3 Three Critical Vertical Pathways: Neuroanatomy Video Lab - Brain DissectionsSuzanne S. Stensaas, PhD, Professor Emeritus, Department of Neurobiology and Anatomy School of Medicine, University of UtahThere is one motor and two sensory pathways that must be mastered. Pain and temperature from the body travel together and vibration and proprioception travel in another pathway each reaching perception in the cortex. Voluntary motor control starts in the cerebral cortex and connects with a motor neu...
4 The Most Important Pathway: Motor Control: Neuroanatomy Video Lab - Brain DissectionsSuzanne S. Stensaas, PhD, Professor Emeritus, Department of Neurobiology and Anatomy School of Medicine, University of UtahThe origin of the corticospinal tract in the cerebral cortex is traced through gross sections of the hemisphere and brain stem to the spinal cord.

6 Olfactory System: Neuroanatomy Video Lab - Brain DissectionsSuzanne S. Stensaas, PhD, Professor Emeritus, Department of Neurobiology and Anatomy School of Medicine, University of UtahBeginning with the location of the sensory cells within the skull the axons are traced into the cranial cavity. Demonstration of the olfactory bulb, olfactory tract and it termination in the forebrain and temporal lobe are indicated. Trauma and meningiomas can produce loss of small (anosmia). Degene...
7 Limbic System: Neuroanatomy Video Lab - Brain DissectionsSuzanne S. Stensaas, PhD, Professor Emeritus, Department of Neurobiology and Anatomy School of Medicine, University of UtahThe decision was made to present a simplified description of a much more complex system using animations to construct a 3D image. Papez circuit is shown on gross specimens with mention of its involvement in memory. The role of the amygdala in fear and the olfactory cortex in temporal lobe epilepsy a...
8 The Visual Pathway: Neuroanatomy Video Lab - Brain DissectionsSuzanne S. Stensaas, PhD, Professor Emeritus, Department of Neurobiology and Anatomy School of Medicine, University of UtahA brief review of the anatomy of the eye and the photic stimulation of the receptors is followed by a gross exploration of the visual pathway from the optic nerve, chiasm, and tract to the thalamus stressing how the left part of the visual world reaches the right hemisphere. Visual fields are relate...
9 The Normal Unfixed Brain: Neuroanatomy Video Lab - Brain DissectionsSuzanne S. Stensaas, PhD, Professor Emeritus, Department of Neurobiology and Anatomy School of Medicine, University of UtahThe consistency and vulnerability of the brain is demonstrated along with the clear and glistening pia and arachnoid and the tough dura. The cushioning function of the CSF is stressed and the features are pointed out on the ventral surface. The uncus and temporal lobes are normal with arteries free ...
10 Orientation: The Planes of the Brain: Neuroanatomy Video Lab - Brain DissectionsSuzanne S. Stensaas, PhD, Professor Emeritus, Department of Neurobiology and Anatomy School of Medicine, University of UtahTerms such as anterior, posterior, inferior and superior are introduced with respect to the hemispheres as well as the brain stem. Terms such as rostral and caudal or dorsal and ventral can mean different things in different areas. Sections in three planes (frontal, axial, and sagittal) are demonstr...
11 The Meninges: Neuroanatomy Video Lab - Brain DissectionsSuzanne S. Stensaas, PhD, Professor Emeritus, Department of Neurobiology and Anatomy School of Medicine, University of UtahThe epidural, subdural and subarachnoid spaces are demonstrated and discussed with respect to trauma and disease. The relationship of the brainstem and cerebellum to the tentorium demonstrates the vulnerability of the brain stem to increased supratentorial pressure and herniation. Arachnoid granulat...
12 Cranial Nerves: Neuroanatomy Video Lab - Brain DissectionsSuzanne S. Stensaas, PhD, Professor Emeritus, Department of Neurobiology and Anatomy School of Medicine, University of UtahThe approach is to learn to associate the cranial nerves with their brainstem level and blood supply. Emphasis is given to the midbrain (3, 4), pons (5, 6, 7, 8), medulla (9, 10, 11, 12) and their most important functions.
13 Sensation from the Body: Neuroanatomy Video Lab - Brain DissectionsSuzanne S. Stensaas, PhD, Professor Emeritus, Department of Neurobiology and Anatomy School of Medicine, University of UtahSensation consists of various modalities, which tend to travel in one of two pathways. The Anterolateral System also known as the Spinothalamic Tract carries pain and temperature. The Dorsal Column-Medical Lemniscus Pathway carries vibration, joint position, and fine 2-point discrimination. Light or...
14 Sensation from the Face: Neuroanatomy Video Lab - Brain DissectionsSuzanne S. Stensaas, PhD, Professor Emeritus, Department of Neurobiology and Anatomy School of Medicine, University of UtahSensation from the face travels in one of two pathways both of which eventually converge to form the trigeminothalamic tract that reaches the thalamus. The tract that carries pain and temperature is confusing because it first descends before crossing while the equivalent of Dorsal Column-Medical Lem...
15 Vestibular System: Neuroanatomy Video Lab - Brain DissectionsSuzanne S. Stensaas, PhD, Professor Emeritus, Department of Neurobiology and Anatomy School of Medicine, University of UtahDiagrams, models and skull preparations are used to describe the vestibular apparatus.
