Muscles produce movement by: a. acting on the bones of the skeleton b. pumping blood c. propelling substances throughout hollow organ systems 2. Muscles aid in maintaining posture by adjusting the position of the body with respect to gravity. 3. Muscles stabilize joints by exerting tension around the joint. 4.

Overview Ocular rosacea is a condition in which inflammation causes burning‚ itching‚ and redness in the eyes. As implied by the name‚ it is often seen in patients who already have rosacea on the face‚ but it may also be the first indication that the condition will develop later in life. Ocular rosacea usually affects middle-aged adults‚ many of whom tend to flush or blush more easily than most people. It can ultimately lead to various problems with vision and‚ in the worst cases‚ vision loss.

potential which increases the concentration of calcium ions into the cell. Calcium ions play a key role in activating what is known as the contractile machinery – the actin and myosin filaments. The cardiac action potential‚ unlike other forms of muscular contraction‚ will last roughly as long contraction. This is shown below‚ depolarisation is followed by an unusual plateau‚ and the cardiac action potential can be split into five main phases. Cardiomyocytes are also electrically coupled – so they
