Brain Flashcards
Largest region of the brain
Cerebrum
Region between cerebrum and the midbrain
Diencephalon
Region containing most neurons
Cerebellum
Region containing midbrain, pons and medulla oblongata
Brainstem
Ridges and grooves of the Brian
Gyri (ridges of brain) and sulci (grooves of brain)
Deep groove that divides the cerebrum into left and right hemispheres
Longitudinal fissures
Bundle of nerves that connects left and right hemispheres
Corpus callosum
Innermost layer that contains blood vessels (Meningeal Layers)
Pia Mater
Middle layer - very thin (Meningeal Layers)
Arachnoid layer
Tough, outer layer (Meningeal Layers)
Dura Mater
Between pia mater and arachnoid mater, contains cerebrospinal fluid (Meningeal Layers)
Subarachnoid space
Bundle of nerve roots that protrude from the end of the spinal cord
Cauda equina
Contains no Myelin, contains motor neurons and interneurons (Grey and white matter)
Grey Matter
Contains Myelin and bundles of axons that carry impulses away from one part of the nerve (Grey and white matter)
White matter
Contains blood vessels, connective tissue and fat (Grey and white matter)
Epidural Space
