Neurology and Medical Imaging

Study Notes

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.

Neurological Disorders

Amyotrophic Lateral Sclerosis (ALS) is a progressive disorder characterized by the degeneration of nerve cells in the brain and spinal cord, also known as Motor Neuron Disease (MND).

Medical Imaging

Positron Emission Tomography (PET) is a medical imaging technique that uses radiotracers to evaluate body functions such as blood flow, oxygen use, and sugar metabolism.

Anatomy

Pectoralis major forms the anterior border of the axilla.
The lacrimal gland is responsible for producing tears to keep the eye moist.

Endocrinology

Cortisol is a hormone produced by the adrenal glands that helps the body respond to stress.

Sensory Systems

The vestibular system in the inner ear helps maintain balance and spatial orientation.
The oculomotor nerve (cranial nerve III) is responsible for controlling eye movements.
The hypothalamus plays a crucial role in regulating body temperature and hunger.

Molecular Biology

Messenger RNA (mRNA) is a type of RNA that carries genetic information from DNA to the ribosome for protein synthesis.

Graphic Design and Printing
