multiple cholce question
ventricles are cavities found in the ____ and are filled with ____.
o spinal cord; cerebrospinal fluid
o spinal cord; blood
o brain; cerebrospinal fluid
o brain; blood

Explanation:

Ventricles are cavities located within the brain (not the spinal cord, where the central canal is different). These brain ventricles are filled with cerebrospinal fluid, which has protective and nutritive functions for the brain. Blood is not the substance filling the ventricles. So the correct option is the one with "brain" and "cerebrospinal fluid".

Answer:

C. brain; cerebrospinal fluid (assuming the options are labeled A, B, C, D with C being "brain; cerebrospinal fluid" as per the options provided)
