Hip adductors muscles in human body

The following muscles are called hip adductors.

Adductor longus and adductor brevis

Adductor Magnus

Gracilis

1. Adductor longus and adductor brevis

-origin -anterior pubis

-insertion- linea aspera on posterior femur

Nerve supply- obturator(l3,4)

Action- adduction of femur at the hip, assist flexion and medial rotation pf femur at the hip

Palpation – adductor longs-prominent cord-like origin at media aspect of groin during active adduction of hip

-adductor brevis-may attempt to palpate laterally to adductor longus origin on the pubis.

Adductor longus forms the medial border of the femoral triangle.

Adductor Magnus

-origin- pubic ramus, ischial tuberosity, and ramus

-insertion- linea aspera of posterior femur, adductor tubercle of medial femur

-nerve supply- anterior -obturator nerve(l2,3,4)

-posterior-sciatic nerve(l4,5,s1,2,3)

Action- adduction of the femur at hip joint, assist medial rotation of femur at hip, anterior fibers assist flexion of the femur at hip, posterior fibers assist Extention of femur at hip

Palpation- surface of thigh just medial to gracilis during active adduction of hip.tendon palpated at its insertion on the adductor tubercle

Adductor hiatus – emergence of femoral artery and femoral vein to poplitial fossa behind knee.

3. Gracilis

-origin- anterior pubis

-insertion- medial proximal tibia

-nerve supply- obturator nerve(l2,3,4)

Action- adduction of femur at hip ,assist flexion and medial rotation of flexed knee

-palpation- a few inches below pubic bone on medial side of thigh during active hip adduction.tendon palpated on medial side of posterior knee ,medial to semitendinosus tendon

-this is the most superficial and medial of the adduxtors .the femoral shaft and the gracilis form tge shape of the letter 'v'.

What is Anatomical pulley? Example of Anatomical pulley

Understanding the Importance of Anatomical Pulleys in Physiotherapy As a physiotherapy student, it is essential to have a good understanding of the human body's anatomy and how it works. One of the essential structures in the body that plays a significant role in movement and biomechanics is the anatomical pulley. In this article, we will explore what an anatomical pulley is, its types, and its importance in physiotherapy. What is an Anatomical Pulley? A pulley is a simple mechanical machine that consists of a wheel that turns readily on the axle, usually grooved for a rope or a wire cable. In the human body, the pulley is replaced by a bone, cartilage, or ligament, and the cord is replaced by a muscle tendon. The tendon is lubricated by synovial fluid, and the surface of the tendon is covered by a thin visceral synovial membrane. The tendon is lubricated so that it may easily slide over the pulley. Classification of Anatomical Pulleys There are mainly four classes of pulleys

Electrotherapy Simplified by Basanta Kumar Nanda PDF Download

Electrotherapy Simplified by Basanta Kumar Nanda The aim of this book is to focus on the electrotherapy simplified. Electrotherapy is one of the important aspects among the various approaches of patient management available to a physiotherapist. Electrotherapy Simplified has tried to give comprehensive knowledge on electrotherapy and actinotherapy, starting from basic electricity and magnetism to the theoretical and clinical aspects of the different modalities applied by physiotherapists. This book consists of 19 chapters, which include an introduction, inflammation, repair, and role of physical agents, electrical fundamentals, magnetic energy, valves, transistors, and rectifiers, electrical measurement systems and distribution of electricity, electrophysiology of nerve transmission, and muscle contraction, low-frequency currents, electrodiagnosis, medium frequency currents, low-intensity laser therapy, ultraviolet radiation, and traction. About 250 objective question answers have b

Range of Muscle work in Physiotherapy

The degree of the movement done by muscle contraction is known as the Range of muscle work. The range can be measured with the help of a goniometer. Movement is a very complex mechanism, a lot of muscles are working in a group and in synchronized pattern to draw out the perfect desirable movement. As per function we already talked about Agonist, antagonist, Synergist, and fixator muscles.
