Articularis genu is a vestigial muscle considered as the 5th part of the quadriceps. This is represented as the detached fibre bundles from the vastus intermedius. Morphologically the muscle is flat, thin, wispy. It shows highly variable attachments taking origin from the lower 1/4th of anterior surface area of the femoral shaft. Articularis genu may be considered as 5th head of quadriceps femoris. The variant morphology of the muscle may prevent incidental removal during total knee replacement, investigating osteoarthritis and so more.

Hand is an organ of prehension. Human hand is an example of revolution in evolution. It is endowed with skilled movements. It consists of different group of muscles, ligaments, joints which are responsible for the fine movements of hand. It also contains neurovascular structures which are the terminal branches of median nerve, ulnar nerve and radial nerve. The terminal branches of ulnar and radial arteries provide the arterial supply. Here, we have reported the variant of lumbrical muscles. Lumbricals perform movements on metacarpophalangeal joints, proximal interphalangeal joints and distal interphalangeal joints. Lumbricals are spindle rich fibres. Variations in the structures present are immensely important for the orthopaedic surgeon, digital transposition surgery, cleft hand surgery etc. Anatomically, incursion of the lumbricals inside the carpal tunnel may lead to work related carpal tunnel syndrome.
