What is the origin of the long head of the biceps?
The long head of the biceps brachii (LHB) tendon arises from the supraglenoid tubercle in the shoulder joint, passes through the IS, and joins with the short head. The LHB attaches to the superior glenoid labrum and the neck of the scapula in the shoulder joint.
What is the origin and insertion for the biceps brachii long head?
The biceps muscle has two heads, the short head and the long head, distinguished according to their origin at the coracoid process and supraglenoid tubercle of the scapula, respectively. The short head inserts distally on the tuberosity while the long head inserts proximally closer to the apex of the tuberosity.
Where does the biceps brachii originate from?
Origin. The biceps brachii consists of two heads and they both originate from the scapula. Short Head: Apex of the coracoid process of the scapula.
Where does the long head of the biceps brachii attach?
supraglenoid tubercle of
Both heads originate on the scapula, which is the technical name for the shoulder blade. The long head attaches to the supraglenoid tubercle of the scapula, which is just above the space where the humerus, or upper arm, enters the shoulder. The short head attaches to the coracoid process of the scapula.

What is the origin of the Brachialis?
The brachialis originates from the anterior surface of the distal half of the humerus, near the insertion of the deltoid muscle, which it embraces by two angular processes. Its origin extends below to within 2.5 cm of the margin of the articular surface of the humerus at the elbow joint.
What is the triceps brachii long head?
The long head of the Triceps brachii is one of three heads that make up the muscle. It descends between teres minor and major, dividing the wedge-shaped interval between them and the humerus into triangular and quadrangular spaces.
