- 15) Examine the diagram of a reflex arc shown below. In this case, pain from tissue damage to the hand results in a response where muscles move the hand away from the painful stimulus. ST. gridld.doi vd ehow or2 1o notelvib dot Figure 38-10 Biology; Life on Earth, 8/e © 2008 Pearson Prentice Hall, Inc. barostin 20 a) On the diagram above, label the motor neuron, the sensory neuron, the interneuron, and the effector. b) List any way or ways in which the nervous system will determine the intensity of the pain the example above. Corobral cortexPositive feedback loops are used in chemical messaging in the body. Below is a list of steps that describe how a positive feedback system works in chemical messaging. The list is out of order. Placed the list in the proper order. 1. A sensor in a persons finger senses a change in the bloodstream. 2. The chemical messenger triggers the production of a specialized protein in the finger in response to the original signal. 3. A chemical messenger is released from the brain and travels to the finger. 4. As the specialized protein is made in the finger, it triggers the production of even more specialized protein. 5. The brain determines that conditions are no longer in homeostasis.The autonomous nervous system regulates involuntary functions of the body and can be subdivided into the sympathetic and the parasympathetic nervous system. Both of these systems control the same group of body functions, but have opposite effects on the functions they regulate. The sympathetic nervous system prepares the body for intense physical activity like the fight-or-flight response. The parasympathetic nervous system has the opposite effect and relaxes the body and inhibits or slows many high energy functions. Which of the following involuntary effects in the body are brought about by the sympathetic nervous system during a fight-or- flight situation? i. Increased salivation ii. Increased digestion ii. Loss of bowel and bladder control iv. Body shivering Сrying Pupil dilation B. i, iv and v V. vi. A. i, ii and vi C. iii, iv and vi D. iii and v
- If the nervous system finds a particular pathway is inaccessible, it will: Continue to use that pathway to send messages to and from other parts of the body. Try to find or create a new pathway to send the signal to or from other parts of the body. Use the muscles to send a signal without the use of the nervous system. None of the above.The students in Ms. Potter's class are making drawings to represent system models of a mouse. Which of the following best describes what they should draw as the boundary of the system? the circulatory, digestive, or nervous system of a mouse an appropriate environment for a mouse the exterior surfaces of a mouse a mouse and its associated inputs and outputsLidocaine is an anesthetic that is commonly used in medical and dental practices. After being injected or applied to the skin, lidocaine very quickly causes numbness in that area by affecting nerve transmission. Which option below is a possible mechanism by which lidocaine might work? Mimics the neurotransmitter released by sensory neurons Causes an influx of calcium into the axon bulb of sensory neurons Prevents the opening of sodium channels in the sensory neurons
- Your nervous system is organized into two broad anatomical divisions: the central nervous system (consisting of the brain and spinal cord) and the peripheral nervous system (PNS). Your PNS is further organized into two functional divisions. If you tap your knee, the signal to act is carried via your to the muscles in your knee. In contrast, the signals that pass via the are involuntary and act primarily to regulate your body's internal environment. This involuntary nerve system is further organized into three divisions. If you need a sudden burst of energy, your is activated to help you act quickly. In contrast, if you are relaxing and conserving energy, then it is your that is primarily in action. The third division is your which helps control the components of the digestive system.Which of the following statements regarding the functions of the nervous system is/are true? Check all that apply. Check All That Apply The nervous system is an organ system dedicated to control and coordination of body cells. The nervous system communicates via hormones. Sensory nerve endings transmit messages to the spinal cord and brain. The nervous system's major subdivisions are the CNS and PNS. The nervous system responds slowly and relies on the blood stream to carry its neurotransmitters.Which of the following can serve as an "effector" in physiological feedback loops in animals? Group of answer choices a gland brain spinal cord olfactory receptor (smell receptor)
- Which of the following statements is CORRECT in describing the positive feedback control systems in our body? Group of answer choices The response counteracts the stimulus, shutting off the response loop. The response reinforces the stimulus, sending the variable farther from the set-point. The response is able to move the variable closer to the set-point. The response is able to move the variable farther from the set-point by suppressing the stimulus.The amygdalae are almond shaped structures found near the hippocampus in the brain. The amygdalae are responsible for certain emotions such as fear and can trigger changes in the body in response to these emotions.The amygdalae are regulated by the structure of the brain that controls reasoning and critical thinking.The structure of the brain that regulates the amygdalae and the hormone that is released when the amygdalae sense fear are, respectively: Select one: a. Structure Hormone Parietal lobe Cortisol b. Structure Hormone Frontal lobe Cortisol c. Structure Hormone Frontal lobe Epinephrine d. Structure Hormone Parietal lobe EpinephrineAutism is a condition that is generally characterized by difficulties in communicating, understanding abstract concepts, and forming relationships with other people. Recent studies show that children with autism tend to have low levels of oxytocin. Oxytocin nasal spray has been tried as a medical intervention. List two main functions of oxytocin in the body.
