Question: Is the pre-synaptic or the post-synaptic neuron damaged? Explain your rationale in detail (in other words, detail how you came to your conclusion). You're going to have to really think on this one. It's not something you can look up in the text. You will need to use what you have learned about the autonomic nervous system and some critical thinking to arrive at the answer.
Horner's Syndrome riddle: Ach is the neurotransmitter at all ANS preganglionic fibers, including SNS. The pt has decreased sweating and pupil constriction, indicating blockage of SNS transmission. When the MD gave ACh it induced sweating, but not pupil dilation. This is because the sweat glands are an exception in normal SNS transmission, as the postganglionic fibers utilize ACh as their neurotransmitters. Other SNS pathways utilize NE as their neurotransmitter. So ACh acted directly on the sweat gland to produce sweating, but could not stimulate the typical postsynaptic neurons to release NE. When the MD gave NE he saw pupil dilation, but not sweating, indicating the NE worked directly at the iris to produce pupil dilation. This indicaates the problem was with the postsganglionic neuron. If the preganglionic neuron were the problem injecting ACh would have solved both problems.
because while plants are exhaling oxygen humans are inhaling it but when humans exhale carbon plants would inhale it.
This question is incomplete. Here´s the complete question.
A 70-year-old client with a diagnosis of left-sided stroke is admitted to the facility. To prevent the development of disuse osteoporosis, which objective is most appropriate?
a) Promoting range-of-motion (ROM) exercises
b) Promoting weight-bearing exercises
c) Maintaining protein levels
d) Maintaining vitamin levels
Answer: b) Promoting weight-bearing exercises
Explanation:
The bone is a living tissue that becomes stronger with exercise. Weightlessness and immobility can lead to bone loss.
Weight-bearing exercises are those that force us to work with gravity, like walking, hiking, jogging, climbing stairs, playing tennis, and dancing. They can help prevent disuse osteoporosis.
On the other hand, swimming and bicycling would be examples of non-weight-bearing exercises.
yes they are quit different in some things
