Sciatic(ScN) and femoral (FN) nerve

(C) Corresponding transverse ultrasound image of the ScN. The two components of the ScN are readily distinguished and appear as two hypoechoic tubular st
ructures surrounded by a thin hyperechoic rim. (1*) peroneus communis nerve, and (1**) tibialis nerve. (D) Local anaesthetic solution surrounding the ScN showing the characteristic ‘donut sign’. (1) ScN, (2) biceps femoris muscle, (3) femur, (4) adductor magnus muscle, (5) local anaesthetic solution. Prox, proximal; Dis, distal; Cr, cranial; Cd, caudal; Med, medial; Lat,
lateral.

dog: an anatomical study."

Ultrasound image of the iliopsoas muscle (IPM) in transverse section.

The external iliac artery (EIA) is located medial to the IPM and the femoral nerve (FN) is identified as a round hypoechoic structure within the muscle.

Ultrasound image of the lateral aspect of the pelvic limb.

The sciatic nerve (ScN) is located medial to the biceps femoris muscle and is identified as two ovoid hypoechoic structures with the cranial component (peroneal nerve) being smaller than the caudal component (tibial nerve) in transverse section.
