pain receptors, what are the possible
explanations for head pain?
What is the function of the dural
sinuses?
1
Spinal Meninges
Dura mater
Epidural space
Pia mater
Indicate the
anterior
(ventral) side in
this view.
Subarachnoid space
Where are the
dorsal root
ganglia?
Vertebral body
Ventricles of the Brain
What is the function of CSF?
(Be sure to study the ventricle model in the lab.)
2
Circulation of
CSF
Where is CSF made?
Describe the chemical
composition of CSF.
How is CSF “recycled”?
Olfactory bulbs and tracts
develop in the Telencephalon
Lateral ventricles develop
in the Telencephalon
Cerebral hemispheres
Developments of the
Telencephalon
What tissue
passes through
the middle of the
third ventricle?
3
Telencephalon: The Cerebrum
List some of the
functions of the
cerebrum.
Are the functions
of both
hemispheres
identical?
Functional Areas of the
Cerebral Cortex
List and briefly describe the 4 types of functional areas.
4
Motor Pathways of the SNS and ANS
Which is the post-ganglionic fiber?
Telencephalon: Basal Nuclei
(Basal Ganglia)
Describe the location of the basal nuclei relative
to the cerebral cortex, thalamus and
hypothalamus. What does this structural feature
imply about the function of the basal nuclei?
5
Developments from the Diencephalon
Which ventricle is found in the diencephalon?
Describe the structure and function of the
reticular formation (RAS).
Pineal gland
Thalamus
Hypothalamus
Not shown:
Neurohypophysis
Optic nerves and tracts
The Reticular Formation and RAS
What information is
received by the
reticular formation?
How is that
information used?
Where does
awareness of
sensation occur,
and how is this
different from
sensation, and
perception?
6
The Limbic System
Fornix
Thalamus
Hypothalamus
(mammillary bodies)
Basal ganglia
(caudate nucleus)
Olfactory pathway
Cerebral cortex
Which areas are part of our conscious mind? Which are
unconscious areas of the brain?
Describe examples of how activity in the limbic system may affect
autonomic functions.
Developments from the
Mesencephalon (Midbrain)
Corpora quadrigemina
Cerebral
peduncle

Trochlear N. (IV)
Identify the pineal
gland of the
diencephalon.
Cerebral aqueduct
What features of the hindbrain are
visible in this figure?
7
Developments of the
Rhombencephalon
(Hindbrain)
Cerebellar
The reticular formation extends
peduncles from the spinal cord to the
diencephalon (thalamus). Name the
brain structures in which this
neuron “network” is found.
4th ventricle
Cerebellum
What kinds of information are
sent to the cerebellum, and how
is this related to its function?
Pons
Medulla oblongata
Name the important nuclei (control
centers) in the pons and medulla.
