25
closing of a joint is what action?
flexion
26
opening of a joint is what action?
extension
27
an anatomical position are the hands in pronation or supination
supination
28
When in anatomical position, why are the hands in supination?
the bones of the forearms (radius/ulna) are uncrossed in the supination position
29
define elevation and depression??
elevation is moving upward | depression is moving downward
30
define retraction and protraction...
protraction- movement in anterior direction | retraction- movement in posterior direction
31
This body division includes the head, neck and trunk
axial division
32
This vertical plane that divides the body into right and left planes
sagittal
33
A transverse plane divides the body into two parts
superior and inferior
34
These cuts/sections are made diagonally between the horizontal and vertical planes
oblique
35
This body cavity protects the nervous system...
dorsal cavity
36
This body cavity encloses the brain...
cranial cavity
37
This cavity encloses the spinal cord...
spinal cavity
38
The frontal plane is also known as the......
coronal
39
The ventral body cavity is divided into these two cavities...
thoratic and adbominopelvic
40
This cavity encloses the heart
pericardial cavity
41
The outer surface of the organs and body cavities are covered by this double layered membrane called
serosa
42
What is pleurisy?
inflamation of the pleurae
43
the abdominopelvic region is divided into what four quadrants?
right upper, left upper | right lower, left lower
44
This region surrounds the naval
umbilical
45
This region houses the pelvis
lliac
46
This cavity houses the teeth and tongue
oral cavity
47
this cavity houses the eyes
orbital
48
Joints are lined with what?
synovial fluid
49
Name the Synovial cavity's middle ear bones
middle ear: malleus, incus, stapes
50
Explain why active metabolizing cells need to be relatively small
Active metabolizing cells need to be small because as the cell expands, the surface area decreases. The metabolic cells are able to process waste and diffusions at a faster speed.
51
Explain 3 differences between prokaroyotic and eukaryotic cells.
1. prokaryotic cells are typically smaller than eukayotic cells (prokaryotic means "before the nucleus") 2. Prokaryotic cells do not have a nuclear membrane 3. prokaryotic cells do not contain membrane-bound organelles
52
Define Nucleus
Contains DNA and is the control center of the cell
53
what are ribosomes?
tiny manufacturing plants that assemble proteins
54
what is Smooth ER?
synthesis of lipids
55
what is rough ER?
modifies and transports proteins
56
what is RNA, or ribonucleaic acid synthesize?
proteins
57
what is endospore?
extremely durable and dormant cell that is made from bacteria which can lead to botulism;
58
what is golgi complex?
receives lipids and proteins synthesized by the endoplasmic reticulum , altering their structures and shipping them to other parts of the cell
59
What is Lysosome?
digestive enzymes which break down biomarcomolescules
60
What is mitochondria?
converts chemical energy found in ATP (which provides energy for the cell)
61
What is plasma membrane?
surrounds cells and contains "pumps" and gates" that regulate the passage of materials in & out of cell.
62
what are microtubules ?
hollow and attached to MTOC
63
what are microfilaments?
are solid and create movement
64
extracellular matrix
has collagen fibers which are found in humans and animals
65
Describe aerobic respiration and purpose of ATP
Eukayrokic cells must have mitochondria in order to converts chemical energy found in food (glucose) into ATP. ATP provides energy to the cell.During cellular respiration, oxygen helps break down the food. Carbon dioxide, water and ATP are made here.
66
What is tay-sachs disease?
Lacks digestive enzyme, lysosomes. Toxic lipid in brain cells cannot be broken down.. Lipids build up which can cause disability and death
67
What are 3 main differences between eukaryotic and prokaryotic cells?
size, organelles and membranes
68
Diffusion is a form of what kind of transport? Passive or Active? Why?
Passive because more energy is released
