What does the superficial branch of the radial nerve supply in the hand?
The superficial branch of the radial nerve supplies the skin and fascia over the lateral two-thirds of the dorsum of the hand, the dorsum of the thumb, and the proximal parts of the lateral one and a half digits.
Where is the radial pulse rate measured, and what serves as a guide to the artery?
The radial pulse rate is measured on the anterior surface of the distal radius, lateral to the flexor carpi radialis (FCR) tendon, which serves as a guide to the artery.
Where can the tendons of the FCR and palmaris longus be palpated?
The tendons of the FCR and palmaris longus can be palpated anterior to the wrist, a little lateral to its middle.
Which tendons are located within the anatomical snuff box?
The anatomical snuff box contains the tendons of the abductor pollicis longus (APL), extensor pollicis brevis (EPB), and extensor pollicis longus (EPL).
What is the anatomical snuff box?
The anatomical snuff box is a depression on the dorsum of the hand, bordered by the tendons of APL, EPB, and EPL.
What tendons are visible on the dorsum of the hand?
Tendons of the extensor digitorum, EPL, and APL can be observed on the dorsum of the hand.
Which muscles form the eminences on the palmar aspect of the hand?
The thenar and hypothenar muscles form the thenar and hypothenar eminences on the palm.
What is the significance of the radial longitudinal crease on the palm?
The radial longitudinal crease runs along the base of the thumb and separates the thenar eminence from the rest of the palm.
