![]() Provide the name and # of the cranial nerves involved in each of the following activities, sensations, or disorders. From this space it drains through the *arachnoid villi* into the *dural sinuses*. *MENINX* *DESCRIPTION* dura mater outermost meninx covering the brain composed of tough fibrous connective tissue pia mater innermost meninx covering the brain delivate and highly vascular arachnoid villi structures instrumental in returning cerebrospinal fluid to the venous blood in the dural venous sinuses choroid plexus structure that produces the cerebrospinal fluid arachnoid mater middle meninx like a cobweb in structure dura mater its outer layer forms the periosteum of the skull falx cerebri a dural fold that attaches the cerebrum to the crista galli of the skull tentorium cerebelli a dural fold separating the cerebrum from the cerebellum Cerebral spinal fluid flows from the fourth ventricle into the *subarachnoid space* surround the brain and spinal cord. brainstem controls autonomic functions Identify the meningeal (or associated) structures described below. Where in the brain are the centers for these reflexes located? midbrain Explain how this phenomenon relates to the unaffected parts of their brain involved in sensory input. returns after coma, but cortical function does not Patients in a vegetative state will often reflexively respond to visual and auditory stimuli. state occurs because function of brain stem & dien. base contains more centers vital to life (breathing, heart rate, etc.) Explain how patients in a vegetative state can have no damage to their cerebral cortex and yet lack awareness of their environment. fibers cross to the opposite side of the body thru the medulla Explain why trauma to the brain stem is often much more dangerous than trauma to the frontal lobes. Explain why the left side (rather than the right side) is affected. and basal nuclei, giving them their stripes (and therefore, its name) A brain hemorrhage within the region of the right internal capsule results in paralysis of the left side of the body. forebrain the diencephalon, including the thalamus, optic chiasma, and hypothalamus hindbrain the medulla oblongata, pons, and cerebellum forebrain the cerebral hemispheres What is the function of the basal nuclei? control voluntary movement What is the striatum, and how is it related to the fibers of the internal capsule? fibers of internal capsule pass thru dien. *STRUCTURE* *DESCRIPTION* hypothalamus site of regulation of body temperature and water balance most important autonomic center optic chiasma site where medial fibers of the option nerves cross corpora quadrigemina located in the midbrain contains reflex centers for vision and audition cerebellum responsible for regulation of posture and coordination of complex muscular movements thalamus important synapse site for afferent fibers traveling to the sensory cortex medulla oblongata contains autonomic centers regulating blood pressure, heart rate, and respiratory rhythm, as well as coughing, sneezing, and swallowing centers corpus callosum large commissure connecting the cerebral hemispheres fornix fiber tract involved with olfaction cerebral aqueduct connects the third and fourth ventricle thalamus encloses the third ventricle Designate the embryonic origin of each group as the hindbrain, midbrain, or forebrain. Using the letters in front of terms from question 5, match the appropriate structures with the descriptions given below. The caudate nucleus, putamen, and globus pallidus are collectively called the *basal nuclei*. A fiber tract that provides for communication between different parts of the same cerebral hemisphere is call a(n) *association* tract, whereas one that carries impulses from the cerebrum to lower CNS areas is called a(n) *projection* tract. TIA.Gray matter is composed of *neuron cell bodies*. As you can tell, I’m not a programmer, though I was 30 years ago. ![]() I’m not sure if this is what is needed, but as you might have guessed it didn’t make a difference. I don’t know if it matters, but I’m on MacOS Catalina. ImportError: No module named html2markdownĬan you help me work through this? Thanks, and no worries if I’m asking too much. I’ve set up GitHub Desktop, installed CodeRunner, and downloaded your file, and updated the file paths. I could use some help getting started with your python script. ![]() In Obsidian, my notes get center stage while I can still use the graph view for thinking about connections. TheBrain’s Plex feels like it’s focal point, rather than my content. ![]() Obsidian flipped me by creating such a frictionless way to stay in my content. I’ve also been a TheBrain User since around 2008 (I think).
