Both endocrine and autonomic functions are explored using diagrams. Mention is made of the direct hypothalamic response to circulating hormones and other substances such as sodium. Th...Hypothalamus; Brain; Dissection
13 Three Critical Vertical Pathways: Neuroanatomy Video Lab - Brain DissectionsSuzanne S. Stensaas, PhDThere 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...Spinothalamic Tract; Dorsal Column-Medical Lemniscus Pathway; Posterior Column; Vertical Pathway; Brain; Dissection
14 The Spinal Cord & Monosynaptic Reflex: Neuroanatomy Video Lab - Brain DissectionsSuzanne S. Stensaas, PhDThe spinal cord's relationship to the foramina, discs and spinal nerves is demonstrated on a model. The dura, ganglia and rootlets are shown as well as the gray and white matter in gross sections at different levels. A model of the cord is used to demonstrate and describe the anatomy of a monosynapt...Spinal Cord; Monosynaptic Reflex; Brain; Dissection
15 Limbic System: Neuroanatomy Video Lab - Brain DissectionsSuzanne S. Stensaas, PhDThe 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...Limbic System; Hippocampus; Brain; Dissection
16 The Most Important Pathway: Motor Control: Neuroanatomy Video Lab - Brain DissectionsSuzanne S. Stensaas, PhDThe origin of the corticospinal tract in the cerebral cortex is traced through gross sections of the hemisphere and brain stem to the spinal cord.
