1.4 neuro - ventricles

Question 1

What are the ventricles formed from

Answer 1

The lumen of the neural tube

Question 2

What part of the CNS are the lateral ventricles associated with

Answer 2

Cerebral hemispheres

Question 3

What part of the CNS is the 3rd ventricle associated with

Answer 3

Diencephalon - found between the hemispheres

Question 4

What part of the CNS is the 4th ventricle associated with

Answer 4

Pons and medulla

Question 5

What part of the CNS is the cerebral aqueduct associated with

Answer 5

Midbrain

Question 6

What part of the CNS is the central canal of the ventricles associated with

Answer 6

Spinal cord

Question 7

Function and location of the choroid plexus

Answer 7

In the ventricles; produce CSF

Question 8

Function and location of the CSF

Answer 8

Ventricles and subarachnoid space; prevents weight of brain from pressing nerves and blood vessels on base of skull

Question 9

Subdivisions of the lateral ventricles and their associated lobe

Answer 9

Anterior horn, frontal lobe; Posterior horn, occipital lobe; Inferior horn, temporal lobe

Question 10

Passageway between the lateral ventricles and 3rd ventricle

Answer 10

Interventricular foramina

Question 11

Massa intermedia

Answer 11

Band of tissue in the 3rd ventricle

Question 12

Passageway between the 3rd ventricle and 4th ventricle

Answer 12

Cerebral aqueduct

Question 13

Function of the medial and lateral apertures of the 4th ventricle

Answer 13

Openings in the 4th ventricle that allow CSF to flow into the subarachnoid space; 2 lateral aperture in each lateral recesses and 1 medial

Question 14

Complete pathway of CSF flow

Answer 14

Lateral ventricles, interventricular foramen, 3rd ventricle, cerebral aqueduct, 4th ventricle, subarachnoid space, absorbed by arachnoid granulations, return to venous circulation, arterial capillaries, filtered / produced by choroid plexus, back to ventricles
