Explain Vasodilation
In efforts to release heat from the body, the arterioles dilate allowing heat to be released from the skin.
Law of Inertia: An object in motion tends to stay in motion and an object at rest tends to stay at rest unless acted upon by an external force.
Law of Acceleration: A force applied to an object causes an acceleration of that object of a magnitude proportional to the force and in the direction of the force, but inversely proportional to the mass.
Law of Action-Reaction:For every action there is an equal and opposite reaction.
Infancy: birth - 2 or 3
Childhood: 4-10
Puberty: 11-18
Adulthood: 18+
List the 7 Steps of an Action Potential arriving at the Neuromuscular Junction.
1. Action Potential travels down the axon.
2. Electrical grated calcium channels open.
3.Calcium triggers the vesicles to release ACH into the synaptic cleft.
4. ACH diffuses across the cleft and binds to receptors.
5.ACH bind opens sodium channels and Na rushes into the muscle.
6.If the muscle reaches the threshold of (-55mv) a muscle contraction occurs.
7. ACH is broken down by acetylcholine esterase.
