Anatomy & Physiology 2 - Chapter 14: Spinal Cord
and Spinal Nerves questions with verified answers
Define Intervertebral forearm Ans✓✓✓A lateral opening between two
adjacent vertebrae.
Define vertebral canal Ans✓✓✓Stacked vertebral foramina.
Define vertebral column Ans✓✓✓The boney framework that houses
the spinal cord.
Describe the location of the spinal cord meninges. Ans✓✓✓1. Pia
mater - adheres to the external surface of the spinal cord
2. Arachnoid mater - lies external to the pia mater
3. Dura mater - the outer layer of the meniges
How do sensory and motor pathways differ from each other?
Ans✓✓✓Sensory pathways pass information from a stimulus up into
our brain and motor pathways pass information from our brain into our
body.
How many spinal nerves are associated with the spinal cord?
Ans✓✓✓There are 31 spinal nerves associated with the spinal cord: 8
cervical nerves (C1-C8), 12 thoracic nerves (T1-T12), 5 lumbar nerves
(L1-L5), 5 sacral nerves (S1-S5), and 1 coccygeal nerve (Co1).
, There are two subdivisions of general sense receptors, what are they?
Ans✓✓✓1. Somatic sensory receptors - these tactile receptors that
monitor the characteristics of an object.
2. Visceral sensory receptors - these types of receptors detect a change to
an organ and/or a blood vessel.
What are conduction pathways? Ans✓✓✓Conduction pathways refer to
all of the series of neurons that relay signals between the brain and the
body.
What are dermatomes? Ans✓✓✓Dermatomes are segments of the skin
supplied by signal spinal nerve. These segments help localize damage to
one or more spinal nerve.
What are motor pathways? Ans✓✓✓These are a series of motor
neurons that relay motor output from the brain.
What are nerve plexuses and identify the four main groups? Ans✓✓✓A
nerve plexus is a network of interweaving anterior rami of spinal nerves.
The four main plexus are: (1) cervical, (2) brachial, (3) lumbar, and (4)
sacral plexus
What are sensory pathways? Ans✓✓✓These are a series of sensory
neurons that relay sensor input to the brain.
What are spinal reflexes? Ans✓✓✓These are the quickest reactions to
stimuli.
