chapter 15: nervous system: autonomic nervous system

autonomic nervous system
involuntary activities of the body, such as changes in blood vessel diameter to adjust blood pressure, are under the control of the:

which cranial nerves are associated with the parasympathetic division of the autonomic nervous system?

parasympathetic and sympathetic
the subdivisions of the autonomic nervous system are the ________ division and ______ division

sympathetic division
which division of the autonomic nervous system is also known as the thoracolumbar division?

large intestine, rectum, urinary bladder, distal parts of the ureters, and most of he reproductive organs
which organs receive postganglionic axons from the inferior mesenteric ganglion?

conscious
the autonomic and somatic nervous system can be distinguished by whether or not we are _______ of the processes they control

facial nerve (CN VII)
which cranial nerves provides parasymathetic innervation to control the production and secretion of tears, nasal secretions, and saliva?

stomach, spleen, liver, gallbladder, and proximal part of the duodenum and part of the pancreas
which organs are innervated by postganglionic axons from the celiac ganglion?

parotid salivary gland
which gland receives parasympathetic innervation from the glossopharyngeal nerve (CN IX)

superior mesenteric
postganglionic axons from the ________ ________ ganglion innervate the distal half of the duodenum, part of the pancreas, the remainder of the small intestine, the proximal part of the large intestine, the kidney, and the proximal part of the ureters

lateral horn
this area of gray matter of the spinal cord in segments T1-L2 houses the cell bodies of the sympathetic preganglionic neurons

-thoracic organs
-abdominal organs
-gonads (ovaries and testes)
-heart
-esophagus
-lungs
which structures receives parasympathetic innervation from the vagus nerve (CN X)

somatic and autonomic
the ______ nervous system and _____ nervous system are the subdivisions of the motor nervous system that transmit all motor impulses from the CNS to muscle and glands throughout the body

sympathetic
the _______ nervous system is the branch of the autonomic nervous system that is involved in the “fight or flight” reflex

parasympathetic division
which division of the autonomic nervous system is known as the “rest-and-digest” division and is responsible for conserving energy and replenishing nutrient stores?

mass activation
during an emergency or crisis situation, the sympathetic nervous system can trigger _______ _______ in which many effectors respond together

-it uses one neuron in a signaling pathway
-the effector organs are the skeletal muscle fibers
-it is under voluntary control
what statements describe the somatic motor nervous system?

rami communicantes
what connects the spinal nerves to each sympathetic trunk?

inferior and middle cervical ganglion
postganglionic axons from the sympathetic division of the autonomic nervous system innervating the thoracic viscera extends from the neuron cell bodies within the:

autonomic or visceral
stimuli associated with blood vessels or internal organs are detected by the _____ sensory structures

autonomic
the branch of the nervous system most closely associated with maintaining homeostasis is the _______ nervous system

-the effector organs are the cardiac muscle fibers, smooth muscle fibers and glands
-it is under involuntary control
-it uses two neurons in a signaling pathway
what statements describe the autonomic motor nervous system?

superior cervical ganglion
what part of the cervical portion of the sympathetic trunk distributes axons to structures within the head and neck?

-lateral gray matter of S2-S4
-brainstem
the preganglionic neurons of the parasympathetic divison originate in the:

superior mesenteric
the middle of the three prevertebral ganglia is the ______ _______ ganglion

pons
the facial nerve arises from the ______ of the brain

-urination
-defecation
two autonomic responses processed and controlled at the level of the spinal cord are:

vertebral column, aorta
prevertebral ganglia are located anterior to the _____ ______ on the anterolater surface of the ________

craniosacral
the location of preganglionic neurons in the parasymoathetic division of the autonomic nervous system allow it to be also known are the ______ division

What does dual innervation mean? Dual innervation means that a body organ receives neural innervation from both sympathetic and parasympathetic neurons on the ANS. Which division, sympathetic or parasympathetic, has longer preganglionic axons? Why? Most parasympathetic preganglionic axons are longer …

the synaptic knobs of postganglionic adrenergic neurons contain norepinephrine what are the four sympathetic pathways -spinal nerve pathway -postganglionic sympathetic nerve pathways -spanchnic nerve pathway -adrenal medulla pathway WE WILL WRITE A CUSTOM ESSAY SAMPLE ON ANY TOPIC SPECIFICALLY FOR …

Sympathetic nervous system mobilize the body’s fight-or-flight response & constantly active at a basic level to maintain homeostasis. Parasympathetic nervous system responsible for stimulation of “rest-and-digest” or “feed and breed” WE WILL WRITE A CUSTOM ESSAY SAMPLE ON ANY TOPIC …

Autonomic Nervous System v. Sensory Somatic Nervous System •peripheral nervous system divided into sensory somatic nervous system and autonomic nervous system •sensory somatic nervous system controls voluntary actions of skeletal muscle •autonomic nervous system controls involuntary actions of cardiac muscles, …

Cholinergic Drugs Affecting the Autonomic Nervous System Basic Functions of the Nervous System • Recognizes the changes in the internal environment and the external environment. • It processes and integrates environmental changes that are perceived. • It also reacts to …

Autonomic Nervous System Has 2 branches: Parasympathetic and Sympathetic. It regulates involuntary processes. Senses and receives info about digestion, respiration, heart rate. Auto control. Peripheral Nervous System Has 2 branches: Autonomic and Somatic. Autonomic is auto controlled. Somatic controls voluntary …
