- It is the connective pathway between the left and the right side of the brain.
- It is responsible for transmitting neural messages between both the hemispheres
- The corpus callosum sits in the centre of the brain, measures around 10 cm in length and is shaped like the letter C
- It is the anterior end, lies 4 cm behind frontal pole
- Anteriorly-anterior cerebral arteries
- Posteriorly-anterior horn of lateral ventricle.
- Directed downwards and backwards from genu
- Ends by joining lamina terminalis, in front of anterior commissure
- Superiorly-anterior horn of lateral ventricle
- Inferiorly-indusium griseum and longitudinal striae
- Middle part between genu and splenium
Forms roof of central part of lateral ventricle
anterior cerebral arteries
Lower border of falx cerebri
Overlapped by cingulate gyrus and covered by Indusium griseum, longitudinal striae.
provides attachment to septum pellucidum, fornix
- Post. end (thickest part of cc), lies 6 cm in front of occipital pole
Tela choroidea of the third ventricle, the pulvinar, the tectum, the pineal body
Inferior sagittal sinus and falx cerebri
Great cerebral vein, straight sinus and free margin of tentorium cerebelli
- Connects orbital surfaces of two frontal lobes
- Made of fibres of genu
- Connects two frontal lobes
- Made of fibres of splenium
- Connects the two occipital lobes
Agenesis of corpus callosum
- It is a congenital (lifelong) brain abnormality that occurs when the corpus callosum does not develop as it should during the early prenatal period.
- It can occur as an isolated condition or in association with other brain abnormalities or physical or medical condition.
