Hindbrain structures
- 1. Cerebellum
- 2. Pons
- 3. Medulla
-
Cerebellum
- Part of hindbrain.
- Helps coordinate voluntary movement and balance.
-
Pons
- - Part of hindbrain.
- - Connects the cerebral cortex with the medulla.
- - Involved in arousal, sleep, daydreaming, waking, breathing and coordination of some muscle movements and motor tone.
-
Medulla
- Part of hindbrain.
- Responsible for regulating internal bodily systems necessary for survival, such as heart rate and breathing.
-
Main structures in midbrain
- 1. Basal ganglia
- 2. Reticular formation
-
Reticular formation
- Part of midbrain
- Filters and relays incoming sensory stimuli and redirects it to the cerebral cortex.
- This influences our state of physiological arousal and alertness.
-
Basal ganglia
- Part of midbrain
- Transmits motor
messages to and from the cerebral cortex. - Interconnected with the cerebral cortex, thalamus and brainstem
-
Forebrain structures
- 1. Cerebrum
- 2. Thalamus
- 3. Hypothalamus
-
Cerebrum
- Part of forebrain.
- The two large hemispheres that cover the brain.
-
Thalamus
- Part of forebrain.
- Redirects all sensory information
(except smell) to the appropriate sensory area of the cerebral cortex for processing.
-
Hypothalamus
- Part of forebrain.
- Responsible for regulating body temperature, sex drive, appetite and sleep-wake cycle (maintains homeostasis).
