|---|---|---|---|---|---|
| What is the largest part of the brain and what does it do? | show 🗑
|
||||
| show | The cerebrum is divided into two hemispheres (Left and Right). Bridging the gap is a bundle of fibres called the corpus callosum. Covering the outermost layer of the cerebrum is the cerebral cortext.
🗑
|
||||
| show | Frontal Lobe, Parietal lobe, Occipital lobe, Temporal Lobe (Including Amygdala and Hippocampus) , Basal Ganglia, Thalamus and Hypothalamus
🗑
|
||||
| show | Initiating and co-ordinating motor movements; higher cognitive skills, such as problem solving, thinking, planning, and organising; and for many aspects of personality and emotional makeup
🗑
|
||||
| show | Involved with sensory processes, attention and language
🗑
|
||||
| What is the occipital lobe responsible for? | show 🗑
|
||||
| show | Helps process auditory information and puts information together from the other sensors. It is also thought to have a role in short term memory and in learned emotional responses through its amygdala
🗑
|
||||
| show | Cerebral nuclei deep in the cerebral cortex. They help co-ordinate muscle movements and reward useful behaviours
🗑
|
||||
| What does the thalamus do? | show 🗑
|
||||
| What does the hypothalamus do? | show 🗑
|
||||
| show | Consists of two pairs of small hills called colliculi. These collections of neurons play a big role in visual and auditory reflexes. It also has clusters of neurons that regulate activity in widespread parts of the CNS. Good for reward mechs and mood
🗑
|
||||
| What does the hindbrain consist of? | show 🗑
|
||||
| What do the pons and medulla oblongata do? | show 🗑
|
||||
| Describe the cerebellum | show 🗑
|
||||
| show | Receives sensory information from all parts of the body below the head. It uses this information for reflexes and also relays the info to the brain. It also generates nerve impulses in nerves that control muscles and the viscera. (reflex and voluntary)
🗑
|
||||
| show | The forebrain, midbrain, hindbrain and the spinal cord
🗑
|
||||
| show | The brain is protected by the skull and the spinal cord is protected by the vertebral column
🗑
|
||||
| show | Nerves and concentration of gray matter caled ganglia. It is divided into the somatic nervous system and the autonomic nervous system
🗑
|
||||
| How does the somatic nervous system work? | show 🗑
|
||||
| show | Made up of neurons connecting the CNS with internal organs. 2 parts - The sympathetic nervous system mobilises energy and resources during time of stress and arousal. The parasympathetic nervous system conserves energy and resources during relaxed states
🗑
|
||||
| How are messages carried throught the nervous system? | show 🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
