Mnemonic for remembering muscle bands and their components
I found it very difficult during my usmle prep to remember
the components of various bands in a muscle fiber. Even after multiple reads
and memorization I still could not recall it. All that changed when I came up
with a simple mnemonic .
I = I band
I act at 5am hence my sleepiness
I = I band
act = actin
at = A band
5 am = actin + myosin
hence = H zone
my sleepiness = myosin

Preparing for exams involving Biochemistry and Genetics can be tough as plethora of facts needs to be committed to memory. This is especially true when you are preparing for your USMLE Step 1 exam. Hopefully, the following visual mnemonic will help ease down your memorization process for remembering major Autosomal dominant diseases.
If you commit this statement listed below in your mind with the image to help you guide through, you will never have a hard time recalling the major Autosomal dominant diseases:
Osler Family is Hyper because Mary Huntington Von Turbo Sphereing MEN Across Hill.
- Osler-Weber-Rendu syndrome (Osler)
- Familial hypercholesterolemia (Family Hyper)
- Marfan's syndrome (Mary)
- Huntington's disease (Huntington)
- Von Recklinghausen's Disease (Von)
- von Hippel-Lindau disease (Von)
- Tuberous sclerosis (Turbo)
- Hereditary spherocytosis (Sphereing)
- Multiple endocrine neoplasias (MEN)
- Achondroplasia (Across)
- Hypokalemic periodic paralysis (Hill)
- Autosomal dominant polycystic kidney disease (ADPKD)
The picture shows a young Mary Huntington sphereing a globe full of MEN across a hill and she appears to be winning or probably have just won (Von), which makes the Osler Family very mad and hyper. Also note that the whole sphereing event is hosted by the ADPKD foundation.
By the way, sphereing or zorbing is a recreational activity/sport of rolling a transparent plastic spherical orb with passenger(s) down the hill.
Mnemonic for innervation of baroreceptors
Many at times students come across questions in USMLE regarding baroreceptors, their location and their innervation. At times questions focus on the loss of innervation and its resultant effects on the body and its very critical to remember which baroreceptors are innervated by which nerves.
Arterial baroreceptors are located in the aortic arch and the carotid sinuses of the right and left carotid arteries. The baroreceptors found within the aortic arch monitor the pressure of blood delivered to the systemic circuit, and the baroreceptors within the carotid arteries monitor the pressure of the blood being delivered to the brain.
The glossopharyngeal nerves transmits impulses from carotid sinuses whilst the vagus nerves transmits impulses from the aortic arch. A simple mnemonic to remember this is:
