1
Q
The ______ nerve is the termination of the femoral nerve.
A
•Saphenous
2
Q
Sartorius
A
- Longest muscles in the body
- Most superficial anterior muscle
- Innervation: femoral
- Functions: flex, abduct, laterally rotate thigh, flex leg
3
Q
What three muscles insert on the Pes Anserinus and what are their innervations?
A
- Satorius tendon: femoral nerve
- Gracilis tendon: obterator nerve
- Semitendinosus tendon: tibial portion of the siatic
4
Q
Quadriceps Femoris
A
- Innervation: femoral
- Functions: vasti extend leg, rectus extends leg and flexes thigh
- All 4 parts unite to form quadriceps tendon
5
Q
Pectineus
A
- Attachments: pecten line of pubis (origin), pectineal line (insertion)
- Innervation: femoral, occasionally a branch from the obturator
- Functions: adduct and flex thigh
6
Q
Adductor Longus
A
- Attachments: body of pubis, middle 1/3 of linea aspera
- Innervation: obturator
- Functions: adducts and flexes thigh
7
Q
Gracilis
A
- Long straplike muscle, only adductor to cross knee joint
- Attachments: pubis body and inferior ramus, superior part of medial surface of tibia
- Innervation: obturator
- Functions: adduct thigh, flex and medially rotate leg
8
Q
Adductor brevis
A
- Lies deep to pectineus and adductor longus
- Attachments: pubis body and inferior ramus, proximal linea aspera
- Innervation: obturator
- Functions: adducts and flexes thigh
9
Q
Adductor Magnus Adductor portion
A
- largest adductor muscle
- superior part lies deep to adductor brevis
- Attachment: ischiopubic ramus, distal: gluteal tuberosity, linea aspera, medial supracondylar line
- Innervation: obturator
- functions: adducts and flexes thigh
10
Q
Adductor Magnus Hamstring part
A
- Proximal: ischial tuberosity
- Distal: adductor tubercle (medial epicondyle)
- Innervation: tibial division of sciatic
- Function: adducts and extends thigh
11
