FORE ARM
The fore arm is the region between the Shoulder and the wrist. Anatomically describe as a region that is bounded or bordered between the Olecranon Process of the Ulnar and the Olecranon Process of the Humerus. Superiorly down to the joint between the Ulna and Radius of the Scapula bone.
Inferiorly IT is bounded by the wrist joint and bounded by the Carpal bone and ulna of the radius.
Two bone Come towards the wrist.
“8 pieces” of bone at the wrist, The Carpals bones form the inferior border of the forearm
Fore arm two main parts
* Anterior Surface, flexor Surface Compartment, these is the area that can be flexible.
* Entensor Compartment
Muscles of the flexor
8 muscles of the fore arms divide into two:
* Superficial muscles
* Deep muscles
Superficial are five in number and Deep muscle are 3 in numbers:
Superficial Muscles
* Pronator Teres – palm facing forward.
* Flexor Carpi Radialis muscle.
* Palmaris Longus
* Flexor Carpi Ulnaris
* Flexor Digitorum Superficial (DEEP flexor)
* Flexor Digitorum Profundus.
* Pronators Quadratus
* Flexor Pollicis Longus.
Muscle in Gross Anatomy
Three major Sub heading
* Origin – The Proximal attachus – where the muscle is arising from.
* Tendon – the flesh attaches to the bone.
* Point of Insertion – Point where the tendon of the muscles attaches with the bone.
* Nerve Supply – Three major vessel that nerve the Arteries, Nerves, Vein
Pronator Teres
* Arteries (Red)
* Vein (Blue)
Diffrences (P.O.V)
* Nerves (Yellow) Responsible for transmission of Impulses. To both the muscles and the brain.
Nerve Supply
* Action – Function of the muscles.
Pronator teres muscles arise by two numbers:
* Superficial head – from medial epicondyle of the Humerus.
* Deep head – from the Coronoid process of the Ulna.
Insertion – In the insertion the fibre of the Pronator teres is inserted into the one third of the lateral surface of the radius of the median bone
Nerve Supply – is the supply by the median nerve
