Muscles of the Pelvic Limb

Question 1

*Muscles of the Loin, Hip and Thigh

consists of:

a) psoas major
b) iliacus

Answer 1

Iliopsoas

Question 2

situated lateral to psoas minor,
ventral to quadratus lumborum, as it continues
caudally it becomes thicker and wider and is
reinforced by muscle fibers of iliacus from ventral
surface of the ilium.

Answer 2

Psoas major

Question 3

*Muscles of the Loin, Hip and Thigh

• located ventral to the quadratus lumborum;
• more cranial than the psoas major;
• arises from lateral thoracic vertebrae/lumbar
  vertebrae;
• tendon will insert on the arcuate line.
  Supplied by the ventral branches of the
  lumbar nerves

Answer 3

Psoas minor

Question 4

*Muscles of the Loin, Hip and Thigh

• triangular muscle from coxal tuber
• spreads out laterally to quadriceps femoris at the
  level of the greater trochanter
• it joins the fascia lata

Answer 4

Tensor fasciae latae

Question 5

continues distally lateral to the
quadriceps to the patella

Answer 5

Fascia lata

Question 6

*Muscles of the Loin, Hip and Thigh

extends from sacrum and 1st caudal
vertebra and the proximal part of the sacrotuberous
ligament; inserts on the trochanter tertius; most caudal

Answer 6

Gluteus superficialis

Question 7

*Muscles of the Loin, Hip and Thigh

largest of the gluteal muscles; extends from entire gluteal surface of the ilium; inserts on the trochanter major of the femur; innervated by cranial gluteal
nerve

Answer 7

Gluteus medius

Question 8

*Muscles of the Loin, Hip and Thigh

completely covered by the gluteus medius and the piriformis; arises from the lateral border of the shaft of the ilum from the wing to the ischiatic spine;
inserts on the trochanter

Answer 8

Gluteus profundus

Question 9

*Muscles of the Loin, Hip and Thigh

• extends from lateral border of the sacrum and the
  dorsal end of the sacrotuberous ligament in the
  region of the major ischiatic notch;
• lies deep to the inserts with the caudal portion of
  the gluteus medius;
• innervated by cranial gluteal nerve

Answer 9

Piriformis

Question 10

Note: gluteal muscles and piriformis are
extensors of the hip joint

Answer 10

Note: gluteal muscles and piriformis are
extensors of the hip joint

Question 11

*Lateral Rotators of the Limb

arises from the inner
surface of the pelvic floor; covers the obturator
foramen

Answer 11

Internal Obturator m.

Question 12

*Lateral Rotators of the Limb

arises from the lateral border of
the ischium

Answer 12

Gemelli

Question 13

*Lateral Rotators of the Limb

arises medial to the
ischiatic tuber

Answer 13

Quadratus femoris
