Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which 2 body systems interact and INITIATE (start or signal to move) movement?
A
muscular and nervous system
B
skeletal and muscular system
C
respiratory and nervous system
D
circulatory and nervous system
Explanation: 

Detailed explanation-1: -Movements happen when: Your nervous system (brain and nerves) sends a message to activate your skeletal (voluntary) muscles. Your muscle fibers contract (tense up) in response to the message.

Detailed explanation-2: -The Nervous System and Muscular System In a similar fashion, the receptors in the muscular system communicate with the nervous system regarding muscle movement and position, and the brain takes over the control of the skeletal muscles by returning signals.

Detailed explanation-3: -Communication among organ systems is controlled mainly by the autonomic nervous system and the endocrine system. The autonomic nervous system is the part of the nervous system that controls involuntary functions.

Detailed explanation-4: -The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction.
