(2003) states that the dorso-ulnar corner of the AS contains only the tendon of extensor carpi radialis longus muscle, but according to Tubbs et al., the tendon of extensor carpi radialis brevis can also be found in the AS, depending on how distal the retinaculum of extensor muscles is, and how medial the dorsal tubercle of the radius is found.
During the following 5 to 10 minutes we verify the death signs (respiratory failure, absence of heart beat and opaque cornea) and subsequently we dissected soleus and extensor carpi radialis longus muscles. The samples were directly fixed by freezing using 2-methyl butane (isopentane) cooled in liquid nitrogen, stored at -70[degrees]C and cut on cryostat Leica Jung Frigocut 2800N at -20[degrees]C and 16 ums.
