Summary Introduction
Introduction:
The main function of the spinal cord is to transmit impulses from the brain to the other parts of the body and from the other parts of the body to the brain. Controlling reflex activities is another function performed by the spinal cord. When an involuntary motor response toward an external stimulus takes place, it is known as a reflex action.

- Juliette lost her left thumb in an accident. Now, whenever she pushes her hair off her forehead, she feels as though she is touching her left thumb, which she no longer has. What best explains what has happened in the area of Juliette’s brain that processes sensation in the body to lead to the phantom sensation. Question 5 options: a) Old memories of sensations related to brushing her hair back simply reassert themselves even though the thumb is no longer present b) Sensory neurons from the scar tissue overlying the stump of the amputated thumb have become hypersensitive to touch sensations c) Sensory neurons that received input from the thumb now respond to input from surrounding cells that receive input from the rest of the hand d) Neurons from the left side of the neocortex serving the right thumb have taken over control of the neurons on the right and are activated by the…arrow_forwardAfter getting her finger caught in a drawer, Ruth holds her finger tightly, and this seems to reduce the pain somewhat. Most likely, this works because what?arrow_forwardSelect the statement that explains the neural mechanism underlying the sensation of fast, sharp pain followed by delayed, longer-lasting pain after an injury. a. Fast pain is conducted by mechanoreceptors, whereas delayed pain is conducted by fibers with free nerve endings. b. Fast pain is conducted by free nerve endings in the dermis, whereas delayed pain is conducted by deep nerve endings in the subcutaneous layer. c. The receptive fields differ for the two types of pain sensation such that fast pain fibers have smaller receptive fields than the delayed pain fibers. d. Fast and delayed pain represent the progression of the injury; both are conducted by the same fibers. e. Fast, sharp pain is conducted by myelinated axons, whereas delayed, longer-lasting pain is carried by unmyelinated axons.arrow_forward
- Ozana was born with cataracts, which made her completely blind. When she was 14 years-old she underwent surgery to remove the cataracts, which allowed visual input to be transmitted to her brain for the first time. However, even though the surgery was a success, Ozana’s vision was never fully functional. A) Describe how the features of neural plasticity might help to explain why Ozana’s vision was not restored. B) Propose one factor that might have increased the chance that Ozana would develop the ability to see, and briefly explain why.arrow_forwardWhen you look at a physical object, like a photograph, light waves emanating from the object stimulate receptors in your eye.
