Q

Theory vs Law

A

Law - a scientific law is a theory, or explanation of a scientific principle, with an extraordinary high degree of confidence of scientists based on experimentation

Theory - an explanation of a scientific principle that has been tested experimentally and found to be true; compare to hypothesis and law

10
Q

What is a group of several different kinds of tissues arranged in ways that allow them to act as a unit to perform a special function? Is also larger and more complex than tissues.

A

Organs

Unlike microscopic molecules and cells, some tissues and most organs are gross (large) structures that can be seen easily without a microscope.

Q

Posterior (dorsal)

A

– back, at the back of

18
Q

Medial

A

– towards the midline of the body

19
Q

Lateral

A

– towards the side, away from the midline

20
Q

Proximal

A

–nearest the trunk of the body or nearest the point of origin of a body part

21
Q

Distal

A

– away from or farthest from the trunk or point of origin of a body part

22
Q

Superficial

A

– nearer the surface of the body

23
Q

Deep

A

– farther away from the body surface

24
Q

Sagittal plane

A

– a lengthwise plane running from front and back dividing the body into right and left portions

25
Q

Midsagittal plane

A
  • divides body into equal right and left halves
26
Q

Frontal or Coronal plane

A

– a lengthwise plane running from side to side dividing the body into anterior and posterior portions

27
Q

Transverse plane

A

– a horizontal or crosswise plane dividing the body into upper and lower portions

28
Q

Ventral Cavities

A

1.1 Thoracic cavity or Chest cavity
1.1.1 Mediastinum - contains the heart, trachea, esophagus, aorta, vena cavae, pulmonary artery, pulmonary veins, thymus
1.1.2. Pleural cavities - contain the lungs

29
Q

Abdominal Cavity

A

-contains the stomach, intestines,
liver, gall bladder, pancreas, spleen, kidneys, adrenal glands

30
Q

diaphragm

A

The diaphragm anatomically separates the thoracic cavity
from the abdominal cavity below.

31
Q

Pelvic cavity

A
  • contains the urinary bladder,
    uterus, fallopian tubes, ovaries, rectum, prostate gland

There is no anatomical structure that separates the abdominal cavity from the pelvic cavity, hence the term
abdominopelvic cavity to refer to the two cavities taken as a whole.

32
Q

Dorsal Cavities

A

2.1 Cranial cavity -
contains the brain

2.2 Spinal cavity -
contains the spinal
cord

33

Right Upper or
Right Superior Quadrant holds what organs?

A

Liver (right lobe)
Gallbladder
Pylorus (of stomach)
Duodenum
Pancreas (head)
Right kidney and adrenal gland
Colon: upper ascending colon,
hepatic flexure and right half of
transverse colon

34
Q

Left Upper or Left Superior
Quadrant holds what organs

A

Liver (left lobe)
Spleen
Stomach
Part of jejunum
Proximal ileum
Pancreas (body and tail)
Left kidney and adrenal gland
Colon: left half of transverse
colon, splenic flexure and
superior part of descending
colon

35
Q

Right Lower or Right
Inferior Quadrant holds what organs?

A

Majority of ileum
Cecum with vermiform
appendix
Lower ascending colon
Right ureter
Right ovary
Right fallopian tube

36
Q

Q

The hierarchy of structural organization

A

. Chemical Level - Atoms form molecules
. Cellular Level - Cells and their functional subunits
. Tissue Level - A group of cells performing a common function

. Organ System Level - Organs working together for a common purpose
. Organismal Level - The result of all simpler levels working in unison
