Peripheral Nerve Summary

These flashcards cover the key concepts related to peripheral nerves, indicating their functions and areas of innervation as discussed in the lecture.

Phrenic Nerve

Plexus:

Innervates:

Innervates the diaphragm; relevant models include the spinal board and plaster man.

Musculocutaneous Nerve

Plexus:

Innervates:

Innervates the anterior arm for motor and the anterolateral forearm for sensory; relevant models include the thoracic cage, arm, and full body.

Median Nerve

Plexus:

Innervates:

Innervates most of the anterior forearm and lateral hand for motor and the lateral palmar surface for sensory; relevant models include the thoracic cage, arm, full body, and hand.

Ulnar Nerve

Plexus:

Innervates:

Innervates the medial-most anterior forearm and deep hand for motor and the medial palmar and dorsal surface of hand and fingers for sensory; relevant models include the thoracic cage, arm, full body, and hand.

Radial Nerve

Plexus:

Innervates:

Innervates the posterior arm for motor and the posterior arm and proximal posterior forearm for sensory; relevant models include the thoracic cage, arm, full body, and hand.

Deep Radial Nerve

Plexus:

Innervates:

Innervates the posterior forearm for motor; relevant models include the arm, full body, and hand.

Superficial Radial Nerve

Plexus:

Innervates:

Provides sensory innervation to the distal posterolateral forearm and posterolateral hand; relevant models include the arm, full body, and hand.

Axillary Nerve

Plexus:

Innervates:

Innervates the shoulder for motor and sensory; relevant models include the thoracic cage, arm, and full body.

Intercostal Nerves

Plexus:

Innervates:

Innervate the thoracic wall for motor and sensory; relevant models include the spinal board, plaster man, and full body.

Femoral Nerve

Plexus:

Innervates:

Innervates the anterior thigh for motor and sensory; relevant models include the spinal board, leg, and full body.

Saphenous Nerve

Plexus:

Innervates:

Innervates the anteromedial leg for sensory; relevant models include the leg and full body.

Genitofemoral Nerve

Plexus:

Innervates:

Innervates the cremaster muscle in males for motor and supplies the superoanterior thigh and skin of the genitalia for sensory; relevant model includes the spinal board.

Obturator Nerve

Plexus:

Innervates:

Innervates the medial thigh for motor and sensory; relevant models include the spinal board, leg, and full body.

Sciatic Nerve

Plexus:

Innervates:

Has various branches and innervates the posterior thigh and leg; relevant models include the spinal board, leg, and full body.

Tibial Nerve

Plexus:

Innervates:

Innervates the posterior thigh and leg for motor and sensory; relevant models include the spinal board, leg, full body, and foot.

Medial Plantar Nerve

Plexus:

Innervates:

Innervates the medial plantar surface of the foot for motor and sensory; relevant model includes the foot.

Lateral Plantar Nerve

Plexus:

Innervates:

Innervates the lateral plantar surface of the foot for motor and sensory; relevant model includes the foot.

Common Fibular Nerve

Plexus:

Innervates:

Provides sensory innervation to the posterolateral and anterolateral leg; relevant models include the leg, full body, and foot.

Deep Fibular Nerve

Plexus:

Innervates:

Innervates the anterior leg and dorsal foot for motor and supplies sensation to the skin between the 1st and 2nd toes; relevant models include the leg, full body, and foot.

Superficial Fibular Nerve

Plexus:

Innervates:

Innervates the fibularis muscles for motor and provides sensory to the anterior ankle and dorsal foot; relevant models include the leg, full body, and foot.

Lumbar Plexus

Plexus:

Innervates:

Gives rise to nerves supplying the abdominal wall and genitals.

Sacral Plexus

Plexus:

Innervates:

Gives rise to nerves supplying the gluteal and perineal regions.
