The Brain and Brain and spinal cord problems
Karten in diesem Stapel (12)
- 1Describe the function and explain how a CT works.A CT scan uses X-ray detectors and builds an image to show the surgeon the shape and structure of the brain by measuring the absorption of the X-Rays. The computer can use this information to give images of different slices.
- 2Describe the function and explain how a PET works.A PET scan shows the activity of areas of the brain or the brain as a whole.
In a PET scan, the patient must digest radioactive glucose. This glucose is taken into more active cells, and as the glucose emits gamma rays the scanner can detect them and build an image. - 3How is brain function studied and measured? Advantages?Using A CT scanner the shape and structure of the brain are detected and any tumours will be found.
On the other hand, a PET scan shows the activity of the parts of the brain. This can detect sensory and processing issues in the brain. - 4What could damage to parts of the brain cause?The damage that originates from a brain tumour could be parts of the brain not working as they were squashed by an expanding tumour.
- 5What could damage to parts of the Spinal Cord cause?Damage to the spinal cord results in information not being able to travel from the brain to the rest of the body resulting in loss of feeling and/or movement. The further up the spinal cord the damage is the less control. (Damage to the neck could lead to Quadriplegia loss of feeling in all limbs)
- 6How and why is brain surgery limited?Brain surgery is very risky as every section of the brain is responsible for its own function (smell, hearing, language). As there is no way to differentiate it is very hard for the surgeon to stay away from vital areas and only cut where it is necessary.
- 7What injuries cannot be fully repaired?Injuries such such as neck damage can result in quadriplegia. This is irreversable till now.
- 8Describe what the brain consists ofk
- 9Identify these parts of the brain.1. Cerebellum
2. Cerebral Hemispheres
3. Medula oblongata - 10Describe the function of the CerebellumIt is split into 2 halves
It controls Balance and posture
It coordinates Timing and Fine control of muscle activity
(Musicians have large cerebellums) - 11Describe the function of the Cerebral HemispheresIt is 80% of the brain and has a wrinkled surface for extra surface area separated into 2 halves, each with its slightly different functions.
It controls most of our senses, language, memory, behaviour and consciousness. - 12Describe the function of the Medula oblongataThe Medula Oblongata consists of many nerves. It controls your heart rate and breathing rate along with all reflexes. This connects with the brain and the spinal cord.
