Summary Introduction
To review:
The various somatic and visceral sensory and motor inputs as well as outputs.
Introduction:
The peripheral nervous system (PNS) has two branches called somatic and visceral nervous system. The body regions that are regulated by the somatic branch are located outside the ventral body cavity, whereas the visceral branch controls the body structures located in the viscera that is present inside the ventral body cavity.

Give the meaning of the statement, “The idea that all sense organs behave as biological transducers is a unifying concept in sensory physiology.”
My question is
We have learned about the somatotopic, tonotopic, and retinotopic organization that resides within the somatosensory, auditory, and visual cortices, respectively. Briefly describe why this type of organization is important for sensory systems. What are the advantages?
Somatic sensory and somatic motor information are propagated via specialized
neurons. If you dip your toes in a hot tub before entering the tub, the action
potentials generated by the water temperature travels via which of the following
structures before it can be perceived by you?
O unipolar neurons from the toes to the spinal nerve, ventral root, spinal cord, thalamus,
primary somatosensory cortex
O unipolar neurons from the toes to the spinal nerve, dorsal root, spinal cord, thalamus,
primary somatosensory cortex
O multipolar neurons from the toes to the spinal nerve, ventral root, spinal cord,
thalamus, primary somatosensory cortex
O multipolar neurons from the toes to the spinal nerves, dorsal root, spinal cord,
thalamus, primary somatosensory cortex

- You are observing in a Physical Therapy clinic and a patient presents with back pain. The images suggest that they have a disc herniation at the disk between L3 and L4. The PT you are working with believes that the disk is putting pressure on the spinal nerve that contains the afferent and efferent neurons that control the patellar tendon reflex. Using the appropriate anatomy and physiology, describe the afferent and efferent portions of this stretch reflex pathway, including a description of the receptor and what it responds to. If you performed a patellar tendon reflex, describe whether you would expect to see an enhanced or diminished response and explain why.arrow_forwardSin Young incorrectly classified proprioception as general somatic motor because it refers to the innervation of muscles. Actually, proprioception is general somatic sensory. Explain why.arrow_forwardA neurosurgeon probes a person’s brain to map its functions. The person is awake and feels no pain during this procedure. As each area of the brain is probed, the person perceives a different sensation, as described in the table. Which structure (or lobe) of the brain is being stimulated in each scenario?

Alpha motor neurons in the ventral horn are mapped according to muscle location, while cortical motor neurons are organized into purposeful movement groups. b. None of the answers. c. Alpha motor neurons in the ventral horn have a different segment-to-segment organization, while cortical motor neurons are mapped similarly to the somatosensory system. d. Alpha motor neurons in the ventral horn do not have a clear organization, while cortical motor neurons are mapped according to muscle location. e. Alpha motor neurons in the ventral horn are organized into complex movement groups, while cortical motor neurons have no clear organization.arrow_forwardMultiple sclerosis is a demyelinating disease affecting the central nervous system. What type of cell would be the most likely target of this disease? Why? Which type of neuron, based on its shape, is best suited for relaying information directly from one neuron to another?
