Study Notes
- General senses' receptors are widely distributed throughout the body.
Distribution of Receptors
- Pain that is perceived as superficial, but is caused by an underlying organ is called referred pain.
Classification by Location
- Visceroceptors are located in internal organs.
- Somatic senses enable the detection of touch, temperature, and pain.
Classification by Stimulus Detected
- Intense stimuli resulting in tissue damage activate nociceptors.
- Chemoreceptors are activated by noxious odors.
Sense of Touch
- Receptors responsible for sensing crude and persistent touch are the Ruffini corpuscles.
Classification by Location
- Proprioceptors function in relation to movement and position.
- Proprioceptors can be found in skeletal muscles.
- Free nerve endings respond to all stimuli, except tickling.
Sense of Touch
- Lamellar corpuscles are least numerous in the skin of the back.
- Free nerve endings are found in most body tissues.
Classification by Location
- Proprioceptors function in relation to movement and position.
Classification by Stimulus Detected
- The word "deform" describes the stimulus detected by mechanoreceptors.
Sense of Pain
- Alpha fibers are associated with sharp, localized pain.
- A variant of a Meissner corpuscle called the bulboid corpuscle is also known as a Krause end bulb.
Sense of Touch
- A Meissner corpuscle is an example of an encapsulated nerve ending.
- The two general classes of senses are general and special.
Introduction
- Sensory impulses ending in the brainstem may affect vital sign reflexes.
Receptor Response
- Sensory impulses ending in the brainstem trigger imprecise or crude sensation awareness.
- Sensory impulses ending in the thalamus give specific awareness of a sensation type, location, and intensity.
Distribution of Receptors
- The two-point discrimination test can be used to measure the sensitivity of the skin in various parts of the body.
Classification by Stimulus Detected
- Osmoreceptors are important in stimulating the thirst center.
Sense of Pain
- Slamming a finger in a car door would stimulate acute pain
Sense of Touch
- Krause end bulbs are another name for the bulboid corpuscle
Sense of Touch
- A large mechanoreceptor with thick laminated connective tissue capsules is the Pacinian corpuscle.
- Adaptation refers to a receptor response decreasing over time to a continuous stimulus.
Classification by Location
- Exteroceptors send phasic impulses to the CNS and are located on or near the surface of the body.
Sense of Touch
- Tactile meniscus is another name for the Merkel Disk
Receptor Response
- A receptor potential does not follow the all-or-none law, it is a graded response.
Distribution of Receptors
- Equilibrium is not considered a somatic sense.
Introduction
- General and special are the two general classes of senses
Receptor Response
- Somatic sensory receptors are found in the all of the following: skin, muscles, eyes and ears.
