Name the 5 types of sensory receptors.

1. mechanoreceptors 2. thermoreceptors 3. nocioceptors 4. chemoreceptors 5. photic


what are mechnoreceptors and thermoreceptors responsible for?

mechano - responding to mechanical deformation of the receptor or surrounding area (pressure) thermo - changes in temp.


What are nocioceptors and chemoreceptors responsible for?

nocioceptors - noxious stimuli and result in perception of pain. chemoreceptors - respond to chemical substances, and responsible for taste, smell, 02 levels in the blood, CO2 concentration, osmolarity - concentration gradient of body fluids.


what are photic receptors responsible for ?

respond to light within the visible spectrum.


Where are cutaneous receptors located?

in the terminal portion of afferent fiber


stimulation of free free nerve endings results in what?

perception of pain, temperature, touch, pressure, tickle, and itch sensations.


Where are deep sensory receptors located?

muscles, tendons, and joints.


What are deep sensory receptors primarily concerned with?

posture position sense proprioception muscle tone speed & direction of movement


Name the 5 types of deep sensory receptors.

muscle spindle golgi tendon organs free nerve endings pacinian corpuscles joint receptors


what is the roles of the muscle receptors?

monitor changes in muscle length, position and movement sense motor learning



What are the three categories of anteriorlateral spinothalamic tracts and what is each responsible for?

1. Anterior (ventral) spinothalamic tract - sensation of crudely localized touch & pressure. 2. Lateral Spinothalamic tract - pain & temp. 3. Spinoreticular tract - diffuse pain sensations.


What is the dorsal column medial lemniscal pathway responsible for?

trasmission of discriminative sensations recorded from specialized mechanoreceptors?


what type fine gradation of intensity and precise localization on the body surface are mediated by the dorsal column medial lemniscle pathway?

discriminative touch stereognosis tactile pressure barognosis graphesthesia recognition of texture kinesthesia 2-point discrimination proprioception vibration
