Use the following information to answer the next question The sympathetic nervous system secretes epinephrine at its axon terminals in the internal organs and the adrenal medulla secretes it into the bloodstream. Which of the following statements which compare the two sources of epinephrine is (are) correct? 1. Epinephrine from the sympathetic system is released faster. 2. Epinephrine from the sympathetic system is released more slowly. 3. The effects of epinephrine from the adrenal medulla last longer. 4. The effects of epinephrine from the adrenal medulla disappear more quickly. O a) 1 and 3 Ob) 3 only Oc) 1 and 4 O d) 2 and 4 O e) 1 only

Epinephrine and norepinephrine are chemicals that act as both neurotransmitters and hormones. Describe where they are released from, what organs they target and how they play a role in the sympathetic nervous system.

This gland is the link between the nervous and endocrine systems.   Select one: a. hypothalamus b. pituitary c. thyroid d. thalamus

Which of the following best describes the sympathetic nervous system? i) Associated with stressful situations ii) Norepinephrine may be involved iii) Associated with voluntary responses i only O ii only Oi and ii only i and iii only O i, ii, and iii

What are the effects of acetylcholine and norepinephrine as they relate to the functioning of the sympathetic and parasympathetic nervous system? Why has extract of deadly nightshade been an effective remedy for digestive cramps for over 2000 years?

Use the word bank below to answer the following questions (answers can be used more than once): endocrine nervous Which system is better to respond to the following: ignoring a constant low-level harmless stimulus (ex. a buzzing air conditioner) responding to a quick sudden threat maintaining a consistent signal response for months targeting one specific small tissue in a specific part of the body

If a cell were to express both alpha-1 and beta adrenergic receptors what would the expected response to epinephrine/ adrenaline be ?  a. Only cAMP would be released b. Both ca2+ and cAMP would be released c. The receptors would cancel each other and nothing would happen d. Only ca2+ would be released would be released.

You are designing neurotransmitters and hormones. 1. Which should have a higher affinity for their receptors? 2.  Which should act more rapidly?

Place the steps in the propagation of nerve impulses in the correct order. Voltage-gated sodium ion channels open in a neighboring cell membrane Sodium and potassium ion channels close Depolarization of the membrane caused by an increase in Na* permeability Hyperpolarization resulting from an increase in potassium ion permeability in response to Na ion influx

Unlike real life, pandemics in the movies often involve people turning into zombies - in which case many of us would need to run for our lives. Running for your life from zombies requires you to sense and respond to danger. Describe how your sensory, nervous, and endocrine systems would function together to help you survive a zombie apocalypse, including the specific organs, cells, tissues, molecules and/or processes involved.
