Gross Neuroanatomy
Learning Objectives:
The successful student will be able to:1- Define the basic terminology and language used in neuroanatomy.2 - Identify key regions and general functions within the cerebral cortex.3 - Identify the major functions of subcortical structures within
the forebrain.4 - Identify the surface structures seen from the ventral aspect of the brainstem.5 - Identify the cerebellum.

Directions in neuroanatomy
Anterior - PosteriorRostral – CaudalDorsal – VentralSuperior – InferiorMedial – Lateral
Note the directional changes below the midbrain
Nervous System:
Central and Peripheral NS (anatomical classification)
CNS = brain and spinal cord (covered by meninges)
PNS = spinal and cranial nerves outside CNS
Automonic and Somatic NS (functional classification)
ANS = innervate smooth muscle and glandsSNS = innervate musculoskeletal & skin sense
organs
Cerebral topography:Four lobes visible from lateral surface – Frontal, Parietal, Occipital, Temporal
Lobes are separated by sulci.Identify the Central sulcus (separates Frontal and Parietal)Identify the Sylvian fissure/sulcus (Lateral sulcus – separates Temporal from Frontal and Parietal)
Cerebral topography:Limbic lobe lies medial and ventral to the Frontal,
Parietal and Temporal lobes
