Magnesium | MCQs

Explanation

Magnesium sulfate acts as a muscle relaxant by blocking neuromuscular transmission.

It is used clinically to relieve muscle spasms and prevent seizures in certain conditions.

Explanation

Chlorophyll, the pigment responsible for photosynthesis in plants, features a porphyrin ring structure at its core.

This ring is composed of four smaller pyrrole rings linked by methine bridges.

A magnesium ion is centrally located within this porphyrin ring, held in place by bonds with nitrogen atoms from the pyrrole rings.

Explanation

Magnesium deficiency can contribute to or exacerbate all of the following health issues:

• Painful joints: Magnesium helps regulate inflammation and muscle function, and deficiency can lead to joint pain and stiffness.
• Osteoporosis: Magnesium is essential for bone mineralization and density; deficiency can increase the risk of osteoporosis and fractures.
• Memory loss: Magnesium plays a role in neuronal function and synaptic plasticity; deficiency has been linked to cognitive impairment and memory loss.
• Diabetes: Magnesium helps regulate insulin sensitivity and glucose metabolism; deficiency can increase the risk of developing type 2 diabetes.

Additionally, magnesium deficiency can also lead to other health issues, such as:

• Muscle cramps and weakness
• Fatigue and lethargy
• Cardiovascular problems, including high blood pressure and arrhythmias
• Weakened immune system
• Neurological symptoms, such as anxiety, depression, and seizures
