The clavicular head originates from the inner part of the clavicle (collarbone). ... Both the clavicular and sternal heads of the pectoralis major insert on the same two locations, which are the bicipital groove of the humerus and the deltoid tuberosity of the humerus. The humerus is the long bone of the upper arm.

The anterior arch forms about one-fifth of the ring: its anterior surface is convex, and presents at its center the anterior tubercle for the attachment of the Longus colli muscles and the anterior longitudinal ligament; posteriorly it is concave, and marked by a smooth, oval or circular facet (fovea dentis), for ...

Palmaris longus is a muscle of the forearm and wrist. It originates at the medial epicondyle of the humerus and inserts, a bit, at the flexor retinaculum. However, its major insertion point is the palmar aponeurosis.

Origin and insertion Levator scapulae originates from the transverse processes of the first four cervical vertebrae. The muscle fibers descend laterally to insert at the superior angle and medial border of scapula, between the superior angle and base of the spine of scapula.

The gluteus medius muscle originates on the anterior gluteal surface of the ilium, between the iliac crest and posterior gluteal line above and the anterior gluteal line below (see photo below), the gluteal aponeurosis (thick fascia covering the gluteus medius) and inserts into the lateral surface of the greater ...

Origin and insertion Quadratus femoris originates from the upper part of the lateral border of ischial tuberosity, inferior to the lower rim of acetabulum. This attachment is superior to the origins of adductor magnus muscle and lateral to the obturator externus muscle.

Origin and insertion Thoracic multifidus originate from the transverse processes of the thoracic vertebrae. The fibers also take a superomedial course to insert variably on the spinous processes of the vertebrae 2 – 5 levels above their origin.
