Nicotinic receptors are commonly present in the neuromuscular junction (neuromuscular endplate). They respond to acetylcholine released from the terminals of motor neurons by opening to allow deploarizing K+ flow.
They are used in the breathing process of frogs. Their function is similar to that of the rectus abdominus, which compresses the lungs and forces the air out.
This is the scientific name. Rectus means to be upright, Femoris means pertaining to the femur.
Leg muscle means probably the calf muscle, you want to say. Calf muscle is formed by two muscles. They are gastrocnemius muscle and soleus muscle. They have a common tendon. That is tendo calcaneus. Calf muscle move do to stimulation of the nerve supplied to them, that is a tibial nerve. Tibial nerve is a branch of sciatic nerve.
