| Question | Answer |
|---|---|
| Which holds the thalamus/hypothalamus/epithalamus | Diencephalon |
| Which is part of the occipital lobe | Visual area |
| Which makes up the pons/midbrain/medulla | Brain stem |
| Which has to do with reticular information | Diffuse mass of gray matter along brain stem, motor control of visceral organs, RAS (awake/sleep), filter incoming sensory information |
| Which controls balance/equilibrium | Cerebellum |
| Which has motor homunculus/sensory homunculus | Cerebral cortext |
| Which occurs when blood supply to a region is blocked | Stroke |
| What are the 3 connective tissue membranes that protect the brain and spinal cord | Meninges |
| What category do those 3 make up | Dura mater, arachnoid layer/mater, pia mater |
| Cerebrospinal fluid (CSF) is formed from what | Choroid plexuses - capillaries in the ventricles of the brain |
| Which lobe houses the primary somatosensory cortex located | Parietal lobe posterior to central sulcus |
| What is a major function of the pons | Control of breathing |
| What does the longitudinal fissure of the brain do | Separates left and right hemispheres |
| What does the hypothalamus regulate | Nearby pituitary gland |
| What fiber tract connects the 2 brain hemispheres (thus allows for communication) | Corpus collosum |
| Which portion of the diencephalon is a relay station for sensory impulses | Thalamus |
| Which part of the meningeal layer clings to the surface of the brain and spinal cord | Pia mater |
| How many pairs of spinal nerves emerge from the spinal cord | 31 pairs |
| What does the primary motor area allow us to move | Skeletal muscles |
| If you damage the primary motor area of your brain, which lobe is affected | Frontal |
| Someone injures their brain and cannot speak, which specific area of her brain did she injure | Broca's area |
| CSF circulates, know the general area it circulates and where it does not | Circulates in arachnoid space, ventricles, and central canal of the spinal cord |
| What does the reticular activating system play a role in | Awake/sleep cycles and consciousness |
| What controls temperature, endocrine activity, metabolism, and thirst | Hypothalamus |
| The vital centers for the control of visceral activities such as heart rate, breathing, blood pressure, and swallowing, located where | Medulla oblongata |
| What part of the brain controls your balance | Cerebellum |
| What is the correct order from outermost to innermost layers of the meninges | Pia mater, arachnoid layer/mater, dura mater |
| CSF is absorbed into dural venous sinuses via what | Arachnoid granulation |
| What is the blood brain barrier effective against | Excludes many potentially harmful substances from entering the brain, such as wastes |
| In what area of your vertebrae does your spinal cord end | Lumbar |
| What is the cauda equina | A collection of nerves at the inferior end of the spinal cord |
| Describe the dura mater | Outermost leathery layer, double-layered external covering Periosteum: attached to inner surface of the skull Meningeal layer: outer covering of the brain |
| Describe arachnoid layer | Middle layer, weblike extensions span subarachnoid space to attach it to pia mater |
| What is subarachnoid space filled with | Cerebralspinal fluid |
| Describe the pia mater | Internal layer, clings to surface of the brain and spinal cord |
| What is cerebrospinal fluid similar to in composition | Blood plasma |
| What does blood-brain barrier allow through walls | Allows water, glucose, and amino acids to pass through capillary walls Useless as barrier against some substances |
| What may cause death after head blows | Intracranial hemorrhage (bleeding from ruptured vessels) Cerebral edema (swelling of the brain due to inflammatory response to injury) |
| Contusion | Marked nervous tissue destruction occurs, coma may occur |
| Concussion | Slight brain injury, typically little permanent brain damage occurs |
| CVA (Stroke) results in what loss of functions | Hemiplegia: one sided paralysis Aphasia: damage to speech center in left hemisphere |
| TIA (Mini stroke) | Temporary brain ischemia (restriction of blood flow) Numbness, temporary paralysis, impaired speech |
| Gray matter | Surrounds central canal, mostly cell bodies |
| Dorsal (posteria)/Anterior (ventral) horns | D - interneurons (recieve info from sensory neurons) A - motor neurons of somatic (voluntary) nervous system (send info out ventral root) |
| White matter | Three regions: dorsal, lateral, ventral columns Sensory - impulse toward brain Motor - carry impulses from brain to skeletal muscles |
| What are the brain regions | Cerebral hemispheres, diencephalon, brain stem, cerebellum |
| Cerebral hemispheres (cerebrum) | More than half of brain mass, rides (Gyri), grooves (sulci) Fissures (deep grooves) |
| Three main regions of cerebral hemisphere | Cortex, white matter, basal nuclei |
| Cerebral areas involved in special senses | Visual area (occipital) Auditory area (temporal) Olfactory area (temporal) |
| Primary somatic sensory area | Recieves impulses (pain, temp) |
| What connects cerebrum with lower CNS centers | projection fiber tracts |
| What are basal nuclei | Islands of gray matter, regulate voluntary motor activities |
