QuestionChoice
Whilst this is a part of the internal capsule, corticobulbar fibres do not pass through the anterior limb. They pass through the middle of the internal capsule, the genu, before going on to synapse with cranial nerve nuclei.

A 45 year old male is seen in a specialist neurology clinic. For the past month, he has been experiencing difficulty chewing, swallowing and forming words. The clinician explains that the corticobulbar tract is responsible for the motor innervation of the head and neck muscles.

Through which part of the internal capsule do fibres of the corticobulbar tract pass?
