What is the antebrachial fascia?
The antebrachial fascia or deep fascia of the forearm is a thick connective tissue fascia investing the muscles of the forearm.
Where is the Antebrachial region?
the area of the upper limb between elbow and hand.
What are the Thickenings of the antebrachial fascia?
The median nerve may be compromised by the lacertus fibrosus, which is a thickening of the antebrachial fascia or bicipital aponeurosis that attaches the biceps muscle to the ulna.
What is palmar fascia?
The palmar fascia is a triangular structure in the palm of the hand based distally (Fig. 1). It is a continuation of the deep fascia of the forearm. The palmaris longus, when present, lies freely between the superficial and deep layers of the deep fascia.
Does Antebrachial mean forearm?
The forearm, i.e. the part of the arm between the elbow and the wrist. The term is used in anatomy to identify it from the brachium (or the upper arm). Word origin: from Latin, prefixal form of prep.
What is lateral to the Antebrachial region?
The lateral antebrachial cutaneous nerve (or lateral cutaneous nerve of forearm) (branch of musculocutaneous nerve, also sometimes spelled “antebrachial”) passes behind the cephalic vein, and divides, opposite the elbow-joint, into a volar and a dorsal branch. Lateral cutaneous nerve of forearm.
What two bones are found in the Antebrachial region?
The forearm is the region of the upper limb located between the elbow and wrist joints. This region contains two bones, the ulna medially and the radius on the lateral (thumb) side.
What is fascia and its function?
Fascia is an abundant connective tissue in the body and is intricately woven around organs as well as wrapped around every individual muscular fiber. It is the ultimate connective tissue, as one of its primary functions is connecting different bones, organs, and other soft tissues together.
What is palmar fascia made of?
The palmar fascia, which in Dupuytren disease is abnormal, is composed of thenar, hypothenar, and palmar aponeuroses; palmar is involved most often (Fig. 84.4). Normal anatomy has bands of aponeurosis. These bands, when diseased, become the pathologic cords of Dupuytren disease.
What is thenar space?
The thenar space is one of the three deep palmar spaces. It is rarely the site of hand infections. The fibrofatty space contains the first lumbrical muscle. Relations: ulnarly: midpalmar septum from border of palmar aponeurosis to palmar border of third metacarpal bone.
Why is it called the antebrachium?
The term is used in anatomy to identify it from the brachium (or the upper arm). Word origin: from Latin, prefixal form of prep. and adv. ante-, meaning “before” + brāc(c)hium, meaning the arm.
How do you say calcaneal?
noun, plural cal·ca·ne·i [kal-key-nee-ahy]. Anatomy.
Is the Antebrachial region distal to the brachial region?
Answer and Explanation: The correct phrase is: The brachial region is superior to the antebrachial region.
What is the antecubital region?
Introduction. The cubital fossa is an area of transition between the anatomical arm and the forearm. It is located in a depression on the anterior surface of the elbow joint. It is also called the antecubital fossa because it lies anteriorly to the elbow (Latin cubitus) when in standard anatomical position.
What is the topographic location of the brachial fascia?
It spans the axilla and the cubital fossa, and is bounded ventrally by the biceps brachii and brachialis muscles, dorsally by the triceps brachii and medial intermuscular septum of the arm, superficially by the brachial fascia, and deeply by the humerus.
What is the antebrachial fascia of the forearm?
The antebrachial fascia (antibrachial fascia; deep fascia of the forearm) continuous above with the brachial fascia, is a dense, membranous investment, which forms a general sheath for the muscles in this region; it is attached, behind, to the olecranon and dorsal border of the ulna, and gives off from its deep surface numerous intermuscular se…
What is the difference between antebrachial fascia and median nerve?
The antebrachial fascia is sharply incised, and the median nerve is identified lying deep and ulnar to the PL. The FDS tendons are identified and retracted ulnarly with the median nerve, and the FCR tendon is identified and retracted radially.
What muscles expand to the brachial fascia?
For example, there are expansions of pectoralis major muscle to the brachial fascia, continuing via lacertus fibrosus and biceps muscle to the antebrachial fascia and flexor carpi radialis, then to the flexor retinaculum, and finally to the palmaris longus muscle connecting to the fascia of the thenar eminence [13].
How is the incised antebrachial fascia (FDS) and median nerve (FDP) identified?
The skin is incised sharply; sharp dissection is used to expose the antebrachial fascia. The antebrachial fascia is incised, and the musculotendinous units of the FDS and FDP are identified. The median nerve is identified between FDS and FDP. The FDS and the median nerve are gently retracted radially in order to achieve adequate exposure.
