5.1 - The Hindbrain, Midbrain and Forebrain Flashcards
(14 cards)
three components of the brain
5.1
- hindbrain
- midbrain
- forebrain
5.1
hindbrain composition
5.1
- cerebellum
- brain stem
- pons
- medulla
adjacent to the spinal chord
5.1
hindbrain function
5.1
- supports bodily functions
- link between spinal chord and brain
- movement and balance
5.1
medulla
5.1
a continuation of the spine which controls breathing, heartbeat and digestion
5.1
pons
5.1
sits above the medulla and receives information sent from visual areas to control eye and body actions
5.1
the cerebellum
5.1
walnut-shaped area that receives information from the pons. it coordinates sequence of body movement
midbrain
5.1
sits between the hindbrain and forebrain
responsible for sleep regulation, motor movement and arousal
includes reticular formation
5.1
reticular formation
5.1
inportant in control of arousal and in the sleeping and waking cycle
5.1
forebrain
5.1
includes cerebrum, hypothalamus and thalamus
5.1
cerebrum
5.1
covered by cerebral cortex, divided into the left and right cerebral hemispheres
5.1
amygdala
5.1
located: medial temporal lobe
purpose: emotion, aggression, implicit learning
5.1
hippocampus
5.1
located: mdeial temporal lobe
purpose: transfer of info from short-term memory to long term memory
5.1
hypothalamus
5.1
control of basic survival actions: sleep, regulation of body temperature, expression of emotions, four F’s
(feeding, fighting, fleeing and fornication)
5.1
thalamus
5.1
located: beneath cerebral cortex
- allows organisims to process sensory stimuli in the environment
- receives information from eyes, ears, skin (NOT NOSE)
- determines the importance of incoming sensory information
