오늘은 하지를 지배하는 신경, 근육, 그리고 근육들의 움직임에 대해서 알아보겠습니다.

하지 신경 (Lower extermity nerve)

먼저 하지 신경을 크게 두가지로 나누어 보자면 운동신경과 감각신경으로 나눌 수 있습니다.

★ Hip/Thigh

1) 운동신경 (Motor)

- Obturator nerve

- Femoral nerve

- Sciatic nerve

- Superior gluteal nerve

- Inferior gluteal nerve

2) 감각신경 (Sensory)

- Lateral femoral cutaneous nerve

- Obturator nerve

- Femoral nerve

★ Leg/foot

1) 운동신경 (Motor)

- Tibial nerve

- Common peroneal

: Deep peroneal nerve/Superficial peroneal nerve

2) 감각신경 (Sensory)

- Sural nerve

- Saphenous nerve

- Deep peroneal nerve

- Superfical peroneal nerve

- Tibial nerve

해당 신경들을 하나씩 살펴보도록 하겠습니다.


▣ Obturator nerve (폐쇄신경)

Origin : L2, L3, L4 (요신경 2,3,4 번에서 origin)

Motor innervation

: Hip adduction

Muscle innervation

- 주로 허벅지 안쪽 근육들을 지배하고 있습니다.

: Medial leg and foot (via saphenous nerve)

Terminal branch
