Examples of Pressure epiphysis in the following topics:
-
- The epiphysis is the rounded end of a long bone, at its joint with adjacent bone(s).
- The region of the long bone that forms the joint is called pressure epiphysis.
- For example, the head of the femur (which is a part of the hip joint complex) is a pressure epiphyses.
- These epiphyses assist in transmitting the weight of the human body and are the regions of the bone that are under pressure during movement or locomotione.
- Another example of pressure epiphysis is the head of humorus, part of the shoulder complex.
-
- Their sites of entry and angulation are almost constant and characteristically directed away from the growing epiphysis.
- These approach the epiphysis dividing into smaller rami.
- Near the epiphysis, they anastomose with the metaphyseal and epiphyseal arteries.
- The blood supply of the immature bones is similar, but the epiphysis is a discrete vascular zone separated from the metaphysis by the growth plate.
-
- The pineal gland (also called the pineal body, epiphysis
cerebri, epiphysis, conarium, or the "third eye”) is the only unpaired midline brain structure.
-
- The epiphysis of a bone, such as the neck of the femur, is subject to stress from many directions.
- In this case, the function of the toothpick is to transmit the downward pressure of the picture to the wall.
-
- Pressure is often measured as gauge pressure, which is defined as the absolute pressure minus the atmospheric pressure.
- Gauge pressure is a relative pressure measurement which measures pressure relative to atmospheric pressure and is defined as the absolute pressure minus the atmospheric pressure.
- Most pressure measuring equipment give the pressure of a system in terms of gauge pressure as opposed to absolute pressure.
- For example, tire pressure and blood pressure are gauge pressures by convention, while atmospheric pressures, deep vacuum pressures, and altimeter pressures must be absolute.
- Explain the relationship among absolute pressure, gauge pressure, and atmospheric pressure
-
- The metaphysis is the wide portion of a long bone between the epiphysis and the narrow diaphysis.
- These chondrocytes do not participate in bone growth; instead, they secure the epiphyseal plate to the osseous tissue of the epiphysis.
- This illustration shows the zones bordering the epiphyseal plate of the epiphysis.
- The topmost layer of the epiphysis is the reserve zone.
-
- The epiphysis is the rounded end of a long bone located at its joint with adjacent bone(s).
- Between the epiphysis and diaphysis (the long midsection of the long bone) lies the metaphysis, including the epiphyseal plate (growth plate).
-
- Measurement of blood pressure includes systolic pressure during cardiac contraction and diastolic pressure during cardiac relaxation.
- Blood pressure is the pressure blood exerts on the arterial walls.
- These pressures, called segmental blood pressures, are used to evaluate blockage or arterial occlusion in a limb (for example, the ankle brachial pressure index).The difference between the systolic and diastolic pressure is called the pulse pressure.
- A blood pressure cuff and associated monitor used for determining systolic and diastolic pressures within an artery.
- Explain how blood pressure is measured and the ranges of blood pressure readings
-
- Blood pressure is a vital sign reflecting the pressure exerted on blood vessels when blood is forced out of the heart during contraction.
- Blood pressure is the pressure that blood exerts on the wall of the blood vessels.
- Systolic pressure is thus the pressure that your heart emits when blood is forced out of the heart and diastolic pressure is the pressure exerted when the heart is relaxed.
- During each heartbeat, blood pressure varies between a maximum (systolic) and a minimum (diastolic) pressure.
- A normal blood pressure should be around 120/80, with the systolic pressure expressed first.
-
- Gas pressures in the atmosphere and body determine gas exchange: both O2 and CO2 will flow from areas of high to low pressure.
- Each gas component of that mixture exerts a pressure.
- The pressure for an individual gas in the mixture is the partial pressure of that gas.
- The pressure of the water vapor in the lung does not change the pressure of the air, but it must be included in the partial pressure equation.
- For this calculation, the water pressure (47 mm Hg) is subtracted from the atmospheric pressure: 760 mm Hg 47 mm Hg = 713 mm Hg, and the partial pressure of oxygen is: (760 mm Hg 47 mm Hg) 0.21 = 150 mm Hg.
