肌肉的近端叫origin,远端叫insertion。肌肉的舒张将两端的骨骼拉近。骨骼的几何形状通常近似为多段线(polyline),它起始于肌肉的origin,然后经过一系列的watpoints,最后终止于insertion。 多段线相对于直线可以更好的近似肌肉在origin和insertion之间的长度。waypoint的位置通过linear blending skinning(LBS)函数近似: \tag{...
Origin, insertion, innervation and functions of the biceps brachii muscle. Biceps brachii muscle (Musculus biceps brachii) The biceps brachii muscle is one of the chief muscles of the arm. The origin at the scapula and the insertion into the radius of the biceps brachii means it can act...
action, the attachment is called an origin. If the place is on the bone that moves during the action, the attachment is called an insertion. The triceps brachii happens to have four points of attachment:one insertionon the ulna andthree origins(two on the humerus and one on the scapula)....
This study assessed 40 forearms from 20 cadaveric specimens to determine the prevalence of the origin and insertion of the Gantzer muscle. Furthermore, innervation was assessed along with the potential for nearby nerve compression. Gantzer muscles were present in 26 of 40 (65.0%) forearms, and...
Insertion: Occ Bone- inner third of inferior nuchal line Innervation: C1- posterior ramus (suboccipital nerve) Rectus Capitus Posterior Minor Action Bilateral: Extends head Unilateral: Rotates head to same side Obliquus capitis superior Origin: C1- transverse process ...
When the E-1 electrode is located directly over a current sink, the instrument's trace moves in the negative direction. The action potential induced in the muscle tissue then propagates in opposite directions toward the muscle's origin and insertion (Fig. 2-22B). Two negative sinks, ...
(origin) and to the phalanges of the digits at the other (insertion). When the muscle contracts to flex the fingers, the digits and the wrist move. The specific movement caused by a muscle is its action. In the example given, the muscle's action is flexion of the wrist and digits, ...
Origin Superficial part: Tuberosity of maxilla, Pyramidal process of palatine bone Deep part: Medial surface of lateral pterygoid plate of sphenoid bone Insertion Medial surface of ramus and angle of mandible Action Bilateral contraction - Elevates and protrudes mandible Unilateral contraction - Media...
Discover the functionality of the mentalis muscle, its origin, insertion, action and arterial supply. Learn about its role in facial expressions and drinking.
