Study Notes

Terminology and Definitions

  • Caudal: Refers to the direction "toward the tail."
  • Cortex: The outer layer of the cerebrum, composed of gray matter.
  • Neural Groove: Formed within the first three weeks of embryonic development when the neural plate sinks and its edges thicken.
  • Meninges: Three-layer fibrous membranes that surround the brain and spinal cord.
  • Ventricles: Fluid-filled internal chambers located in the brain.
  • Rostral: Indicates the direction "toward the nose; toward the forehead; or higher (vertical)."
  • Blood-Brain Barrier: Comprised of tight junctions between capillary endothelial cells.

Brain Development and Structure

  • Neural Plate: The first embryonic structure to develop during brain development.
  • Myelencephalon: The embryonic structure that develops into the medulla oblongata.
  • Metencephalon: The part of the neural tube that gives rise to the pons.
  • Ventricles Count: There are four ventricles located in the brain.

Brain Anatomy and Functions

  • Superior Colliculi: Structures in the midbrain responsible for mediating visual reflexes.
  • Reticular Formation: Located in the brainstem and spinal cord, it consists of a loose web of gray matter.
  • Cerebrum, Thalamus, and Hypothalamus: Major structures of the forebrain.

Cerebral Hemispheres and Lobes

  • Lobes of the Cerebral Hemispheres: Each hemisphere contains five lobes.
  • Frontal Lobe: Responsible for voluntary motor functions, motivation, memory, mood, and aggression.
  • Parietal Lobe: Extends from the central sulcus to the parieto-occipital sulcus.
  • Occipital Lobe: Contains the primary visual center of the brain.
  • Corpus Callosum: A prominent C-shaped band of nerve tracts connecting the right and left cerebral hemispheres.

Additional Key Facts

  • Thalamus: Often referred to as the "gateway to the cerebral cortex."
  • Commissural Tracts: Most of these tracts are contained within the corpus callosum.
  • Visual Attention: Superior colliculi play a significant role in visual attention and tracking moving objects.
  • Urea: Considered least likely to cross the blood-brain barrier.
  • False Statement: The functions of the parietal lobe do not include voluntary motor functions—those are attributed to the frontal lobe.
