WebThe acetylcholine receptors in skeletal muscle cells are called nicotinicacetylcholine receptors. They are ion channels that open in response to acetylcholine binding, causing depolarization of the target cell.

WebJan 17, 2024 · proprioreceptor: A sensory receptor that responds to position and movement and that receives internal bodily stimuli. posterior (dorsal) column-medial lemniscus pathway: A sensory pathway of the central nervous system that conveys localized sensations of fine touch, vibration, two-point discrimination, and proprioception from the … WebSomatosensory receptors include senses such as pain, touch, temperature, itch, and stretch. For example, a specific muscle fiber called an intrafusal muscle fiber is a type of afferent neuron that lies parallel to the extrafusal muscle fibers thus functions as a stretch receptor by detecting muscle length.
