Document Summary
If you want to manipulate a 3d model of the brain online, you can go to www. brainfacts. org. Nervous system in charge of mediating a large range of sensations: Giving us information about our external environment. Knowing where the parts of your body are relative to one another in space. This is the characteristic which allows you to clap your hands with your eyes closed. Specialized receptors in our muscles and joints: pain. Letting us know when something is about to damage our bodies, has damaged our bodies, or is not allowing us to heal. Pain is covered in the next lecture with dr. jeff mogil. The activity of afferent nerve fibres generates somatic sensations: nerves are bundles of axons. The cell bodies are found in the dorsal root ganglia (for the nerves innervating the body) and in the trigeminal ganglia (for the nerves innervating the head)
