(a) Brain Structure and Function Quiz

Brain Structure and Function

• The longitudinal fissure divides the cerebrum into right and left cerebral hemispheres.

Brain Regions

• The cerebrum is the largest and most complex part of the human brain.
• The three main regions of the brain are the forebrain, midbrain, and hindbrain.

Brainstem

• The mesencephalon is located between the thalamus/hypothalamus of the forebrain and the pons of the hindbrain.

Diencephalon

• The epithalamus forms the thin roof of the cavity enclosed by the diencephalon.

Corpus Callosum

• The corpus callosum is a bundle of nerve fibers that facilitates communication between the right and left cerebral hemispheres.

Olfactory System

• The olfactory lobes are located in the forebrain.

Thalamus

• The thalamus relays sensory information from the senses (except smell) to the cerebrum.

Pons Varolii

• The pons varolii (part of the brainstem) plays a crucial role in controlling sleep and arousal.
