely intertwined.
The brain is the most complex organ in the human body. It comprises billions of individual nerve cells and neural pathways. Billions of connections and synapses make it possible for us to think, learn and remember things. Moreover, the brain also controls our emotions, sleep, heart beat and breathing.
