Heart Anatomy and Muscle Contraction

This set of vocabulary flashcards covers heart anatomy, the nervous system's control over muscle contraction, and the proteins involved in muscular density changes.

left ventricle

The most muscular chamber of the heart because it transports blood to more systems in the human body than just the lungs.

brain stem

The specific part of the nervous system responsible for the control of the heart.

nervous system

The system that must tell any muscle to contract, including both voluntary and involuntary muscles.

Contract

A process where two proteins that are far apart overlap each other and become very dense.

acting in myosin
