A cardioid microphone exhibits an acoustic pickup pattern that, when graphed in two dimensions, resembles a cardioid (any 2d plane containing the 3d straight line of the microphone body). In three dimensions, the cardioid is shaped like an apple centred around the microphone which is the "stalk" of the apple.
the fibular region encompassing the outside of the lower leg, the tarsal region encompassing the ankle, the pedal region encompassing the foot; the digital/phalangeal region encompassing the toes. The great toe is referred to as the hallux. The regions of the upper limbs, from superior to inferior, are the axillary region encompassing the armpit,
The seahorse "body" is composed by 25 "spokes" consisting of two groups of 12 "spokes" each and one "spoke" connecting to the main cardioid. These two groups can be attributed by some metamorphosis to the two "fingers" of the "upper hand" of the Mandelbrot set; therefore, the number of "spokes" increases from one "seahorse" to the next by 2 ...
The cardioid is the special case in which the point generating the roulette lies on the rolling circle; the resulting curve has a cusp. Depending on the position of the point generating the curve, it may have inner and outer loops (giving the family its name), it may be heart -shaped, or it may be oval.
The mid-clavicular line, a line running vertically down the surface of the body passing through the midpoint of the clavicle. In addition, reference may be made to structures at specific levels of the spine (e.g. the 4th cervical vertebra , abbreviated "C4"), or the rib cage (e.g., the 5th intercostal space ).
The right coronary artery supplies oxygenated blood to the right atrium, the right ventricle, and the posterior third and inferior end of the interventricular septum. [2] [5] It may also supply 25% to 35% of the left ventricle (LV). [10] There is significant overlap of supply of the coronary arteries. [2]
The stretch on the individual cell, caused by ventricular filling, determines the sarcomere length of the fibres. Therefore the force (pressure) generated by the cardiac muscle fibres is related to the end-diastolic volume of the left and right ventricles as determined by complexities of the force-sarcomere length relationship.
The heart is a four-chambered organ consisting of right and left halves, called the right heart and the left heart. The upper two chambers, the left and right atria , are entry points into the heart for blood-flow returning from the circulatory system , while the two lower chambers, the left and right ventricles , perform the contractions that ...
