Body is anterior/ ventral motor
Bottom is posterior/ dorsal sensory
True of False
True
Anterior/ Ventral OR Doral rami supplies regions of the trunk & upper (brachial plexus) & lower limbs (lumbosacral plexus)
Anterior/ Ventral Rami
True or False: The ventral horn of the spinal cord contains the cell bodies of motor neurons and the ventral root contains the axons of these motor neurons.
True
True or False: A spinal nerve contains both motor and sensory components.
True
Explanation:
The ventral and dorsal roots combine to form a mixed spinal nerve; thus, a spinal nerve contains both motor and sensory components.
The ventral rami will supply which of the following parts of the body with motor and sensory innervation? Select all that apply
-back
-anterior portion of the trunk
-upper and lower limbs
-face
-anterior portion of the trunk
-upper and lower limbs
Explanation:
The spinal nerve will exit via the intervertebral foramen and immediately divide into a dorsal (posterior) and ventral (anterior) rami.
Dorsal rami: supplies the skin of the back and the deep muscles of the back and the ventral rami supply the anterior and lateral parts of the trunk and the limbs via plexus. The face receives its innervation from cranial nerves.
True or False: A myotome is a unilateral area of skin supplied by a single spinal nerve.
False
A myotome is a unilateral muscle mass receiving innervation from a single spinal nerve. A dermatome is a unilateral area of skin supplied by a single spinal nerve.
True of False: Sympathetic division (thoracolumbar)- “fight of flight”
Parasympathetic (craniosacral) division- “rest & digest”
True
True or False: Pulmonary is on the right side (DE-oxygenated) heart to lungs
Systemic is on the left side of heart- pumps oxygenated blood to heart
True
If your patient is experiencing bradycardia, what do you know about their heart rate?
It is below 60 beats per minute
Which of the following structures form the pump for the pulmonary circulation?
Select all that apply.
