Structure of the brain
Function of the brain
Cerebrum (Cerebral cortex) – High order functions such as thinking, reasoning, learning,
memory, conscious awareness of surroundings
Corpus callosum – Communication between the two cerebral hemispheres by transmitting
neural messages
Cerebellum – Coordination of fine contractions of muscles resulting in smooth movements and
the maintenance of posture and balance
Hypothalamus – Homeostasis, regulation of the heart, digestive system, appetite, thirst,
metabolism, body temperature, response to fear or anger
Midbrain - Generates reflex movements of the head, eyes and body. Hearing, and maintains
muscle tone. Relays motor impulses from cortex to pons and sensory information from the
spinal cord to the thalamus
Pons - Respiration and sleep control. Relays impulses from left to right cerebellar
hemispheres and different parts of the brain to each other
Medulla oblongata – Under the influence of hypothalamus, regulates homeostasis e.g. heart,
breathing and diameter of blood vessels.
Spinal cord – provides a pathway for communication between muscles and glands in the brain.
Integration of autonomic, protective reflexes
Actions involved in the lobes

Document Summary
Cerebrum (cerebral cortex) high order functions such as thinking, reasoning, learning, memory, conscious awareness of surroundings. Corpus callosum communication between the two cerebral hemispheres by transmitting neural messages. Cerebellum coordination of fine contractions of muscles resulting in smooth movements and the maintenance of posture and balance. Hypothalamus homeostasis, regulation of the heart, digestive system, appetite, thirst, metabolism, body temperature, response to fear or anger. Midbrain - generates reflex movements of the head, eyes and body. Relays motor impulses from cortex to pons and sensory information from the spinal cord to the thalamus. Relays impulses from left to right cerebellar hemispheres and different parts of the brain to each other. Medulla oblongata under the influence of hypothalamus, regulates homeostasis e. g. heart, breathing and diameter of blood vessels. Spinal cord provides a pathway for communication between muscles and glands in the brain. Frontal lobe - involved in motor function, problem solving, spontaneity, memory, language, initiation, judgement, impulse control, social and sexual behaviour.
