The cardiovascular center is responsible for regulatingthe heart and blood vessels through homeostaticmechanisms. What tone does each component of thecardiovascular system have? What connections does thecardiovascular center invoke to keep these two systems intheir resting tone?
Medical practice is paying more attention to theautonomic system in considering disease states. Whywould autonomic tone be important in consideringcardiovascular disease?
why is dual innervation important to organs such as the heart and bronchial tubes.

- Which branch of the autonomic nervous system innervates blood vessels? Which layer of the blood vessel wall do these nerves innervate? What are the effectors (cells that carry out the response)?arrow_forwardCallisto survives the accident and goes to jail. Many years later she is found slumped in her cell, quite confused and with apparent paralysis in her right arm. When the jailer speaks to her, she is unable to produce any clear speech. Callisto can understand very simple sentences, and her sight is not affected. It is determined that she has a vascular occlusion (blockage) in her internal carotid artery. Callisto’s blood pressure is markedly lower than would be expected under physiological conditions. Based on this information, how are these structures in brain affected (if they are). Provide justification. Short answers. 1. Broca's area 2. Right posterior cerebral artery 3. Autonomic nervous systemarrow_forwardWhich of the following statements best describes the structure of the blood-brain barrier that provides its functional characteristics? Group of answer choices Processes of astrocytes wrap tightly around capillaries in the brain Tight junctions tightly seal endothelial cells of capillaries in the brain Gap junctions tightly seal endothelial cells of capillaries in the brain Spot desmosomes tightly link capillary endothelial cells together The basement membrane of the capillaries in the brain contains extremely small poresarrow_forward
- How does the nervous system needs the circulatory system to work? What will happen to the nervous system without the circulatory system?arrow_forwardWhich of the following is stimulated by the Sympathetic nervous system? Question 9 options: Increased dilation of respiratory tubes in lungs during exercise Increased contractions of the digestive system for peristalsis Increased contractions of rectum muscles to defecate Increased saliva and tear production Increased contractions of urinary bladder to urinatearrow_forwardSympathetic tone causes which of the following? decrease in heart rate O activation of the lacrimal gland O increase in urinary tract activity O blood pressure to rise O reflex peristalsisarrow_forward
- What are proprioceptors? Where are the three types found in the body?arrow_forwardWhy would the baroreceptors reflex not compensate for these changes? (select one). O The right heart is not innervated by the autonomic nervous system. Pulmonary vessels are not innervated by the autonomic nervous system. Baroreceptors only monitor arterial pressure in the systemic circulation. Parasympathetic signalling to pulmonary vessels will be equal to sympathetic signalling, therefore there will be no net autonomic effect.arrow_forwardThe spinal cord has the motor neurons that control muscle. But who controls those motor neurons? Neurons in the motor cortex control them. There are also other groups of neurons that can command spinal motoneurons. For example, when it comes to controlling our balance and posture, cells from Ventricular Nucleus descend onto spinal motoneurons to control them. They form a tract within the ventromedial pathway called vestibulospinal trackarrow_forward
- In atropine poisoning, would you expect the pupils to be dilated or constricted? The skin to be moist or dry? The heart rate to be elevated or depressed? The bladder to retain urine or void uncontrollably?arrow_forwardThe sympathetic and parasympathetic nervous systems are very important in maintaining homeostasis in the human body. In your clinic you meet patients with either high blood pressure or low blood pressure. Explain how you will utilize either the sympathetic or parasympathetic systems to treat either a patient with high blood pressure or low blood pressure? (Take a patient with high blood pressure and describe what you will do and take a patient with low blood pressure and describe what you will do).arrow_forwardWhich of the following would not be classified as part of the peripheral nervous system? Cranial nerve, spinal nerve, ganglion, gray ramus, or nerve track Which of the following terms might describe the receptor involved in detecting the pressure on the surface of your leg? exteroceptor mechanoreceptor visceroceptor a and b all of the above The structure of the eye than can change shape to focus light rays on the fovea centralis is the cornea iris vitreous body lens ora serrataarrow_forward
