Volar aspect of forearm

Left palmaris longus muscle

The palmaris longus muscle is essentially absent in the right forearm shown in 97-1. Only a slender tendon extends into the antebrachial fascia. In the opposite forearm, shown here, the palmaris longus is well-developed. In addition, an accessory tendinous slip (10) extends proximally from the tendon of the palmaris longus to blend into the antebrachial fascia. The radial artery originates from the brachial artery at a high level.
