The chordae tendinae, also referred to as heart strings, are tendons that connect the atrioventricular (tricuspid) valves to the muscular wall of the heart. These chords are made predominantly of collagen, while the remaining part is elastin. They play the vital role of maintaining the structure of the valves they connect to. Due to the high pressure generated within the heart, it is entirely possible for the atrioventricular valves to turn inside out. The chordae tendinae prevent this from happening and keep the valves functioning properly.
She should inform the students that the spinal cord is the pathway for impulses from both the brain to the body and the body to the brain. It is the central connection of nerves to the brain. It connects from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. It also manages coordinate reflexes managed by the nerves in the spinal cord.
