Final answer:

A sensory receptor is the ending of a sensory nerve and a sensory nerve receives information about the body’s environment; these statements are true.

Step-by-step explanation:

The statements "a sensory receptor is the ending of a sensory nerve" and "a sensory nerve receives information about the body’s environment" are true. Sensory receptors are specialized cells that respond to environmental stimuli, such as temperature, light, touch, and sound. These receptors are often located at the ends of sensory nerves, which transmit the information they receive to the central nervous system (CNS). It is through this process that the brain interprets the signals and formulates a response.

The statement "the central nervous system is another name for the brain" is not accurate. The central nervous system includes both the brain and the spinal cord. While the brain acts as the control center for processing information and coordinating actions, the spinal cord is crucial for transmitting messages between the brain and the rest of the body.

Lastly, the statement "a sensory nerve controls the movement of the body" is incorrect. Movement control is the role of motor nerves, which are part of the sensory-somatic nervous system and transmit instructions from the CNS to the muscles.
