FRONTAL LOBE Frontal lobe lies anterior to the central sulcus and superior to the sylvian fissure.

PARIETAL LOBE Behind the central sulcus, and above the lateral fissure, lies the parietal lobe. Its most anterior part is the postcentral gyrus, which is the site of the primary somatosensory cortex.(Broadmann’s 3,1,2) Somesthetic association area occupies superior parietal lobule(Broadmann’s 5,7) Somatotopic representation

OCCIPITAL LOBE The occipital lobe is the smallest lobe
It is separated from the parietal and temporal lobes on the medial surface by the parieto-occipital sulcus and on the lateral side by the lateral parietotemporal line The tentorium cerebelli forms its inferior border and the occipital bone its posterior margin.
27
OCCIPITAL LOBE 1.Primary visual area Broadmann’s area 17
Walls of the posterior part of the calcarine sulcus Receives fibers from lateral geniculate body 2.Secondary visual area Broadmann’s areas 18 and 19 Surrounds the primary visual area Interpret and relate the visual information received by primary visual area
30
CEREBELLUM Latin for ‘little brain’ Largest part of hindbrain
Occupies most of posterior cranial fossa Lies behind pons & medulla forming roof of 4th ventricle Separated from posterior part of cerebrum by tentorium cerebelli

Diagram depicting the anatomical position of cerebellum
32
Connection with the brainstem
Superior Cerebellar Peduncle (brachium conjunctivum) Connects with midbrain Middle Cerebellar Peduncle (brachium pontis) Connects with pons Inferior Cerebellar Peduncle (restiform body) Connects with medulla
33
External features Two cerebellar hemispheres . Median vermis.
Two surfaces ----superior and inferior 3 fissures: fissura prima, horizontal fissure and posterolateral fissure 3 lobes in each hemisphere anterior , posterior and flocculonodular.
34
Flattened view of the cerebellar cortex showing the main cerebellar lobes, lobules, and fissures. B: Relationship between the diagram in (A) and the cerebellum. (courtesy- snell’s clinical neuroanatomy)
