Intermediate Frontal Lobe Quiz

Q1. What is the frontal operculum?

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

Q2. Which three parts subdivide the inferior frontal gyrus?

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

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

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

Q4. Where is the supplementary motor area located?

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

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

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

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

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

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

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

Q8. Which gyrus lies medial to the olfactory sulcus?

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

Q9. How is the primary motor cortex somatotopically organized?

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

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

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