seratonin

norepinephrine

dopamine

glutamate

acetylcholine

K+ channels close

Na+ channels close

A __________ is when two or more hormones work together to perform a common function.

synergistic interaction

permissive interaction

agonistic action

antagonistic action

Answer 1

1.The answer is option A

somatic efferent neurons are motor nuerons.They conduct the impulses from the grey matter of the spinal cord to the skeletal muscles.

2.The last thing to happen in the sequence of the generation of an individual action potential is the closing of the pottasium ion channels.This occurs after the hyperpilarization.

3.The answer is norepinephrine.

The norepinephrine activates the adrenergic response in the autonomic nervous system.The Norepinephrine is released by the postsynaptic neurons.

4.The answer is option A

synergestic action is the process in which two or more hormones work together to produce a particular action.Eg:epinephrine and norepinephrine,prolactin and oxyt
