Brain Part Specific Portion Functions
A) Cerebrum Primary Motor Cortex Broca's Area Primary Somatosensory Cortex
B) Association Areas Diencephalon Thalamus Hypothalamus Brain Stem
C) Midbrain Pons Medulla Oblongata
A)
- Cerebrum: Responsible for higher brain functions such as thought, memory, and reasoning.
- Primary Motor Cortex: Controls voluntary movement of skeletal muscles.
- Broca's Area: Responsible for speech production.
- Primary Somatosensory Cortex: Processes sensory information from all parts of the body.
B)
- Association Areas: Integrates information from multiple brain regions to form a cohesive perception or action.
- Diencephalon: Regulates body temperature, hunger, and thirst.
- Thalamus: Acts as a relay station for sensory information to the cerebral cortex.
- Hypothalamus: Regulates body temperature, hunger, thirst, and sexual behavior.
- Brain Stem: Controls basic life functions such as breathing, heart rate, and blood pressure.
C)
- Midbrain: Involved in visual and auditory reflexes.
- Pons: Regulates breathing, controls sleep, and relays sensory information between the cerebellum and cerebrum.
- Medulla Oblongata: Regulates vital functions such as heart rate, breathing, and blood pressure.
