- In the ___, neurons are arranged like maps that correspond to different parts of the body surface. a. retina b. somatosensory cortex c. basilar membrane d. occipital lobearrow_forwardWatch this animation (http://openstaxcollege.org/l/braindevel) to examine the development of the brain, starting with the neural tube. As the anterior end of the neural tube develops, it enlarges into the primary vesicles that establish the forebrain, midbrain, and hindbrain. Those structures continue to develop throughout the rest of embryonic development and into adolescence. They are the basis of the structure of the fully developed adult brain. How would you describe the difference in the relative sizes of the three regions of the brain when comparing the early (25th embryonic day) brain and the adult brain?arrow_forwardTest your Understanding Know and Comprehend 1. A sensory receptor absorbs energy from some stimulus. The next step is (a) release of neurotransmitter (b) transmission of an action potential (c) energy transduction (d) transmission of a receptor potential (e) sensory adaptationarrow_forward

Summing incoming neural signals is part of (a) reception (b) transmission (c) integration (d) action by effectors (e) afferent neuron transmissionarrow_forwardCompared with the nearest evolutionary relative, the chimpanzee, the human has a brain that is huge. At a point in the past, a common ancestor gave rise to the two species of humans and chimpanzees. That evolutionary history is long and is still an area of intense study. But something happened to increase the size of the human brain relative to the chimpanzee. Read this article (http://openstaxcollege.org/l/hugebrain) in which the author explores the current understanding of why this happened. According to one hypothesis about the expansion of brain size, what tissue might have been sacrificed so energy was available to grow our larger brain? Based on what you know about that tissue and nervous tissue, why would there be a trade-off between them in terms of energy use?arrow_forwardWatch this video (http://openstaxcollege.org/l/whitematter) to learn about the white matter in the cerebrum that develops during childhood and adolescence. This is a composite of MRI images taken of the brains of people from 5 years of age through 20 years of age, demonstrating how the cerebrum changes. As the color changes to blue, the ratio of gray matter to white matter changes. The caption for the video describes it as less gray matter, which is another way of saying more white matter. If the brain does not finish developing until approximately 20 years of age, can teenagers be held responsible for behaving badly?arrow_forward
- Read this article (http://openstaxcollege.org/l/3word) to learn about a young man who texts his fiancée in a panic as he finds that he is having trouble remembering things. At the hospital, a neurologist administers the mental status exam, which is mostly normal except for the three-word recall test. The young man could not recall them even 30 seconds after hearing them and repeating them back to the doctor. An undiscovered mass in the mediastinum region was found to be Hodgkins lymphoma, a type of cancer that affects the immune system and likely caused antibodies to attack the nervous system. The patient eventually regained his ability to remember, though the events in the hospital were always elusive. Considering that the effects on memory were temporary, but resulted in the loss of the specific events of the hospital stay, what regions of the brain were likely to have been affected by the antibodies and what type of memory does that represent?arrow_forwardMatch each item with its description. ___ gray matter a. start of brain, spinal cord ___ neurotransmitter b. connects the hemispheres ___ pons c. protects brain and spinal ___ corpus callosum cord from some toxins ___ cerebral cortex d. type of signaling molecule ___ neural tube e. brain's myelin makers ___ oligodendrocytes f. brain stem structure ___ blood-brain g. controls language, reasoning barrier h. cell bodies and dendritesarrow_forwardWatch this video (http://openstaxcollege.org/l/lumbarpuncture) that describes the procedure known as the lumbar puncture, a medical procedure used to sample the CSF. Because of the anatomy of the CNS, it is a relative safe location to insert a needle. Why is the lumbar puncture performed in the lower lumbar area of the vertebral column?arrow_forward
- 1. Make a model or draw 3 multipolar neurons. Imagine you had something crawling on your arm. The first is a sensory neuron, getting its information from the skin and sensing the movement. The second is an interneuron. It relays information from the first (sensory neuron) to the CNS. The third is a motor neuron. It begins in the CNS but leads all the way to the muscle, so that you can move the fingers and scratch the area. On your images/model the "dendrites" should be blue, "axon" should be green and "soma" should be yellow. As you connect them to each other, take notice in which areas are the receiving end, and which are the transmissive ends.arrow_forwardInstructions: Count the number of cells for each half brain (left and right) and multiply by 2 to estimate volume for the entire brain.
