Chapter 10, Problem 3CP
Summary Introduction
To review:
The neural pathways from cutaneous pain and pressure receptors to the brain via a diagram and indicate where crossing-over occurs.
Introduction:
The skin has pain receptors in the form of free nerve endings that are sensitive to cuts/injuries and temperature also. Skin also has mechanoreceptors to detect the pressure applied to it. The sensory inputs from the skin are carried out by the neurons to the specific parts of the brain. The human brain has a specific are for the manipulation of sensory inputs from the skin.

Explain the ascending pathway of how the information about touch sensation travels from the right arm up to the brain where he is aware that he has been touched. (Use complete sentences.) Use these key words in this order: sensory neuron, radial nerve in brachial plexus, spinal nerve, dorsal root ganglion, dorsal root, dorsal horn in cervical spinal cord, ascending tract, decussate, somatosensory cortex in postcentral gyrus, parietal lobe, Mr. Dexter thinks “Someone touched my arm.”)
