Neuroanatomy lab introduction

new list of instructions to come Students: This lab will include 2 parts: Half of the time will be spent rotating through prosection stations, and the other half perfoming a pelvic hemisection in preparation for the next lab Those groups in lab 45 (group A) will start by completing the hemi-section. Find your donor table […]

Station 4. Meninges and ventricles

Neuroanatomy lab navigation Meninges See Figure 4.1 and Figure 4.2. Pia mater Arachnoid mater Dura mater Falx cerebri: Separating the cerebral hemispheres Tentorium cerebelli: The tentorium cerebelli separates the cranial cavity into two compartment (Figure 4.1), and there is also a prominent tentorial notch that allows for passage of the brainstem The supratentorial compartment contains […]

Station 5: Blood supply and circulation

Neuroanatomy lab navigation Arterial blood supply Review from FMS 501 Vertebral arteries Supplying the brainstem and cerebellum Anterior and posterior spinal Posterior inferior cerebellar Basilar (unpaired)—multiple pontine branches also come directly off the basilar artery Anterior inferior cerebellar Superior cerebellar Posterior cerebral posterior communicating Internal carotid Supplying the midbrain, thalamus, hypothalamus, and cerebrum Middle cerebral […]

Station 2. Diencephalon

Neuroanatomy lab navigation The diencephalon is composed of the thalamus, hypothalamus, and epithalamus. Thalamus The thalamus is key structure that relays information to the cortex associated with motor and sensory information.  There are also thalamus nuclei that form the connections in the memory and emotion circuit from the hippocampal formation. This portion of the thalamus […]

Station 3: The brainstem

Neuroanatomy lab navigation Parts of the brainstem Midbrain Mesencephalon Pons Metencephalon Medulla Myelencephalon See Figure 1 and Review 2. The basal subdivision of the brainstem is the most anterior and contains mostly the descending fiber tracts. The tegmentum is the location of the cranial nerve nuclei, ascending fiber tracts, and the reticular formation. In the […]
