PPT-Sensory Receptors (a) Receptor

is afferent neuron b Receptor regulates afferent neuron To CNS Afferent neuron Afferent neuron To CNS Receptor protein Sensory receptor Stimulus Neurotransmitter Sensory receptor. In all sensory receptors the stimulus causes a change in membrane permeability causing a generator potential However many sensory r eceptors photoreceptors cochlear hair cells and vestibular hair cells do not produce action potentials as a result By Poppy and Jake. Intracellular receptors. Where are they?. What binds to them?. Intracellular (duh). Some are in the cytoplasm and some are in the nucleus.. Lipophillic. and hydrophobic ligands. E.g.

A receptor is a protein molecule usually embedded within the cell membrane with part of its structure exposed on the outside of the cell.. The protein surface is a complicated shape containing hollows, ravines, and ridges.. The function of the sensory organ. Detect stimuli or changes in the environment. Pass the impulse to the brain for interpretation then followed by action (respond) if necessary. . Provide the ability to protects us from harm or injury. Sensory systems receive information from the environment via specialized receptors in the periphery and transmit this information through a series of neurons and synaptic relays to the CNS. .
