Cards

Term
Anions
Definition
An ion bearing a positive charge ( i.e. chloride, bicarbonate, biphosphate and sulfate)
Term
Cations
Definition
an ion bearing a negative charge (i.e. sodium, potassium, calcium, and magnesium)
Term
What is the difference in Active and Passive transport?
Definition
Passive transport requires no energy.

Active transport requires energy, usually in the form of ATP
Term
What are the differences between hypertonic, isotonic and hypotonic in relation to a cell?
Definition
Hypertonic causes fluid in the cell to rush out and the cell shrivels and becomes dehydrated.

Hypotonic causes the cell to draw in fluid and the cell swells.

Isotonic causes no reaction
Term
Define the fluids crystalloid and colloid
Definition
Crystalloid - most common IV solution used in emergency medicine. Contains water and electrolytes.

Colloid - a solution that contains large proteins that cannot pass through the capillary membrane.
Term
Different types of reactions- exchange decomposition, and synthesis
Definition
Exchange decomposition - breaks a molecule into smaller fragments. ( "AB" becomes "A" and '"B")

Synthesis - forms small molecules into larger molecules ("A" and "B" form "AB")
Term
What is the difference between osmosis and diffusion?
Definition
Osmosis is the diffusion of water molecules across a membrane.

Diffusion is when molecules move from an area of high concentration to an area of low concentration
Term
Nutrient
Definition
essental elaments and molecules obtained thru diet
Term
Metabolite
Definition
all of the molecules synthesized or broken down by chemical reactions
Term
Potential energy versus kenitic energy
Definition
Potential energy is stored energy (ADP)

Kenitic energy is energy of motion (ATP)
Term
What are buffers?
Definition
Compounds that stabilize pH by the addition or remove
Term
Arteriosclerosis vs Atherosclerosis
Definition
Arteriosclerosis - thickening and toughening of arterial walls

Atherosclerosis - the formation of lipid deposits in the tunica media (the middle layer)
Term
Veins vs Arteries
Definition
veins - takes blood from capillaries to the heart

arteries - takes blood from the heart to the capillaries
Term
Types of receptors in parsympethics system
Definition
Preganglionic - in the brain and in sacral segments of the spinal chord.

Ganglionic - in the peripheral ganglia within or adjacent to the target organs
Term
Respiratory diffusion
Definition
CO2 exits blood and O2 enters in the lungs
Term
Peripheral diffusion
Definition
O2 exits the blood into the body and CO2 enters the body.
Term
Areas of the diencephalon
Definition
epithalamus, the thalamus, and hypothalamus
Term
Synapesis of epineferine release vs ach release
Definition
Epinephrine - Skeletal muscle fibers, liver cells and cardiac muscle fibers

ACh - parasympathetic
Term
What is you limbic system responsible for?
Definition
contorls emotions, memories and behavioral drives
Term
Different types of memories
Definition
Short term and long term in terms of the duration of the memory.

Fact and skill in terms of type
Term
What is the Frank Starlings principle?
Definition
More in = More out
Term
Electrolyte movement in terms of polarization and depolarization?
Definition
Sodium in during depolarization

Potassium out during repolarization
Term
Differences in subdural, subarachnoid and epidural and what you find in there?
Definition
Term
What are fontanels
Definition
a soft flexible, fibrous region between two flat bones in the developing skull
Term
Difference in tissues (skeletal, smooth, cardiac, nervoius)
Definition
Skeletal- Long, cylindrical, striated, and multinucleate

Smooth- Short, spindle shaped, and non-striated with a single, central nucleus

Cardiac-Short, branched, and striated; usually has a single nucleus; interconnected by intercalated discs


Nervous- longest type of cell in body
Term
What does myelin do for neurons?
Definition
increases the speed in which a action potential travels along axon
Term
Ach – what type of neuron / areas
Definition
Located in brain and PNS. Dominate in PNS.
Term
5 functions of skeletal muscles
Definition
1) Produce movement
2) Maintain posture and body position
3) Support soft tissues
4) Guard entrances and exits
5) Maintain body temperature
Term
What are your pacemaker cells
Definition
cells in the SA node that set the pace of cardiac contraction
Term
What type of acid does midochonriria use to make ATP
Definition
pyruvic acid
Term
Depolarization / repolarization process
Definition
Depolorization - Sodium rushes into cell

Repolorization - Potassium exits cell
Term
The enzyme that breakes down ach
Definition
AChE
Term
Different types of fractures
Definition
Greenstick - Broke on one half and bent on other

Torus - swelling or buckling with little to no displacement

Transverse - A break perpendicular to the long axis of bone

Oblique - A break diagonally across bone

Spiral - break caused by a twisting force to the bone

Comminuted - a break with multiple fragments

Segmental - multiple breaks causing a floating segment of bone
Term
The parts of the heart in terms of blood flow
Definition
Left ventricle, left atrium, right atrium & right ventricle
Term
Different devision of the nervrious system
Definition
Peripheral Nervous System (PNS)

Central Nervous System (CNS)
Term
Efarent vs afarent – in terms of info transmission
Definition
Afferent - Caries information from receptors to the CNS (Cause)

Efferent -Carries information from the CNS to the Effectors (Response)
Term
Beta 1 receptors cause what – Dialate
Definition
Dilate the bronchioles
Term
What is a refractory period
Definition
the period between the initiation of an action potential and the restoration of the normal resting potential; during this period the membrane will not respond to more simulation
Term
Pulminory circuit vs systemic circuit (including heart side association)
Definition
Pulmonary Circuit is the lungs and is receives blood from the right ventricle and into the lungs. From the lungs, the blood returns to the left atrium.

Systemic circuit receives blood from the left ventricle and flows into all areas of the body other then the lungs and the returns to the heart in the right atrium.
Term
Different types of joints based on type of motion
Definition
Synarthrosis - No movement

Amphiarthosis - little movement

Diarthosis - Free movement
Term
Highest pressuere vs lowest pressure
Definition
highest pressure is found in the aorta

lowest pressure is found in the venae cavea
Term
Right coronary artery supplies what part of heart
Definition
the right atrium and portions of both ventricles
Term
Heart attack is mostly cause by

Term
What is hyper/hypo in terms of potassium and calcium
Definition
Term
Bradycardia and Tachicardia
Definition
Bradychardia is a slow heart beat

Tachicardia is a fast heart beat
Term
What is the fastest number contractions a heart can beat per minute
Definition
200
Term
stroke volume vs cardiac output
Definition
Stroke Volume - the amount of blood ejected by a single contraction of a ventricle

Cardiac Output - the amount of blood pumped by each ventricle in one minute
Term
Nerve that monitor baroreceptors
Definition
aortic sinuses, carotid sinuses, and right atrium
