HAP- Sensory receptors

Senses- Sensory receptors

What do all sensory organs contain? 

Sensory receptors—dendrites that react to a certain external or internal stimulus. 

What are sensory receptors? 

Dendrites that react to a certain external or internal stimulus. 

What are the 5 major types of sensory receptors? 

1. Mechanoreceptors (touch) 

2. Thermoreceptors (temperature variations) 

3. Pain receptors (nociceptors) 

4. Chemoreceptors (chemicals) 

5. Photoreceptors (light) 

Do sensory organs contain one or multiple types of receptors? 

Each sensory organ has one or more of these receptors.

What are cutaneous sensations?

The impulses produced in the skin. These sensations include touch, heat, cold, pressure, and pain.

What sensations are included in cutaneous sensations? 

Touch, heat, cold, pressure, and pain.

Are sensory receptors equally distributed throughout the body?

No, they are not equally distributed. Some body parts are more sensitive than others. 

What types of sensations does the skin sense? 

Pain, temperature, touch, and pressure. 

What detects light touch in hairless skin?

Encapsulated nerve endings found in hairless skin. 

What detects light touch and pressure within the epidermis?

Receptors located within the epidermis (general touch/pressure receptors). 

What detects movement of hair?

Receptors associated with hair follicles. 

What detects deep pressure and stretching of the skin?

Encapsulated nerve endings that detect deep pressure and stretching. 

What detects deep pressure and vibrations? 

Encapsulated nerve endings that detect deep pressure and vibrations. 

What is the summary statement for sensory receptors?

Sensory receptors are located throughout the body to respond to stimuli such as touch, temperature, pain, chemicals, and light. The skin receives cutaneous sensations through a variety of receptors spread through the dermis and epidermis.
