Ventricular System Flashcards
Identify the 4 main parts of the Ventricular System.
● Left Lateral Ventricle
● Right Lateral Ventricle
● 3rd Ventricle
● 4th Ventricle
It is a fluid formed mainly in the choroid plexuses.
Cerebrospinal Fluid
They ensure continuous production of CSF.
Choroid Plexuses
The Cerebrospinal Fluid has a _ color.
Clear
What are the functions of CSF?
- Cushioning
- Nutrient Transport
- Waste Removal
- Homeostasis
This is a medical procedure used to collect cerebrospinal fluid (CSF) for detecting of infection or to relieve pressure in the spine or brain.
Spinal Tap or Lumbar Puncture
What can a CSF analysis help diagnose?
- Brain Infections (Meningitis)
- Subarachnoid Hemorrhage (Brain Bleeding)
What is a cerebrospinal fluid (CSF) leak?
The escape of CSF from the brain or spinal canal.
What does high White Blood Cells count mean in a CSF Analysis?
Your brain is fighting an infection.
It is the three layers of protective tissues that surround the brain and spinal cord.
Meninges
The outermost and toughest layer of the meninges, made of dense connective tissue, is called the:
Dura Matter
Which layer of the meninges is the innermost and most delicate, directly covering the brain and spinal cord?
Pia Matter
Meninges protect the ________ from physical trauma by acting as tough, protective covering.
Brain and Spinal Cord
Which layer of the meninges is thin, web-like, and located in the middle
Arachnoid Mater
What is Inflammation on the meninges caused by bacterial?
Meningitis
A slow growing usually begin at tumor that form meninges?
Meningioma
Use to detect issues hematoma or meningiomas?
CT/MRI
It refers to the abnormal expansion of the brain’s ventricles.
Ventricular Enlargement
What does the enlargement of the lateral ventricles in individuals with schizophrenia typically suggest?
Loss of brain tissue, especially in the frontal and temporal lobes.
In mood disorders like bipolar disorder and major depressive disorder, what might be linked to larger or irregularly shaped ventricles?
More severe or prolonged mood episodes and emotional regulation difficulties
The main function of meninges:
- Protection
- Support and Structure
Bleeding between the dura mater and arachnoid mater, usually caused by head trauma. It can put pressure on the brain and cause headaches, confusion, and loss of consciousness.
Subdural Hematoma
Bleeding in the subarachnoid space, often due to a ruptured aneurysm. It can cause a sudden severe headache, nausea, and loss of consciousness.
Subarachnoid Hemorrhage
is a condition where there is an abnormal buildup of CSF within the brain, leading to increased pressure and potentially causing brain damage.
Hydrocephalus
is a condition where the brain tissue extends down into the spinal canal, potentially causing pressure on the brainstem and spinal cord.
Chiari malformation
is a condition where fluid-filled cavities (syrinx) develop inside the spinal cord.
Syringomyelia
is a condition where there is increased pressure in the brain due to excess cerebrospinal fluid (CSF), but there is no clear cause (that’s why it’s called “idiopathic, “meaning unknown cause).
Idiopathic Intracranial Hypertension (IIH)
