The muscle originates from the anterior surface of the body of the pubis, inferior to pubic crest and lateral to the pubic symphysis. It inserts onto the middle third of the medial lip of the linea aspera.

Biceps Femoris – Long Head. Origin: Common tendon with semitendinosus from superior medial quadrant of the posterior portion of the ischial tuberosity. Insertion: Primarily on fibular head; also on lateral collateral ligament and lateral tibial condyle.

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.

Origin and insertion The rectus abdominis muscle is composed of a pair of vertically oriented muscles. ... The medial head originates from the pubic symphysis, interlacing with the fibres of the muscle on the contralateral side. It inserts onto the xiphoid process of the sternum and onto the costal cartilages of ribs 5-7.

As nouns the difference between implant and implantation is that implant is anything surgically implanted in the body, such as a tissue graft or prosthesis, particularly (breast implant)s while implantation is (anatomy) the way in which an organ, bone, muscle etc becomes inserted into its set place.

The serratus anterior muscle originates at the 1st to 9th rib and inserts at the ventral surface of the medial border of the scapula. ... Intermediate part: 2nd to 3rd rib → medial border of the scapula. Inferior part: 4th to 10th rib → medial border and inferior angle of the scapula.

Anatomy. The rectus femoris has its origin on the iliac spine of the hip bone. The other quadriceps muscles have their origins on the femur. ... All four quads insert on the patella (the kneecap) via the quadriceps tendon and on the tibial tuberosity via the patellar ligament.

A vector need not start at the origin: it can be located anywhere! In other words, an arrow is determined by its length and its direction, not by its location.

Origin and insertion Fibularis brevis originates from the distal two-thirds of the lateral surface of fibula and the adjacent part of the anterior intermuscular septum. ... The tendon of fibularis brevis finally inserts on the tuberosity of 5th metatarsal bone, posterior to the insertion of fibularis tertius muscle.

Origin and insertion Gracilis is a thin, flat, long muscle that attaches to the coxal bone and tibia. ... The muscle originates through a thin aponeurosis from three sites located on the ischium and pubis: medial margins of the lower half of the anterior body of pubis. the entire surface of the inferior pubic ramus.

Origin: (proximal attachments): Anterior and lateral surfaces of shaft of femur. Insertion: (distal attachments): Quadriceps tendon to base of patella and onto tibial tuberosity via the patellar ligament.

It originates at anterior superior iliac spine (a bony projection on the uppermost part of the pelvis) and travels to the upper shaft of the tibia, or shinbone. As such, the sartorius is the longest muscle in the human body. The muscle helps flex, adduct, and rotate the hip.
