Question

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, use the textbook (Table 14.1 and Figures 14.2, 14.3, 14.4, 14.6 & 14.7) as a reference to complete the table below. For each feature/characteristic listed in column 1, indicate with a check mark (in either column 2 or 3) which division has that feature/characteristic. Feature/Characteristic More active when individual is at rest or digesting a meal More active when individual is active or under stress Simultaneous, widespread effects on various target organs More specific control of effects at different target organs Motor pathways found in cranial and sacral nerves Motor pathways found in spinal nerves T, through L Adrenergic fibers secrete norepinephrine as neurotransmitter at target organs Cholinergic fibers secrete acetylcholine as neurotransmitter at target organs Cercise 5 - Somatic Reflexes

Answer 1

Secretion of enzyme from pancreas - sympathetic - negative, parasympathetic - positive

Release of hormone from adrenal medulla, sympathetic - negative, parparasympathetic- positive

Secretion of sweat, sympathetic. - positive  ,   Parasympathetic - negative

Contraction of errector pilli muscle, sympathetic positive, parasympathetic negative

Break down of fat in adipose tissue, sympathetic. Positive, Parasympathetic -negative

Erection of genital organ , sympathetic - negative, parasympathetic - positive

Ejaculation / contraction of male genital organ  / clitoris, sympathetic - negative, parasympathetic - positive

More active when individual is at rest. Sympathetic - negative, parasympathetic - positive

More active when individual is active or stress, sympathetic - positive, parasympathetic - negative

Widespread effect on various target organs , sympathetic - positive, parasympathetic - negative

More specific effect of control at different s target organ, sympathetic positive, parasympathetic negative

Motor pathway found in cranial or sacral nerve, sympathetic - negative, parasympathetic - positive

Motor pathway found in T1 nerve through L3 , sympathetic negative, parasympathetic - positive

Adrenergic fiber secrete norepinephrine as neurotransmitter at target organ , sympathetic - positive parasympathetic - negative

Cholinegic fiber secrete acetylcholine as neurotransmitter at target organ, sympathetic - negative parasympathetic - positive
