Mg can be treated by increasing the amount of ach reaching the receptor to overcome the blockade and by controlling the immune response. ...Read more

Please help! what is the role of pituitary gland in causing bitemporal hemianopia?

Pituitary tumors: Hi. the optic chiasm (optic nerves; some of them cross sides) is right above the pituitary. Big pituitary tumors can push up out of the pituitary's bony pocket (the sella) and push against the parts of the optic nerves that cross (they see lateral/temporal visual fields) and cause bitemporal hemianopsia; the parts of the optic nerves that see the medial visual fields are spared. ...Read more

What is the pathology that causes myasthenia gravis?

Autoantibodies...: Myasthenia gravis is characterized by weakness / fatigue of muscles under voluntary control. It is caused by abnormal communication between nerves and muscles. In mg, the immune system makes autoantibodies that block or destroy many of a muscles' receptor sites for a neurotransmitter called acetylcholine.
