Question Answer
Direct control of the pituitary glandDiencephalon
Center for higher function - Memory, learning ,etcCerebrum
Adjusts muscle control based on past movementsCerebellum
Integration center and relay stationBrainstem
Contains the visual areaOccipital lobe
Controls the motor aspects of speechBroca's Area
Contains sensory tracts; gives crude notion of pleasant/unpleasantThalamus
Modifies instructions from primary motor cortexBasal Nuclei
Contains personality centers as well as speech interpretationFrontal lobe
Contains nuclei that control heart rate, blood pressure, and other vital functionsMedulla Oblongata
Coordinates skeletal muscle activityCerebellum
Connects the nervous and endocrine systemsHypothalamus
Center for visual and auditory reflexes Midbrain
Localizes and interprets sensations from the bodySomatic sensory cortex
Dural sinuses are filled withVenous blood
CSF stands forCerebral spinal fluid
CSF is produced inChoroid plexuses
Choroid plexuses are foundIn the ventricles
Deepest meningeal layer is thePia mater
Outer most meningeal layer is theDura mater
Middle meningeal layer is theArachnoid mater
Subarachnoid space holdsCSF
Internal part of spinal cord isGray matter
Inferior to L2, the spinal cord takes the form of theCauda equina
Sensory nerve bodies are on theDorsal root ganglion
What nerves carry both afferent and efferent fibersMixed Nerves
Connective tissue covering an individual nerve fiberEndoneurium
Bundles of nerve fibers wrapped in perineuriumFascicles
Only cranial nerve with effects below the neckVagus
Part of spinal nerve that goes to the back is theDorsal ramus
Axillary, radial, and median nerves are all branches of theBrachial plexus
Largest nerve in the body Sciatic Nerve
Dense collagen layer that is the outside of the nerveEpineurium
12 pairs, emerge from underside of brainCranial nerves
Four cranial nerves carry parasympathetic innervationVagus nerve, facial nerve, glossopharyngeal nerve, oculomotor nerve
Motor fibersVentral root
Spinal nerves form complex interwoven networks calledNerve plexuses
Cervical plexusPhrenic nerve - innervates diaphragm
Brachial plexusxillary nerve, radial nerve, ulnar nerve, median nerve, musculocutaneous nerve
No plexus in thoraxintercostal nerves
Lumbar and sacral plexuses combineFemoral nerve, obturator nerve, S/I gluteal nerves, sciatic nerve
Brain has chambers called ventricles Lateral ventricles, third ventricles, Cerebral aqueduct, fourth ventricle
Lateral ventriclecerebral hemispheres
Third ventriclediencephalon
Cerebral aqueductthrough mid brain
Fourth ventriclepons and medulla
