The activities of the digestive system are regulated by:
a) Hormones
b) Parasympathetic and Sympathetic neuron
c) The content of the digestive tract
d) A and B only
Answer is option D
Digestive system activities are regulated by both hormones, sympathetic and parasympathetic activities( by sight, taste, imagination, thoughts of food etc) . This helps in secretion of hormones, increase the Digestive tract mortality and contraction production of Digestive enzymes like cck, Hcl... Etc

Digestive System Roles of the digestive tract lining Sympathetic vs. parasympathetic stimulation digestive tract Myenteric plexus Pre/Enzyme- where secreted from and function (gastrin, somatostatin, pepsinogen, mucus, lipase, secretin, insulin, CCK, GIP)… what/where does it stimulate or inhibit What is deglutition? Gastric regulation- cephalic vs. gastric vs. intestinal Where does blood go after leaving the intestine? What does the colon do? Process of defecation
15-23 15) The sympathetic and parasympathetic nervous systems differ A) one has a two-neuron chain from the CNS to the effector organs, while the other has a singe 15) efferent neuron. B) in the body location of their ganglia C) in that the pre-ganglionar neuron of one systen is inside the CNS, while that of the other system is outside the CNS D) one has only myelinated axons, while the other only has unmyelinated axons 16) Collections of nerve cell...
1.Compare and contrast the actions of the parasympathetic and sympathetic divisions of the autonomic nervous system. Explain how the sympathetic and parasympathetic nervous systems regulate the heart, digestive tract, respiratory tract, reproductive tracts, arteries, salivary and sweat glands, and portions of the eye. 2. Describe the nurse’s role in the pharmacologic management of patients receiving drugs affecting the parasympathetic nervous system. Identify which drugs would be used for paralytic ileus, GERD, and irritable bowel syndrome and explain the mechanism of...

What is the entire point of the sympathetic response? 4. Which division of the ANS raises blood sugar and oxygen? 5. Which division of the ANS promote mucus secretion and iris constriction? 6. How can norepinephrine dilate some blood vessels and constrict others? 1. How can imagine a stress state? 2. What does the parasympathetic nervous system...
5.1. What are the two main divisions of the vertebrate nervous system? A) parasympathetic and sympathetic B) autonomic and sympathetic nervous system C) Brain and Spinal Cord D) Central Nervous System and Peripheral Nervous System 5.2. What are the three major structures that make up the diencephalon? A) The medulla, the pituitary gland, and the hindbrain B) The thalamus, hypothalamus and pituitary gland c) The pons, the hypothalamus, and the optic tract D) The motor cortex, the occipital lobe, and...
1. Explain how each of these systems (sympathetic / parasympathetic) affect each of the following: A. heart rate B. blood pressure C. digestive muscles D. digestive glands E. adrenal medulla F. blood vessels to skeletal muscles G. blood vessels to respiratory system H. blood vessels to digestive organs I. blood vessels to skin.
Sympathetic Effect Parasympathetic Effect Organ Function Secretion of saliva from salivary glands Activity (motility) of digestive tract Secretion of enzymes from pancreas Contraction of gall bladder Urine output from kidneys Contraction of urinary bladder Release of hormones from adrenal medulla Secretion of sweat Contraction of arrector pili muscles Breakdown of fats in adipose tissue Erection of penis/clitoris Ejaculation/contraction of penis/vagina To learn more about some of the characteristic differences between the sympathetic (S) and parasympathetic (PS) divisions of the ANS,...
Which of the following is NOT correctly matched regarding the sympathetic system (SYM) and parasympathetic system (PARA)? a. SYM: forms sympathetic trunk b. PARA: has terminal ganglia on or near a visceral organ c. SYM: both pre- and postganglionic neurons have adrenergic receptors d. PARA: both pre- and postganglionic neurons have cholinergic receptors
5. Draw a diagram of the preganglionic neuron, postganglionic neuron, and effector for both Sympathetic Nervous System and Parasympathetic Nervous System. indicate which neurotransmitter is released by each neuron and label the receptors at all locations for the neurotransmitter. 6. Which cells have a resting membrane potential? Which cells can have an action potential? 7. Circle which of the following choices pertain to a Graded Potential. (1) Localized or Widespread (2) Gradations or All-or-None (3) Threshold or Not (4) Short...
