N. PEEON^.us PROFUNDUS. — The deep peroneal nerve crosses the 

 proximal part of the long peroneal muscle, sinks into the interval 

 between this muscle and the extensor digitoruni longus and early 

 expends a considerable amount of its fibres in the supply of branches 

 to these muscles and the tibialis anterior. The much reduced continua- 

 tion of the nerve runs down the groove formed by the lateral border

of the long extensor and the anterior tibial muscles, and then follows 

 the lateral border of the long extensor to the flexor aspect of the tarsus, 

 where it divides into medial and lateral branches. 



The medial branch (ramus medialis) runs obliquely down the dorsal 

 surface of the metatarsus, and ends in the skin over the dorsal and 

 medial aspect of the metatarso-phalangeal joint. The lateral branch 

 (ramus lateralis) supplies the extensor digitorum brevis, passes under- 

 neath the tendon of the peron^eus longus in company with the lateral
