Echocardiogram is the cardiac test that helps in evaluating cardiac chamber size and ventricular function. It uses ultrasound waves to create images of the heart's structure and function. It is a non-invasive and commonly used test in cardiology.
Your cardiac muscles is your heart. Make a fist with one of your hands. This is the closest and most accurate shape and size of YOUR heart.
The thoracic spine, where movement of the spinal column is most limited.
The placenta is attached to the backwall of the uterus - the side closest to the mother's spine.
The muscle of the Erector Spinae group that is located closest to the spine is the spinalis muscle. It runs alongside the vertebral column and is the most medial component of the Erector Spinae group, which also includes the longissimus and iliocostalis muscles. The spinalis primarily functions to extend and laterally flex the spine.
Yes, you can have a cervical spine (first part of the spine, closest to the brain) and the cervix in women (junction between vagina and the uterus.
Cardiac muscles are involuntary. Cardiac muscles are what makes the heart pump. Cardiac muscles are only in your heart. If those muscles were voluntary, organisms would most likely die. Skeletal muscles are voluntary. You can move any part of your body freely with these muscles, unless you are paralized in which your skeletal muscles are damaged, the nerve cells from those muscles to the spine are damaged, or the spine itself is damaged. Skeletal muscles are found in all of the body. In an average person, skeletal muscles make up 40% of body weight. So:: Cardiac muscles are INVOLUNTATY Skeletal muscles are VOLUNTARY
do you mean aneurysmectomy? it's a surgical precedure to remove an aneurysm. an aneurysm is a circumscribed dilation of an artery or a cardiac chamber, in direct communication with the lumen, usually resulting from the acquired or congential weakness or the wall of the artery or the chamber.
Sudden cardiac death is usually caused by ventricular fibrillation (the lower chamber of the heart quivers instead of pumping in an organized rhythm).
