Test How Deep Your Knowledge Is On Brain Ventricles

2.

Lateral ventricles are connected to the 3rd ventricle by the

Interventricular foramen
Cerebral aqueduct
Choroid plexus

Correct Answer

A. Interventricular foramen

Explanation

The interventricular foramen is the correct answer because it is the structure that connects the lateral ventricles to the third ventricle in the brain. The interventricular foramen allows for the flow of cerebrospinal fluid between these ventricles, which is important for maintaining the balance and pressure within the brain. The cerebral aqueduct and choroid plexus are not directly involved in connecting the lateral ventricles to the third ventricle.

Four ventricles are

Lt lateral; Rt lateral; 3rd ventricle and 4th ventricle
1 & 2 lateral; 3 &4 ventricle
Interconnected cavities

Correct Answer

A. Lt lateral; Rt lateral; 3rd ventricle and 4th ventricle

Explanation

The correct answer is Lt lateral; Rt lateral; 3rd ventricle and 4th ventricle. This answer is correct because it accurately identifies the four ventricles in the brain. The lateral ventricles are located in the cerebral hemispheres, with one in the left hemisphere and one in the right hemisphere. The third ventricle is located in the diencephalon, between the two halves of the thalamus. The fourth ventricle is located in the brainstem, between the pons and the cerebellum. These interconnected cavities play a crucial role in the production and circulation of cerebrospinal fluid.

4.

Lateral ventricles are larger than the 3rd and the 4th ventricle

True
False

Correct Answer

A. True

Explanation

The statement is true because the lateral ventricles are the largest ventricles in the brain, located in the cerebral hemispheres. They are responsible for producing and circulating cerebrospinal fluid (CSF). On the other hand, the 3rd and 4th ventricles are smaller and located in the midbrain and hindbrain, respectively. They also produce and circulate CSF but are smaller in size compared to the lateral ventricles. Therefore, it can be concluded that the lateral ventricles are indeed larger than the 3rd and 4th ventricles.

Interconnected cavities inside the brain are brain ventricles

True
False

Correct Answer

A. True

Explanation

The interconnected cavities inside the brain are known as brain ventricles. These ventricles are responsible for producing and circulating cerebrospinal fluid, which helps to protect and nourish the brain. The ventricles also play a role in maintaining the brain's overall structure and providing a pathway for the exchange of nutrients and waste products. Therefore, the statement is true.

6.

Lateral ventricles are connected to the 3rd ventricle by

Interventricular Foramen
Aperture of Magendie
Cerebral Aqueduct

Correct Answer

A. Interventricular Foramen

Explanation

The correct answer is Interventricular Foramen. The lateral ventricles are connected to the 3rd ventricle through the Interventricular Foramen, also known as the Foramen of Monro. This small opening allows the flow of cerebrospinal fluid between the lateral ventricles and the 3rd ventricle, facilitating communication and circulation of the fluid within the brain.

The 3rd ventricle is connecgted to the 4th ventricle by

Choroids Plexus
Interventricular Foramen
Cerebral Aqueduct

Correct Answer

A. Cerebral Aqueduct

Explanation

The 3rd ventricle is connected to the 4th ventricle by the cerebral aqueduct. The cerebral aqueduct, also known as the aqueduct of Sylvius, is a narrow canal that runs through the midbrain, connecting the 3rd and 4th ventricles of the brain. It allows for the flow of cerebrospinal fluid (CSF) between these two ventricles, facilitating the circulation and drainage of CSF throughout the brain.

8.

Ventricles are lined by _____ (type of glial cells)

Ependyma
Serous
Basal

Correct Answer

A. Ependyma

Explanation

The correct answer is ependyma. Ependyma is a type of glial cell that lines the ventricles of the brain and the central canal of the spinal cord. These cells have cilia on their surface, which help in the movement of cerebrospinal fluid within the ventricles. Ependymal cells also play a role in the production and regulation of cerebrospinal fluid.

9.

Ventricles contain specialized capillary system called _____ that produce CSF

Cerebral Aqueduct
Choroids Plexus
Interventricular Foramen

Correct Answer

A. Choroids Plexus

Explanation

The correct answer is Choroids Plexus. The choroid plexus is a specialized capillary system found in the ventricles of the brain. It is responsible for producing cerebrospinal fluid (CSF), which helps cushion and protect the brain and spinal cord.

CSF enters the subarachonoid space through three openings in the 4th ventricles

On top & side
Median aperture/lateal aperture
Aperture of Magendie/Aperture of Lushka

Correct Answer

A. Aperture of Magendie/Aperture of Lushka

Explanation

The correct answer is Aperture of Magendie/Aperture of Lushka. CSF (cerebrospinal fluid) enters the subarachnoid space through three openings in the 4th ventricles, known as the Aperture of Magendie and Aperture of Lushka. These openings allow the CSF to flow from the ventricles into the subarachnoid space surrounding the brain and spinal cord. The CSF then circulates and provides cushioning and support to the central nervous system.

11.

Choroid plexus does not produce CSF from blood plasma

True
False

Correct Answer

A. False

Explanation

The choroid plexus is responsible for producing cerebrospinal fluid (CSF) from blood plasma. It is a network of blood vessels located in the ventricles of the brain. The choroid plexus filters blood plasma and secretes CSF, which serves as a protective and nourishing fluid for the brain and spinal cord. Therefore, the statement that the choroid plexus does not produce CSF from blood plasma is false.

Forms a pad around the CNS and protect it from shock; provides nutrition to surrounding tissues; helps the CNS to maintain its ionic balance; removes waste; hydrates brain tissue.

CSF functions
CNS functions
ASF funcitons

Correct Answer

A. CSF functions

Explanation

CSF (Cerebrospinal fluid) functions to form a protective pad around the central nervous system (CNS) in order to shield it from shock. It also provides nutrition to the surrounding tissues, helping to maintain their health. Additionally, CSF aids in maintaining the ionic balance of the CNS, ensuring proper functioning. It also plays a role in removing waste products and helps to hydrate the brain tissue.
