Physiology Quiz 6 05/04/2016 Mixed nerves house: motor neurons only. somatic neurons only. sensory neurons only. both sensory and motor neurons. [AdsenseImage] Which division of the peripheral nervous system (PNS) detects stimuli and carries them to the central nervous system (CNS)? sympathetic motor sensory autonomic Which cranial nerve is NOT involved in eye movement? abducens nerve (VI) trochlear nerve (IV) vestibulocochlear nerve (VIII) oculomotor nerve (III) Which cranial nerve detects smell? olfactory nerve (I) oculomotor nerve (III) optic nerve (II) trochlear nerve (IV) Ms. Parker has damage to the sensory root of the facial nerve (VII). Which of the following symptoms matches this information? inability to taste inability to elevate the mandible inability to smell inability to swallow Loss of balance and equilibrium can indicate damage to the: trochlear nerve (IV). accessory nerve (XI). vestibulocochlear nerve (VIII). hypoglossal nerve (XII). During a boxing match, Sammy was hit on the side of the neck. He stopped breathing temporarily due to damage to the: sacral plexus. lumbar plexus. cervical plexus. brachial plexus. [AdsenseImage] Striking the “funny” bone is actually stimulation (or injury) to the: ulnar nerve. median nerve. radial nerve. axillary nerve. Your wrap your hands around a warm cup of hot chocolate. This sensation is detected by a: hair follicle receptor. chemoreceptor. photoreceptor. thermoreceptor. Regions of skin supplied by a spinal nerve for somatic sensation are known as: lines of cleavage. the ABCDE rule. dermatomes. the rule of nines. Place the following steps in order for motor control. 1. Upper motor neurons stimulate lower motor neurons. 2. Sensory information is relayed back to the cerebellum so movement can be modified if needed. 3. Upper motor neurons in the premotor cortex select a motor program. 4. Lower motor neurons stimulate a skeletal muscle to contract. 5. The basal nuclei enable the thalamus to stimulate upper motor neurons of the primary cortex. 2, 5, 3, 1, 4 3, 5, 1, 2, 4 5, 3, 1, 4, 2 3, 5, 1, 4, 2 In the crossed-extension reflex, if the right leg flexes, then the left leg: extends. abducts. flexes. adducts. As Lisa drove home, she was suddenly alerted to the sound of a blaring horn and realized she had drifted off to sleep. Which nervous system division dominated when she was startled awake? sympathetic nervous system sensory nervous system parasympathetic nervous system somatic nervous system [AdsenseImage] What do the parasympathetic and sympathetic nervous systems share in common? Both systems are called the “rest and digest” division of the autonomic nervous system (ANS). Both systems trigger the same motor response in target organs. Both systems are divisions of the autonomic nervous system. Both systems have short preganglionic neurons and long postganglionic neurons. What neurotransmitter is released by the axon of a sympathetic preganglionic neuron to communicate with the sympathetic postganglionic neuron? norepinephrine acetylcholine epinephrine adrenalin If a drug is administered to block the heart’s adrenergic receptors, how is heart rate affected during exercise? Heart rate will be unable to increase in response to exercise. Heart rate will increase in response to the drug. The drug has no effect on heart rate during exercise. The heart will stop beating. Due to an accident, Lori’s sacral nerves are severed. What do you expect to be affected by this injury? production of saliva blood pressure and heart rate heart and lungs urinary bladder and the last portion of the large intestine Maddie planned to go for a swim after dinner. But, after a large meal, she decided to rest rather than swim. What neurotransmitter promotes rest by binding muscarinic receptors after her meal? epinephrine norepinephrine adrenalin acetylcholine What part of the brain largely controls homeostatic functions? occipital lobe cerebellum hypothalamus pineal gland [AdsenseImage] Which nervous system usually maintains a heart rate of 72 beats per minute? sympathetic nervous system somatic nervous system central nervous system parasympathetic nervous system Unveiling the Mysteries of Mount Diablo 4: Exploring the Enigmatic ConnectionHooked By the Text Phishers As an Amazon Associate we earn from qualifying purchases through some links in our articles.
