Cerebellum

Medically reviewed byDr Fred UshakovSpecialist in Fetal Medicine & Obstetric Ultrasound · 10 July 2026

Incredible shot of the Cerebellum at just 11 weeks in our recent instagram post!

This fetus is just 4cm long, but our advanced transvaginal probes are able to get this high resolution image of the cerebellum. Latin for ‘little brain’, the cerebellum is an important structure at the back of the human skull. The cerebellum is responsible for coordinating our voluntary movements, as well as motor skills, balance, coordination and posture.

It consists of two major structures namely the Cerebellar cortex and Cerebellar nuclei. Despite only being 10% of the human brain, the ‘little brain’ contains up to 80% of the brain’s neurons, mainly in the cortex. Neurons are important cells in the human body that are the building blocks of the nervous system.

You can see why it is important to check the development of the brain. Dr Fred Ushakov is a specialist in neurosonography and conducts a comprehensive examination of the brain with every scan from 11 weeks until the 3rd trimester.
