Biceps Brachii Anatomy Quiz

1. The biceps brachii muscle is located in the posterior compartment of the arm.

a. True

b. False

The answer is b, false. The biceps brachii is located in the anterior compartment of the arm.

2. How many heads does the biceps brachii typically have?

a. Four

b. Two

c. Three

d. One

The answer is b, two. Although some individuals can have more than two heads, the word “biceps” literally means two heads, and that is the typical number found.

3. Where does the short head of the biceps brachii originate?

a. Radial tuberosity

b. Supraglenoid tubercle of scapula

c. Coracoid process of scapula

d. Humerus bone

The answer is c, coracoid process of the scapula. To remember this, think short cake (short = coracoid).

4. Where does the long head of the biceps brachii originate?

a. Radial tuberosity

b. Supraglenoid tubercle of scapula

c. Coracoid process of scapula

d. Humerus bone

The answer is b, the supraglenoid tubercle of the scapula bone. This tendon runs down through the intertubercular groove of the humerus, but does not attach to the humerus bone.

5. Where does the biceps brachii muscle insert?

a. Radial tuberosity

b. Supraglenoid tubercle of scapula

c. Coracoid process of scapula

d. Humerus bone

The answer is a, the radial tuberosity of the radius. There is also a bicipital aponeurosis, which joins the connective tissue at the cubital fossa.

6. A major function (or action) of the biceps brachii is to bring the forearm closer to the arm (elbow flexion).

a. True

b. False

The answer is a, true. That’s why curling exercises, which flex the elbow, help develop the biceps brachii muscle.

7. The biceps brachii also supinates the forearm and assists in arm flexion.

a. True

b. False

The answer is a, true. The biceps brachii helps supinate the forearm, which is why some bodybuilders like to supinate the weight as they curl. It also assists with arm flexion.

    Muscles in the Anterior Compartment of the Forearm

    There are many muscles in the forearm. In the anterior compartment, they are split into three categories: superficial, intermediate and deep.

    In general, muscles in the anterior compartment of the forearm perform flexion at the wrist and fingers, and pronation.


    Superficial Compartment

    The superficial muscles in the anterior compartment are the flexor carpi ulnaris, palmaris longus, flexor carpi radialis and pronator teres. They all originate from a common tendon, which arises from the medial epicondyle of the humerus.

    Flexor Carpi Ulnaris

    • Attachments:  Originates from the medial epicondyle with the other superficial flexors. It also has a long origin from the ulna. It passes into the wrist and attaches to the pisiform carpal bone.
    • Actions: Flexion and adduction at the wrist.
    • Innervation:Ulnar nerve.

    Palmaris Longus

    This muscle is absent in about 15% of the population.

    Dissection Tip: Just distal to the wrist, if you reflect back the palmaris longus, you will find the median nerve immediately underneath it

    • Attachments:  Originates from the medial epicondyle, attaches to the flexor retinaculum of the wrist.
    • Actions: Flexion at the wrist.
    • Innervation:Median nerve.

    Flexor Carpi Radialis

    • Attachments: Originates from the medial epicondyle, attaches to the base of metacarpals II and III.
    • Actions: Flexion and abduction at the wrist.
    • Innervation: Median nerve.

    Pronator Teres

    The lateral border of the pronator teres forms the medial border of the cubital fossa, an anatomical triangle located over the elbow.

    • Attachments: It has two origins, one from the medial epicondyle, and the other from the coronoid process of the ulna. It attaches laterally to the mid-shaft of the radius.
    • Actions: Pronation of the forearm.
    • InnervationMedian nerve.
    [caption id="attachment_" align="aligncenter" width=""]Fig 1 - The superficial muscles of the anterior forearm.[/caption]

    Intermediate Compartment

    The flexor digitorum superficialis is the only muscle of the intermediate compartment. It can sometimes be classed as a superficial muscle, but in most individuals, it lies between the deep and superficial muscle layers.

    The muscle is a good anatomical landmark in the forearm - the median nerve and ulnar artery pass between its two heads, and then travel posteriorly.

    • Attachments: It has two heads - one originates from the medial epicondyle of the humerus, the other from the radius. The muscle splits into four tendons at the wrist, which travel through the carpal tunnel, and attaches to the middle phalanges of the four fingers.
    • Actions: Flexes the metacarpophalangeal joints and proximal interphalangeal joints at the 4 fingers, and flexes at the wrist.
    • Innervation: Median nerve.

    Deep Compartment

    There are three muscles in the deep anterior forearm: flexor digitorum profundus, flexor pollicis longus, and pronator quadratus.

    Flexor Digitorum Profundus

    • Attachments: Originates from the ulna and associated interosseous membrane. At the wrist, it splits into four tendons, that pass through the carpal tunnel and attach to the distal phalanges of the four fingers.
    • Actions: It is the only muscle that can flex the distal interphalangeal joints of the fingers. It also flexes at metacarpophalangeal joints and at the wrist.
    • Innervation: The medial half (acts on the little and ring fingers) is innervated by the ulnar nerve. The lateral half (acts on the middle and index fingers) is innervated by the anterior interosseous branch of the median nerve.

    Flexor Pollicis Longus

    This muscle lies laterally to the FDP.

    • Attachments: Originates from the anterior surface of the radius and surrounding interosseous membrane. Attaches to the base of the distal phalanx of the thumb.
    • Actions:  Flexes the interphalangeal joint and metacarpophalangeal joint of the thumb.
    • Innervation: Median nerve (anterior interosseous branch).

    Pronator Quadratus

    A square shaped muscle found deep to the tendons of the FDP and FPL.

    • Attachments: Originates from the anterior surface of the ulna and attaches to the anterior surface of the radius.
    • Actions: Pronates the forearm.
    • Innervation: Median nerve (anterior interosseous branch).
