What are the five different sensory receptors and what
do they do? - .....ANSWER ...✔✔ Mechanoreceptors:
In charge of sound and motion
Electromagnetic receptor: light and electricity
chemoreceptor: taste and smell
Thermoreceptor: heat and cold
Pain receptor: noxiuos chemicals and temparatures
What are the two forms of motor output - .....ANSWER
...✔✔ Glands and muscles
chnages in membrane potential will lead to what? -
.....ANSWER ...✔✔ Action potential
What is sensory reception - .....ANSWER ...✔✔ the
beginning of a pathway, and it is the detection of a
stimulus byspecialized sensory cells.
,2|Page
Neuronal receptors - .....ANSWER ...✔✔ receptor is
afferent neuron
non-neuronal receptors - .....ANSWER ...✔✔ receptor
regulates afferent neuron
- does not itself generate action potentials, but instead
conveys information to an afferent neuron via a chemical
synapse.
sensory transduction - .....ANSWER ...✔✔ the process
in which a receptor cell converts the energy in a stimulus
into a change in the electrical potential across its
membrane
receptor potential - .....ANSWER ...✔✔ change in
membrane potential
Sensory information travels through the nervous system
as - .....ANSWER ...✔✔ Action potential
perception - .....ANSWER ...✔✔ are the brain's
construction of stimuli
,3|Page
The brain distinguishes stimuli from different receptors -
.....ANSWER ...✔✔ by the area in the brain where the
action potentials arrive
do Stimuli from different sensory receptors travel as
action potentials along different or the same neural
pathways? - .....ANSWER ...✔✔ different
Mechanoreceptor - .....ANSWER ...✔✔ Sense physical
deformation
what is Chemoreceptors, and two types - .....ANSWER

1. transmit information about overall solute concentration
2. respond to specific molecules in body fluids, including
glucose, oxygen, carbon dioxide, and amino acids
Electromagnetic receptor - .....ANSWER ...✔✔ detects
electromagnetic radiation, such as light
What is an example of electromagnetic receptor -
.....ANSWER ...✔✔ Photoreceptors
, 4|Page
What are thermoreceptors and where they are located
- .....ANSWER ...✔✔ detect heat and cold

particles - .....ANSWER ...✔✔ mechanoreceptor
statocysts - .....ANSWER ...✔✔ cells that sense gravity
in a cnidarian
statoliths - .....ANSWER ...✔✔ mechanoreceptors in
the Statocysts that detect the movement of granules
what organ enables hearing and balance - .....ANSWER
...✔✔ The Ear
how does the ear works, Generally? - .....ANSWER
...✔✔ It converts airborne sound waves into nerve
impulses that are decoded by the brain
