metencephalon and myelencephalon
list the structures of the adult brain that develop from secondary brain vesicles
telencephalon, diencephalon, metencephalon, myelencephalon
structures in the telencephalon
cerebral hemispheres
structures in the diencephalon
thalamus, hypothalamus, and epithalamus
structures in the metencephalon
bons and cerebellum
structures in the myelencephalon
medulla oblongata
what structures are included in the brain stem
midbrain, pons, and medulla oblongata
brain classified into four regions
brain stem (midbrain, pons, and medulla), cerebellum, diencephalon, cerebral hemispheres
cortex
outer layer of gray matter, formed from neuronal cell bodies, located in cerebrum and cerebellum
what types of cells line the ventricles of the brain
ependymal cells
location of lateral ventricles
located in cerebral hemispheres
location of third ventricle
lies in diencephalon
what structure connects the third ventricle with the lateral ventricles
interventricular foramen
cerebral aqueduct
connects 3rd and 4th ventricles
location of fourth ventricle
lies in hindbrain, connects to central canal of the spinal cord
