@RUSM_PM The abductor hallucis is located medially along the foot, extending from the hind foot to the midfoot. The abductor hallucis functions in flexion and motion away from the midline of the great toe. #RUSMPMX

@RUSM_PM The endoplasmic reticulum is a series of cisternae which are adjacent to the nucleus and are responsible for protein synthesis (via ribosomes through the rough ER) and lipid synthesis (via non-ribosome studded portions of the smooth ER). #RUSMPMX

@RUSM_PM Competitive inhibition of enzymes is when an inhibitor competes for the active site of an enzyme, preventing the substrate from binding which prevents the reaction of the enzyme from happening. #RUSMPMX

@RUSM_PM Prothrombin Time is a blood test used in finding how long it takes for blood to clot, often times used in diagnosis of different bleeding ailments. #RUSMPMX

@RUSM_PM Hybridization probe is a fragment of genetic material with a marker, either DNA or RNA, which binds to a complimentary sequence onto a specific strand of DNA/RNA and allows for visualization of specific sequences.

@RUSM_PM Flexor digiti minimi brevis is a muscle located on the fifth digit of the feet and hands which causes flexion of the digit at the MP joint. #RUSMPMX

@RUSM_PM The urea cycle is the process by which ammonia (often from the degradation of protein) undergoes a series of biochemical reactions to become urea for safe removal. #RUSMPMX

@RUSM_PM Trisomy is an aneuploidy in which there are three copies of the same chromosome, often caused by a sex cell undergoing non-disjunction and matching with a normal sex cell. #RUSMPMX

@RUSM_PM Mast cells are white blood cells which contain histamine and heparin granules. Mast cells roles are immunological in nature throughout the body and the brain. They are responsible for initiation of inflammatory pathways. #RUSMPMX

@RUSM_PM The great saphenous vein is the longest vein in the body located in the lower limbs with many tributary veins connected to it. Beyond being a connection site, the vein is often used for bypass operations. #RUSMPMX

@RUSM_PM The SCM is the muscle which runs along the anterior neck from the manubrium and inserts at the mastoid process. It functions in neck rotation and flexion/extension as well as respiration. Clinically, it can be used as an anatomical landmark for the carotid artery. #RUSMPMX

@RUSM_PM Autosomal recessive describes alleles which require inheritance of both for expression. A carrier is a subject that possesses one autosomal recessive allele and one autosomal dominant allele. #RUSMPMX

[Matthew Bellesheim @Matt_Bellesheim]

@RUSM_PM Mendelian inheritance pattern describes the branch of genetics involving a single gene alteration during inheritance. A disease which falls under this category is cystic fibrosis. #RUSMPMX

@RUSM_PM The suboccipital triangle is the name for the region at the skull/C-spine junction which contains the rectus capitis posterior major, the obliquus capitis superior, and the obliquus capitis inferior. Together this provides us with finer motions of the head. #RUSMPMX

@RUSM_PM Reciprocal Translocation is a form of chromosomal translocation where a portion of two non-homologous chromosomes are exchanged. #RUSMPMX
