Diaphragm
m. teres minor and major
A cone has a circular base.
a cylinder has to have a circular base because it is a circular prism
Strictly, if it has a circular base, it is a circular cylinder. Otherwise, it could have an oval base. If the long axis is at right angles (perpendicular) to the plane of the base, then it is a right circular cylinder.
The diaphragm is a dome-shaped muscle located at the base of the thoracic cavity, separating the chest from the abdominal cavity. It plays a crucial role in respiration, contracting to create negative pressure in the thoracic cavity, allowing air to flow into the lungs. The diaphragm is also innervated by the phrenic nerve, and it can be affected by various conditions, impacting breathing efficiency. Additionally, it has openings for structures like the aorta and esophagus, facilitating their passage between the thorax and abdomen.
A cone has a flat circular base
Half of a sphere with a circular base is called a Hemisphere.
Hiccups are caused by spasms of the diaphragm, the muscle located at the base of the chest that separates the thoracic cavity from the abdominal cavity. When the diaphragm contracts involuntarily, it results in a sudden intake of air that is abruptly stopped by the closure of the vocal cords, producing the characteristic "hic" sound. This reflex can be triggered by various factors, including overeating, drinking carbonated beverages, or sudden temperature changes.
In a right circular cone a line from the vertex to the center of the circular base is perpendicular to the base. In an oblique circular cone that same line will not be perpendicular.
A right circular cone is perfectly balanced on its circular base. Imagine a cone that has a circular base, but leans to one side - this is a non right circular cone.
cylinder is the name for a circular prism
A shape with a circular base and a vertex that isn't in the same plane as the base is called a cone.
