Multiple Choice
A fish detects vibrations in the water around it by means of its lateral lines, rows of sensory receptors along each side of the body. Based on what you know about sensory receptors, the lateral line receptors are probably which of the following?
A
Electromagnetic receptors
B
Chemoreceptors
C
Osmoreceptors
D
Nociceptors
E
Mechanoreceptors
Verified step by step guidance
1
Understand the function of the lateral line in fish: The lateral line system in fish is used to detect movements and vibrations in the surrounding water, which helps them sense their environment and navigate effectively.
Identify the type of sensory receptor involved: Sensory receptors are specialized cells that respond to specific types of stimuli. In this case, the stimulus is mechanical vibrations in the water.
Review the types of sensory receptors: Electromagnetic receptors detect light and electromagnetic fields, chemoreceptors respond to chemical stimuli, osmoreceptors detect changes in osmotic pressure, and nociceptors respond to pain. Mechanoreceptors, on the other hand, respond to mechanical pressure or distortion.
Match the function to the receptor type: Since the lateral line detects mechanical vibrations, the receptors involved are mechanoreceptors, which are specialized for sensing mechanical changes in the environment.
Conclude that the lateral line receptors in fish are mechanoreceptors, as they are responsible for detecting mechanical vibrations in the water.
