The Brain Flashcards
the 3 Parts of the brain?
Hindbrain, Mid-brain, fore-brain.
Hindbrain
located at the rear base of the skull and includes, the Cerebellum, the Medulla, Pons.
Mid-brain
small part of the brain above the pons that arouses the brain. integrates sensory info and relays in upwards. the Midbrain, the Medulla, Pons compose most of the “brain stem” and the “reticular activating system” (RAS)
Fore-brain
covers the central core. the outer layer of the forebrain is the cerebral cortex. the inner layer is the Cerebrum.
The Medulla
- controls breathing, heart rate and reflexes.
Pons
- functions as a bridge between spinal cord and the brain to produce chemicals for sleep.
Reticular activating system (RAS)
alerts the brain to incoming signals and regulates sleep and wake cycles.
Cerebral cortex
responsible for higher thinking processes ability to learn, read, see understand and store info.
the Limbic system
regulates our emotions and motivation- contains the hypothalamus, amygdala, thalamus and hippocampus.
The Thalamus
which integrates all sensory input expect smell and relays info to and from the cortex.
Hypothalamus
located just below the Thalamus, controls hunger, thirst, sexual behaviour and reactions too temperature.
Amygdala
controls emotions like rage and anger, “lack of empathy”
Hippocampus
helps in formation of memories
the 4 lobes/ regions the brain
1-the occipital lobe, 2-parietal lobe, 3-temporal lobe, 4-frontal lobe.
the lobes the brain
the cerebrum is made of two hemisphere (sides) connected by fibres called “corpus callosum”. the hemisphere are then divided into lobes or regions.
