Basic Muscles • Rectus Femoris • Gluteus Maximus • Gastrocnemius • Rectus Abdominus
Rectus Femoris • The rectus femoris muscle is one of quadriceps muscles. • It goes from the hip to the knee and can be used to straighten the knee or lift the knee up.
Rectus Femoris • Origin: • anterior head: anterior inferior iliac spine (AIIS) • posterior head: ilium just above the acetabulum • Attachment: • common quadriceps tendon into patella • patellar ligament
Gastrocnemius • the muscle in the back part of the leg that forms the greater part of the calf • the most superficial of the muscles of the posterior compartment of the lower limb distal to the knee. • It acts to plantar flex the foot at the ankle and raise the heel during walking
Gastrocnemius • Origin: • medial head: just above medial condyle of femur • lateral head: just above lateral condyle of femur • Attachment: • Achilles Tendon
Gluteus Maximus • is one of the largest and strongest muscles in the body. • the most superficial muscle in the gluteal region • broad and thick fleshy mass of a quadrilateral shape. • Extends and rotates hip. Maintain knee extension.
Gluteus Maximus • Origin: • outer rim of ilium • dorsal surface of sacrum and coccyx • sacrotuberous ligament • Attachment: • IT band (primary insertion) • gluteal tuberosity of femur
Rectus Abdominus • Rectus abdominis controls the tilt of the pelvis and curvature of the lower spine. • Also known as abs
Rectus Abdominus • Origin: • pubis • Insertion: • cartilage of 5th - 7th ribs
