Cardiac muscle --> muscle
(Science: anatomy) tissue specialised for contraction. See twitch muscle, catch muscle: cardiac muscle (heart muscle) is a striated but involuntary Muscle responsible for the pumping activity of the vertebrate heart. The individual muscle cells are joined through a junctional complex known as the intercalated disc and are not fused together into multinucleate structures as they are in skeletal muscle. Skeletal muscle is a rather non-specific term usually applied to the striated muscle of vertebrates that is under voluntary control. The muscle fibres are syncytial and contain myofibrils, tandem arrays of sarcomeres. Smooth muscle is muscle tissue in vertebrates made up from long tapering cells that may be anything from 20-500m long. Smooth muscle is generally involuntary and differs from striated muscle in the much higher actin/myosin ratio, the absence of conspicuous sarcomeres and the ability to contract to a much smaller fraction of its resting length. Smooth muscle cells are found particularly in blood vessel walls, surrounding the intestine (especially the gizzard in birds) and in the uterus. The contractile system and its control resemble those of motile tissue cells (for example fibroblasts, leucocytes) and antibodies 4ea
against smooth muscle myosin will cross react with myosin from tissue cells, whereas antibodies against skeletal muscle myosin will not.

... stimulus it launches an action potential, and this will cause the muscle to contract. The AP is an absolute value (it's either ON or OFF) so ... a greater number of contractions would pump more, but this would be cardiac output rather than SV. 2. See above 3. Okay well the heartbeat is ...
