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.
This reflex is elicited by lightly stroking or poking the superior and medial (inner) part of the thigh—regardless of the direction of stroke. [1] The normal response is an immediate contraction of the cremaster muscle that pulls up the testicle ipsilaterally (on the same side of the body). The reflex utilizes sensory and motor fibers from ...
It supplies motor innervation to iliopsoas, pectineus, sartorius, and quadriceps; and sensory branches to the anterior thigh, medial lower leg, and posterior foot. [48] The nerves of the sacral plexus pass behind the hip joint to innervate the posterior part of the thigh, most of the lower leg, and the foot. [46]
What are the inner thigh muscles? The inner thigh muscles (A.K.A. your adductors) are key players when it comes to keeping your hips and lower back in a neutral position, which helps prevent the ...
In the thigh, the nerve lies in a groove between iliacus muscle and psoas major muscle, outside the femoral sheath, and lateral to the femoral artery. After a short course of about 4 cm in the thigh, the nerve is divided into anterior and posterior divisions, separated by lateral femoral circumflex artery. The branches are shown below: [1]
the inguinal or groin region between the thigh and the abdomen, the pubic region surrounding the genitals, the femoral region encompassing the thighs, the patellar region encompassing the front of the knee, the crural region encompassing the lower leg, between the knee and ankle, the fibular region encompassing the outside of the lower leg,
The genitofemoral nerve is a mixed branch of the lumbar plexus derived from anterior rami of L1-L2.It splits a genital branch and a femoral branch.It provides sensory innervation to the upper anterior thigh, as well as the skin of the anterior scrotum in males and mons pubis in females.
L2 – On the anterior medial thigh, at the midpoint of a line connecting the midpoint of the inguinal ligament and the medial epicondyle of the femur. L3 – At the medial epicondyle of the femur. L4 – Over the medial malleolus. L5 – On the dorsum of the foot at the third metatarsophalangeal joint. S1 – On the lateral aspect of the ...
