9. A patient has suffered a spinal cord injury that completely severed the spinal cord at level T2. Identify which of the following will be negatively affected by the paralysis. (Check all that apply.) a. involuntary control of muscles that reduce the amount of light entering the eye b. involuntary control of sphincters that relax to drain urine from the urinary bladder c. release of epinephrine from the adrenal medulla d. voluntary control of both lower limbs 10. Match each of the descriptions in column A with the division of the autonomic nervous system listed in column B. (Answers will be used more than once.) Column A 1. conserves energy and replenishes nutrient stores 2. contains ganglia that are located next to the spinal cord 3. contains ganglia that are close to an effector 4. maintains homeostasis during times of stress or emergency 5. outflow pathways include cranial nerves and pelvic splanchnic nerves 6. preganglionic neurons innervate the adrenal medulla Column B a. parasympathetic division b. sympathetic division

28. Which of the following lists the components of a reflex arc in the correct order of functioning? A) receptor, motor neuron, integrating center, sensory neuron, effector B) motor neuron, receptor, integrating center, sensory neuron, effector C) receptor, sensory neuron, effector, motor neuron, integrating center D) receptor, sensory neuron, integrating center, motor neuron, effector E) effector, sensory neuron, integrating center, motor neuron, receptor 29. Clark has fallen off his horse, and landed on his head. He now can breathe only with the aid of a respirator. This is most likely because he has: A) damaged the spinal cord above the level of C3 B) punctured his lungs via broken vertebrae and ribs C) severed the intercostal nerves innervating the thoracic structures D) crushed the centers in the brain that regulate breathing E) ruptured the upper air passages as his head compressed onto his neck 30. All spinal nerves except the first cervical pair emerge from the spinal cord through the: A) vertebral bodies B) intervertebral foramina C) intervertebral discs D) cauda equina E) filum terminale 31. A misplaced intramuscular injection has rendered a patient unable to abduct his arm. This patient most likely has damage to the: A) axillary nerve B) median nerve C) radial nerve D) ulnar nerve E) phrenic nerve

'Match the concept with the correct section of the nervous system: Central nervous system Consists of the brain and spinal cord Responsible for sending sensory messages to the CNS and sending motor messages to muscles and glands Autonomic nervous system Parasympathetic nervous system 3. Responsible for voluntary control: sense receptors send messages to the CNS and impulses travel from the CNS to effectors (muscles) Peripheral nervous system Sympathetic nervous system Responsible for involuntary control: controls glandular secretions (enzymes and hormones) and the function of smooth and cardiac muscles Somatic nervous system 5. Activated in emergencies and in times of stress 6. Activated when the body is calm, at rest and digesting a meal'

Sympathetic nervous system Parasympathetic nervous system Both Neither 1. : Cell bodies are located in the thoracolumbar region of the spinal cord. 2. : Some preganglionic fibers synapse with the adrenal gland. 3. : The heart is a target. 4. : Cell bodies are located in the brain stem. 5. : Preganglionic fibers are long. 6. : Skeletal muscles are targets.
