401 Hypothalamus: Neuroanatomy Video Lab - Brain DissectionsSuzanne S. Stensaas, PhDGross specimens are used to demonstrate the area of the hypothalamus and its relationship to surrounding structures. 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
402 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
403 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
404 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
405 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. Using an animation, the terms upper and lower motor neuron are defined and clinical signs and symptom listed.Corticospinal Tract; Cerebral Cortex; Motor Neuron; Brain; Dissection
406 The Unfixed Spinal Cord: 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...Unfixed Spinal Cord; Spinal Cord; Brain; Dissection
407 Olfactory System: Neuroanatomy Video Lab - Brain DissectionsSuzanne S. Stensaas, PhDBeginning 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...Olfactory System; Olfactory Bulb; Anosmia; Brain; Dissection
408 The Meninges: Neuroanatomy Video Lab - Brain DissectionsSuzanne S. Stensaas, PhDThe 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...Meninges; Brain; Dissection
409 Orientation: The Planes of the Brain: Neuroanatomy Video Lab - Brain DissectionsSuzanne S. Stensaas, PhDTerms 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...Frontal; Axial; Sagittal; Brain; Dissection
410 The Visual Pathway: Neuroanatomy Video Lab - Brain DissectionsSuzanne S. Stensaas, PhDA 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...Visual Pathway; Brain; Dissections
411 The Normal Unfixed Brain: Neuroanatomy Video Lab - Brain DissectionsSuzanne S. Stensaas, PhDThe 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 ...Brain; Dissections
412 Dry Eye Syndrome (Portuguese)NANOSPeople with abnormalities of the tear film are diagnosed with "dry eyes", but some patients with "dry eyes" may not feel that their eyes are "dry". Itching, burning, a scratchy sensation, a sensation that there is sand or grit in the eye, or intermittent blurring of the vision can all be symptoms of...Dry Eye Syndrome; Patient Brochure
413 Homonymous Hemianopia (Portuguese)NANOSThis refers to an absence of vision towards one side of the visual world in each eye. The damage that caused this problem is in the brain and not in the eyes.Homonymous Hemianopia; Patient Brochure
414 Microvascular Nerve Palsy (Portuguese)NANOSMicrovascular cranial nerve palsy is one of the most common causes of double vision in the older poulation. They are often referred to as "diabetic" palsies. They will resolve without leaving any double vision.Microvascular Nerve Palsy; Patient Brochure
415 Idiopatic Intracranial Hypertension (Portuguese)NANOSRaised intracranial pressure.Idiopathic Intracranial Hypertension; Patient Brochure
416 Migraine Enxaqueca (Portuguese)NANOSHeadache on one or both sides of the brain, and may include symptoms of nausea, vomiting, and sensitivity to light.Migraine; Patient Brochure
417 Meniere Disease (Portuguese)NANOSAbout Meniere disease.Meniere Disease; Patient Brochure
418 Hemifacial Spasm (Portuguese)NANOSInvoluntary contractions, called "spasms," of the muscles on one side of the face. The affected side of the face seems to "scrunch up" while the other side of the face remains normal.Hemifacial Spasm; Patient Brochure
419 Eyelid Myokymia (Portuguese)NANOSExcessive or anomalous eyelid closure.Eyelid Myokymia; Patient Brochure
420 Pituitary Tumor (Portuguese)NANOSPituitary tumors are benign (non-cancerous) overgrowth of cells that make up the pituitary gland (the master gland that regulates other glands in the body).Pituitary Tumor; Patient Brochure
421 Optic Disc Drusen (Portuguese)NANOSOptic disc drusen are abnormal deposits of protein-like material in the optic disc - the front part of the optic nerve.Optic Disc Drusen; Patient Brochure
422 Optic Neuritis (Portuguese)NANOSIn the most common form of optic neuritis, the optic nerve has been attacked by the body's overactive immune system and results in decreased vision.Optic Neuritis; Patient Brochure
423 Transient Visual Loss (Portuguese)NANOSAbout transient visual loss.Transient Visual Loss; Patient Brochure
424 Anterior Ischemic Optic Neuropathy (Portuguese)NANOSLoss of blood supply to the optic nerve results in diminished visual acuity.Anterior Ischemic Optic Neuropathy; Patient Brochure
425 Photophobia (Portuguese)NANOSThe symptoms of light sensitivity are: an uncomfortable sense of brightness, squinting, frequent blinking, and redness of the eye (especially if the eye is dry). Involuntary eye closure and excessive blinking is seen with blepharospasm. Individuals will tend to seclude themselves in darkness.Photophobia; Patient Brochure
