Dr. Ebraheim’s educational animated video describes the muscle anatomy on the palm of the hand. The muscles of the hand are divided into three groups: 1-Thenar group: near the thumb 2-Hypthenar group: near the little finger 3-Muscles in the middle of the palm and between the metacarpal bone The thenar and hypothenar muscles are a mirror image of each other. The thumb is very mobile, therefore, the thenar muscles are very important. The two abductor muscles function as abductors. the two opponens muscles are deep and they function to oppose against the other fingers. Out of the two flexors, the flexor pollicis brevis is unique because of its dual nerve supply. Hypothenar group: •Abductor digiti minimi: arises from the pisiform bone, the pisohamate ligament and the flexor retinaculum. It is inserted into the medial side of the base of the proximal phalanx. It is an abductor of the little finger at the metacarpophalangeal joint. •Flexor digiti minimi: arises from the hook of the hamate bone as well as the flexor retinaculum and is inserted into the medial side of the base of the first phalanx of the little finger. The flexor digiti minimi flexes the proximal phalanx of the little finger. •Opponens digit minimi: arises from the hook of the hamate and the flexor retinaculum. It is inserted into the entire length of the metcarpal bone of the little finger. The opponens digiti minimi opposes the little finger. Thenar group •Abductor pollicis brevis: originates from the flexor retinaculum and the tubercle of the scaphoid bone. It is inserted into the lateral side of the base of the first phalanx of the thumb. The abductor pollici brevis is responsible for abduction of the thumb. •Flexor pollicis brevis: arises from the flexor retinaculum and the tubercle of the trapezium bone. It is inserted into the lateral side of the base of the proximal phalanx of the thumb. The flexor pollici brevis flexes the thumb at the metacarpophalangeal joint. The flexor pollici brevis has both superficial part and a deep part. •Opponens pollicis: opponens pollicis originates from the flexor retinaculum of the hand and the tubercle of the trapezium and it is inserted into the entire length of the metacarpal bone of the thumb. The opponens pollicis is a deep muscle and it opposes the thumb against the other fingers. Innervation •Hypothenar group is innervated by the deep branch of the ulnar nerve. •The thenar group is innervated by the recurrent branch of the median nerve. The ddep part of the flexor pollicis brevis is usually innervated by the deep branch of the ulnar nerve. Blood supply •The flexor pollicis brevis and the opponens pollicis receive their blood supply from the superficial palmar arch.

This is a preview of the 'thenar muscles of the hand' video tutorial, which discusses the origin, insertion, function and innervation of the muscles of the thenar eminence. Take a closer look in our atlas: https://khub.me/d42dg Oh, are you struggling with learning anatomy? We created the ★ Ultimate Anatomy Study Guide ★ to help you kick some gluteus maximus in any topic. Completely free. Download yours today: https://khub.me/gtlvs The thenar musculature consists of four muscles: - the abductor pollicis brevis, - the adductor pollicis, - the flexor pollicis brevis, and - the opponens pollicis. Located on the radial side of the palm, they form together the 'ball' of the thumb known as the thenar eminence. They originate at different carpal bones and distally attach to the thumb. Innervated by the median and/or ulnar nerves, those muscles are responsible for moving the thumb in several directions, allowing you to show someone 'thumbs up' for a job well done. The full version of this video tutorial examines the thenar muscles of the hand in detail, looking at the origins, insertions, innervation and functions of those important anatomical structures of the hand.

Dr. Ebraheim’s educational animated video describes the anatomy of the opponens pollicis muscle. The opponens pollicis is part of the thenar eminence. It is one of three thenar muscles: opponens pollicis, abductor pollicis brevis, and flexor pollicis brevis. The opponens pollicis originated from the flexor retinaculum and the tubercle of the trapezium. The opponens pollicis is inserted into the metacarpal bone of the thumb on its radial side. It is innervated by the recurrent branch of the median nerve. Flexion of the thumb’s metacarpal at the first carpometacarpal joint, which aids in opposition of the thumb. Ask the patient to touch the thumb and small finger tops together so that the nails are parallel. Try to feel the opponens pollicis muscle. Ask the patient to place the dorsum of the hand flat on the table. Ask the patient to raise the thumb up straight to form a 90 degree angle with the palm then palpate the contracting thenar muscles.
