The Physical Exam: 11 Key Components & Why They Matter

A thorough physical exam is the cornerstone of clinical diagnosis. Here’s what a clinician systematically evaluates:

1. Inspection – General appearance, skin, posture, gait, distress signs.
2. Palpation – Temperature, texture, tenderness, masses, organomegaly.
3. Percussion – Resonance vs. dullness over lungs, abdomen, heart borders.
4. Auscultation – Heart (murmurs, gallops), lungs (wheezes, crackles), bowel sounds, bruits.
5. Neurological – Mental status, cranial nerves, motor/sensory, reflexes, coordination, gait.
6. Cardiovascular – Pulse, BP, JVP, heart sounds, edema.
7. Respiratory – Rate, effort, percussion, auscultation, SpO₂.
8. Gastrointestinal – Inspection, auscultation, palpation (light/deep), liver/spleen span.
9. Musculoskeletal – ROM, strength, joint stability, deformities.
10. Integumentary – Lesions, rashes, nails, hair, mucosa.
11. Genitourinary – External exam (male: testes, prostate via DRE; female: pelvic exam if indicated).

Why It Matters

• Detects asymptomatic disease (HTN, murmurs, masses).
• Monitors chronic conditions.
• Guides targeted testing—avoids shotgun imaging/labs.
• Builds therapeutic relationship.

Annual exams are recommended for adults; frequency tailored to age, risk, and comorbidities.
