Paoliteal
Back of knee
Plantar
Sole of foot
Oligosaccharides
Consist of 3-20 monsaccharides.
Internal
Within, or interior to
Lateral
Away from the midline
Cation
Ion with a positive charge.
pH scale
Measures the acidity alkalinity(basicity) of a solution and ranges from 0-14, with acid being below 7, alkaline above 7, and neutral at 7.
Cellular Level
Second level of organization.
Peripheral
Extending from the main part
Fibroblasts
Cells of areolar connective tissue.
Thoracic Cavity
Contains the heart and lungs.
Pathophysiology
The study of disorders of functioning.
Organ System Level
Fifth level of organization.
Cell Respiration
Energy production within cells. Glucose(food) and Oxygen combine to yield carbon dioxide, water, ATP and heat.
Pericardial Membranes
Serous membranes of the heart
Golgi Apparatus
Organelle for synthesis of carbohydrates and the packaging of materials for secretion from cell.
Centrioles
Organelle that organizes the spindle fibers during cell division.
DNA
Genetic code for the characteristics and activities of the cell.
Platelets
Prevent blood loss by causing clotting.
Genome
Total genetic information in a particular species (DNA).
Phospholipids
Diglycerides with a phosphate group in the third bonding site of glycerol. Part of cell membranes.
Nucleotide
Consists of a pentose sugar, a phosphate group and one of several nitrogenous bases.
Proteins
Made of smaller subunits called amino acids, which all contain carbon, hydrogen, oxygen and nitrogen.
Covalent Bond
The sharing of electrons between atoms.
Dosral Cavity
Contains the central nervous system, and consists of the cranial cavity and the vertebral or spinal cavity.
Proton
Has a positive electrical charge and is found in the nucleus (center) of the atom.
Visceral
Pertaining to the organs within a cavity
Ventral Cavity
Consists of two compartments, the thoracic and the abdominal cavity, which are separated by the diaphragm.
Hypertonic
A solution with a higher salt concentration than in cells.
Facilitated Diffusion
Movement of molecules through a membrane by carrier and transporter enzymes.
Tissues
A group of cells with similar structure and function.
Cuboidal Cells
Epithelial cells that are cube shaped.
Matrix
A structural network or solution of non-living intercellular material.
Haploid Number
Half the usual number of chromosomes.
Tissue
A group of cells with similar structure and function.
RNA
The other nucleic acid required to transcribe the genetic code in DNA into proteins.
Flagellum
Organelle that enables a cell to move.
Cartilage
The protein matrix does not contain calcium salts and contains more water than bone, making it more resilient than bone. It is firm, yet smooth and flexible.
Pleural Membranes
Serous membranes of the thoracic cavity.
Muscle Tissue
Specialized for contraction. When contracted, they shorten, bringing about movement.
Peritoneum
The serous membrane that lines the abdominal cavity.
Synapse
A small space where nuerons meet, which an electrical impulse cannot cross as it travels along the cell membranes.
Steroids
Consist of four rings of carbon and hydrogen. Cholesterol, produced in the liver and consumed in food, is the basic steroid from which the body makes others.
Organic Chemicals
Often very complex and always contain the elements carbon and hydrogen.
Plasma
Water found in blood vessels, part of ECF.
Chemical Bond
A force or attraction between positive ad negative electrical charges that keeps two or more atoms together to form molecules.
Transverse Section
A horizontal plane that separates the body into upper and lower portions.
Negative Feedback
When the body's response reverses a stimulus and keeps some aspect of the body within normal range.
Mitochondria
Organelle that is the site of aerobic cell respiration-ATP production.
Superficial Fascia
Connective tissue between the skin and muscle.
Endoplasmic Reticulum (ER)
Organelle that functions as a passageway for transport of materials within the cell and synthesis of lipids.
Myocardium
Cardiac muscle that forms the walls of the chambers of the heart.
Blood Pressure
Created by the pumping of the heart.
Concentration Gradient
The relative amounts of substance on either side of a membrane.
Adipose Tissue
The cells are called adipocytes and are specialized to store fat.
Messenger RNA (mRNA)
The intermediary molecule between the nucleus and the ribosmes in the cytoplasm.
Diffusion
The movement of molecules from an area of greater concentration to one of lesser concentration.
Disulfide Bond (bridge)
A covalent bond formed between two atoms of sulfur, usually within the same large protein molecule.
Hydrogen Bond
Forms a weak bond with other atoms because of slight positive charge of its proton.
Decomposition Reaction
Bonds are broken and a large molecule is changed to two or more smaller ones.
Buffer System
A chemical or pair of chemicals that minimizes changes in pH.
Organ System
A group of organs that all contribute to a particular function.
Homeostasis
When the body is stable and in good health.
ADP (adenosine diphosphate)
Energy released from food in cell respiration is used to synthesize ATP from ADP + P. When cells need energy, ATP is broked down to ADP+P.
Mucous Membranes
Line the body tracts and have openings to the environment.
Stratified Squamous Epithelium
Many layers of cells, surface cells flat; lower cells rounded.
Four Main Groups of Tissue
Epithelial, Connective, Muscle and Nerve.
Tranfer RNA (tRNA)
Picks up specific amino acids from food protein and brings them to their proper triplets on the mRNA.
Cell Membrane
Outermost boundary of a cell, made of phospholipids, protein, and cholesterol. Is selectively permeable and allows certain substances to enter or leave.
Frontal (coronal) Section
A plane from side to side that separates the body into front and back portions.
Functions of Sodium and Potassium
Necessary for muscle contraction and nerve impulse transmission
Diploid Number
The usual number of Chromosomes in a cell (46).
Fundtions of Phosphorus
Strong bones and teeth, part of DNA & RNA, part of cell membranes
