No matter where you are up to in your training, anatomical terminology is the foundation of precise communication in medicine.
Instead of saying “towards the head” or “away from the body”, clinicians use standardised terms that mean the same thing to everyone — in any hospital, clinic, or country.
This shared language eliminates ambiguity and reduces the risk of miscommunication.
📌 Key Terms Every Med Student Must Know:
🔹 Planes of the body
These describe how the body is divided for description, imaging, and anatomy:
- Sagittal plane – divides the body into left and right
- Coronal (frontal) plane – divides the body into anterior (front) and posterior (back)
- Transverse plane – divides the body into superior (upper) and inferior (lower) parts
🔹 Directional terms
These describe where one structure is relative to another:
- Superior / Inferior – towards the head / towards the feet
- Anterior (ventral) / Posterior (dorsal) – front / back
- Medial / Lateral – towards the midline / away from the midline
- Proximal / Distal – closer to / further from the trunk (especially important for limbs)
These terms are always used with the body in the standard anatomical position, regardless of how the patient is actually lying or sitting.
💡 Why does this matter?
Imagine describing the location of an injury, tumour, or surgical incision without a shared reference system.
Clear anatomical language:
- Reduces misunderstanding
- Improves handover and documentation
- Supports safe, efficient patient care
This is why these terms appear everywhere — from anatomy labs to radiology reports and operation notes.
🔍 Question for you:
Instead of pointing or gesturing, clinicians describe locations precisely and reproducibly.
Think fast — how would you describe the location of:
👉 The back of the knee?
👉 The thumb compared to the little finger?
👉 The wrist compared to the elbow?
Use proper anatomical terms only — no pointing allowed.
(You’ll be surprised how quickly this becomes second nature.)
