Fourth ventricle and choroid plexus

What is the Fourth ventricle?

• A cavity in the brain
• A structure in the spinal cord
• A part of the inner ear
• A gland in the body

What is the shape of the Fourth ventricle?

• Round
• Irregular
• Square
• Triangular

What is the location of the Fourth ventricle in the brain?

• Frontal lobe
• Temporal lobe
• Parietal lobe
• Hindbrain

What is the Choroid plexus?

• A network of blood vessels
• A layer of the brain
• A structure in the ear
• A gland in the body

What is the function of the Choroid plexus?

• Controls blood pressure
• Filters cerebrospinal fluid
• Regulates metabolism
• Controls heart rate

What is the relationship between the Choroid plexus and the Fourth ventricle?

• Separate
• Connected
• Interconnected
• Not related

What is the role of the Fourth ventricle in the brain?

• Controls memory
• Regulates mood
• Produces hormones
• Regulates cerebrospinal fluid

What is the effect of damage to the Choroid plexus on the brain?

• Causes headaches
• Impairs memory
• Increases risk of infection
• Has no effect

How does the Fourth ventricle and the Choroid plexus work together to regulate cerebrospinal fluid?

• The Choroid plexus produces cerebrospinal fluid and the Fourth ventricle removes it
• The Fourth ventricle produces cerebrospinal fluid and the Choroid plexus removes it
• They work independently to regulate cerebrospinal fluid
• They have no effect on cerebrospinal fluid

What happens if there is an overproduction of cerebrospinal fluid in the Choroid plexus?

• Increases pressure in the Fourth ventricle
• Decreases pressure in the Fourth ventricle
• Has no effect on the Fourth ventricle
• Increases pressure in the spinal cord
