Question
Chapter 14.1, Problem 5AYP
Summary Introduction
To determine:
The functions of the anterolateral and dorsal column / medial lemniscal systems. Also, determine the crossing over and synapse of these two neurons.
Introduction:
The anterolateral system consists of two different tracts that are anterior spinothalamic tract and spinothalamic tract. The dorsal column medial lemniscus pathway is the sensory pathway of the central nervous system.

What determines the dorso-ventral axis of the vertebrate spinal cord and what are the signals that control this dorsal-ventral polarity?
Sensory fibers, or pathways, are referred to as “afferent.” Motor fibers, or pathways, are referred to as “efferent.” What can you infer about the meaning of these two terms (afferent and efferent) in a structural or anatomical context?
Inhibitory interneurons associated with the reflex arc are turned on by glutamate.
Group of answer choices
True
False
The tendon tap reflex can be elicited by a stretch in a muscle. What is the order of information flow from the primary sensory afferent to the lower motor neuron?
Group of answer choices
dorsal horn, dorsal root, ventral horn
dorsal root, dorsal horn, ventral horn
ventral root, ventral horn, dorsal horn, dorsal root
In regards to the spinothalamic tract, where does the second order neuron cross midline?
Group of answer choices
at the spinal cord segment
at the brainstem
at the thalamus
it never crosses midline

- 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_forwardThere are three basic levels of somatic motor control: reflexes, subconscious control, and conscious control. Review these three levels of control by answering the questions below: 1. Which process is the fastest? 2. Which process is the slowest? 3. Which process is the simplest (has the fewest synapses)? 4. Which process is the most complex? 5. Which process are you aware of? 6. A decision made by nuclei in the brain, but not the spinal cord, is which process? 7. A decision made by the spinal cord is which process 8. A decision made by the cerebral cortex is which process?arrow_forwardThree-year-old Jessica proudly shows you how she can wiggle her left big toe in the sand.
