Front

What are sensory receptors?

Back

Sensory receptors are specialized cells that detect and respond to external stimuli, such as light, sound, and touch, and are found in sensory organs like the eyes, ears, and skin.

Front

What is the difference between external and internal stimuli?

Back

External stimuli are environmental factors that affect an organism, such as light and sound, while internal stimuli are signals from within the body, such as hunger and thirst.

Front

What is a mechanoreceptor?

Back

A mechanoreceptor is a type of sensory receptor that responds to mechanical pressure or distortion, such as touch and pressure.

Front

What is an example of internal stimuli?

Back

Feeling hungry or thirsty is an example of internal stimuli.

Front

What is a baroreceptor?

Back

A baroreceptor is a type of mechanoreceptor that detects changes in blood pressure.

Front

What is a nociceptor?

Back

A nociceptor is a sensory receptor that responds to potentially damaging stimuli by sending signals that are perceived as pain.

Front

What is a chemoreceptor?

Back

A chemoreceptor is a sensory receptor that responds to chemical stimuli, such as taste and smell.

Front

What is a photoreceptor?

Back

A photoreceptor is a sensory receptor that responds to light, primarily found in the retina of the eye.

Front

What is the function of sensory organs?

Back

Sensory organs are specialized structures that house sensory receptors and are responsible for processing specific types of stimuli.

Front

How do sensory receptors contribute to coordination and response?

Back

Sensory receptors detect stimuli and send signals to the nervous system, which processes the information and coordinates an appropriate response.
