Quadriceps Quadriceps. Quadriceps, 4.3 out of 5 based on 5 ratings. The Quadriceps Femurs which derives it’s name from the Latin, meaning four headed muscle of the femur can be subdivided into four muscles or heads. These are the Vastus Intermedius, the Vastus Lateralis, the Vastus medialis and the Rectus Femoris. The Rectus Femoris muscle is the fourth muscle making up the Quadraceps occupying the middle of the thigh covering most of the other three muscles making up the quadriceps. 2  It has two tendons with origin attachment points from the anterior inferior iliac spine as well as from just above the Acetabulum.

- Hamstrings 101. The hamstring group comprises three muscles and their tendons, which originate on the ischial tuberosity (the part of the hip you sit on), flow down the back of the thigh and attach to the front and back of the knee.

NBA Finals: The greatest records Bill Russell won 11 titles in Boston, more than any other player in league history. The Lakers' Jerry West has scored more points in the Finals -- 1,679 -- than most players have scored in their whole careers. Ray Allen hit the most 3-pointers in a Finals game when he sank eight for Boston in 2010. The Lakers' Magic Johnson dished a Finals-record 21 assists in 1984.

Learn Muscle Anatomy: Lateral Rotators Superior and Inferior Gemellus. The superior gemellus and inferior gemellus are long, thin muscles that originate on the ischium and insert on the medial surface of the greater trochanter. Both muscles, in addition to helping rotate the hip joint laterally, help to abduct the flexed thigh.

Vastus Intermedius Anatomy: Origin, Insertion, Action, Innervation Insertion: Into the quadriceps tendon along with rectus femoris and the other vasti muscles, enveloping the patella, then by the patellar ligament into the tibial tuberosity. Action: Extension of the leg at the knee. Innervation: Posterior division of the femoral nerve (L3 – 4)

Medical Definition of Trochanter The lesser trochanter - A pyramidal prominence that projects from the proximal (near) and medial (inside) part of the shaft of the femur. The lesser trochanter is also called the minor trochanter, the inner trochanter, and the medial process of the femur. The trochanters are points at which hip and thigh muscles attach.

Muscles of the Gluteal Region The gluteus minimus is the deepest and smallest of the superficial gluteal muscles. It is similar is shape and function to the gluteus medius. 1  Attachments: Originates from the ilium and converges to form a tendon, inserting to the anterior side of the greater trochanter.he deep gluteal muscles are a set of smaller muscles, located underneath the gluteus minimus. The general action of these muscles is to laterally rotate the lower limb. They also stablise the hip joint by ‘pulling’ the femoral head into the acetabulum of the pelvis.

The Piriformis muscle The piriformis muscle originates on the front portion of the sacrum, the triangular bone wedged between the two hip bones, passes under the greater sciatic notch (an opening of the pelvis) and attaches to the top of the greater trochanter, a bony prominence on the outside of the femur (thigh) bone.he piriformis muscle is categorized as one of six deep lateral rotators of the hip and is one of only three muscles that connect the legs to the spine. If you know of your piriformis muscle you probably consider it more of an irritant than a rotator.

Piriformis Trigger Points: Double Trouble Muscle Attachments: The piriformis muscle arises off the anterior (internal) surface of the sacrum and passes through the greater sciatic foramen to exit the pelvis laterally and attach to the greater trochanter of femur.

The Gluteal Muscles Gluteus medius: This muscle originates on the ilium between the anterior and posterior gluteal lines and inserts on the lateral portion of the greater trochanter of the femur. It’s innervated by the superior gluteal nerve.

Gastrocnemius Muscle Anatomy Study: Origin, Insertion, Action and Innervation Gastrocnemius Muscle Anatomy Study: Origin, Insertion, Action and Innervation. Origin: Medial head: the depression at the upper and posterior part of the medial condyle of the femur and continuing behind the adductor tubercle to a slightly raised area on the popliteal surface of the femur, just above the medial condyle.

Rectus Femoris Rectus Femoris Origin. This muscle has two origins – anterior and posterior. The anterior origin is from the bottom of the spine while the posterior one is at the Acetabulum (the cup-shaped hollow space in the hipbone where the tip of the femur fits in to form a ball-and-socket joint).

- Muscles of the gluteal and posterior femoral regions. Gluteus minimus and the origins and insertions of medius and maximus labeled. The gluteal muscles are a group of three muscles which make up the buttocks: the gluteus maximus, gluteus medius and gluteus minimus.The three muscles originate from the ilium and sacrum and insert on the femur.he gluteus maximus is the largest of the gluteal muscles and one of the strongest muscles in the human body. It inserts at the iliotibial band and the gluteal tuberosity of the femur.

Piriformis muscle From Wikipedia, the free encyclopedia. The piriformis (from Latin piriformis =  pear shaped) is a muscle in the gluteal region of the lower limb. It is one of the six muscles in the lateral rotator group. It was first named by Adriaan van den Spiegel, a professor from the University of Padua in the 16th century.he piriformis muscle is part of the lateral rotators of the hip, along with the quadratus femoris, gemellus inferior, gemellus superior, obturator externus, and obturator internus.

About the Hip Joint There are two other protrusions near the top of the femur, known as the greater and lesser trochanters. The muscles involved in hip motion are attached to the joint at these trochanters. The acetabulum is a concave area in the pelvis, into which the femoral head fits.The pelvis is a girdle of bones, connected at the front by cartilage pad, called the pubis, and at the back by the lowest four fused vertebrae (the sacrum).here are two other protrusions near the top of the femur, known as the greater and lesser trochanters. The muscles involved in hip motion are attached to the joint at these trochanters. The acetabulum is a concave area in the pelvis, into which the femoral head fits.

Muscles in the Medial Compartment of the Thigh Obturator Externus. This is one of the smaller muscles of the medial thigh, and it is located most superiorly. 1  Attachments: It originates from the membrane of the obturator foramen, and adjacent bone. 2  It passes under the neck of femur, attaching to the posterior aspect of the greater trochanter.
