💪 Cubital Fossa (Elbow Region)

Let’s understand this in a very simple way.

What is cubital fossa?
It is a triangular depression in front of the elbow. This is the area where we often take blood samples or check pulse.

What forms its boundaries?
The cubital fossa has important muscular boundaries.

✅ Correct Answer: (c) Brachioradialis

Why brachioradialis?
The lateral (outer) boundary of the cubital fossa is formed by the brachioradialis muscle.

👉 So, it is one of the key muscles forming the cubital fossa.

Quick boundaries for easy recall:

• Lateral → Brachioradialis
• Medial → Pronator teres
• Superior → Line between epicondyles

Why other options are not correct?

• (a) Biceps → ❌ Forms roof/content (tendon), not main boundary
• (b) Triceps → ❌ Located posterior to arm
• (d) Coracobrachialis → ❌ Located in upper arm, not cubital fossa

Simple Exam Trick:
Cubital fossa → Outer side → Brachioradialis

📌 Note: Cubital fossa is clinically important for venipuncture and blood pressure measurement.
