REVIEW: LAB2
• How are the lateral ventricles confluent with the 3rd ventricle?
• Answer– The foramen of
Monroe
REVIEW: LAB2
• What structure forms the walls of the third ventricle?
• Answer– The thalamus
REVIEW: LAB2
• Be sure that you understand the skewed "C" shape of the lateral ventricles.
REVIEW: LAB2
• Be sure that you understand the shape of the fornix
• Answer– The fornix is a white
matter fiber intra-hemispheric structure that connects the hippocampus to the mammillary bodies
hippocampi
REVIEW: LAB2
• How does CSF flow from the third and to the fourth ventricle?
• Answer– The cerebral
aqueduct
REVIEW: LAB2
• What is the relationship between the internal capsule and the cerebral peduncle?
• Answer– The internal capsule is a collection
of white matter fiber pathways– The cerebral peduncles are a
continuation of the internal capsule
REVIEW: LAB2
• Follow the optic tract
