Elevation and depression are movements above and below the horizontal. The words derive from the Latin terms with similar meanings. [c] Elevation is movement in a superior direction. [19] For example, shrugging is an example of elevation of the scapula. [20] Depression is movement in an inferior direction, the opposite of elevation. [21]
Agonist muscles are also called prime movers since they produce most of the force, and control of an action. [6] Agonists cause a movement to occur through their own activation. [ 7 ] For example, the triceps brachii contracts, producing a shortening (concentric) contraction , during the up phase of a push-up ( elbow extension ).
Pectinate muscles make up the part of the wall in front of this, the right atrial appendage. [citation needed] In the left atrium, the pectinate muscles are confined to the inner surface of its atrial appendage. [1] They tend to be fewer and smaller than in the right atrium.
The papillary muscles are muscles located in the ventricles of the heart. They attach to the cusps of the atrioventricular valves (also known as the mitral and tricuspid valves) via the chordae tendineae and contract to prevent inversion or prolapse of these valves on systole (or ventricular contraction).
Gross anatomy has become a key part of visual arts. Basic concepts of how muscles and bones function and deform with movement is key to drawing, painting or animating a human figure. Many books such as "Human Anatomy for Artists: The Elements of Form", are written as a guide to drawing the human body anatomically correctly. [4]
From ancient history to the modern day, the clitoris has been discredited, dismissed and deleted -- and women's pleasure has often been left out of the conversation entirely. Now, an underground art movement led by artist Sophia Wallace is emerging across the globe to challenge the lies, question the myths and rewrite the rules around sex and the female body.
The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...
