This document provides an overview of brain anatomy, beginning with the structures of the skull and meninges. It describes the major divisions of the brain including the forebrain, midbrain, and hindbrain. It outlines the lobes of the cerebral hemispheres and internal structures such as the basal ganglia and corpus callosum. Key structures such as the ventricles and cisterns are identified. The rest of the document illustrates various sections of the brain with labeled diagrams and MRI images.

2. APPROACH TO STUDY OF
BRAIN ANATOMY
SKULL VAULT, BASE & SUTURES.
MENINGES.
BRAIN PARENCHYMA.
CSF SPACES & CISTERN

3. SKULL VAULT

5. MENINGES
 DURAMATER :
 ARACHNOID MATER
 PIAMATER
 outer periosteal layer & inner meningeal layer

6. MENINGEAL FOLDS
 DURAL REFLECTIONS
DURAL VENOUS SINUSES
 FALX CEREBRI
B/W TWO DURAMATERS
 TENTORIUM CEREBELLI
FALX CEREBELLI
DIAPHRAGMATIC SELLA

8. BRAIN
 FOREBRAIN (PROSENCEPHALON)
 Telencephalon – Cerebral hemispheres.
 Diencephalon - Epithalamus,
Thalamus,
Hypothalamus and
Sub thalamus.
 MIDBRAIN ( MESENCEPHALON )
 HINDBRAIN ( RHOMBENCEPHALON)
 Metencephalon – pons and cerebellum.
 Myelencephalon – medulla.

9. CEREBRAL HEMISPHERES
 Outer gray matter : the cerebral cortex.
 inner white matter : centrum semiovale.
 Divided into lobes by four important sulci:
 Lateral (Sylvain fissure)
 Central (Rolandic fissure)
 Parieto - occipital and
 Calcarine sulcus.

10. LOBES OF BRAIN

11. CORPUS CALLOSUM: Thick band of white matter
connecting two hemispheres.
BASAL GANGLIA : central gray matter of telencephalon
consisting of lentiform nucleus, caudate nucleus,
claustrum & amygdala.
INTERNAL CAPSULE: Thick white matter band lying
between caudate nucleus, thalamus & lentiform nucleus.

13. MIDBRAIN
(MESENCEPHALON)
Smaller dorsal part - TECTUM
Larger ventral part - CEREBRAL PEDUNCLES
Interpeduncular fossa/cistern separate two
peduncles
Each cerebral peduncle -
CRUS & TEGMENTUM OF MIDBRAIN

14. Mid brain

15. HINDBRAIN
 PONS & MEDULLA OBLONGATA anteriorly
 CEREBELLUM posteriorly
 The fourth ventricle is present between the pons-medulla &
cerebellum

16. CSF SPACES
 LATERAL VENTRICLES (telencephalon)
 Foramina of monro
 THIRD VENTRICLE (diencephalon)
 Aqueduct of sylvius(MB)
 FOURTH VENTRICLE (hindbrain)
 Foramina of luschca & magendie
 FINALLY INTO THE SUBARACNOID SPACE

17. SUBARACHNOID CISTERNS
VENTRAL (median & paramedian)
Perimedullary
Prepontine
Suprasellar
Cp angle
DORSAL (median & paramedian)
Cisterna magna
Ambient Cistern
Supracerebellar
Quadrigeminal
Interhemispheric
