Functions of CNSIII. CSFIV. Clinical correlatesV. Cerebrum VI. Diencephalon VII. Cerebellum Current Lecture-functions of CNS-processes incoming information from PNS via sensory neurons-initiates response if needed via motor neurons-cerebrospinal fluid (CSF)-produced in the 4 ventricles of the brain by the choroid plexus -reabsorbed into the bloodstream by dural venous circulation in the cranial cavity through a structure called arachnoid villus-clinical correlates-hydrocephalus: increase in CSF production and lack of proper drainage leads to accumulation of extra CSF volume-treatment: shunt-meningitis: inflammation of meninges in brain or spinal cordThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.-bacterial is more serious than viral-physicians test: touch your chin to your chest, if neck flexion is stiff order a CSF analysis-cerebrum-outer layer of grey matter called the cerebral cortex-inner core of white matter-surface is highly convoluted consisting of raised regions called gyri and separated by grooves called sulci-lobes1. frontal: higher intellectual function, personality, voluntary motor control of skeletal muscle2. parietal: sensory, understanding speech and expressing thoughts and emotions3. temporal: primary auditory cortex, interpretation of olfactory sensations4. occipital: primary visual cortex-lateral ventricles filled with CSF: hollow cavities within cerebrum-diencephalon: located in the central core of the brain; connects the cerebrum to the brainstem-thalamus: right and left cerebellar lobes separated by third ventricle-hypothalamus: master control of ANS-primary link between the nervous system and the endocrine system; physically connected to the pituitary gland-regulates: hunger, thirst, body temperature, sleep-wake cycles, rage, sexual desire-cerebellum-2 lobes connected by the vermus-located posteriorly, inferior to the occipital lobe and posterior to the pons and medulla oblongata and 4th ventricle-responsible for coordination of skeletal muscle contractions-damage or disease produces ataxia (inability to coordinate voluntary motor
