Neurology and Medical Imaging

Here are the study notes in bullet points:

• Question 1:*
• Amyotrophic Lateral Sclerosis (ALS) is a disorder characterized by progressive degeneration of nerve cells in the brain and spinal cord.
• ALS is also known as Motor Neuron Disease (MND).
• Question 2:*
• Positron Emission Tomography (PET) is a medical imaging technique that uses small amounts of radioactive materials called radiotracers.
• PET scan helps evaluate body functions such as blood flow, oxygen use, and sugar metabolism.
• Question 3:*
• Pectoralis major forms the anterior border of the axilla.
• Question 4:*
• The lacrimal gland is responsible for keeping the eye moist by producing tears.
• Question 5:*
• Cortisol is a hormone produced by the adrenal glands that helps the body respond to stress.
• Question 6:*
• The vestibular system in the inner ear helps maintain balance and special orientation.
• Question 7:*
• The hypothalamus plays a crucial role in regulating body temperature and hunger.
• Question 8:*
• The oculomotor nerve (cranial nerve III) is responsible for controlling eye movements.
• Question 9:*
• Messenger RNA (mRNA) is a type of RNA that carries genetic information from DNA to the ribosome for protein synthesis.
• Question 10:*
• The oculomotor nerve is responsible for controlling eye movements.
• Question 11:*
• In screen printing, a squeegee is used to push ink through a screen onto a substrate.
• Question 12:*
• Fixer is used in the fixing setup in darkroom process to remove unexposed silver halide crystals.
• Question 13:*
• The developer is used in the development setup in darkroom process to make the latent image visible.
• Question 14:*
• A registration mark is used to align different colors or layers in screen printing.
• Question 15:*
• Radioactive isotopes are commonly used in autoradiography in darkroom techniques.
• Question 16:*
• RGB stands for Red, Green, and Blue, which are the primary colors used in screen displays.
• Question 17:*
• Fixer solution is used to remove unexposed silver halide crystals in the film development process.
• Question 18:*
• DPI stands for Dots Per Inch, which is a measurement of the resolution of an image.
• Question 19:*
• Development is the process of converting a latent image on X-ray film into a visible image.
• Question 20:*
• Plastic sol ink requires heat curing to set properly.
