The Normal Unfixed Brain: Neuroanatomy Video Lab - Brain Dissections | Suzanne S. Stensaas, PhD | The 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 |

Olfactory System: Neuroanatomy Video Lab - Brain Dissections | Suzanne S. Stensaas, PhD | Beginning 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 |

Orientation: The Planes of the Brain: Neuroanatomy Video Lab - Brain Dissections | Suzanne S. Stensaas, PhD | Terms 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 |

Photophobia (Portuguese) | NANOS | The 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 |

|
Pituitary Tumor (Portuguese) | NANOS | Pituitary 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 |

Sensation from the Body: Neuroanatomy Video Lab - Brain Dissections | Suzanne S. Stensaas, PhD | Sensation 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... | Spinothalamic Tract; Anterolateral System; Dorsal Column-Medical Lemniscus Pathway; Body Sensation' Brain' Dissection |

|
Sensation from the Face: Neuroanatomy Video Lab - Brain Dissections | Suzanne S. Stensaas, PhD | Sensation 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... | Brain; Dissections |

|
The Spinal Cord & Monosynaptic Reflex: Neuroanatomy Video Lab - Brain Dissections | Suzanne S. Stensaas, PhD | The 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 |

|
Three Critical Vertical Pathways: Neuroanatomy Video Lab - Brain Dissections | Suzanne S. Stensaas, PhD | There 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 |

The Ventricles: Neuroanatomy Video Lab - Brain Dissections | Suzanne S. Stensaas, PhD | The ventricles are demonstrated and named on a model cast as well as in rotating 3D reconstructions. The production, function, circulation and removal of CSF produced by the choroid plexus is discussed using a diagram and then reviewed on frontal, axial and sagittal brain specimens and corresponding... | Ventricles; Brain; Dissection |
