<prompt> Which of the following nerve fibers are present in the genu of internal capsule?Sensory fibres from thalamus to brainMotor fibres from lower limbMotor fibres from upper limbMotor fibres from trunk  <response>: Fibres travelling from the ventral posterior nuclei of the thalamus to the somatosensory area in the postcentral gyrus constitute the superior thalamic radiation. These fibres occupy the genu and posterior limb of the capsule. These fibres are third order sensory neurons responsible for conveying somesthetic sensations to the cerebral coex.
