The three main breathing organs in humans are the lungs, trachea, and diaphragm. The lungs are responsible for gas exchange, allowing oxygen to enter the bloodstream and carbon dioxide to be expelled. The trachea serves as the passageway for air to travel to and from the lungs, while the diaphragm is a muscle that aids in the process of inhalation and exhalation by contracting and relaxing to change the pressure in the thoracic cavity.
The name of the muscle is sternocleidomastoid. As the name suggests, the muscle arise from the sternum and clavicle to reach the mastoid process. You have two muscles, one muscle on each side.
The muscle with the longest name is the "sternocleidomastoid." This muscle is located in the neck and plays a crucial role in rotating and flexing the head. Its name is derived from its points of origin and insertion: the sternum (sternal), clavicle (cleido), and mastoid process of the temporal bone.
Accommodation is an adjustment, especially adjustment of the eye for seeing objects at various distances. This is accomplished by the ciliary muscle, which controls the lens of the eye, allowing it to flatten or thicken as is needed for distant or near vision.
