Sensory Receptors + ex
|
formed by dendrites of afferent nurons or by spcialized receptor cells making synapes with afferent neurons
|
receptors ass c eyes, skin, ears, othr surface organs
|
|
|
Sensory Receptors formed by Dendrites of Afferent Neurons - Pro + Ex
|
stimulus causes a change in membrane potential that generates action potential in the axon of the neuron
|
ex: temperature, pain receptors
|
|
|
Sensory Receptors fromed by a cell that synapes with an afferent neuron - Pro + Ex
|
a separate cell stimulus causes a change in membrane potential that releases a neurotransmittter from the cell. th neurotransmitter triggers an action potential in the axon of a nearby afferent neuron
|
ex: mechanoreceptors, photoreceptors, chemorecptors
|
|
|
Sensory Transduction + Ex
|
conversion of a stimulus into a change in membrane po.
|
ex: stimuli ex: light, heat, sound waves, mechanical stress, chemicals
|
|
|
5 Baisic Types of Receptors, + less common receptors
|
mechanoreceptors, photoreceptors, chemorecptors, thermorecptors, nocicptors
|
internal temp, gravity, acceleration, position of muscles n joints, body balance, internal pH, internal concentration of O, CO, Na, CHO
|
|
|
Mechanoreceptors + Ex
|
detect mechanical energy, such as changes in pressure
|
ex: auditory receptors
|
|
|
Photoreceptors + Ex
|
detect the energy of light
|
ex: retina of eyes
|
|
|
Chemoreceptros + Ex
|
detect specific molecules or chemical conditions
|
ex: taste buds
|
|
|
Thermorecptors + Ex
|
detec the flow of heat energy
|
ex: skin
|
|
|
Nociceptors + Ex
|
detect tissue damage or noxious chemicals, registered as pain
|
ex: skin, some internal organs
|
|
|
T/F All Receptors Produce the same kind of response.
|
false. each receptor produces a specific kind of response
|
|
|
|
Explain how Intensity and Extent of a Stimulus is Related to Frequency
|
the stonger the stimulus the more fequent afferent neurons fire action potentials
|
|
