Q

Inferior

A

Refers to a structure that is situated near the soles of the feet. Caudal pertains to the tail and is a useful directional term when referring to the tail or trunk region (used by embryologist)

18
Q

Greeks 4 body humors 1200-200BC

A

Blood/sangius - liver
Phlegm/phelgma- lungs
Yellow bile/chole- gallbladder
Black bike/melanchole- spleen

19
Q

Hippocrates

A

Father of medicine
460-377BC

20
Q

Aristotle

A

Wrote first known account of embryology (with chicks)
384-332 BC
Proclaimed the heart to be the seat of intelligence
Thought that the function of the brain was to maintain body temperature

21
Q

Herophilus

A

304 BC
Gave rise to the term anatomy
Court physician
Began dissection of cadavers

Described anatomical structures
1. Brain and it’s meninges
2. Vascular network and venous sinuses and their confluence (Torcular herophili)
3. Nerves which he distinguished from tendons
4. Differentiated arteries from veins
5. Discovered prostrate and duodenum

22
Q

Claudius Galen

A

Roman physician
120 - 200AD
Team doctor for gladiators
Proved that arteries carry blood not air
Believed blood originated in the liver

23
Q

Omi animal ex ovo meaning

A

All life originates from an egg

24
Q

What is flexion?

A

Flexion indicates bending or decreasing the angle between the bones or parts of the body.

25
Q

What is dorsiflexion?

A

Describes flexion at the ankle joint, as occurs when walking uphill or lifting the toes off the ground.

26
Q

What is plantarflexion?

A

Turns the foot or toes toward the plantar surface (e.g., when standing on your toes).

27
Q

What is extension?

A

Extension indicates straightening or increasing the angle between the bones or parts of the body.

28
Q

What is hyperextension?

A

occurs when a part of the body is extended beyond the anatomical position so that the joint angle is greater than 180°.

29
Q

What is abduction?

A

Means moving away from the median plane in the coronal plane (e.g., when moving an upper limb away from the side of the body).

30
Q

What is adduction?

A

Means moving toward the median plane in a coronal plane (e.g., when moving an upper limb toward the side of the body).

31
Q

What is rotation?

A

Involves turning or revolving a part of the body around its longitudinal axis, such as turning one’s head to the side.

32
Q

What is inversion?

A

Inversion moves the sole of the foot toward the median plane (facing the sole medially). When the foot is fully inverted it is also plantarflexed.

33
Q

What is eversion?

A

Eversion moves the sole of the foot away from the median plane (turning the sole laterally). When the foot is fully everted it is also dorsiflexed.

34
Q

What is opposition?

A

Is the movement by which the pad of the 1st digit (thumb) is brought to another digit pad.

35
Q

What is reposition?

A

describes the movement of the 1st digit away from the position of opposition back to its anatomical position.

36
Q

What is protusion?

A

Is a movement anteriorly (forward) as occurs in protruding the mandible (sticking the chin out).

37
Q

What is retrusion?

A

is a movement posteriorly (backward) as occurs in retruding the mandible (tucking the chin in).

38
Q

What is pronation?

A

Is the movement of the forearm and hand that rotates the radius medially so that the palm of the hand faces posteriorly and its dorsum faces anteriorly

39
Q

What is supination?

A

Is the movement of the forearm and hand that rotates the radius laterally so that the dorsum of the hand faces posteriorly and the palm faces anteriorly (i.e., moving them into the anatomical position).
