Pain Receptors
nerves
A tissue becomes a target tissue when it is affected or stimulated by a specific amino acid. The target tissue has the appropriate receptors to make it susceptible to the hormone.
nerves
When beta receptors are stimulated, it decreases the heart rate to treat for low blood pressure.
Mechanoreceptors
Thermoreceptors
Nerve receptors are stimulated during urination. This stimulation occurs when the walls of the bladder contract and the urination reflex is automatically activated.
skin infection
Sensory receptors.
sodium ions enter the postsynaptic neuron.
Pain receptors are bare dendrites that react to a certain type of stimulus. Some pain receptors become activated when extremes of heat or cold cause your skin temperature to rise or fall to dangerous levels. Hope this helps!
