Cerebral Hemispheres — Flashcards

Flashcard 1: Types of white matter:_____ fibers: fibers passing to and from the brainstem to the cerebral cortex.

Answer: Projection

Flashcard 2: Neurons of the _____ cortex also known as area 6 are involved in planning of motor activities

Answer: premotor

Flashcard 3: The fibers in the corticospinal tract leave the cerebral cortex in the _____ limb of the internal capsule

Answer: posterior

Flashcard 4: Anterior cerebral artery and _____ artery supply the corpus callosum.

Answer: Posterior cerebral artery

Extra: The corpus callosum is supplied by both the Anterior Cerebral Artery (ACA) and the Posterior Cerebral Artery (PCA). - **ACA (Pericallosal artery):** Supplies the rostrum, genu, and body. - **PCA (Posterior pericallosal artery):** Supplies the splenium (the posterior-most part).

Flashcard 5: How many branches are given off by the internal carotid artery (ICA) in its cerebral part? Name them.

Answer: 5 branches::1. Ophthalmic artery 2. Posterior communicating artery 3. Anterior choroidal artery 4. Anterior cerebral artery (terminal) 5. Middle cerebral artery (terminal)

Extra: Mnemonic: **OPAAM** The cerebral (supraclinoid) part of the internal carotid artery begins after it pierces the dural roof of the cavernous sinus and the arachnoid mater. It then divides into its two terminal branches (ACA and MCA) in the vallecula of the lateral cerebral fissure.

Flashcard 6: Types of white matter:_____ fibers: connect various cortical regions within the same hemisphere

Answer: Association

Flashcard 7: The _____ of the corpus callosum connects frontal lobes

Answer: rostrum

Flashcard 8: The arrangement of cerebellar nuclei from _____ is dentate, emboliform, globose, and fastigial.

Answer: lateral to medial

Flashcard 9: ID Nucleus: _____

Answer: Dorsal motor nucleus of X - Adjacent and lateral to the hypoglossal nucleus

Flashcard 10: ID Cortical Area: _____

Answer: Wernicke's area (Brodmann area 22)
