(a)
To determine: The condition of a person whose heart rate quickened, and the hairs on the arm have stood due to letting out a scream.
Introduction: The stress or fright conditions are controlled by the sympathetic nervous system of the body.
(b)
To determine: The region of the brain that processes fear.
Introduction: The three main parts of the human brain are the cerebrum, cerebellum, and brainstem. The largest part of the brain is the cerebrum.
To determine: The function of the limbic system of the brain.
Introduction: The limbic system operates by influencing the endocrine system and the autonomic nervous system. The limbic system is a network of structures located under the cerebral cortex.
To determine: The branch of the motor output that controls the limbic system.
Introduction: The limbic system is important because it controls some behaviors that are important to the life of all mammals. The limbic system is the portion of the brain that deals with the functions of emotions, memories, and arousal.
To determine: The target organs for the given response.
Introduction: Target organ refers to a specific organ on which a drug, a hormone, or other substances act.
(c)
To determine: The reason that hair stands on one end, while hair is composed of the proteins that do not contract.
Introduction: Hair is made of a protein known as keratin. Keratin is a tough protein that protects epithelial cells from damage or stress.
To determine: The type of tissue attached to hair follicles.
Introduction: Hair follicle is a part of the skin, which includes sebaceous glands, nerves, and blood vessels.

- Cerebrospinal fluid (CSF) is made by groups of ciliated glial cells called [ Select ] in clumps called (A) [ Select ] which are mostly located in cavities within the brain called (B) ventricles . CSF flows out of those cavities into the (C) ventricular space, which sits deep to the dura mater and is held open by strands of tissue called arachnoid (D) villi . This space surrounds the brain and the spinal cord and carries waste from the CNS to the circulatory system. After circulating around the brain and spinal cord, CSF drains back into the circulatory system in spaces called (E) subarachnoid space .arrow_forwardAlzheimer’s disease is thought to cause a DECREASE in the amount of acetylcholine (ACH) being released into the synaptic cleft in specific parts of the brain. What would be a possible treatment for this disease? (So basically- what would be a possible way to increase the amount of ACH in the synaptic cleft?)arrow_forwardA brain surgeon removed a piece of a woman’s skull and cut through all the meninges to reach the brain itself. Name all the layers that were cut, from skin to brain.arrow_forward
- The den network of fibers that connect the two hemispheres is called the corpus Callosum. Much of what we know about the difference between the left and right hemispheres came from the study of patients with a severe form of epilepsy. To help control the number, duration, and intensity of the epileptic seizures, The corpus callosum was cut. By studying these individuals, Roger Sperry and others learned that the two hemispheres are specialized for different types of task and different modes of thought. Which hemisphere and most people would be better at putting together a puzzle? A. Neither- this is better controlled by the cerebellum B. Both are equally good at this task C. Left D. Rightarrow_forwardEpilepsy is a neurological disorder that disrupts neural activities and causes recurrent seizures. About 70% of people with epilepsy can be treated with medication to prevent seizures from occurring. If medication does not work, surgery is an option for some patients. One of the procedures involves cutting the brain so that the seizures cannot be spread to other parts of the brain. A person with epilepsy had a successful surgery to prevent the spread of epileptic activity between the two hemispheres of the brain. When an object is presented to the left visual fields of both eyes, this person can see the object but cannot verbally describe the object. When the object is presented to the right visual fields of both eyes, this person can see the object and is able to verbally describe the object. a. Describe the visual pathway from left visual fields to perception in the brain. b. Identify the area of the brain responsible for speech production. Include the name of the area, the…arrow_forwardEpilepsy is a neurological disorder that disrupts neural activities and causes recurrent seizures.

- Which area(s) of the brain exert(s) control over the autonomic nervous system? cerebrum cerebellum hypothalamus pons medulla thalamus 1, 2, 3, 5 1, 3, 4, 5 2, 3, 4, 5 1, 3, 5 1, 2, 3, 4, 5, 6arrow_forwardThe ____ and ____ are both found deep within fissures of the cerebral cortex. These two regions form a network with the amygdala and hypothalamus. Although they are also involved in other important functions, many modern imaging studies show that they activate simultaneously during the conscious experience of emotional feelings. A) anterior cingulate cortex; anterior insular cortex B) thalamus; hippocampus C) caudate nucleus; globus pallidus D) substancia nigra; ventra tegmental areaarrow_forwardMost people with Broca’s aphasia suffer from partial paralysis on the right side of the body. Most people with Wernicke’s aphasia do not. Why?arrow_forward
- 34. Elon wants to find a way to prevent visitors to his factory and labs from remembering anything about what they've seen. He asks you to come up with a couple of ways of preventing the formation of declarative memories. Pretend you have no morals whatsoever and can be as invasive as you'd like. Which of the following techniques would be LEAST effective for this goal? a. Administering a CaMKIIa inhibitor on the hippocampus b. Destroying the hippocampus c. Destroying the prefrontal cortex d. Administering a NMDA receptor blocker in the hippocampusarrow_forwardEpilepsy Epilepsy is a neurological disorder that disrupts neural activities and causes recurrent seizures.

An individual was suffering from violent headaches and blurred vision for several years. A doctor determined that this individual had a tumour on the anterior pituitary. Explain why this person was experiencing blurred vision.arrow_forwardJohn Jones, age 33, has been admitted to the hospital for the third time with a diagnosis of paranoid schizophrenia. John had been taking haloperidol (Haldol) but stopped taking it weeks ago, telling his case manager it was “the poison that is making me sick.” Yesterday, John was brought to the hospital after neighbors called the police because he had been up all night yelling loudly in his apartment. Neighbors reported him saying, “I can’t do it! They don’t deserve to die!” and similar statements. John appears guarded and suspicious and has little to say to anyone. His hair is matted, he has a strong body odor, and he is dressed in several layers of heavy clothing even though the weather is warm. So far, John has been refusing any offers of food or fluids. When the nurse approached John with a dose of haloperidol, he said, “Do you want me to die?” What additional assessment data does the nurse need to plan care for John? Identify the three priorities, nursing diagnoses, and expected…arrow_forward
