The superficial muscles in the gluteal region consist of the three glutei and the tensor fascia lata. The muscle belly forms a tendon, which descends with the fibularis longus into the foot. The gluteus maximus is the largest of the gluteal muscles. Protection for the Brain: Meninges, CSF, Blood-Brain Barrier It is also the most superficial, producing the shape of the buttocks. It is the mass action muscle so act as the main gripping power of the hand because the tendons of the flexor digitorum profundus arise at or below the wrist joint (whereas tendons of flexor digitorum superficially arise in distal 3rd of the forearm).. The Superficial Muscles. Connective Tissue Basics The Peripheral Nervous System It travels posteriorly to the lateral malleolus, passing over the calcaneus and the cuboidal bones. Common flexor origin: Medial epicondyle But remember that the 3 muscles containing U have more attachments: Ulnar (deep) head of pronator teres (may be absent): Ulna (coronoid process); Flexor Carpi Ulnaris: Ulna (olecranon) and Ulnar shaft; Flexor digitorum sUperficialis: Ulna (coronoid) and Radial WebThe flexor muscles are more massive than the extensors because they work against gravity and act as anti-gravity muscles. The flexor digitorum superficialis courses along the volar aspect of the forearm, superficial to the flexor digitorum profundus and flexor pollicis longus muscles, and deep to the palmaris longus, flexor carpi radialis, flexor carpi ulnaris, and pronator teres. Innervation of the skin: Dermatomes WebThe flexor digitorum profundus is a muscle in the forearm of humans that flexes the fingers (also known as digits). It is one of the deep muscles of the anterior compartment (deep volar compartment) of the forearm. Most of these originate from the lateral epicondyle. These three muscles form the fleshy mass at the base of the little finger, and are solely concerned with the movement of digit V. The other two muscles that make up the hypothenar muscle group are the abductor digiti minimi and the opponens digiti minimi. It arises by two muscle heads (superficial and deep) which are separated by the tendon of flexor pollicis longus.The superficial head originates from the flexor retinaculum and the tubercle of the trapezium bone, while the deep head originates from the trapezoid and capitate bones. These nerves control the forearm muscles that move the hands and fingers through tendons that pass through the Cartilage and Bones The ulnar nerve and artery are also contained within this compartment. The Carpal tunnel is formed by two layers, deep carpal arch and superficial flexor retinaculum. The Endocrine System (Pituitary, Thyroid, Pancreas, Adrenal, Gonads, etc) The extensors are situated within 6 separate compartments. Intro to the Heart ; Intermediate associated with movements of the thoracic cage. Myocardium The tendons unite with the interosseous and lumbrical muscles to form the extensorhood mechanism.
