QuestionAnswer
1.) different parts of the brain and what they do: Brainstem: Control Blood Pressure and Ventilation
Thalamus: Sensory Relay, to Cerebrum
Hypothalamus: Control Hunger, Thirst and Body Temperature.
Pineal Gland: Melatonin and sleep patterns
Cerebellum: Coordination
Cerebrum: Consciousness, Comprehension, Purposeful and movement
2.)know the connection between the two sides of the brain.- the two hemispheres Corpus Callosum
3.) What are the fissures- the central sulcus, what's on what side and what is on the other and what it separates. or the longitudinal
Fissure/Central Sulcus: Separates the parietal Lobe from the Frontal Lobe
Fissure/Lateral: Run roughly horizontally on the lateral surface of the cerebral hemispheres, one on each side.
Fissure/Transverse: Separates cerebrum from cerebellum.
Fissure/Longitudinal divides the cerebrum into right and left cerebral hemispheres.
4.) know the ventricles: which ones are in the hemispheres? Lateral-The ventricles of the brain are a communicating network of cavities filled with cerebrospinal fluid (CSF) and located within the brain parenchyma.
The ventricular system is composed of 2 lateral ventricles, the third ventricle, the cerebral aqueduct, and the fourth ventricle (see the images below).
The choroid plexuses are located in the ventricles produce CSF, which fills the ventricles and subarachnoid space, following a cycle of constant production and reabsorption.
5.) What is the Falx Cerebri? Sheet of Dura
6.) if you see a cross sections of the brain like he has in the book: you would have to know where the cortex is the vassal ganglia, the thalamus, and the hypothalamus, and corpus callosum
7) know the function of the csf: the vessels carrying the blood up to the brain, and the vessels bringing it down. Vessel Carrying the blood up to the Brain and the vessel bringing it down. Normal volume of CSF in the brain is 150ML. Most CSF is found in the Subarachnoid space
8) what happens if your brain is deprived of blood for a few seconds? you lose consciousness-4-6 minutes it starts to die.
9) know what the blood brain barrier lets through and what it does not NO(Insulin, Protein, Stains) YES(Glucose)
