Intermediate Frontal Lobe Quiz

Q1. What is the frontal operculum?

• Occipital cortex surrounding the calcarine sulcus
• Frontal cortex that overlies the insula
• Medial parietal cortex surrounding the precuneus
• Temporal cortex forming the uncus

Q2. Which three parts subdivide the inferior frontal gyrus?

• Precentral, central, and postcentral parts
• Superior, middle, and inferior parts only
• Pars orbitalis, pars triangularis, and pars opercularis
• Cuneus, precuneus, and lingual parts

Q3. Where is the premotor cortex located relative to the primary motor cortex?

• Posterior to the postcentral gyrus
• Anterior to the primary motor cortex
• Within the occipital lobe
• Deep to the thalamus

Q4. Where is the supplementary motor area located?

• Medial superior frontal cortex
• Inferior temporal cortex
• Posterior insular cortex
• Lateral occipital cortex

Q5. Which frontal cortical region is classically associated with voluntary conjugate eye movements?

• Frontal eye field
• Primary auditory cortex
• Calcarine cortex
• Vestibular nuclei

Q6. Which surface of the frontal lobe rests on the orbital plates of the frontal bone?

• Tentorial temporal surface
• Medial occipital surface
• Orbital surface
• Posterior parietal surface

Q7. Which sulcus on the orbital frontal surface contains the olfactory tract?

• Central sulcus
• Calcarine sulcus
• Olfactory sulcus
• Intraparietal sulcus

Q8. Which gyrus lies medial to the olfactory sulcus?

• Gyrus rectus
• Supramarginal gyrus
• Angular gyrus
• Lingual gyrus

Q9. How is the primary motor cortex somatotopically organized?

• All body muscles are represented equally at one cortical point
• Different cortical regions represent different body parts
• Only the face has cortical representation
• Motor representation is confined to the temporal lobe

Q10. Which major descending pathway arises substantially from frontal motor areas and conveys voluntary motor commands?

• Corticospinal tract
• Medial lemniscus
• Spinothalamic tract
• Optic radiation
