Covers corticospinal, cerebellar, and basal ganglia control, pegboard normative scores, developmental milestones, and stroke rehabilitation robotics.
Fine-needle aspiration
Fine-needle aspiration (FNA, FNAC): minimally invasive biopsy using a thin (22-gauge or smaller) needle to sample cells from a mass for microscopic diagnosis; pioneered at Memorial Hospital in the 1920s-1930s and revived by the Swedish Karolinska school.
FINEARTS-HF trial
FINEARTS-HF (NCT04435626): Bayer-funded randomized trial of finerenone, a nonsteroidal MRA, in 6,001 patients with heart failure and LVEF ≥40%; reduced total worsening HF events and CV death (RR 0.84).
Finerenone
Finerenone (Kerendia), a nonsteroidal mineralocorticoid receptor antagonist approved in 2021 for diabetic CKD and in July 2025 for heart failure with LVEF ≥40%, based on FIDELIO-DKD, FIGARO-DKD, and FINEARTS-HF trials.
Finger
Finger: one of five human hand digits, each with three phalanges (two in the thumb), moved by tendons and ligaments. Hox and SHH patterning constrains tetrapods to at most five true digits.
Finger stick
A finger stick is a minimally invasive procedure that pricks a fingertip with a lancet to obtain capillary blood for testing, especially glucose monitoring in diabetes.
Finger tapping test
The finger tapping test (FTT), also called the finger oscillation test, is a neuropsychological assessment measuring psychomotor speed by counting index-finger taps in 10-second trials.
FINGER trial
FINGER (Finnish Geriatric Intervention Study to Prevent Cognitive Impairment and Disability) is a 2015 randomized controlled trial of 1,260 at-risk older adults showing a 2-year multidomain lifestyle intervention improved cognition, spawning the World-Wide FINGERS network.
Fingerprint
Fingerprint: impression of friction ridges on fingers, formed in fetal development, unique and lifelong. Used for identification since ancient China; modern forensics (Galton, Henry, AFIS) and biometrics with measured error rates.
Fingerprint body myopathy
Fingerprint body myopathy (OMIM 305550, ORPHA:97232) is a rare congenital myopathy with neonatal hypotonia, weakness, and fingerprint-pattern lamellar inclusions seen only on electron microscopy; under 20 patients reported.
Fingerstick
A fingerstick is a minimally invasive blood sampling method in which a lancet pricks the fingertip for a small drop of capillary blood, most often for glucose testing.
Fingolimod
Fingolimod (FTY720), sold as Gilenya, is an oral sphingosine 1-phosphate receptor modulator for relapsing multiple sclerosis, approved by the FDA in 2010 as the first oral MS therapy.
Finkelstein's test
Finkelstein's test, a wrist physical-exam maneuver for de Quervain's tenosynovitis, also called Finkelstein sign: thumb held in palm, ulnar deviation, pain at radial styloid; more specific than the commonly confused Eichhoff test.

Firibastat
Firibastat (RB150, QGC001) is an oral brain aminopeptidase A inhibitor prodrug of EC33 developed by Quantum Genomics for hypertension; phase 3 FRESH missed its endpoint and development stopped in 2022.

First aid
First aid is the immediate initial care given at the scene of an injury or sudden illness, with three goals: preserve life, prevent deterioration, and promote recovery.
First aid kit
First aid kit: a packaged collection of supplies for emergency initial treatment. Regulated via OSHA 1910.151 and ANSI Z308.1 Class A/B kits in the US, BS 8599 in the UK, CSA Z1220 in Canada.

A first branchial cleft anomaly is a rare congenital malformation in which incomplete closure of the first branchial cleft leaves a cyst, sinus, or fistula near the ear.
First degree haemorrhoids
First degree haemorrhoids (grade I, ICD-11 DB60.0) are internal haemorrhoids that bulge into the anal canal and bleed but do not prolapse; treated first with fiber, fluids, and bowel-habit counseling, then office banding if refractory.

The first pass effect, or first-pass metabolism, is the metabolism of an oral drug in the liver and intestinal wall before it reaches systemic circulation, reducing bioavailability.
