dormitories in the sanctuaries of Asclepius

Treatment at sanctuaries of Asclepius involved a process known as…?

temple incubation

Temple incubation

A method to induce meaningful dreams via dream divination that was used to cure illness and was used mainly at sanctuaries of the god Asclepius

Why does Asclepius have a snake (staff of Asclepius)

Various theories:

• Snakes shed their skin and seem “reborn” or healed

• snakes go under the ground and come back up, and thus seem “reborn,” healed, and/or rejuvenated

• because snakes go to and from underground, they might have been seen as communing with the dead

• Story of how Asclepius witnessed one snake resurrect another and learned from this snake

  • Venom as an antidote/medicine in some cases

What is a sanctuary?

A plot of land set apart as sacred to a particular deity. Within the sanctuary were various buildings, including a temple to the deity, storehouses, housing for the temple priests, and many other structures

Where was the main sanctuary of Asclepius?

Epidaurus

Temple incubation process

A visitor had to follow certain rituals:

• fasting (for bodily purification)

• praying to Asclepius

• bathing (also for purification)

• sacrificing to the god (e.g., a bull or sheep)

After the temple incubation process, what did a patient do in the sanctuary of Asclepius?

• spends night in abaton - sometimes many nights, depending on the severity of the illness

• sees Asclepius in their dreams

• receives advice in dreams

• upon waking up, tells the doctors of his dreams

• doctors follow the advice

• patient is miraculously cured

Systole

refers to the period of contraction of the heart when the blood is sent through the aorta and the pulmonary artery

Diastole

the period of expansion when the heart dilates and the atria and ventricles fill with blood from the venae cavae and the pulmonary vein

sphygmomanometer

Blood pressure machine

Mitral valve

lies between the left atrium and left ventricle and allows passage of blood from the atrium into the ventricle. It is also called the bicuspid valve because it has two cusps. It is meant to be a one-way valve.

Metabolism

The sum of the processes of anabolism (and catabolism). Anabolism is the constructive phase of metabolism, the process by which cells take nutrients from the blood required for repair and growth of tissue. Catabolism is the process by which complex compounds are reduced to simpler ones, often accompanied by the release of energy

History of the CF “BOL-” and it’s modern day meaning(s)

“BOL-” means a throwing. A verb diaballein had a secondary meaning which meant to make a false accusation or to slander. From this, the noun diabole (slander) was formed. The noun diabolos originally meant one who slanders an evil person. This word was used in the devil as diabolos, for devil. Some of the modern-day words that use “BOL-” have a derivative of this meaning rather than it’s meaning of a throwing. One such example of this is the word diabolic, which means devilish.

Heart

pumps blood

Artery

vessel that carries blood away from the heart to various parts of the body

Vein

Vessel through which blood passes back to the heart from various body parts

Galen

• 2nd century CE Greek working in the Roman Empire

• Worked at medical school at Alexandria

• Came up with the first main working theory of how blood circulates in the body

  • Incorrect theory, but highly influential

• Studied medicine from early age (16)

• Returned to Pergamum, became surgeon to gladiators

• on-the-job training as doctor, surgeon, nutritionist

• 162 CE on: appointed official physician to emperors Marcus Aurelius, Commodus, Septimius Severus

• Based his investigations on earlier (Greek) works of physiology and medicine

• (probably) not allowed access to human bodies

• saw inside humans via injuries and surgery

• mostly experimented on living and dead animals

• accepted doctrine of 4 humors

  • body parts and their actions resulted from different combinations of the elements, qualities, and humors

Galen’s thoughts on the cardiovascular system

• veins contain blood

• liver is source of all veins

• food becomes blood, purified in liver

• assimilated blood (in tissues) is lost via evaporation

• blood nourishes lungs

• heart intrinsically pulsates

  • contracts during phase called systole

  • dilates (expands) during phase called diastole

• respiration cools the system

• arteries contain both air and blood

• arteries and veins are different

  • arteries always pulsate

  • veins do not

• Open-ended vascular system

  • mainly blood in arteries (not air); pores in heart separate venous blood from arterial blood

What did Galen’s cardiovascular system provide an explanation for?

• digestion

• production of blood

• distribution of nourishment in body

• generation/conveyance of heat

Galen’s most significant contribution to cardiovascular discoveries

Synthesized existing knowledge from previous scholarship

• first to demonstrate (convincingly) that arteries contain blood

• narrowed down questions still needing answers (ex: movement of blood within heart)

What was Galen wrong about in regards to the cardiovascular system?

• concept of “open” circulatory system - that blood did not return to the heart or other organs (ex: liver)

• body “consumes” blood, which needs to be replenished

• liver produces blood from ingested food

• (among other things)

When were Galen’s errors corrected?

The 17th century CE by William Harvey
