Sartorius m.
Heads?

Origin

Insertion

Action

Innervation

Cranial and caudal

Origin:
Cranial - crest of the ilium and thoracolumbar fascia
Caudal- iliac spine and border of the ilium

Insertion:
Cranial: the patella (like rectus femoris)

Caudal - the cranial border of the tibia (like gracilis)

Action: to flex hip joint (both)
cranial - extend stifle joint
caudal - flex stifle joint

innervation: femoral nerve

2

Gracilis m.

Origin

Insertion

Action

Innervation

Origin: pelvic symphysis by the symphysial tendon

Insertion:
cranial border of the tibia (3 others)

Action
to adduct the limb, flex the stifle joint, and extend the hip and tarsal joints

Innervation
Obtrurator nerve

3

What is the symphysial tendon?

thick flat tendon that the gracilis muscle arises from. the tendon attaches to the symphysis pelvis

4

Who inserts on the cranial border of the tibia? (4)

biceps femoris
semitendinosous
tuber calcanei
gracilis

5

femoral triangle

triangular space where the femoral vessels run to and from the pelvic limb

6

Pectineus Muscle
Action
Innervation

Action: adduct limb
Innervation: Obtrurator nerve

7

Adductor
Origin
Insertion
Action
Innervation

Origin:

- adjacent part of the ischiatic notch
- ventral part of the pubis and ischium?

Insertion:
lateral lip of the caudal rough surface of the femur

Action:
adduct the limb and extend the hip joint

Innervation:
Obturator nerve
