Brain Anatomy Quiz: Gyri, Sulci, Basal Nuclei, and Diencephalon

Brain Structure and Functions

• The cerebrum constitutes 80% of the total brain weight.
• The outer layer of the cerebrum is called the cerebral cortex.
• The brainstem is responsible for subconsciously regulating the internal environment.
• The cerebellum is NOT included in the forebrain.
• The cerebellum is involved in the coordination of voluntary movements and balance.
• The vestibular system in the inner ear, along with the cerebellum, is responsible for the balance of the body.
• The thalamus plays a role in transmitting sensory information to the cerebral cortex.
• The thalamus functions as a relay station for sensory information.

Brain Components and Functions

• The white matter in the cerebral cortex mainly consists of myelinated axons.
• The cerebellum is involved in subconscious actions.
• The hypothalamus is responsible for regulating body temperature and thirst.
• Most cranial nerves originate from the brainstem.
• The Primary Motor Cortex is located in the frontal lobe of the cerebrum.
• The occipital lobe is responsible for vision.
• Damage to the right motor cortex results in paralysis or weakness on the left side of the body.
• The Area of Smell is located in the temporal lobe of the cerebrum.
• The parietal lobe contains the Somato Sensory Cortex.
