The Endocrine System partners with the Nervous System in regulating the human body and controlling the responses to physiological challenges. What are the two differences in their responses.
Nervous System= immediate response, short duration of effects.
Endocrine System= slower response, longer duration of effects.
Opening of the joint angle around the sagittal axis at the joint, such as during jumping jacks, is known as what?
