Presentation 3.pptx about frontal lobe a

Ppt of frontal lobe and its functions

1. FRONTAL LOBE 

2. ANATOMY Frontal lobe extends from the frontal pole to central sulcus above the sylvain fissure Central sulcus separates the frontal lobe from parietal lobe. Precentral sulcus divides the frontal lobe from motor strips

3. SULCI AND GYRI On lateral aspects of frontal lobe 3 sulci are visible :precentral sulci,superior frontal sulci and inferior frontal frontal sulci In between these sulci 4 gyri present : A)Precentral gyrus :b/w central and precentral sulcus B)Superior frontal gyrus :superior to superior frontal sulcus C)Middle frontal gyrus :b/w superior and inferior frontal sulcus D)Inferior frontal gyrus: inferior to inferior frontal sulcus

4. On medial surface the frontal lobe extends down to the cingulate sulcus The paracentral lobule consists of the extensions of the precentral and post central gyri onto the medial hemispheric surface above cingulate sulcus it is imp. For bladder control The inferior frontal gyrus divided into pars orbitalis pars triangularis and pars operculularis On the medial surface lies olfactory sulcus and olfactory bulb and tract overlies this sulcus
