cerebrum, cerebellum, brain stem – brainstem consists of the medulla, pons, and midbrain. (may include part of the diencephalon or cerebellum) • cerebral cortex, sulci, gyri - sulci and gyri are the bumps and grooves due to the folding. The folding of the outer layer is called the cerebral cortex. In humans is a sheet of tissue about 3mm thick and varying at different regions at the brain. About 2.5 sqft if laid out. • corpus callosum – collection of 2.5 million nerve fibers connecting the right and left cerebral hemispheres. cerebral lobes : occipital, parietal, temporal, frontal • Andreas Vesalius – most beautiful drawings of human anatomy in 543 De humani corporis fabrica. meninges: dura, arachnoid, pia – dura mater a layer of skin covering the brain that can be peeled away. Reveals another much more delicate layer called the arachnoid. Pia mater is underneath the arachnoid layer; between these two is the subarachboid space. Collectively called the meninges. • meningitis - if the mininges gets inflamed as a result od infection or other processes, this is called meningitis and is extremely dangerous due to its close proximity to the brain. cerebrospinal fluid (CSF) – in the subarachnoid layer is the csf, cushions the brain inside the skull and transports soluble substances through the central nervous system. • René Descartes – treatise on man or la home de rene Descartes: contains drawings of man touching fire in question of human behavior and the mind body issue when touching the fire and it leading us to pull away as well as detailed drawings of the eye in question of perception and how we view the world.

• Luigi Galvani – studied the effects of electrical stimulation on animal muscles. • Camilio Golgi, Golgi stain – created the golgi stain allowed for us to see the nerve cells. Created in his spare time, he called it la reazione near – the black reaction. It made neurons together with their dendrites and axons, eminently visible under the microscope. It contain potassium dichromate and silver nitrate. The elaborate interconnectivity of nerve cells in the brain was illustrated by these two. Santiago Ramón y Cajal – spent thousands of hours looking at the golgi stained nerve cells and drew detailed drawing s of the neurons from the cerebral cortex. Chapter 3: Chemistry and Life • chemistry, alchemy – chemistry is derived from older word and discipline, alchemy. Chemistry is the scientific endeavor concerned with the nature of matter and its transformations. Periodic table – of the chemical elements qualifies as one of he great achievements of the human intellect, representing a large amount of information in a very compact form. • Dmitri Mendeleev – Russian chemist put forth a way of organizing the known chemical elements into what we now call the periodic table. He predicted the existence of several not yet discovered chemical elements.
