Involuntary muscles are muscles that are controlled by the autonomic nervous system, so we can’t consciously control them.
All muscular tissues are designed to flux, contract, or move according to their function. Muscular tissues are categorized as visceral, cardiac, or striated. Visceral tissues, also known as smooth muscle, is associated with the internal organs found predominantly in the abdominal cavity. These organs include involuntary muscles such as the bladder, lungs,

The purpose of this essay is to describe structure and function of the tendon, present a discussion on the process of pathophysiological Tendinopathy and provide a review of known intervention used to manage or treat both acute and chronic tendinopathies. Tendons act to serve a connective tissue linking muscle to bony attachment points and in the case of the intermediate tendons that will act to link a muscle belly to another (Benjamin and Kaiser, et al). Tendons are a uniaxial and assist in force transmission thus being able to withstand external forces from multiple planes and angles (Kannus, 2008). Tendons are also responsible for storage of power and changes in the mechanical energy of the body of which in turn reduces muscular work by

As muscle contractions occur they myosin filaments bind and attach to the actin filaments Myofibril is the contractile threads found in striated muscle cells and a segment of myofibril is called a sarcomere. The role of the sarcoplasmic reticulum is storing calcium ions, as well as releasing calcium ions during muscle contractions and reabsorbing calcium ions when the muscles relax. Actin is a protein that forms the thin filament in muscle cells. Thin filaments are made up of two long chains of actin molecules that are twisted around one another.

It is an elongated muscle which allows for slow and regular contractions. The nuclei of the smooth muscle cells are centrally located and elongated, similarly to the shape of the cell. In pulmonary blood vessels and the bronchus, this muscle is used to maintain the shape and rigidity of the structure, which it does so involuntarily. The function of the pulmonary vein is the opposite to that of the pulmonary artery, in being that the pulmonary vein carries oxygenated blood back to the heart in order for the blood to be pumped around the body.
