Lecture: Somatic Senses Flashcards
Give an example of a rapidly adapting stimulus
Touch, smell, pressure
This sensory receptor detects mechanical pressure such as touch, pressure, and vibration
Mechanoreceptors
This sensory receptor detects light that strikes the retina of the eye
Photoreceptors
Speaking of the eye, which type of photoreceptor responds to bright light?
Cones
This sensory receptor detects chemical changes in the mouth
Chemoreceptors
This sensory receptor responds to painful stimuli
Nociceptors
This sensory receptor responds to temperature
Thermoreceptors
This is a sensation that allows us to know where our head and limbs are without using our eyes
Proprioception/Proprioceptive sensation
If fast pain is localized (in one area only), then referred pain is?
Localized pain but will diffuse overtime
Where are olfactory responses generated?
Olfactory cilia
Which is more sensitive smell or taste?
Smell
These provide electrical insulation and support for the olfactory receptor cells
Supporting cells
This layer of the eyeball has many blood vessels that nourish the retina
Vascular tunic
This is the outer coat of the eyeball and has the cornea and sclera
Fibrous tunic
What gland is responsible for making tears?
Lacrimal glands
These fibers hold the lens in position and attach them to the ciliary muscles
Zonular fibers
This is found in the anterior cavity of the eyeball and helps maintain eyeball shape
Aqueous humor
Where are the cones concentrated?
Fovea centralis
It is a term for the normal eye with no defects
Emmetropic eye
