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
