Best anatomy notes of upper limb
Here we are discussing about best anatomy notes of upper limb, includes muscles, nerves, arteries, brachial plexus,cubital fossa..
Important anatomy topics of upper limb
- 1.Muscles and their nerve supply
- 2.Brachial plexus & deformities
- 3.Axillary artery
- 4.Palmar arches
- 5.Cubital fossa
- 6.Carpal tunnel
- 7.Major nerve injuries
Best anatomy notes of upper limb
| no | important anatomy notes of upper limb |
|---|---|
| 1 | Largest carpal bone-Capitate bone |
| 2 | “Dynamic stabilizer of shoulder joint” is another name of Rotator cuff. |
| 3 | Wrist joint is an ellipsoid joint. |
| 4 | Klumpke’s paralysis involves C8 and Tl |
| 5 | Erb’s point is at the junction of C5, C6 |
| 6 | Another name of Median nerve is “laborer’s nerve” |
| 7 | Froment’s sign is characteristically seen in Ulnar nerve injury |
| 8 | Claw hand is caused by lesion of the Ulnar nerve. |
| 9 | “Guyon’s canal” is in relation to the Ulnar nerve |
| 10 | Wrist drop is due to injury of Radial nerve |
| 11 | Carpel tunnel syndrome is due to compression of the Median nerve. |
| 12 | Winging of scapula is due to paralysis of Serratus anterior |
| 13 | Radial Artery is one of the content of anatomical snuffbox |
| 14 | Upper lateral cutaneous nerve of arm – axillary nerve |
| 15 | Lower lateral cutaneous nerve of arm – radial nerve |
| 16 | Posterior cutaneous nerve of arm – radial nerve |
| 17 | Posterior cutaneous nerve of forearm – radial nerve |
| 18 | Medial cutaneous nerve of arm – medial cord |
| 19 | Medial cutaneous nerve of forearm – medial cord |
| 20 | Lateral cutaneous nerve of forearm – Musculo cutaneous nerve |
| 21 | pulsations of radial artery can be felt in the anatomical box |
| 22 | tenderness in the anatomical box indicates fracture of scaphoid bone |
| 24 | Klumpke’s Paralysis or Klumpke Dejerine is the Paralysis Involves lower trunk of brachial plexus – C8 & T1 |
| 25 | Axillary tail (tail of Spence) is a superolateral extension of the mammary gland. |
| 26 | The weight of the upper limb is transmitted to the axial skeleton by the coracoclavicular ligament |
| 27 | Anatomically a muscle of upper limb, but functionally related to the trunk is the Latissimus dorsi. |
| 28 | The muscle that crosses both the shoulder and elbow joint is Biceps brachii |
| 29 | Biceps brachii is supplied by Musculocutaneous nerve |
| 30 | Serratus anterior muscle helps in forced inspiration. |
| 31 | Teres major muscle is supplied by the Lower subscapular nerve. |
| 32 | Anatomically a muscle of upper limb, but functionally related to the trunk is the Latissimus dorsi. |
| 33 | Scaphoid – Boat shaped Trapezium – Quadrangular Lunate – Halfmoon shaped Trapezoid – Baby shoe shaped Triquetral – Pyramidal shaped Capitate – Largest carpal bone Pisiform – Pea shaped Hamate – Wedge shaped |
| 34 | Fracture of 1st metacarpal is called ‘Bennett’s fracture. |
| 35 | Dorsal tubercle of the radius called Lister’s tubercle |
| 36 | Smith’s fracture results from a fall or a blow on the dorsal aspect of the flexed wrist and produces a ventral angulation of the wrist. The distal fragment of the radius is ANTERIORLY displaced. |
| 37 | Colles’ fracture results from forced extension of the hand, usually as a result of trying to ease a fall by outstretching the upper limb. Distal fragment is displaced DORSALLY – “dinner fork deformity”. |
| 38 | Boxers fracture-Necks of the metacarpal bones are frequently fractured during fistfights.Typically, fractured 2d and 3d metacarpals |
| 39 | Palmaris longus passes superficial to the flexor retinaculum. |
| 40 | Most of the blood to the head and neck of the femur is supplied by the medial circumflex femoral artery |
| 41 | Sesamoid is present in the tendon of flexor hallucis brevis |
| 42 | Lunate dislocation is most common in falls on the out-stretched hand, compressing the median nerve within the carpal tunnel and producing carpal tunnel syndrome. |
| 43 | Ape hand deformity is due to Median nerve injury |
| 44 | Nerve that causes extension of the thumb – Radial nerve |
| 45 | Nerve which adducts the thumb – Ulnar nerve |
| 46 | The Corachobrachialis is pierced by – Musculocutaneous nerve |
| 47 | The flexor carpi ulnaris is pierced by – Ulnar nerve |
| 48 | The deep branch of the radial nerve pierces – Supinator muscle |
| 49 | Serratus anterior is a protractor of scapula. It also causes lateral rotation of scapula along with trapezius and both muscles are involved in overhead abduction |
