A point on the skin where pressure or stimulation leads to the contraction of underlying muscle is accurately referred to as a motor point. Motor points are specific locations where nerves enter the muscle, making them particularly responsive to pressure or electrical stimulation. When stimulated, these areas can evoke a response, such as muscle contraction, due to the direct connection to the motor nerve that innervates the muscle.

This concept is essential in practices like massage therapy and acupuncture, where targeting motor points can help relieve muscle tension, improve circulation, or enhance muscle performance. While other terms such as "pressure point," "trigger point," and "acupressure point" refer to areas of the body related to pain relief and muscle tension, they do not specifically denote the direct connection to muscle contraction that motor points do.
