Divisions of the brain

Dr. Morton provides an overview of the brain's divisions, including the cerebrum, diencephalon, brainstem, cerebellum, and corpus callosum. The cerebrum is associated with higher-order functions like thought and memory, while the diencephalon includes the thalamus and hypothalamus, which regulate sensory input and hormones. The brainstem, consisting of the midbrain, pons, and medulla, controls basic life functions. The cerebellum coordinates movement, and the corpus callosum connects the brain's hemispheres.

What is the primary function of the cerebrum?

• Controlling hormone release

• Processing thoughts and memory

• Coordinating muscle movements

• Regulating heart rate

Which lobe of the cerebrum is responsible for visual processing?

• Frontal lobe

• Parietal lobe

• Temporal lobe

• Occipital lobe

What is the role of the thalamus in the diencephalon?

• Regulating body temperature

• Secreting melatonin

• Acting as a gateway for sensory input

• Controlling voluntary movements

Which part of the brainstem is associated with cranial nerves III and IV?

• Cerebellum

• Midbrain

• Medulla oblongata

• Pons

What is the primary function of the pons in the brainstem?

• Processing visual information

• Regulating circadian rhythms

• Coordinating balance and posture

• Connecting the cerebellum to the brainstem

What is the main function of the cerebellum?

• Regulating hormone secretion

• Coordinating smooth muscle movements

• Processing auditory information

• Facilitating inter-hemispheric communication

What is the role of the corpus callosum?

• Regulating the sleep-wake cycle

• Processing sensory information

• Connecting the two cerebral hemispheres

• Coordinating voluntary movements
