Nerve Distribution and Function

This set of flashcards covers the important nerves, their functions, and the areas they innervate based on the provided lecture notes.

Sacral Nerves

Control sensation from the genitals and lower abdomen, and motor function for the perineum and lower limb.

Coccygeal Nerve

A sacral nerve responsible for sensation in the coccygeal region without any motor function.

Dorsal Scapular Nerve

Innervates the levator scapulae and rhomboid major/minor muscles.

Long Thoracic Nerve

Innervates the serratus anterior muscle, vital for shoulder movement.

Suprascapular Nerve

Innervates the supraspinatus and infraspinatus muscles.

Upper Subscapular Nerve

Innervates the upper part of the subscapularis muscle.

Lower Subscapular Nerve

Innervates the lower part of the subscapularis and teres major muscles.

Medial Pectoral Nerve

Innervates the pectoralis major and minor muscles.

Lateral Pectoral Nerve

Primarily innervates the pectoralis major muscle.

Thoracodorsal Nerve

Innervates the latissimus dorsi muscle, important for arm movement.

Medial Cutaneous Nerve of the Arm

Provides sensory innervation to the skin of the medial arm.

Medial Cutaneous Nerve of the Forearm

Supplies sensory innervation to the skin of the medial forearm.

Iliohypogastric Nerve

Supplies sensation to the skin of the inferior abdomen and motor function to abdominal muscles.

Ilioinguinal Nerve

Provides sensation to the skin of the groin, and motor function to abdominal muscles.

Genitofemoral Nerve

Innervates the skin of the genitals and upper medial thigh.

Lateral Cutaneous Nerve of the Thigh

Provides sensory innervation to the skin of the lateral thigh.

Superior Gluteal Nerve

Innervates the gluteus medius, gluteus minimus, and tensor fasciae latae muscles.

Inferior Gluteal Nerve

Innervates the gluteus maximus muscle.

Nerve to Obturator Internus

Innervates the obturator internus and superior gemellus muscles.

Nerve to Quadratus Femoris

Innervates the quadratus femoris and inferior gemellus muscles.

Pudendal Nerve

Innervates perineal muscles and provides sensation to the skin of the genitals.

Posterior Cutaneous Nerve of the Thigh

Provides sensory innervation to the skin of the posterior thigh.
