Cerebral Arteries
This is a circle of arteries that surrounds the optic chiasm, holding the circular shape to ensure that if one side is not function that both hemispheres can be supplied.
What is the Circle of Willis?
This is located to the posterior third of the temporal lobe of the left hemisphere and it functions in language reception and comprehension.
What is Wernicke's Area?
This is the space between the Arachnoid and the Pia Mater that is filled with CSF, blood vessels and trabeculae.
What is Subarachnoid Space?
This is caused by an area of the brain dying due to being denied oxygen for one hour or less.
What is Tissue Necrosis?
This is a deep sulcus that demarcates a separation between the right and left hemispheres of the brain.
What is Longitudinal Fissure?
This artery supplies that cerebral hemispheres?
What is the Internal Cerebral Artery?
This is the main area of the brain that processes sound intensity and frequency.
What is the Auditory Cortex?
Thinnest layer of the meninges that adheres to the gyri and sulci of the surface tissues of the brain.
What is the Pia Mater?
This type of stroke is when a blockage breaks off and travels to a more narrow section of the veinous system, causing a blockage.
What is a Embolism (Ischemic) Stroke?
This lobe is located to the anterior portion, and is important for the function of gross motor movements and executive functions.
What is the Frontal Lobe?
This artery supplies the brainstem, cerebellum, occipital lobe and temporal lobe that join to form the basilar artery.
What is the Vertebral Artery?
This area communicates with the primary motor cortex and functions in processing sensory information such as taste, smell, touch, temperature changes and proprioception.
This is the only meninge layer that is sensitive to pain, being one source of headaches due to the increased sensitivity of the blood vessels of this area.
What is the Dura Mater?
This damage occurs from a hemorrhagic stroke that causes a collection of blood between the Dura Mater and the Arachnoid Mater.
What is a Subdural Hematoma?
This lobe is located to the posterior portion of the brain, and its sole function is for vision.
What is the Occipital Lobe?
This vein collects blood from the cerebral cortex and subcortical white matter and it drains to the dural venous sinuses.
What is the Superficial Cerebral Veins?
This is caused by damage to the somatosensory association cortex, that causes an inability to recognize 3D forms through touch.
What is Astereognosis?
These are lacey, web-like support structures located in the subarachnoid space.
What are Trabeculae?
This is when abnormal ballooning of the artery wall occurs, that can rupture causing a severe headache that onsets rapidly and if left untreated can lead to possible death.
What is an Aneurysms?
This lobe is located to the lateral portions of the brain, and is important in the function of auditory processing of information, as well as the structure and meaning of language.
What is the Temporal Lobe?
This artery is important for speech and language, as it supplies the lateral portions of the hemispheres, including internal structures such as the basal ganglia and internal capsule.
What is the Middle Cerebral Artery?
This focal point of Broca's area is important for initiating and coordinating speech organs for the production of language, due to being located near motor areas.
What is the Pars Opercularis?
The specific layer of the Dura Mater that is attached to the surface of the arachnoid mater, that contains dural venous sinuses that collect venous blood and drain it from the brain.
What is the Meningeal Layer?
This is a temporary loss of blood flow to the brain, that is typically restored within minutes or 24 hours.
What is a Transient Ischemic Attack?
This is an interhemispheric fiber, that connects homologous areas of the brain across the midline.
What is a Commissural Fiber?
