This document contains a series of multiple choice questions about human anatomy from Dr. Upul Udayaraj Jayasinghe. The questions are intended for medical students preparing for exams, but can also help medical professionals refresh essential anatomy basics. The document provides 20 questions about structures like the biceps muscle, brachial plexus, elbow joint, and hand muscles. Each question is followed by feedback explaining the correct answer. The overall document serves as a self-assessment tool for learning important details of human anatomy.

2. Note that the MCQs(Multiple choice questions) on this video
are more suitable for medical students; however, medical
professionals those who are preparing for postgraduate
examinations also can refresh essential basics in anatomy, as
they provide useful knowledge in the relevant subject area in
general. Hence, it is recommended you to go through these
videos and gather some information to gain success in future
medical and surgical field examinations.

C. The short head is attached to the humerus
D. Is inserted to the tuberosity in the medial side of the ulna
E. Is innervated by the ulnar nerve

4. Q 16 - Answer
Select the correct answer;
- The biceps muscle,
A. The short head is attached to the supraglenoid tubercle
B. It has an intra-articular tendon
C. The short head is attached to the humerus
D. Is inserted to the tuberosity in the medial side of the ulna
E. Is innervated by the ulnar nerve

5. Q 16 - Feedback
Correct Answer – B
About Biceps
Origin
- Short head: coracoid process of the scapula
- Long head: supraglenoid tubercle of the scapula
Insertion
- Radial tuberosity and bicipital aponeurosis into deep fascia of the medial side of
the forearm
Nerve
- Musculocutaneous nerve (C5–C7)
Actions
- Flexes elbow
- Flexes and abducts shoulder
- Supinates radioulnar joint in the forearm

6. Q 17
Which option is correct about the brachial plexus?
A. It originates from roots which emerge in front of scalenus
anterior muscle
B. Cords are closely related to the axillary artery
C. Its lateral cord supplies the extensor muscles of the arm
D. The thoracodorsal nerve is a branch of its medial cord
E. Supplies the triceps muscle by its medial cord

7. Q 17 - Answer
Which option is correct about the brachial plexus?
A. It originates from roots which emerge in front of scalenus
anterior muscle
B. Cords are closely related to the axillary artery
C. Its lateral cord supplies the extensor muscles of the arm
D. The thoracodorsal nerve is a branch of its medial cord
E. Supplies the triceps muscle by its medial cord

8. Q 17 - Feedback
Correct Answer – B
The roots of brachial plexus are behind the scalenus anterior
muscle.
All the extensor muscles, including triceps, are supplied by the
posterior code of the brachial plexus.
The thoracodorsal nerve is a branch of posterior cord.

9. Q 18
Please select the correct answer.
- The coracoid process of the scapula gives
attachment to;
A. Pectoralis minor
B. The long head of biceps
C. The long head of triceps
D. Deltoid
E. Pectoralis major

10. Q 18 - Answer
Please select the correct answer.
- The coracoid process of the scapula gives
attachment to;
A. Pectoralis minor
B. The long head of biceps
C. The long head of triceps
D. Deltoid
E. Pectoralis major

11. Q 18 - Feedback
Correct Answer – A
The coracoid process forms a point of attachment to several
muscles, specifically the short head of biceps, the
coracobrachialis, the pectoralis minor; and also the
coracohumeral ligament and transverse scapular ligament.

12. Q 19
Please select the incorrect answer.
- The elbow joint;
A. Is a hinge joint
B. The joint capsule is weak medially and laterally
C. The radial collateral ligament is attached to the annular ligament
D. The synovial membrane is continuous with the proximal radioulnar joint
E. The apex of the triangular ulnar collateral ligament is attached to the
medial epicondyle of the humerus

13. Q 19 - Answer
Please select the incorrect answer.
- The elbow joint;
A. Is a hinge joint
B. The joint capsule is weak medially and laterally
C. The radial collateral ligament is attached to the annular ligament
D. The synovial membrane is continuous with the proximal radioulnar joint
E. The apex of the triangular ulnar collateral ligament is attached to the
medial epicondyle of the humerus

14. Q 19 - Feedback
Correct Answer – B
Elbow joint
A single fibrous capsule encloses the elbow joint and the
superior radioulnar joint.
The capsule is strengthened by ligaments at the sides but
relatively weak in front and behind.

15. Q 20

gives attachment to all the following muscles except:
A. Extensor pollicis brevis
B. Adductor pollicis
C. Abductor pollicis brevis
D. Extensor pollicis brevis
E. Abductor pollicis longus

16. Q 20 - Answer
What is correct?
- The base of the proximal phalanx of the thumb
gives attachment to all the following muscles except:
A. Extensor pollicis brevis
B. Adductor pollicis
C. Abductor pollicis brevis
D. Extensor pollicis brevis
E. Abductor pollicis longus

17. Q 20 - Feedback
Correct Answer – E
Abductor pollicis longus muscle inserts to the base of the first
metacarpal.
