Hello! I figured the question was missing its options, so I went online to find them. Here is the complete question:
Which of the following functions is NOT associated with the spinal cord?
a) The spinal cord is a major integration center for reflexes.
b) It provides a two-way conduction pathway for signals between the body and the brain.
c) Through the cranial nerves that attach to it, the spinal cord is involved in sensory and motor innervation of the head and neck.
d) Through the spinal nerves that attach to it, the spinal cord is involved in sensory and motor innervation of the entire body inferior to the head.
e) All of the statements are functions attributed to the spinal cord. There are no exceptions.
Answer:
The correct answer is:
C) Through the cranial nerves that attach to it, the spinal cord is involved in sensory and motor innervation of the head and neck.
Explanation:
The only function given in the options that is not associated with the spinal cord is <em>C)</em> because cranial nerves are not attached to the spine, but to the cranium. Cranial nerves DO, however, control head and neck innervation.
Spinal nerves innervate the limbs: the cervical spinal nerves form the brachial plexus to give sensory and motor innervation to the upper limbs, while the lumbar spinal nerves form the lumbar plexus to innervate the lower limbs.
To start, move the objective lens to its lowest power setting. Place a slide on the stage with the label side up and the cover slip in the middle. You can only use the coarse focus knob when the power is low. If you can't see anything, move the slide a little while you look and focus. If nothing shows up, turn down the light and move the slide a little while you're looking and focusing. Once you're in focus on low power, move the slide to make the object of interest in the middle of it. Turn the objective to medium power and only change the fine focus. If you need to, turn the objective to high power and only adjust the fine focus.
