Chapter 15, Problem 3TYC
Summary Introduction
To determine:
The consequence of transection of pyramids of the anterior side of the medulla oblongata and the gracile and cuneate fasciculi on the posterior side.
Introduction:
The nervous system maintains the coordination by the means of electrical and chemical signals that are transferred from one nerve cell to another nerve cell. The nervous system is majorly divided into the central nervous system (CNS) and the peripheral nervous system (PNS). Nerve cell is the functional unit of the nervous system.

Subcortical structures in humans are quite similar to corresponding brain areas in most animals with spinal cords. Why would knowing this allow you to predict, in general terms, what functions the subcortex controls?
Let’s examine a neural pathway that involved three (3) neurons in sequence: one propagates an action potential from threshold stimulus of receptor to spinal cord; second propagates action potential superiorly to brain stem; and third propagates action potential from brain stem to part of cerebral cortex involved in perceiving the stimulus. Which of the following is correct classification of these neurons:
a. all three are presynaptic
b. first is presynaptic, other two are postsynaptic
c. first and second are presynaptic, third is postsynaptic
d. first and second are presynaptic, second and third are postsynaptic
e. all three are postsynaptic
Scientists are experimenting with new technologies that
could help people with missing limbs. In one investigation,
electrodes implanted in the nervous tissue of a monkey
were connected to an artificial hand. The monkey's nervous
system was able to direct the artificial hand to move. The
below image shows the monkey raising a piece of zucchini
to its mouth using the thought-controlled robotic are (A).
a. Using a flowchart, illustrate the basic neural pathway
from the sensory stimulus to the motor output.
b. What are some other potential applications for this
technology?
c. Do the benefits to human life justify this form of
animal research?

The femoral nerve emerges directly from a single spinal nerve 5. the knee-jerk reflex is considered a cranial reflex 6. reflexes only involve skeletal muscle and not smooth muscle. 7. structures that can be involved in a spinal reflex include a sensory neuron, motor neuron, and an interneuron 8. the crossed-extensor reflex is classified as a monosynaptic reflexarrow_forwardThe figure shown is a homunculus of the star-nosed mole.

Which of the following statements are incorrect? * (A) Cortical magnification in star-nosed mole Dorsal Anatomical proportions 11 11 Mouth Ventral Proportion of cortex devoted to body regions This homunculus depicts that vibrissae take up a huge proportion of association and motor cortex. The larger the cortical area involved, the more sensitive the body region is. There is a high proportion of peripheral sensory neurons in the whiskers of rats and cats. Smaller receptive fields on the skin will give a larger two-point discrimination distance.arrow_forwardInfants have a reflex called sucking reflex.
