The superior cluneal nerves are pure sensory nerves that innervate the skin of the upper part of the buttocks. They are the terminal ends of the L1-L3 spinal nerve dorsal rami lateral branches. They are one of three different types of cluneal nerves (the middle and inferior cluneal nerves being the other two). They travel inferiorly through ...
The cluneal nerves (or clunial nerves) are cutaneous nerves of the buttocks. They are often classified according to where on the buttocks they innervate. Specifically ...
The medial clunial nerves innervate the skin of the buttocks closest to the midline of the body. Those nerves arise from the posterior rami of spinal sacral nerves (S1, S2, and S3). Additional images
The inferior clunial nerves (also gluteal branches of posterior femoral cutaneous nerve) are branches of the posterior cutaneous nerve of the thigh that innervate the skin of the lower part of the buttocks. [1] [2] They pass inferior to the inferior border of the gluteus maximus muscle. [2]
In humans, the buttocks are located between the lower back and the perineum. They are composed of a layer of exterior skin and underlying subcutaneous fat superimposed on a left and right gluteus maximus and gluteus medius muscles. The two gluteus maximus muscles are the largest muscles in the human body.

An action potential (or nerve impulse) is a transient alteration of the transmembrane voltage (or membrane potential) across the membrane in an excitable cell generated by the activity of voltage-gated ion channels embedded in the membrane. The best known action potentials are pulse-like waves that travel along the axons of neurons.
V 1 (ophthalmic nerve) is located in the superior orbital fissure V 2 (maxillary nerve) is located in the foramen rotundum. V 3 (mandibular nerve) is located in the foramen ovale. Receives sensation from the face, mouth and nasal cavity, and innervates the muscles of mastication. VI Abducens: Mainly motor Nuclei lying under the floor of the ...
