All three muscle tissues have some properties in common. Muscular system anatomy muscle types.
Types Of Muscle Tissues Anatomy And Physiology
The striation is due to the regular alternation of the contractile proteins actin and myosin along with the structural proteins that couple the contractile proteins to connective tissues.
Anatomy of muscle tissue. Smooth muscle tissue contraction is responsible for involuntary movements in the internal organs. Muscle tissue is attached to the bones through tendons which are highly elastic portions of connective tissue. Smooth muscle lines the walls of blood vessels and certain organs such as the digestive and urogenital tracts where it serves to advance the movement of substances.
Nervous tissue allows the body to receive signals and transmit information as electric impulses from one region of the body to another. Three kinds of muscle tissue exist. Ap principles of anatomy and physiology 13th edition muscle functions.
Skeletal muscle tissue is arranged in bundles surrounded by connective tissue. Muscle cells or myocytes contain myofibrils comprised of actin and myosin myofilaments which slide past each other producing tension that changes the shape of the myocyte. Anatomy and physiology chapter 10 muscle tissue.
There are three types of muscle tissue. Visceral smooth muscle visceral muscle is found in various parts of the body including blood vessels the bladder digestive tract as well as in many other hollow organs. Skeletal muscle cardiac muscle and smooth muscle.
Like cardiac muscle most visceral muscle is regulated by the autonomic nervous system and is under involuntary control. Muscle tissue which responds to stimulation and contracts to provide movement is divided into three major types. The weakest of all muscle tissues visceral muscle makes organs contract to move substances through the organ.
Movement stablizing storing and moving substances throughout body heat generation. They all exhibit a quality called excitability as their plasma membranes can change their electrical states from polarized to depolarized and send an electrical wave called an action potential along the entire length of the membrane. Skeletal voluntary muscles smooth muscles and the cardiac muscle in the heart.
Many muscles may seem to control a single appendage but in reality each one only controls one small aspect of movement. Each cell is spindle shaped with a single nucleus and no visible striations figure 441 muscle tissue. Anatomy and physiology chapter 10 muscle tissue book.
Visceral cardiac and skeletal. Smooth muscle is called involuntary muscle because it is not under direct conscious control. It forms the contractile component of the digestive urinary and reproductive systems as well as the airways and blood vessels.
Visceral muscle is found inside of organs like the stomach intestines and blood vessels. While the nervous system can influence the excitability of cardiac and smooth muscle to some degree skeletal muscle completely depends on signaling from the nervous system to work properly. Under the light microscope muscle cells appear striated with many nuclei squeezed along the membranes.
Muscle tissue muscle is a soft tissue that is highly specialized for the production of tension which results in the generation of force.
