Carbon 14 has a half life of 5,730 years. Scientists measure how much carbon 14 the rock has. For objects older than 50,000 years, scientists will test the age of the things surrounding it.
Interneuron, skeletal muscle, somatic receptor, afferent nerve fiber, and efferent nerve fiber.
The action potential from skin receptors is sent by nerves in this type of reflex system.
Sensory neurons advance the motion to the Central Nervous System (CNS).
The efferent neuron or motor neuron causes changes at the effector, which are the skeletal muscles, for adequate integration and responsiveness.
Reflex action refers to the full series of actions. The reflex arc is the name of the route.
Somatic receptor followed by afferent nerve fiber, interneurons, efferent nerve fiber, and skeletal muscle constitutes the proper order.
