location of the receptors for tactile, thermal, pain sensation and Proprioceptive sensations Flashcards
_____ sensations arise from stimulation of sensory receptors in the skin, mucous
membranes, muscles, tendons, and joints.
Somatic
True/False
The sensory receptors for somatic sensations are widely and evenly distributed over the body.
False
UNEVENLY distributed so that some areas are more sensitive to stimuli than others
(i.e. fingertips, lips, tip of tongue)
Receptors for somatic senses include
Tactile
Thermal
Pain
True/False
Pain receptors are located in virtually all tissues of the body
True
Thermal receptors are located where?
epidermis and dermis
What does tactile receptors sense?
Touch, pressure, vibration, itch and tickle
Most tactile sensation receptors are located where?
skin or subcutaneous tissue
Most tactile sensations are detected by _______
mechanoreceptors
Mechanoreceptors located in the superficial and ______.
deep dermal layers

What temperatures activates warm receptors?
Temperatures between 32 - 48º Celsius
90 - 118ºF
Temperatures as low as _____ and as high as ____ can be detected
50ºF and 118ºF
What temperatures stimulate nociceptors, instead of thermoreceptors, eliciting painful stimulations
Temperatures below 10ºC (50ºF) and above 48ºC (118ºF)
Nociceptors are found in virtually all tissues of the body EXCEPT for where?
brain
What receptors respond to many stimuli, like extreme temperatures, inadequate blood flow to an organ, or excessive stretching of an organ?
Nociceptors
True/False
Nociceptors adapt to pain
False
They do not
________ is known as acute, sharp, or pricking pain, for example, from a needle puncture. This pain is precisely localized.
Fast pain
Pain felt in a surface area far from the stimulated organ is called
referred pain
pain from a heart attack which radiates along the left arm, is what type of pain?
Referred pain
______ is also known as the kinesthetic sense or the perception of body movements.
Proprioception
Proprioceptors provide information concerning what?
movement
Proprioceptors are located where?
skeletal muscles
tendons
in and around synovial joints
in the inner ear
What informs which muscles are contracting
Muscles spindles
What informs of the amount of tension in our tendons
Tendons organs
What informs the position of our joints
while doing work.
Joint kinesthetic
What monitors the orientation of the head relative to the ground and positioning during movements?
Hairs cells in the middle ear
What allows us to estimate the weight of objects and determine the muscular effort needed to perform a task?
Proprioceptive sensations
