Proprioceptive stimuli differ from tactile stimuli in that _.
Correct answer: D. Proprioceptive stimuli are internal and generated by body position and movement, while tactile stimuli are external
- A. Tactile neurons are able to differentiate a range of sensations, while proprioceptive neurons are specific to a particular quantity of force
- B. Tactile stimuli are transmitted through the spinal trigeminal pathway, while proprioceptive stimuli are transmitted through the main sensory trigeminal pathway
- C. Tactile stimuli result in a general sensation, while proprioceptive signals the intensity of the sensation
- D. Proprioceptive stimuli are internal and generated by body position and movement, while tactile stimuli are external
Explanation
The only entirely true statement is that proprioceptive stimuli are internal and generated by body position and movement, while tactile stimuli are external. Proprioception is the awareness of the body in space, which allows animals to have the sensation of the placement of their bodies without needing to see what they are doing or feel their way. Tactile perception is the body's interaction with an external stimulus, such as pain, temperature, or pressure. While most tactile stimuli are transmitted through the spinal trigeminal pathway, certain sensations use the main sensory trigeminal pathway.

About Chemical Coordination and Hormones
Chemical coordination uses hormones released by endocrine glands and carried in blood to specific target cells. Coverage includes the pituitary, thyroid, pancreas, adrenal glands, ovaries and testes, feedback control, and the contrast between slower, longer-lasting hormonal responses and rapid nervous coordination.
