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 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.
-
- The measurement of blood pressure without further specification usually refers to systemic arterial pressure measured at the upper arm.
- The measurement of blood pressure without further specification usually refers to the systemic arterial pressure, defined as the pressure exerted by circulating blood upon the walls of blood vessels.
- Pressure is typically measured with a blood pressure cuff (sphygmomanometer) wrapped around a person's upper arm, which measures the pressure in the brachial artery.
- A person's blood pressure is usually expressed in terms of the systolic pressure over diastolic pressure and is measured in millimeters of mercury (mmHg), for example 140/90.
- In the past, most attention was paid to diastolic pressure, but now we know that both high systolic pressure and high pulse pressure (the numerical difference between systolic and diastolic pressures) are also risk factors for disease.
-
- Chronically elevated blood pressure is called hypertension, while chronically low blood pressure is called hypotension.
- Hypertension or high blood pressure, sometimes called arterial hypertension, is a chronic medical condition in which the blood pressure in the arteries is elevated above 140/90 mmHg.
- Even moderate elevation of arterial blood pressure is associated with a shortened life expectancy.
- However, blood pressure is considered too low only if noticeable symptoms are present.

-
- Pressure ulcers, or bedsores, are lesions cause by unrelieved pressure that blocks blood flow to the skin, causing severe illness or death.
- Pressure ulcers, also known as decubitus ulcers or bedsores, are lesions caused by pressure on soft tissues overlying a bony prominence which reduces or completely obstructs the blood flow to the superficial tissues.
- The most important care for a patient with bedsores is the relief of pressure.
- For individuals with paralysis, pressure shifting on a regular basis and using a cushion featuring pressure relief components can help prevent pressure wounds.

- Dalton's law of partial pressures states that the pressure of a mixture of gases is the sum of the pressures of the individual components.
- Dalton's law states that the total pressure exerted by the mixture of inert (non-reactive) gases is equal to the sum of the partial pressures of individual gases in a volume of air.
- Mathematically, the pressure of a mixture of gases can be defined as the sum of the partial pressures of each of the gasses in air.
- Because gasses flow from areas of high pressure to areas of low pressure, atmospheric air has higher partial pressure of oxygen than alveolar air (PO2=159mmHg compared to PAO2=100 mmHg).
- Infer from Dalton's law of partial pressure the sum of partial pressures in alveoli
