What does Umami taste like?
sour
sweet
bitter
savory or meaty
Where are exteroreceptors located?
on or near body surface
internally, often within body organ, or viscera
limited to skeletal muscle, joint capsule and tendons
Umami is believed to arise from taste receptors that are stimulated by (a)
Where are visceroreceptors located?
on or near body surface
internally, often within body organ, or viscera
limited to skeletal muscle, joint capsule and tendons
Where are proprioceptors (a special type of visceroreceptor) located?
on or near body surface
internally, often within body organ, or viscera
limited to skeletal muscle, joint capsule and tendons
Mechanoreceptors: What stimulus is detected?
activated by amount or changing concentration of certain chemicals (e.g., taste and smell)
activated when “deformed” to generate receptor potential
activated by changes in temperature
activated by intense stimuli that may damage tissue; sensation produced in pain
found only in the eye; respond to light stimuli if the intensity is great enough to generate a receptor potential
Chemoreceptors: What stimulus is detected?
activated by amount or changing concentration of certain chemicals (e.g., taste and smell)
activated by changes in temperature
activated by intense stimuli that may damage tissue; sensation produced in pain
found only in the eye; respond to light stimuli if the intensity is great enough to generate a receptor potential
concentrated in the hypothalamus; activated by changes in concentration of electrolytes (osmolarity) in extracellular fluids
Thermoreceptors: What stimulus is detected?
activated by amount or changing concentration of certain chemicals (e.g., taste and smell)
activated by changes in temperature
activated by intense stimuli that may damage tissue; sensation produced in pain
found only in the eye; respond to light stimuli if the intensity is great enough to generate a receptor potential
concentrated in the hypothalamus; activated by changes in concentration of electrolytes (osmolarity) in extracellular fluids
Nociceptors: What stimulus is detected?
activated by amount or changing concentration of certain chemicals (e.g., taste and smell)

Which region of the ear uses air to collect and channel sound waves?
(a)
Which region of the ear uses a bony system to amplify sound vibrations?
(a)
Which region of the ear generates action potentials to transmit sound and balance information to the brain?
(a)
MUST KNOW: Pathway of a Sound Wave
What type of receptors operate to provide body with information concerning muscle length and strength of muscle contraction?
(a)
What are the two types of stretch receptors?
(a)
Which stretch receptor is composed of fibers lying between and parallel to regular muscle fibers
-detect dynamic and static changes in muscle length
-stretch reflex-stretch on muscle causes reflex contraction
-stimulated if the length of a muscle exceeds a certain limit, a stretch reflex is initiated to shorten the muscle, thus helping maintain posture and body position (unconscious)
Muscle spindles
Golgi tendons
Which stretch receptor prevent muscle injury from excessive strain; located at junction between muscle tissue and tendon
-stimulated by excessive stretch of a tendon caused by excessive contraction of a muscle; when stimulated, they cause muscle to relax
Muscle spindles
Golgi tendons
