Re: Student Questions

Title: Student Question

Good morning all:   I have a couple of student-initiated questions with which I need some help. First, a student asked why most of us swing our arms as we walk.   Second, a student asked if melatonin produced by the pineal gland is considered a hormone or a neurotransmitter and another asked about norepinephrine and epinephrine, produced by the adrenal glands; again are these hormones or neurotransmitters?   And I have a question: Are norepinephrine and epinephrine also called adrenaline and noradrenaline? Is there a distinction between them?   Thanks for the info in advance. It's appreciated!!   Jean Edwards [EMAIL PROTECTED] --- You are currently subscribed to tips as: [EMAIL PROTECTED] To unsubscribe send a blank email to [EMAIL PROTECTED]
