All are attached to coracoid process, except?
**Core Concept**
The coracoid process is a small hook-like structure on the scapula that serves as an attachment point for several muscles and ligaments. It plays a crucial role in the musculoskeletal anatomy of the shoulder girdle. The **coracoid process** provides attachment to the **coracobrachialis**, **short head of the biceps**, and **pectoralis minor** muscles.
**Why the Correct Answer is Right**
The correct answer is the one that is not attached to the coracoid process. The **coracobrachialis**, **short head of the biceps**, and **pectoralis minor** are all attached to the coracoid process, whereas the **long head of the biceps** is attached to the supraglenoid tubercle of the scapula.
**Why Each Wrong Option is Incorrect**
**Option A:** The coracobrachialis is attached to the coracoid process, making it an incorrect answer.
**Option B:** The short head of the biceps is also attached to the coracoid process.
**Option C:** The pectoralis minor is attached to the coracoid process.
**Clinical Pearl / High-Yield Fact**
The muscles attached to the coracoid process are important for movements of the shoulder joint, including flexion, adduction, and rotation.
**Correct Answer:** D. Long head of biceps.
