Vascular smooth muscle contracts or relaxes to change both the volume of blood vessels and the local blood pressure, a mechanism that is responsible for the redistribution of the blood within the body to areas where it is needed (i.e. areas with temporarily enhanced oxygen consumption).
A germ layer is a collection of cells, formed during animal and mammalian embryogenesis.Germ layers are typically pronounced within vertebrate organisms; however, animals or mammals more complex than sponges (eumetazoans and agnotozoans) produce two or three primary tissue layers.

The dense bodies and intermediate filaments are networked through the sarcoplasm, which cause the muscle fiber to contract. Smooth muscle is grouped into two types: single-unit smooth muscle, also known as visceral smooth muscle, and multiunit smooth muscle.
In cardiology, the cardiac skeleton, also known as the fibrous skeleton of the heart, is a high-density homogeneous structure of connective tissue that forms and anchors the valves of the heart, and influences the forces exerted by and through them.
Skeletal muscle (commonly referred to as muscle) is one of the three types of vertebrate muscle tissue, the others being cardiac muscle and smooth muscle.They are part of the voluntary muscular system [1] and typically are attached by tendons to bones of a skeleton.
The heart is a muscular organ found in humans and other animals.This organ pumps blood through the blood vessels. [1] Heart and blood vessels together make the circulatory system. [2]
End plate potentials are produced almost entirely by the neurotransmitter acetylcholine in skeletal muscle. Acetylcholine is the second most important excitatory neurotransmitter in the body following glutamate.
