(37 cards)
Dura mater
Tough outer layer of the meninges
Arachnoid mater
Delicate weblike middle layer of the meninges
Pia mater
Inner layer of meninges that encloses brain and spinal chord
Cerebrospinal fluid
Fluid in ventricles of brain, the subarachnoid space of the meninges, and central canal of spinal cord
Choroid plexus
Mass of specialized capillaries that secretes cerebrospinal fluid into ventricle of the brain
Ventricles
Cavities such as brain ventricles filled with cerebrospinal fluid or heart ventricles that contain blood
Cerebrum
Part of brain in upper part of cranial cavity that provides higher mental functions
Cerebral hemisphere
One of the large paired structures that constitute the cerebrum
Cerebellum
Part of brain that coordinates skeletal muscle movement
Brain stem
Portion of brain that includes midbrain, pons, medulla oblongata
Corpus callosum
Mass of white matter in brain composes of nerve fibers connecting right and left cerebral hemispheres
Gyrus
Elevation on brains surface caused by infolding
Sulcus
Shallow groove such as between convolutions on surface of brain
Cerebral cortex
outer layer of cerebrum
Broca’s area
Region of frontal love that coordinates complex muscular actions of mouth, tongue, larynx, making speech possible
Hippocampus
Part of cerebral cortex where memories form
Basal nuclei
Mass of gray matter deep within cerebral hemisphere of brain
Diencephalon
Part of brain in religion of third ventricle that includes thalamus and hypothalamus
Thalamus
Mass of gray matter at base of cerebrum in wall of third ventricle
Hypothalamus
Part of brain located below the thalamus and forming floor of third ventricle
Limbic system
Connected structures in brain that produce emotional feelings
Reticular formation
Complex network of nerve fibers in brainstem that arouses the cerebrum
Midbrain
Small religion of brainstem between diencephalon and the pons
Pons
Part of brainstem above medulla oblongata and below midbrain
