Visceral receptors
Mucosal receptors or Epithelial receptors
Mucosal receptors or Epithelial receptors are located immediately below the mucosal epithelium. These are well distributed in the stomach and small intestine. They are rapidly adapting mechanoceptors, but are slowly adapting to chemical stimuli.
Tension receptors
Tension receptors are located within the stomach, small intestine of cats, sheep’s rumen and urinary bladder. These are slowly adapting mechanoceptors and they monitor the distention of the above mentioned structures.
Serosal receptors
Serosal receptors are located under the serosa or in the mesentry. They are slowly adapting mechanoceptors. They monitor visceral filling and distortion in the shape.
