Normal CNS Critical Anatomy

 

Schematic of the human brain showing connections between the cerebrum and the midbrain.  The relationship between the lateral ventricle, thalamus, and cerebellum are demonstrated.  These are all key fetal sonographic relationships.  Above figure. [1]

 

 

Human brain, frontal (coronal) section.  The divisions of the brain are seen here in a frontal (coronal) slice of the brain:  1. Cerebrum,  2. Thalamus,  3. Mesencephalon – Midbrain,  4. Pons,  5. Medulla oblongata,  6. Medulla spinalis – Spinal cord.  Above figure. [2]

Sagittal section through the brain showing the cerebellum and the corpus callosum.  Above figure. [4]

 

 

Sagittal section through the brain showing greater detail including the 3rd and 4th ventricle and the septum pellucidum.  Above figure. [5]

 

 

Vertebral column demonstrating the 7 cervical vertebra, the 12 thoracic vertebra, and the 5 lumbar vertebra.  Above figure. [6]

The last rib is attached to the 12th thoracic vertebra (T-12), a useful landmark in the fetus.

 

 

This is a transverse view of the spine showing the vertebral body, spinous process, lamina, and articular process.  Above figure. [7]
