What is the attachment of bicipital aponeurosis?
Bicipital aponeurosis or lacertus fibrosus is an aponeurosis from the tendon of biceps brachii muscle in the cubital fossa. It gets attached to the deep fascia of the medial side of forearm after covering the brachial, radial and ulnar artery along with the median nerve.
What lies superficial to bicipital aponeurosis?
The bicipital aponeurosis is superficial to the brachial artery and the median nerve, but deep to the median cubital vein. This protection is important during venipuncture (taking blood).
Is the bicipital aponeurosis palpable?
US is performed from the volar aspect of the elbow, where the tendon and free edge of the bicipital aponeurosis are often palpable in the anterior cubital fossa.
What is Lacertus syndrome?
Lacertus syndrome is a chronic exertional compartment syndrome of the forearm that is unlike exertional compartment syndrome of the lower extremity. It differs from traditional exertional compartment syndrome in terms of the anatomy, symptoms and physical exam findings.
What aponeurosis means?
aponeurosis, a flat sheet or ribbon of tendonlike material that anchors a muscle or connects it with the part that the muscle moves. The aponeurosis is composed of dense fibrous connective tissue containing fibroblasts (collagen-secreting spindle-shaped cells) and bundles of collagenous fibres in ordered arrays.
Where is aponeurosis found in the body?
Aponeuroses are important for human movement and posture and are found all over your body, from the tip of your head to the soles of your feet. What, exactly, is an aponeurosis? An aponeurosis is a type of connective tissue that provides a point for a muscle to attach to a bone or cartilage.
Which vein lies anterior to the roof of the antecubital fossa?
median cubital vein
Superficially, in the subcutaneous tissue overlying the cubital fossa are the median cubital vein, lying anterior to the brachial artery, the medial and lateral cutaneous nerves of the forearm, related to the basilic and cephalic veins.
What is cubital fossa?
The cubital fossa is a small triangular area located on the anterior surface of the elbow, with the apex of the triangle pointing distally. It contains some important structures, on their passage from the arm to forearm. [ It is homologous to the popliteal fossa of the lower limb.
What is pronator teres syndrome?
Pronator syndrome, also known as pronator teres syndrome (PST), occurs when the median nerve is compressed in the upper forearm. The median nerve is one of the three nerves that allows our upper extremity to sense and move—it begins in the upper arms and its branches extend into the fingers.
What aponeurosis do you know?
Aponeurosis, a flat sheet or ribbon of tendonlike material that anchors a muscle or connects it with the part that the muscle moves. The aponeurosis is composed of dense fibrous connective tissue containing fibroblasts (collagen-secreting spindle-shaped cells) and bundles of collagenous fibres in ordered arrays.
Why is it called the aponeurosis?
An aponeurosis is made of layers of delicate, thin sheaths. Aponeuroses, also called aponeurotica, function differently than tendons. When a muscle moves by flexing or extending, an aponeurosis acts like a spring to bear the extra pressure and tension. A tendon, on the other hand, moves a bone when a muscle contracts.
What is an aponeurosis give two examples?
The abdominal aponeurosis encloses the long muscles located in the stomach area, from the bottom of the chest to the top of the pubic area. These muscles are called the rectus abdominis muscles. Aponeuroses are thin tissues, and the abdominal aponeurosis is a great example.
