Sensory Receptors and Their Functions

The video tutorial explores the concept of sensation, distinguishing between general and special senses. It explains how sensory receptors are classified by stimulus type, location, and complexity. The tutorial also covers sensory adaptation, highlighting how certain receptors adapt quickly to stimuli while others, like nociceptors and proprioceptors, do not adapt to protect the body from harm.

What is the primary function of general senses?

• Detecting light

• Balancing the body

• Picking up tactile sensations

• Sensing chemical changes

Which of the following is NOT a special sense?

• Vision

• Hearing

• Touch

• Taste

Chemoreceptors are primarily responsive to what type of stimuli?

• Light

• Temperature

• Dissolved chemicals

• Pressure

What type of receptor is responsible for detecting pain?

• Thermoreceptors

• Mechanoreceptors

• Nociceptors

• Photoreceptors

Where are photoreceptors located in the body?

• Skin

• Tongue

• Eye

• Stomach

What term is used for receptors located deep within organs?

• Mechanoreceptors

• Exterior receptors

• Photoreceptors

• Enteroreceptors

Which receptors are described as having a simple structure?

• Chemoreceptors

• Meissner's corpuscles

• Photoreceptors

• Nociceptors

What is the purpose of sensory adaptation?

• To improve balance

• To enhance sensory overload

• To ignore unimportant stimuli

• To increase pain sensitivity

Which type of receptor does NOT adapt to stimuli?

• Thermoreceptors

• Nociceptors

• Photoreceptors

• Chemoreceptors

Proprioceptors are a type of which receptor?

• Chemoreceptor

• Photoreceptor

• Mechanoreceptor

• Thermoreceptor
