CSF syste Flashcards
(13 cards)
What are the components of the lateral ventricle?
Anterior/frontal horn, body, atrium/trigone, posterior/occipital horn, inferior/temporal horn
These components are essential for understanding the structure of the lateral ventricle.
What is the interventricular foramen also known as?
Foramen of Monro
The interventricular foramen connects the lateral ventricles to the third ventricle.
What is the structure that connects the third ventricle to the fourth ventricle?
Cerebral aqueduct
The cerebral aqueduct is a narrow channel in the brainstem.
What are the apertures of the fourth ventricle?
Lateral aperture (Foramen of Luschka), Median aperture (Foramen of Magendie)
These apertures allow cerebrospinal fluid to flow from the fourth ventricle to the subarachnoid space.
What is a cistern in the context of the CNS?
A cistern is a space within the subarachnoid space where cerebrospinal fluid collects.
Cisterns are important for the circulation of cerebrospinal fluid.
Identify the locations of the following cisterns: __________, __________, and __________.
Cisterna magna, Quadrigeminal cistern, Interpeduncular cistern
These cisterns are critical for understanding the flow of cerebrospinal fluid.
What are the three layers of cranial meninges?
Dura mater, Arachnoid mater, Pia mater
These layers protect the brain and contain cerebrospinal fluid.
What are the meningeal spaces surrounding the brain?
Epidural space, Subdural space, Subarachnoid space
Each space has different clinical significance in conditions such as hemorrhage.
Where is the falx cerebri located?
It is located between the two cerebral hemispheres.
The falx cerebri is a dural fold that helps to stabilize the brain.
What are the dural folds identified in the brain?
Falx cerebri, Falx cerebelli, Tentorium cerebelli
These folds separate different parts of the brain and provide structural support.
Describe the anatomy of the spinal cord.
Location in the vertebral canal, names of spinal cord segments, relationship between spinal segments, spinal nerves, and vertebrae, location of conus medullaris.
Understanding spinal cord anatomy is crucial for diagnosing spinal cord injuries and diseases.
What is the relationship between spinal segments and vertebrae?
Spinal segments correspond to pairs of spinal nerves that exit between vertebrae.
There are more vertebrae than spinal segments due to the arrangement of spinal nerves.
What is the location of the conus medullaris during adulthood?
It is located at the level of the first or second lumbar vertebra.
This is significant for lumbar puncture procedures.
