Ch 14 Flashcards
Sulcus
Wrinkles in the brain
Gryrus
Parts of brain that stick out/lumps/bumps on brain
Cortex(Cerebral)
Grey matter found on the surface of the brain
Cerebrum(Cerebral Cortex)
Grey matter found on the surface of brain
-83% of the brain’s total volume
Cerebellum
Smaller part of the brain that makes up larger portion of neurons found in the brain
Diencephalon
Composed of Thalamus and Hypothalamus
Brain Stem
Midbrain, Pons, Medulla Oblongata
CSF flow
Found in sub arachnoid space of brain
Pia Mater of Brain
Deepest CT/Meningeal layer of brain that sits on Grey Matter/ attached to brain
Arachnoid Mater
Mid CT layer of brain that has Collagen fibers extending to the Pia Mater
Dura Mater
-Fused with Periosteum/ up against periosteum of Cranium
-No epidural space above dura Mater(unlike spinal cord)
-Dense Irregular Tissue filled with Collagen
-Splits to form venous sinuses
Astrocytes
Establishes blood-brain-barrier
Coroid Plexus
Structure composed of Ependymal cells with capillaries Where CSF is created and within brain ventricles and secreted.
Two Lateral Apetures & Median Aperture
Allows CSF to enter sub-arachnoid space and continue circulation
Potential Space
Central Canal
