Foot. Cutaneous innervation of the lower limbs is the nerve supply to areas of the skin of the lower limbs (including the feet) which are supplied by specific cutaneous nerves. Modern texts are in agreement about which areas of the skin are served by which nerves, but there are minor variations in some of the details.
The following is a list of nerves in the human body: Location. Distribution of the areas of the sensory roots upon the surface of the body.
The sural nerve (L4-S1) is a cutaneous sensory nerve of the posterolateral calf with cutaneous innervation to the distal one-third of the lower leg. [1] Formation of the sural nerve is the result of either anastomosis of the medial sural cutaneous nerve and the sural communicating nerve, or it may be found as a continuation of the lateral sural cutaneous nerve [2] traveling parallel to the ...
Dermatome (anatomy) A dermatome is an area of skin that is mainly supplied by afferent nerve fibres from the dorsal root of any given spinal nerve. [1][2] There are 8 cervical nerves (C1 being an exception with no dermatome), 12 thoracic nerves, 5 lumbar nerves and 5 sacral nerves. Each of these nerves relays sensation (including pain) from a ...
The sole and the longitudinal arches of the foot are supported by a thick connective tissue, the plantar fascia. The central component of this tissue extends to the supporting bones and gives two divisions–the medial component and lateral component; thus they define the boundaries of the three muscle compartments of the sole (see below).
The sciatic nerve, also called the ischiadic nerve, is a large nerve in humans and other vertebrate animals. It is the largest branch of the sacral plexus and runs alongside the hip joint and down the lower limb. It is the longest and widest single nerve in the human body, going from the top of the leg to the foot on the posterior aspect.
The lateral cutaneous nerve of the thigh (also called the lateral femoral cutaneous nerve) is a cutaneous nerve of the thigh. It originates from the dorsal divisions of the second and third lumbar nerves from the lumbar plexus. It passes under the inguinal ligament to reach the thigh. It supplies sensation to the skin on the lateral part of the ...
The peripheral nervous system (PNS) is divided into the somatic nervous system, the autonomic nervous system, and the enteric nervous system.However, it is the somatic nervous system, responsible for body movement and the reception of external stimuli, which allows one to understand how cutaneous innervation is made possible by the action of specific sensory fibers located on the skin, as well ...
