The groin, also known as the inguinal region, is the junctional area between the torso and the thigh. A pulled groin muscle usually refers to a strain of the hip adductor muscles. The adductor muscles of the hip are a group of muscles in the medial compartment of the thigh, which are primarily used for bringing the thighs together. The hip adductors include the adductor longus, adductor brevis, adductor magnus, gracilis, pectineus, and adductor minimus. These muscles help bring the legs together and rotate the hip inwards towards the midline of the body.

What You'll Learn
Adductor Brevis
The adductor brevis is a flat, triangular muscle found in the inner thigh. It is one of the weakest adductors of the thigh. The adductor brevis is located in the middle of the medial compartment of the thigh, lying posterior to the adductor longus and anterior to the adductor magnus. The obturator externus muscle and the medial circumflex femoral artery lie superiorly to the adductor brevis. The adductor brevis muscle runs from the pubis to the medial aspect of the femur. The muscle fibres arise from the anterior surface of the body of pubis, with some fibres originating from the lateral surface of the inferior pubic ramus. The muscle then widens into a triangular shape as it extends inferolaterally towards its insertion on the femur. The adductor brevis inserts on the superior half of the medial lip of the linea aspera, with the insertion continuing halfway down an imaginary line between the lesser trochanter and linea aspera. This insertion is located on the upper third of the femur, medial to the insertion of the adductor magnus and lateral to the insertion of the pectineus muscle.
The adductor brevis is one of the muscles that comprise the adductors of the thigh, along with the adductor longus, adductor magnus, gracilis, and pectineus muscles. These muscles are responsible for producing movements of the hip joint, primarily thigh adduction, but they also participate in flexion, internal and external rotation, and stabilization of the pelvis during standing or walking.
The adductor brevis is innervated by the obturator nerve, which arises from the lumbar plexus (anterior branches of spinal nerves L2-L4). The anterior and posterior branches of the obturator nerve cross the anterior and posterior surfaces of the adductor brevis, respectively, allowing for differentiation from the other adductors of the thigh during anatomical cross-sections and dissections.
Injuries to the adductor brevis can occur due to sudden changes in direction, creating a quick adduction against a large abduction force and stressing the tendon. Risk factors for such injuries include previous hip or groin injuries, age, weak adductors, muscle fatigue, decreased range of motion, and inadequate stretching.

Adductor Magnus
The adductor magnus is one of the hip adductors, and the largest, most powerful and complex muscle of the adductor group. It is a large, triangular muscle that extends over the entire medial side of the thigh. It is a composite muscle consisting of two parts, the adductor part and the ischiocondylar part. The adductor part, also known as the pubofemoral part, arises from the outer surface of the inferior pubic ramus of the pubic bone and the ischial ramus. The adductor part can be further divided into two portions: the superior portion, which arises from the pubic ramus, and the inferior portion, which arises from the ischial ramus.
The adductor magnus has a similar function to the deltoid muscle. One portion of the adductor magnus flexes the thigh and works as a medial rotator, while the other extends the thigh and is a lateral rotator. Both portions adduct the thigh. The adductor magnus is most active during adduction of the flexed thigh when standing, for example, when kicking with the medial side of the foot. The adductor magnus also does not partake in the adduction of the abducted thigh when standing, as gravity alone is enough for that action.
The adductor magnus is palpated on the medial aspect of the thigh while resisting hip adduction against resistance and feeling for the engagement of the musculature. It is also the most posterior of the medial thigh compartment muscles. The hamstring portion of the adductor magnus is innervated by the tibial nerve.

Adductor Longus
The adductor longus is a large, fan-shaped muscle located in the medial aspect of the thigh. It is one of the adductor muscles of the medial thigh and is part of the hip adductors, along with the adductor brevis, adductor magnus, gracilis, and pectineus muscles. The adductor longus is situated most anteriorly in this group, covering the middle part of the adductor magnus and the anterior part of the adductor brevis. It forms the medial border of the femoral triangle and lies in front of the adductor magnus and brevis muscles. The pectineus muscle is lateral to it, while the gracilis lies medially.
The adductor longus muscle plays a crucial role in adducting and externally rotating the thigh, as well as producing some degree of flexion or anteversion. Its primary function is to adduct the thigh at the hip joint, bringing the thigh and knee closer to the body's midline. This muscle also aids in stabilising the pelvis during standing and walking, helping to balance the body on the lower limb.
The adductor longus is innervated by the anterior division of the obturator nerve, specifically the L2-L4 spinal roots. The obturator nerve is a branch of the lumbar plexus and supplies sensation to the upper medial thigh. The blood supply to the adductor longus comes from two arteries: the deep femoral artery (a branch of the femoral artery) and the obturator artery (a branch of the internal iliac artery). The proximal part of the muscle receives its blood supply from the medial circumflex artery, a branch of the deep femoral artery.
Adductor tendinopathy, a common injury in sports such as soccer, football, and karate, can cause medial leg and groin pain. It often occurs due to sudden changes in direction, creating a quick adduction against a large abduction force that stresses the tendon. An early assessment of adductor injuries is crucial to prevent them from becoming career-threatening for athletes.

Gracilis
The gracilis muscle is a long, slender muscle located in the medial (adductor) compartment of the thigh. It is the most superficial of the hip adductors, overlying the remaining four muscles in this group (adductor longus, adductor brevis, adductor magnus, and pectineus). The gracilis is also the weakest of these muscles, but the only hip adductor that crosses and acts on two joints: the hip and knee.
The gracilis muscle is innervated by the obturator nerve, a branch of the lumbar plexus, and receives its blood supply primarily from the 'artery to the adductors', a branch of the deep femoral artery. The gracilis muscle descends almost vertically down the leg, attaching to the coxal bone and tibia at the pes anserinus. This site is also the attachment point for the sartorius and semitendinosus muscles. The pes anserinus is where the gracilis tendon curves and fans out around the medial condyle of the tibia.
The gracilis muscle has several functions. Firstly, it adducts the thigh at the hip and flexes the leg at the knee. It also helps with medial (internal) rotation of the tibia on the femur and leg, which is important for balancing the trunk during walking. The gracilis is prone to strain injuries, particularly in high-impact sports that involve ballistic movements or stretching, such as soccer, hockey, and basketball.

Pectineus
The pectineus muscle is a flat, quadrangular muscle located in the medial compartment of the thigh. It is one of the muscles that adduct the groin, alongside the adductor brevis, adductor longus, adductor magnus, and gracilis. The pectineus muscle arises from the pectineal line of the pubis and the surface of the bone in front of it, extending down to the area just below the lesser trochanter of the femur.
The pectineus muscle is innervated by the femoral nerve (L2 and L3) and, in some cases, by a branch of the obturator nerve called the accessory obturator nerve. It is considered a composite muscle due to its dual innervation. The muscle is classified into both the anterior and medial compartments of the thigh, depending on whether the function or nerve is emphasized.
The primary function of the pectineus muscle is hip flexion, but it also contributes to adduction and external rotation of the hip. It assists in moving the thigh closer to the body's central axis and plays a role in postural control by stabilizing the pelvis and balancing the trunk during walking.
The pectineus muscle can become injured through overstretching, rapid movements, or prolonged periods of sitting with legs crossed. Treatment of a pectineus muscle injury involves protecting the injured area, minimizing activities that use the muscle, and applying ice to reduce swelling and pain.
