Chapter 5- The Brain Flashcards
What is the HINDBRAIN made up of?
Medulla
Pons
Cerebellum
What is the FOREBRAIN made up of?
Thalamus
Hypothalamus
Cerebrum
What is the MIDBRAIN made up of?
The reticular formation
Where and what is the PONS responsible for?
Sits above the medulla, is a continuation of the spine.
receives info from the visuals to control eyes and body actions
Where and What is the MEDULLA responsible for?
First part of the continuation of the spine
It’s role is to control breathing, heartbeat and digestion
What and where is the CEREBELLUM responsible?
Walnut shaped area responsible for receiving info from the Pons
It coordinates sequences of body movements
What is the RETICULAR FORMATION responsible and where is it?
Mostly situated in mid brain it partly falls into the hindbrain
Involved in the sleep wake cycle
Where is the CEREBRUM and what is it involved in?
Largest part of the brain and responsible for higher order thinking
What is the AMYGDALA?
It is an almond Shaped structure located in the medial temporal lobe and is involved in learning and forming emotional memories and responses
What is the HIPPOCAMPUS?
A finger sized curved structure located in the medial temporal lobe involved in memory particularly long term memory
What is the HYPOTHALAMUS and what is it’s role?
It a small structure involved in survival actions
Sleep, regulation of body temp, expression of emotions and the 4 f’s (fight feed flee and fornication)
What is the THALAMUS and what does it do?
Located beneath the cerebral cortex and is divided into two egg shaped parts one in each hemisphere.
It receives info from ears, eyes, skin and other sensory organs (not nose)
Overall it regulates activity in the cortex
What is CONTRALATERAL ORGANISATION?
It is the term used to describe how the right side of the brain controls the left side of the body and the left side of the brain controls the right side of the body.
What is the role of the CEREBRAL CORTEX?
It is the outer layer of the forebrain and is responsible for receiving info from the environment and controls out responses
Involved in higher order thinking including planning and solving problems
Also involved in memory, language and regulation of emotions
What are the lobes of the cerebral cortex?
Frontal, parietal, temporal and occipital
What are the PRIMARY CORTICES?
They are the primary visual cortex, primary auditory cortex, primary somatosensory cortex and primary motor cortex
What is the responsibility of the FRONTAL lobe?
It is the largest of the four lobes and is involved in initiating movement, language, planning, judgement, problem solving, aspects of personality, regulation of emotions.
What is the role of the PARIETAL lobe?
Most of the parietal lobe is take up by the somatosensory cortex.
It’s role is to Receive sensations e.g touch, pressure, temp and body pain
What is the role of the TEMPORAL lobe?
It processes auditory info. The primary auditory cortex is located in the upper part of the temporal lobe.
What is the role of the OCCIPITAL lobe?
It is entirely concerned with vision. It receives info from the retina. Info from the LVF is processed on the right side of the brain vice versa.
What is HEMISPHERIC SPECIALISATION?
Where the two hemispheres work together while at the same time having their own specialisations. Connecting through the corpus callosum.
