Sensory nerve endings are also known as __________ and are located near the skin's surface.

Neurons
Receptors
Muscles
Axons

The correct answer is: Receptors

Sensory nerve endings are referred to as receptors because they are specialized structures that detect stimuli from the environment, such as touch, temperature, pain, and pressure. These receptors are located near the skin's surface, allowing them to respond to external sensations effectively. They play a crucial role in transmitting sensory information to the nervous system, where the brain can interpret these signals. Neurons are the fundamental units of the nervous system that transmit information but are a broader category that includes different types of nerve cells, not specifically sensory receptors. Muscles are responsible for movement and are separate from the sensory functions of the skin. Axons are the long projections of neurons that carry nerve impulses away from the cell body, but they do not directly refer to sensory nerve endings. This understanding highlights the specific function and location of receptors as key components in sensory perception.
