CSF System Flashcards
(24 cards)
What is the primary function of the ventricular system in the brain?
To produce and circulate cerebrospinal fluid (CSF).
How many ventricles are there in the human brain?
There are four ventricles.
What are the names of the four ventricles in the brain?
Lateral ventricles, third ventricle, fourth ventricle.
True or False: The lateral ventricles are located in the brainstem.
False.
What connects the lateral ventricles to the third ventricle?
The interventricular foramen (foramen of Monro).
Fill in the blank: The third ventricle is located between the __________.
two halves of the thalamus.
What is the function of the fourth ventricle?
To connect the brain to the spinal cord and help circulate CSF.
What aqueduct connects the third and fourth ventricles?
Cerebral aqueduct (aqueduct of Sylvius).
True or False: The ventricles are filled with blood.
False.
What is the primary component of cerebrospinal fluid (CSF)?
Water.
Multiple Choice: Which of the following structures is not part of the ventricular system? A) Lateral ventricle B) Cerebral aqueduct C) Hippocampus
C) Hippocampus.
What is the role of the choroid plexus?
To produce cerebrospinal fluid (CSF).
Fill in the blank: CSF is reabsorbed into the bloodstream through the __________.
arachnoid granulations.
True or False: The lateral ventricles are the largest ventricles in the brain.
True.
What is the condition called when there is an accumulation of CSF in the ventricles?
Hydrocephalus.
What is the primary route for CSF to flow from the fourth ventricle to the spinal canal?
The central canal.
Multiple Choice: Which ventricle is shaped like a butterfly? A) Third ventricle B) Lateral ventricle C) Fourth ventricle
B) Lateral ventricle.
What structure separates the lateral ventricles?
The septum pellucidum.
Fill in the blank: The __________ is a narrow channel that runs through the midbrain.
cerebral aqueduct.
What is the main purpose of cerebrospinal fluid (CSF) in the brain?
To cushion the brain and provide buoyancy.
True or False: The fourth ventricle is located anterior to the cerebellum.
True.
What is the term for the area where the CSF flows from the fourth ventricle into the subarachnoid space?
Median and lateral apertures (foramina of Magendie and Luschka).
Fill in the blank: The __________ connects the two lateral ventricles.
interventricular foramen.
What is the significance of the blood-brain barrier in relation to the ventricular system?
It protects the brain from harmful substances while allowing CSF to circulate.
