Lateral Ventricle: Anatomy And Clinical Significance

Lateral Ventricle

Question 1. Write a short note on the lateral ventricle.
Answer.

• It is a C-shaped cavity within the cerebral hemisphere.
• There are two lateral ventricles, one in each cerebral hemisphere of the cerebrum.
• It is C-shaped and wraps itself around the thalamus, lentiform nucleus and caudate nucleus.
• Each lateral ventricle is situated lateral to the septum pellucidum and below the corpus callosum.
• It is lined by an ependyma and is filled with CSF.
• It has a capacity of about 7–10 mL.
• It communicates with the 3rd ventricle through the interventricular foramen (of Monro).

Lateral Ventricle Parts. Each lateral ventricle is divided into four parts:

• Central part/body
• Anterior horn
• Posterior horn
• Inferior horn

Lateral Ventricle Applied Anatomy The blockage of interventricular foramina leads to excessive accumulation of CSF in the lateral ventricles causing a clinical condition called hydrocephalus.
