Medical Termanology Flashcards
Acid
Any substance that gives up hydrogen ions in a solution and has a pH below seven
Ion
A chemical particle that carries an electrical charge
Serous fluid
A watery serum like fluid, such as that secreted by the serous membrane of the peritoneum lining of the abdominal cavity
Sutures
In movable joints, that join the bones of the skull
Action potential
the passage of an impulse to an adjacent cell. An electrical message.
Ventilation
The movement of air in and out of the lungs
Villi
Fingerlike projections of certain cells, such as those lining the intestine to increase their surface area for absorption
Excitability
The property of being able to respond to a stimulus
Hormones
Any variety of molecules, that act as chemical messengers when secreted into the blood by the endocrine tissue
Alpha 1 receptors
A molecule in certain cells that bind with specific substances to produce a certain affect.
Example: blood vessels bind with epinephrine and norepinephrine to cause vasoconstriction .
Anaerobic metabolism
Cellular production of energy without oxygen
Electrolyte
A particle in your blood and other body fluid that carry an electrical charge
Embryo
A human organism from day 4 through 8 weeks after fertilization of an ovum.
Endothelium
Epithelial tissue, that lines, the inner surface of a structure
Extracellular fluid
All fluid within the body that is not within a cell
Perfusion
Providing nutrients oxygen and other substances, to the cellular level through the blood
Zygote
A cell formed by the union of a sperm and an egg
Respiration
A breath-
Gas exchange between the body and the environment
Respiratory membrane
The surface where gas exchange between the alveolar eye and blood occurs within the lungs
Bicarbonate
An an-ion (HCO3), a base. Helps keep a normal acid base (pH) balance.
pH
The measurement of acidity, or alkalinity of a substance.
0-14
0-the most acidic
7-neutral
14-most alkaline
Hemoglobin
Iron containing protein in red blood cells that carry oxygen to your organs and tissues and transport carbon dioxide back to the lungs
Insulin
A hormone secreted by the beta cells of the pancreas in response to increased glucose levels.
Insulin is necessary for adequate amounts of glucose to enter cells.
Cardiac
The heart
Arthralgia
Joint pain
Diffuse
Particles move from a higher concentration area to a lower concentration area until equilibrium is reached.
Optic
Vision
Cervical
The neck
Hepatic
The liver
Reno
The kidney
Osmosis
The movement of water through a semipermeable membrane from a lower concentrated solution to a higher concentrated solution to achieve equilibrium
Cerebrospinal fluid
Fluid around the brain, and the spinal cord secreted from special cells in the ventricles of the brain
Hemostasis
The stable internal environment of the body
Osmotic pressure
The force it takes to pass water through a semipermeable membrane
Epithelial tissue
Layers of cells that cover or line, a structure, allowing for protection, absorption, secretion and other specialized functions
Abduction
movement away the midline
Adduction
Movement towards the midline
Anterior
Front
Apex
The tip of a structure
Base
Lower part of a structure
Caudal
Towards the feet
Cephalad
Towards the head
Deep
Towards the inside of the body
Distal
Away from
Dorsal
Back
Extension
Straightening of a joint
Flexion
Bending of a joint
Inferior
Below
Lateral
Towards the side
Midline
Vertical line dividing the left and right sides of the body
Posterior

Prone
Lying face down
Proximal
Near the midline
(The elbow is proximal to the hand)
Superior
Above
Supine
Lying on your back
Ventral
Towards the front
Atrophia
Reduction of the size of cells in a tissue
Metaplasia
A Change in the type of cells within the tissue to a different type of cells than is not normal
Hyperplasia
Increase in the number of cells within a tissue
Hypertrophy
Increase in size of the cells of a tissue
Anaplasia
Poor cellular response
Dyspraxia
Delayed response and maturation of a cell
Neoplasia
A new or extended growth of the area. A tumor.
Apoptosis
Instructions provided by DNA that Command cellular self-destruction
Emphysema
Decrease surface area within the alveoli
Chronic Bronchitis
Mucus and inflammation within the bronchiole
Metabolic acidosis
pH is less then 7.35
Decreased blood pH and decrease in biocarbonate level in the blood
Alkalosis
pH higher then 7.45
Inotropic
Increased contractility
Dromotropic
Increase rate of conduction through the AV node
Chronotropic
Increase heart rate
Lusitropic
Increases relaxation of the heart
