The only difference is that you place your fingers a little bit further back. The main action of these muscles is to pull the leg inward. The five muscles usually termed as hip adductors are: 1. Adductor longus muscle (ventral view) The adductor longus is a large, fan-shaped muscle located in the medial aspect of the thigh.It belongs to the adductors of the thigh, together with adductor brevis, adductor magnus, adductor brevis, pectineus and gracilis muscles. When following the pelvis from top/front to bottom/back, this is the order of attachment. The front or anterior part of the muscle, arising from the ischiopubic ramus (where the ramus of both pubic bone and ischium meet). inferior ramus of pubic bone. Attachments: Originates from the body of pubis and inferior pubic rami. origin of gracilis. ... what thigh adductor muscle have an extra action? The adductor muscle group is made up of these muscles: Adductor brevis; Adductor longus; Adductor magnus (including the adductor minimus) Pectineus: the most anterior adductor of the hip. c. Gracilis 5. Together with adductor brevis, adductor magnus, gracilis and obturator externus, it makes up the adductor compartement. The groin muscles consist of three large groups of muscles that can be injured: the abdominal, iliopsoas and adductor group. Adductor longus is innervated by the anterior division of the obturator nerve (L2-L4). Therefore, it can be used as an anatomical landmark to identify the aforementioned branches. The adductor longus lies posterior and medial to the pectineus muscle and is the most anterior of the adductor muscles. Origin: Inferior ramus of the pubic bone Insertion. b. Fibres from the pubic ramus are short and horizontal, and insert along the linea aspera just medial to the gluteus maximus. The adductor magnus is a very large and thick muscle. Adductor Brevis. It lies a little further inside “or” behind the adductor longus. Adductor Longus 3. Adductor Brevis 4. STUDY. The adductor longus arises from the anterior pubic body below the pubic crest via a consistently seen tendon and a deeper, more variable muscular attachment 7 (4a,5a). Groin strains are common injuries to the adductor muscles, which occur without a thorough warm-up or in individuals with chronically tight or weak adductor muscles. Pectineus 2. There is a greater use of them in sports such as soccer, where the adductors are used in kicking a soccer ball with the inside of the foot. 2.3). I listed the muscles in the order above for a reason. The anterior adductor muscle is lost in early ontogeny (the monomyarian condition). It is placed slightly posterior to the visceral mass, stretching transversely between the valves. insertion of gracilis. The adductor stretch will involve the group of muscles that has a considerably large muscle mass. Pubofemoral portion or ‘adductor minimus’ a. medial body of tibia. adduct thigh, flex thigh, rotate thigh medially. The adductor brevis is a short muscle, lying underneath the adductor longus. PLAY. It lies in between the anterior and posterior divisions of the obturator nerve. common action of all thigh adductor muscles. The posterior adductor muscle is large, bean-shaped in cross section, with slightly tapering rounded dorsal end and widely rounded ventral end (Fig. Anterior - Adductors of Thigh. Adductor Brevis is the smallest and shortest (hence the name brevis, meaning short in latin) of the three short adductor muscles. and I just learned about one more in Feb 2018: 6.Adductor Minimus!?
