Neuroanatomy Flashcards
What is the most common neurological disorder?
Stroke/Cerebrovascular disease.
What is the Prosencephalon?
The forebrain, consisting of the Telencephalon and Diencephalon.
What structures are in the Telencephalon?
Cerebral hemispheres.
What structures are in the Diencephalon?
Thalamus, hypothalamus.
What is the Mesencephalon?
The midbrain, consisting of the Tectum, Tegmentum, and Cerebral peduncles.
What is the Rhombencephalon?
The hindbrain, consisting of the Metencephalon (pons and cerebellum) and Myelencephalon (medulla).
What gets weird with anatomical directions in the brain?
Dorsal and ventral above the longitudinal axis.
Where is gray matter located?
In the cortex, containing cell bodies.
Where is white matter located?
Subcortical, containing axons.
What is the function of the Limbic Cortex?
Involved in processing emotions and some types of memory.
What is the function of the Insular Cortex?
Autonomic visceral functions and taste.
What is the function of the Precentral gyrus?
Primary Motor Cortex (4).
What is the function of the Postcentral gyrus?
Primary Somatosensory Cortex (1, 2, 3).
What is the function of the Lateral Fissure and Superior Temporal Gyrus?
Primary Auditory Cortex (41).
What is the function of the Calcarine sulcus?
Primary Visual Cortex (17).
What is the function of the Dorsolateral prefrontal cortex?
Areas 8, 9, and 46 are involved in higher cognitive functions like working memory.
What is the function of the Parietotemporal cortex?
Areas 39, 40, 7, 9, 21, 22, 37 are involved in sensory integration and attention.
What is the role of the Thalamus?
Acts as a relay station, receiving and processing information from various systems and relaying it to the cerebral cortex.
What information does the Spinothalamic Pathway carry?
Pain and temperature.
What information does the Dorsal Column Medial Lemniscus carry?
Touch and proprioception.
What is the function of the Basilar region of the brainstem?
Ventral, containing descending motor tracts.
What is the function of the Tegmentum of the brainstem?
Dorsal, containing ascending sensory tracts.
What is the role of the Rostral/Ascending RAS?
Consciousness and arousal, located in the midbrain and upper pons.
What is the primary function of the Cerebellum?
Coordination.
How do Cerebellar lesions affect function?
They affect ipsilateral function.
What are the anatomical divisions of the Cerebellum?
Vermis, Paravermis, and Lateral hemispheres.
What does subcortical white matter consist of?
Projection fibers, association fibers, and commissure fibers.
What structures make up the Striatum?
Caudate and Putamen.
What is the function of the Striatum and Subthalamic Nuclei?
They act as input structures.
What structures make up the Lentiform nucleus?
Globus Pallidus and Putamen.
What structures are affected by spinal cord injuries?
Peripheral nerves and spinal tracts, depending on the level and extent of the injury.
What is the role of cerebrospinal fluid (CSF)?
Provides cushioning and buoyancy for the brain and spinal cord, removing waste and delivering nutrients.
What is the primary function of the visual system?
Processing visual information from the eyes to the brain.
What is the primary function of the vestibular system?
Maintaining balance and spatial orientation.
