S01 - Topography of the Major Features of the Brain and Spinal Cord
Recognise the major features of the anatomy of
the brain and spinal cord as seen externally and
in coronal and transverse sections and
summarise the major functions of these areas

Planning
Brainstem
Medulla
Pons
Midbrain
Tegmentum

Limbic System
Thalamus
Hypothalamus
Describe the major functions of the
cerebral cortex, cerebral white
matter, basal ganglia, diencephalon,
brainstem and cerebellum
Cerebral Cortex
Cerebral white matter
Due to myelinated axons - signals
Basal Ganglia
Voluntary control
Action Selection
Which action to select at any one time
Habits
Emotional
Diencephalon
Thalamus
Junctional area for sensory neurones
Hypothalamus
Controls visceral autonomic
nervous system
e.g. fight or flight response
Pineal Gland
Controls circadian rhythm
Pituitary Gland
Endocrine function
Brainstem
Pons
Switchboard connecting
cerebellum to cerebral cortex
Latin for bridge
Medulla
Decussation occurs here
Relay information
Touch
Taste
Hearing
Cerebellum
Movement centre
Identify normal anatomical
features of the brain on images
produced by CT and MRI scanning
CT Scan
MRI scan
Identify and describe the blood supply to and
from the brain and spinal cord on specimens
and angiograms and appreciate its clinical
significance

of the cerebellum and brainstem from
external views including the attachments
of cranial nerves.
