Quadriceps group of muscles in human body

the quadriceps muscle is consist of four muscle

1. -rectus femoris

-vastus intermedius

-vastus medialis

-vastus lateralis

These four large anterior thigh muscles insert below the knee and act to extend the knee joint. the three vast lie deep to the rectus femoris and two have their origins on the posterior femur. the rectus femoris originates on the pelvis and thereby can act to flex the hip.

Quadriceps group of muscles in human body

1.rectus femoris

Origin-long head: anterior inferior iliac spine

short head: upper margin of the acetabulum

Insertion -patella and via patellar ligament to tibial tuberosity

Nerve supply-femoral nerve (l2,3,4)

Blood supply-lateral femoral circumflex artery

Action-Extention of knee

assist flexion of femur at hip

The palpation-anterior surface of the thigh during active knee extension

The Rectus femoris is the only muscle in the quadriceps group that crosses both the hip and knee joints. its combined action is seen as the leg is brought forward in walking.

Remaining three muscles of the quadriceps group

1.vastus medialis

2.vastus lateralis

3.vastus intermedius

*origin-

· Vastus medialis – linea aspera on posterior femur

· Vastus lateralis – linea aspera on the posterior femur, greater trochanter of femur

· Vastus intermedius – anterior and lateral femoral shaft

*insertion – patella and via patellar ligament to tibial tuberosity

*nerve supply – femoral nerve(l2,3,4)

*action- the extension of the knee

*palpation –

· Vastus medialis – anterior medial surface of the lower third of the thigh ,medial to biceps femoris during active knee extension

· Vastus lateralis – lateral surface of thigh, lateral to biceps femoris during active knee extension

· Vastus intermedius – may attempt to palpate under the rectus femoris by pushing this muscle medially during active knee extension. Vastus is the Latin term for immense .these three muscles of the quadriceps group derive their name from their size and position.

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 ...

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.
