Neural Tube Structure

In Embryos, The Three Neural Tube sections are: 

  1. The Prosencephalon - Becomes the Forebrain

  2. The Mesencephalon - Becomes the Midbrain

  3. The Rhombencephalon - Becomes the Hindbrain

The Forebrain contains two main units: 

  1. The Telencephalon

  2. The Diencephalon

The Midbrain Contains three main units: 

  1. The Tectum

  2. The Tegmentum 

  3. The Cerebral Aqueduct

The Hindbrain Contains two main units: 

  1. The Metencephalon

  2. The Myelincephalon

The Telencephalon Contains Three subunits: 

  1. Corpus Callosum 

  2. Cerebral Hemispheres

  3. Olfactory Bulbs

The Diencephalon Contains Two Subunits: 

  1. The Thalamus

  2. The Hypothalamus

The Tectum Function: 

  • The “Roof” / Audio Visual Processing

The Tegmentum Function: 

  • Motor Pathways

The Mesencephalon Contains two Subunits: 

  1. The Pons

  2. The Cerebellum 

The Myelencephalon Contains Two Subunits: 

  1. The Medulla Oblongata 

  2. The Medullary Pyramids

The Pons Function: 

  • The Bridge between the Brain and Spinal Cord

The Cerebellum Function: 

  • Coordinates Movement and Balance. 

The Medulla Oblongata structure / Function: 

  • Autonomic Functions + Myelinated Fibers

The Medullary Pyramids Function: 

  • Axon Bundles for Motor Control.
