MSN570 WEEK 4 CASE STUDY GUIDE AND
COMPLETE SOLUTION
A 28 year old male presents with opioid dependency. He is not in
treatment at the present time,, and is exhibiting severe withdrawal
symptoms.
1. Compare and contrast the efferent and afferent nerve pathways.
Depending on the direction of the signal, neural impulses can be divided
into 2: Due to each of their function, nerve fibers that carry afferent
impulses are known as afferent nerves, or sensory nerves, and those
nerve fibers that carry efferent impulses are known as efferent nerves or
motor nerves (Gautam, 2017).
Afferent neurons- also called sensory neurons- send information about a
stimulus to the central nervous system (CNS) for further processing and
analysis (Griton & Konsman, 2018). These sensory neurons carry nerve
impulses from sensory stimuli toward the CNS and brain- like sensory
data. For example, a afferent neuron on a nerve ending will detect and
respond to excess heat.
, Efferent nerve pathways function as motor neurons carrying neural
impulses away from the CNS and towards muscles to cause movement
(Gautam, 2017). Efferent neurons send signals from the brain to the
muscles, glands and the peripheral nervous system in response to
sensory input.
2. What is nociception? Nociception is a subdivision of the
somatosensory system within the sensory nervous system; it can be
defined as the neural processes of encoding and processing
noxious stimuli (Physiopedia, 2021).Nociception involves a signal
reaching the central nervous system as an outcome of the
stimulation of unique sensory receptors in the peripheral nervous
system called nociceptors. Nociceptors are ignited by noxious
stimuli and nociception is the physiological process of the body
tissues being sheltered from damage (ScienceDirect, 2021).
Nociception is important in the "fight or flight response" and
protects us from injury. Nociceptors can be activated by three
types of stimulus; temperature (thermal), chemical (pH change
related to
